MPLS is a technology that allows traffic to be forwarded through networks based on short fixed length labels rather than long network addresses, enabling traffic engineering and quality of service. It works by classifying packets into forwarding equivalency classes, assigning labels when packets enter the MPLS domain, and using label switching to forward packets along label switched paths. MPLS provides advantages like simplified packet forwarding, efficient traffic engineering capabilities, and virtual private networks.
Overview of the MPLS backbone transmission technology.
MPLS (MultiProtocol Layer Switching) is a layer 2.5 technology that combines the virtues of IP routing and fast layer 2 packet switching.
IP packet forwarding is not suited for high-speed forwarding due to the need to evaluate multiple routes for each IP packet in order to find the optimal route, i.e. the route with the longest prefix match.
However, Internet Protocol routing provides global reachability through the IP address and through IP routing protocols like BGP or OSPF.
Layer 2 packet switching has complementary characteristics in that it does not provide global reachability through globally unique addresses but allows fast packet forwarding in hardware through the use of small and direct layer 2 lookup addresses.
MPLS combines IP routing and layer 2 switching by establishing layer 2 forwarding paths based on routes received through IP routing protocols like BGP or OSPF.
Thus the control plane of an MPLS capable device establishes layer 2 forwarding paths while the data plane then performs packet forwarding, often in hardware.
MPLS is not a layer 2 technology itself, i.e. it does not define a layer 2 protocol but rather makes use of existing layer 2 technologies like Ethernet, ATM or Frame Relay.
This document provides an overview of MPLS (Multi-Protocol Label Switching). It discusses the basic idea behind MPLS, the history and components. MPLS assigns labels to IP flows to create label switched paths between ingress and egress routers. Routers forward packets based on lookups of these labels rather than long IP addresses. MPLS supports traffic engineering and quality of service across networks while integrating technologies like IP, ATM, and Frame Relay.
The document provides an introduction to MPLS (Multi-Protocol Label Switching) technology. It discusses the goals of MPLS including understanding the business drivers, market segments, problems addressed, benefits, and major components. The key components of MPLS technology are explained, including MPLS forwarding and signaling, label distribution protocols, MPLS network services like VPNs, QoS, and traffic engineering.

BGP is the exterior gateway protocol that connects different autonomous systems on the internet. It allows for the exchange of routing and reachability information between these systems. BGP operates using a finite state machine to manage the states of connections between peers. It establishes TCP connections between routers to exchange routing updates and keep connections alive through regular keepalive messages. BGP version 4, defined in RFC 4271, is the current standard implementation which supports features like classless inter-domain routing and route aggregation.
VRRP (Virtual Router Redundancy Protocol) is a computer networking protocol that provides for
automatic assignment of available Internet Protocol (IP) routers to participating hosts. This increases the
availability and reliability of routing paths via automatic default gateway selections on an IP subnetwork.
The Virtual Router Redundancy Protocol (VRRP) eliminates the single point of failure inherent in the
static default routed environment. VRRP specifies an election protocol that dynamically assigns
responsibility for a virtual router (a VPN 3000 Series Concentrator cluster) to one of the VPN
Concentrators on a LAN. The VRRP VPN Concentrator that controls the IP address(es) associated with a
virtual router is called the Master, and forwards packets sent to those IP addresses.
VLANs logically segment LANs into broadcast domains by using switches to assign ports and their attached devices to VLAN groups based on their MAC address, IP subnet, or switch port. This allows devices that are physically located on different floors or buildings to belong to the same logical LAN segment while preventing Layer 2 broadcasts from crossing VLAN boundaries. VLAN trunk links between switches allow multiple VLANs to be transmitted over the same physical link.
VXLAN is a protocol that allows large numbers of virtual LANs to be overlaid on a physical network by encapsulating Ethernet frames within UDP packets and transporting them over an IP network. It addresses the scalability limitations of VLANs in large multi-tenant cloud environments by using a 24-bit segment ID rather than a 12-bit VLAN ID. The document provides an overview of VXLAN, why it is used, key concepts like VTEPs and VNIs, and demonstrations of VXLAN configuration on Cisco and Arista switches.
This document provides an overview of MPLS basics:
- MPLS integrates Layer 2 switching and Layer 3 routing to satisfy networking requirements for various applications. It groups packets into forwarding equivalence classes (FECs) and assigns each FEC a label.
- Label switching routers (LSRs) establish label switched paths (LSPs) to forward labeled packets hop-by-hop through the MPLS network. The ingress LER labels incoming packets and the egress LER removes labels before forwarding.
- MPLS supports technologies like VPNs and traffic engineering to provide benefits like address multiplexing, QoS, and traffic control capabilities.
This document discusses VLAN Trunking Protocol (VTP) which allows switches to exchange VLAN configuration information and manage VLANs across multiple switches. It describes VTP domains, modes, advertisements and pruning. VTP is configured on switches to synchronize VLAN information and eliminate incorrect configurations. Troubleshooting tools like "show vtp status" and "show interfaces trunk" are used to verify proper VTP configuration and trunking.

Finally, there is a detailed description of the LTE/LTE - A evolution and the feature requirements made on the transport network. There will be detailed analysis of different LTE models and also some technical enhancements and proposals considered for the implementation of LTE in a Unified MPLS environment.
LDP allows MPLS routers to exchange label mapping information by establishing LDP sessions between peers. LDP defines procedures and messages for routers to advertise label bindings and establish label switched paths for forwarding traffic. LDP sessions can be directly connected over a single hop or nondirectly connected over multiple hops using targeted Hellos.
This document provides an introduction to Multi-Protocol Label Switching (MPLS), including its motivation, basic concepts, components, protocols, operation, advantages, and disadvantages. MPLS combines IP routing with ATM switching to address some of the limitations of IP routing, such as lack of quality of service, while being less complex and expensive than ATM. It works by assigning short, fixed-length labels to IP packets at the edge of the network which are then used for fast packet forwarding within the network core.
This document discusses the value of MPLS-TP for utility networks. It begins with an introduction of ECI, an expert in telecommunications solutions. It then discusses the transition from TDM to packet-based networks for utilities and the key challenges in maintaining strict service requirements. MPLS-TP is presented as a solution, combining the efficiency of packet networks with the predictable performance of TDM. MPLS-TP retains key aspects of MPLS while adding transport-grade operations. It provides deterministic performance for applications like teleprotection and synchronization. Overall, the document argues that MPLS-TP is well-suited for mission critical utility applications by enabling a risk-free transition to packet-based networks with TDM-grade reliability

“MPLS is that it’s a technique, not a service.”
The fundamental concept behind MPLS is that of labeling packets. In a traditional routed IP network,
each router makes an independent forwarding decision for each packet based solely on the packet’s
network-layer header. Thus, every time a packet arrives at a router, the router has to “think through”
where to send the packet next.
MPLS (Multiprotocol Label Switching) es un mecanismo estándar creado por la IETF que opera entre la capa de enlace de datos y la capa de red del modelo OSI para unificar el servicio de transporte de datos en redes basadas en circuitos y paquetes asignando etiquetas únicas a los flujos de datos. MPLS permite ofrecer calidad de servicio independientemente de la red subyacente etiquetando los paquetes según criterios de prioridad y asignándolos a rutas con baja carga. Las principales aplicaciones de MPLS
NAT is used to translate private IP addresses to public IP addresses to allow access to the internet. There are different types of NAT including static NAT for one-to-one mapping, dynamic NAT for mapping multiple private addresses to public addresses from a pool, and NAT overload/PAT which maps multiple private addresses to a single public address using port addressing. The document provides configuration examples for static, dynamic, and overload NAT on a Cisco router.

The project was started with a sole aim in mind that the design should be able to recognize the voice of a person by analyzing the speech signal. The simulation is done in MATLAB. The design of the project is based on using the Linear prediction filter coefficient (LPC) and Principal component analysis (PCA) on data (princomp) for the speech signal analysis. The Sample Collection process is accomplished by using the microphone to record the speech of male/female. After executing the program the speech is analyzed by the analysis part of our MATLAB program code and our design should be able to identify and give the judgment that the recorded speech signal is same as that of our desired output.
Network Address Translation (NAT) allows a single device like a router to act as an agent between a private network and the public internet using a single public IP address. This conserves limited public IP addresses as only the NAT device needs a public IP, while an entire private network can use private IP addresses. NAT works by translating the private IP address and port of devices in the private network to the public IP address and unique port of the NAT device when communicating with the public internet, and vice versa for incoming traffic. This allows all private network devices to access the internet through the single public IP address of the NAT device.

Multi-Protocol Label Switching has become by far one of the most important Internet technologies of the last 15 years. From humble beginnings back in 1996-97, it is literally the defacto standard in a large majority of service provider networks today. This presentation, delivered to executives at MTNL, Mumbai (a large regional carrier in India), explains the key operational principles behind MPLS, and its significant applications.
This document summarizes a seminar presentation on face recognition using neural networks. It discusses face recognition, neural networks, the steps involved which include pre-processing, principle component analysis, and back propagation neural networks. Advantages of neural networks for face recognition are robustness to variations in faces and ability to learn from data. Face recognition has applications in security and identification.
This presentation summarizes the Cisco Certified Network Associate (CCNA) certification and covers networking concepts relevant to the CCNA including networking devices, the OSI model, IP addressing, routing, access lists, network address translation, switches, virtual LANs, WAN connection types, wireless technology, and comparisons of 802.11 wireless standards.
Routers forward data packets between networks while switches operate at the data link layer and forward packets within a local area network. Hubs simply broadcast all incoming data to all ports. The document provides answers to common CCNA interview questions about networking fundamentals like IP addressing, routing, switching, protocols and Cisco router components.
Quality of service refers to a network's ability to provide reliable communication through factors like error rates, bandwidth, throughput, transmission delay, availability, and jitter. These factors influence a network's capability to deliver secure and reliable service. Measuring these QoS factors allows efficient use of network resources and comparison of different networks' overall performance.
This document describes a CCN CEP project involving 3 group members to simulate a LAN network. The project involves configuring IP addresses, routers, servers, and VLANs. Connectivity is tested using ping commands between devices like PCs, servers, and across VLANs which are successful. Basic network functions like email and web access are also verified to work as intended. The simulation validates the network design and configuration.
Location convenience is an important factor for customers when choosing a financial institution, as customers prefer banks that have branches or ATMs located near their home or work within 2 km. To increase convenience and competitiveness, banks aim to expand their branch and ATM networks, which can be done organically by building new locations or inorganically by acquiring existing networks from competitors or partners, though acquired networks may not complement existing networks perfectly due to coverage overlap.

It provides an introduction to networking and covers topics such as network types (LAN and WAN), network models (OSI model), networking cables, devices, IP addressing, routing, firewalls, wireless networks, and ISDN. The report defines what a computer network is, outlines the requirements and benefits of networking, and describes different network components and concepts at a high level.
The document discusses several topics related to computer networking including network topologies, physical and logical topologies, OSI and TCP/IP models, IP addressing, subnetting, routers, routing protocols, VLANs, and data flow diagrams. It provides information on LAN/MAN/WAN standards, the seven layers of the OSI model, classes of IP addresses, configuring router interfaces, routing protocols like OSPF and EIGRP, using VLANs to segment networks, and creating basic data flow diagrams.
This document discusses various topics related to WAN technologies including backup and restoration of Cisco IOS images, resolving hostnames, WAN connection types, encapsulation protocols, and an overview of technologies like ISDN, Frame Relay, ATM, and PPP. Specific configuration examples are provided for setting up PPP and CHAP authentication between two routers over a serial interface.
The document discusses how application architects traditionally focused on solving IO bottlenecks in servers by offloading processing to intelligent network interface cards. With modern distributed applications spanning thousands of servers, application architects now must consider network topology, segmentation, and control plane protocols to optimize latency and bandwidth. The rise of virtualization and cloud computing has changed traffic patterns in datacenters from north-south traffic to dominant east-west traffic between servers. This requires new datacenter fabric designs beyond the traditional three-tiered topology.
Everything you need to know about network troubleshooting can be learned in elementary school. Networking involves hardware and software that allows computers to communicate. No two networks are exactly alike. Basic network components include end stations, applications, and the network itself. The OSI model provides a standard way to understand how data moves through a network via different layers. TCP/IP is the most common network protocol and uses IP for addressing and routing and TCP for reliable data delivery. Gathering basic network statistics is an important part of troubleshooting.
This document discusses network architecture and design. It covers component architectures, addressing and routing architectures, network management architecture, performance architecture, and security architecture. Some key points include:
- Component architecture describes how network functions are applied using hardware and software mechanisms.
- Addressing involves applying identifiers to network devices, while routing learns connectivity and forwards packets. Common addressing mechanisms include subnetting, super-netting, dynamic addressing, and private/public addressing.
- Network management architecture provides functions for controlling, planning, and monitoring network resources using mechanisms like monitoring, instrumentation, and configuration.
- Performance architecture allocates network resources to users and applications using mechanisms like quality of service, resource control, service level agreements, and policies.
Chapter 11 Selecting Technologies and Devices for Enterprise Netwo.docxbartholomeocoombs
Chapter 11 Selecting Technologies and Devices for Enterprise Networks This chapter presents technologies for the remote-access and wide-area network (WAN) components of an enterprise network design. The chapter discusses physical and data link layer protocols and enterprise network devices, such as remote-access servers, routers, firewalls, and virtual private network (VPN) concentrators. The chapter begins with a discussion of the following remote-access technologies: Point-to-Point Protocol (PPP) Cable modems Digital subscriber line (DSL) After discussing remote-access technologies, the chapter presents options for selecting WAN and remote-access capacities with the North American Digital Hierarchy, the European E system, or the Synchronous Digital Hierarchy (SDH). The chapter continues with a discussion of the following WAN technologies: Leased lines Synchronous Optical Network (SONET) Frame Relay Asynchronous Transfer Mode (ATM) Metro Ethernet The chapter then covers two topics that will help you complete your WAN design: Selecting routers for an enterprise WAN design Selecting a WAN service provider The chapter concludes with an example of a WAN network design that was developed for a medium-sized company, Klamath Paper Products, Inc. The example indicates what technologies and devices were chosen for this customer based on the customer’s goals. The technologies and devices you select for your particular network design customer will depend on bandwidth and quality of service (QoS) requirements, the network topology, business requirements and constraints, and technical goals (such as scalability, affordability, performance, and availability). An analysis of traffic flow and load, as discussed in Chapter 4, “Characterizing Network Traffic,” can help you accurately select capacities and devices. For some organizations, scalability is a key design goal. The selected WAN solution must have enough headroom for growth. As discussed in this chapter, some WAN technologies are more scalable than others. Another key design goal for many organizations is to minimize the cost of WAN and remote-access circuits. Optimization techniques that reduce costs play an important role in most WAN and remote-access designs. Methods for merging separate voice, video, and data networks into a combined, cost-effective WAN also play an important role. These methods must handle the diverse QoS requirements of different applications. Remote-Access Technologies As organizations have become more mobile and geographically dispersed, remote-access technologies have become an important ingredient of many enterprise network designs. Enterprises use remote-access technologies to provide network access to telecommuters, employees in remote offices, and mobile workers who travel. An analysis of the location of user communities and their applications should form the basis of your remote-access design. It is important to recognize the location and number of full- and part-time t.

The document discusses various topics related to creating larger computer networks, including modems, digital telephone lines, remote access, and protocols like PPTP. Modems are primarily used to transfer files between computers by uploading and downloading. Digital telephone lines like DSL and cable modems provide higher speed data transmission compared to standard analog lines. Remote access allows employees to securely access a corporate network from outside using protocols like PPTP, which creates private "tunnels" within public networks like the Internet.
Routers are networking devices that forward packets between logical networks. They are used to extend or segment large internetworks and connect TCP/IP networks and local area networks to the Internet. Routers have advanced features for quality of service, traffic filtering, and encryption. Switches offer intelligence beyond basic hubs and can read MAC addresses to selectively forward frames to specific ports. Bridges divide a network into segments and filter traffic between segments based on MAC addresses. Gateways connect networks that use different protocols by operating at the network layer.

7. IP is an address of a Computer on a network.
task of delivering datagrams from the source host to the destination host
solely based on the addresses.
Two IP version-IPv4 and IPv6
IPv4(Internet Protocol version 4)for 32 bits
IPv6(Internet Protocol version6)for 128 bits
Type of IP Address
Static IP Address (Automatically assign)
Dynamic IP Address (Manually assign)
8. There are five classes available in IP range
Class A- 1.0.0.1 to 126.255.255.254
Class B- 128.1.0.1 to 191.255.255.254

Class E- for research and developing centre
10.
11. With the rapid growth of the internet & the ever-
increasing demand for new addresses, the standard
address class structure has been expanded by
borrowing bits from the Host portion to allow for
more Networks.
There are default standard subnet masks for Class A,
B and C addresses:
12. The PING (Packet Internet Groper) command
verifies OSI Layer 3 (Network Layer) connectivity.
The subnet mask is the same for all users on a
specific network.
Internet routing devices traditionally have been called
gateways
A network gateway is an internetworking system capable of joining
together two networks that use different base protocols.
13. A choke point of control and monitoring .
Interconnects networks with differing trust.
Imposes restrictions on network services.
only authorized traffic is allowed
Improve network security & reduce risks to hosts
14. Characterized by protocol level it controls in
Packet filtering (filter incoming & outgoing data)
Circuit gateways (large network filter)
Application gateways (Need separate proxies for each service)
Combination of above is dynamic packet filter
15. Internet communication is a accomplished by exchange
of individual ‘packets’ of data.
Each packet is transmitted by its source machine
toward its destination machine.
Connection is actually comprised
Of individual packets travelling
b/w two machine.
If ‘agree’ it means connect or it will
be resend back to the machine.

17. Firewall cannot prevent Virus and Trojans
from the accessing the internet.
Mostly virus and trojan are received via e-mail
direct downloading ,etc
Firewall not really protect the system from hackers
(or any ultra surf)
Hard to upgrade
Take up physical space

20. Multi Protocol Label Switching is arranged between
Layer 2 and Layer 3
Versatile solution:-speed ,QOS ,traffic management
Security management.
21. Mechanisms to manage traffic flows of various
granularities (Flow Management)
Is independent of Layer-2 and Layer-3 protocols
Maps IP-addresses to fixed length labels
Supports ATM, Frame-Relay and Ethernet
23. • Short fixed length entity
20-bits label value
Each label head contain four fields
Label Format
24. • Resides at the edge of an MPLS network and assigns and
removes the labels from the packets.
• Support multiple ports connected to dissimilar networks (such as
frame relay, ATM, and Ethernet).
25. • Is a high speed router in the core on an MPLS network.
• ATM switches can be used as LSRs without changing their
hardware. Label switching is equivalent to VP/VC switching.
26.
27. • An application layer protocol for the distribution of label
binding information to LSRs.
• It is used to map FECs to labels, which, in turn, create LSPs.
• LDP sessions are established between LDP peers in the
MPLS network (not necessarily adjacent).
28. • In MPLS, traffic engineering is inherently provided using explicitly
routed paths.
• The LSPs are created independently, specifying different paths that
are based on user-defined policies. However, this may require
extensive operator intervention.
• RSVP-TE and CR-LDP are two possible approaches to supply
dynamic traffic engineering and QoS in MPLS.
29. • Improves packet-forwarding performance in the network
• Supports QoS and CoS for service differentiation
• Supports network scalability
• Integrates IP and ATM in the network
• Builds interoperable networks
30. Unknown knowledge of the technology
Miscommunication of networks still occur
Near replacement of MPLS technology has to be put
in place of old technology
Hardware problems
Better security needs to be implemented so hackers
cannot get into technology
