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 how MPLS enables service providers to offer managed shared services for greater profitability. It outlines Cisco's MPLS strategy, including providing basic IP connectivity initially and then adding functionality over time to support advanced services like traffic engineering, multicast VPNs, and network management. This allows migrating from just connectivity to shared services like NAT, DHCP relay, and virtual router redundancy, improving efficiency and opening new revenue streams.
The document provides housekeeping notes for a Cisco Connect Toronto 2015 session. It reminds attendees to silence electronic devices, provides information on how to provide feedback and enter a prize drawing, and advertises the Cisco dCloud platform and Cisco Spark collaboration app. It also includes an agenda for the session on access network evolution, next generation EPN architecture, network services evolution, and SDN evolution.
MPLS VPN provides a way to extend private network connectivity over a shared public infrastructure in a secure manner. It utilizes MPLS to create virtual point-to-point connections between customer sites. There are two main types of MPLS VPNs - Layer 3 VPNs which use extensions to BGP to exchange routing information between customer edge routers and provider edge routers, and Layer 2 VPNs which extend customer layer 2 networks across the MPLS backbone by encapsulating layer 2 frames with labels.

MPLS provides motivation to converge voice and data on a single network with increasing traffic demands. It works by assigning labels to packets based on forwarding equivalence classes. Labels are distributed through protocols like LDP and are used to forward packets along label switched paths through label swapping without deep packet inspection. MPLS enables features like traffic engineering, QoS, and virtual private networks.
1. MPLS simplifies forwarding by introducing label switching which uses a forwarding table and label carried in each packet rather than conventional IP routing based on IP addresses.
2. MPLS establishes label switched paths between routers where each router along the path transmits the packet to the next router by means of a label. Edge routers analyze packets and assign an initial label.
3. The main benefits of MPLS include improved performance, scalability, and traffic engineering capabilities compared to conventional IP routing.

Presentation on MPLS (Multi Protocol Label Switching)BalaMurugan948
MPLS is a routing technique that establishes an end-to-end path between a source and destination using labels. It builds a connection-oriented service on IP networks by using labels to set up the path in a hop-by-hop manner. MPLS makes IP routing faster by reducing the number of routing lookups and eliminates the need to run routing protocols on all devices. It is protocol independent and maps IP addresses to fixed length labels to forward traffic.

VPNs, Tunneling, and Overlay Networks
Virtual private networks (VPNs) allow private networks to be extended over public networks like the internet. VPNs provide benefits like extended communication, reduced costs, and improved productivity. There are two main types of VPNs: remote-access VPNs which connect users to a private network from various locations, and site-to-site VPNs which connect organizations' remote sites into a private network or allow organizations to share environments. Tunneling protocols like PPP and protocols like IPsec are used to securely encapsulate and transmit data across VPNs. Multiprotocol Label Switching (MPLS) and overlay networks are additional methods to improve network performance and security.
Voice over MPLS (VoMPLS) allows multiple voice calls to be transported efficiently over a single MPLS label switched path (LSP) by reducing header overhead. There are three modes of carrying voice in MPLS networks, depending on requirements. VoMPLS uses LSPs to provide predictable quality of service for voice packets by multiplexing multiple calls into primary and control subframes that are transmitted together within an MPLS frame. This provides an efficient mechanism for voice transport that reduces costs compared to traditional circuit-switched networks.
EVPN in Service Provider network
- EVPN allows service providers to create new revenue streams through network fabric designs that provide Ethernet Layer 2 and Layer 3 services. It protects investments by unifying networks on a single overlay and simplifying protocols and operations. EVPN can be deployed easily through seamless integration with existing networks and provides the same operational experience as IP VPNs.
The document discusses the transition to carrier Ethernet networks and the opportunities it provides. Key points include:
- Carrier Ethernet can help meet massive data growth and 4G/LTE applications by leveraging existing wireline infrastructure.
- It provides new revenue opportunities for service providers through mobile backhaul and wholesale services.
- Transitioning to Ethernet reduces operational costs compared to legacy TDM networks and allows incremental bandwidth increases at lower cost.

It covers VPN concepts like overlay and peer models, benefits of MPLS VPNs, and how routing information is propagated between provider edge (PE) routers using MP-BGP. Key aspects include using virtual routing and forwarding (VRF) instances to isolate customer routes, extending prefixes with route distinguishers (RDs) to handle overlapping addresses, and exchanging VPN routes between PE routers in the provider network.
This document proposes evolving carrier Ethernet architecture by combining segment routing and SDN technologies. Segment routing uses IS-IS or OSPF extensions to distribute MPLS labels without LDP. This simplifies network infrastructure while providing rich converged services with high availability and agility. Unified MPLS currently addresses challenges but is complex; segment routing and SDN could accelerate service deployment and reduce complexity by reducing management protocols. The proposal uses segment routing for transport and SDN for centralized service layer control.
The document provides information about an upcoming training course on deploying MPLS L3 VPNs. It includes details about the trainers, Nurul Islam Roman and Jessica Wei, their backgrounds and areas of expertise. It also outlines the course agenda which will cover topics such as MPLS VPN models, terminology, operation, configuration examples and service deployment scenarios.
This document discusses Voice over MPLS (VoMPLS) as an improved solution for carrying voice traffic compared to Voice over IP (VoIP). It provides an overview of VoMPLS, including how it uses MPLS encapsulation and framing to provide lighter encapsulation than VoIP, while still guaranteeing quality of service. The document also compares IP and MPLS network models, highlighting how MPLS addresses limitations of IP like lack of guaranteed paths, slow routing lookups, and inability to differentiate services. VoMPLS is concluded to be a better future solution for transporting voice due to its inherited advantages from MPLS like reliability, scalability and ease of implementation.
The L2 NID based architecture for vCPE/NFV deployments faces several challenges:
1) It can cause MAC address scale issues in the NFV data center switching infrastructure as thousands of customer MAC addresses may need to be learned.
2) It extends customer layer 2 domains to the NFV data center, increasing security risks from misconfigured customer networks.
3) There is a potential risk of layer 2 loops occurring between customer networks and the service provider infrastructure without proper demarcation and loop prevention.
4) Achieving high availability between redundant vCPE instances requires reliable tracking of the connectivity between the L2 NID and vCPE, which adds complexity.

Editor's Notes
What happened in Mumbai recently on 26/7 is critically similar to 9/11 in New York whereby the business had come to a stand-still. Many enterprises were greatly affected which also lead to complete destruction of business. This has given rise to the facts that emergencies have no boundaries, disasters are unavoidable and the need to establish Disaster Recovery Solution. This is of prime importance for enterprise customers who are dependent on data communication for business requirements. All this has forced all of us to do some rethinking.
