Overview of VPN protocols.
VPNs (Virtual Private Networks) are often viewed from the perspective of security with the goal of providing authentication and confidentiality.
However, the primary purpose of VPNs is to connect 2 topologically separated private networks over a public network (typically the Internet).
VPNs basically hook a network logically into another network so that both appear as one private local network.
Security is a possible add-on to VPNs. In many cases it makes perfectly sense to secure the VPNs communication over the unsecure public network.
VPN protocols typically employ a tunnel where data packets of the local network are encapsulated in an outer protocol for transmission over the public network.
The most important VPN protocols are IPSec, PPTP and L2TP. In recent years SSL/TLS based VPNs such as OpenVPN have gained widespread adoption.

An Introduction to the SIP protocol.
SIP Position in telecommunication networks and the content services.
What is SIP:
The Session Initiation Protocol (SIP) is a signaling communications protocol, widely used for controlling multimedia communication sessions such as voice and video calls over Internet Protocol (IP) networks.
The protocol defines the messages that are sent between peers which govern establishment, termination and other essential elements of a call. SIP can be used for creating, modifying and terminating sessions consisting of one or several media streams. SIP can be used for two-party (unicast) or multiparty (multicast) sessions. Other SIP applications include video conferencing, streaming multimedia distribution, instant messaging, presence information, file transfer, fax over IP and online games.

A virtual private network gives secure access to LAN resources over a shared network infrastructure such as the internet. It can be conceptualized as creating a tunnel from one location to another, with Encrypted data traveling through the tunnel before being decrypted at its destination.
Virtual private networks (VPNs) use public telecommunication networks like the Internet to provide secure connections between remote locations. VPNs encrypt data packets and transmit them through tunnels, encapsulating one protocol within another, to maintain private networks virtually. This allows remote access and site-to-site connectivity while reducing costs compared to traditional private networks using leased lines.
This document discusses virtual private networks (VPNs). It defines a VPN as a private network that uses a public network like the Internet instead of leased lines. VPNs provide secure remote access to corporate resources over the Internet and connect branch office networks to head office networks securely. The document outlines common VPN protocols like PPTP, L2TP, and IPsec. It discusses VPN components such as user authentication, address management, data encryption, and key management. Finally, it highlights benefits of VPNs such as reduced costs and increased flexibility compared to leased lines.
Virtual private networks (VPNs) allow for secure data transmission over public networks like the Internet. VPNs create virtual tunnels between devices to securely transmit encrypted data. There are three main types of VPNs: remote-access VPNs for remote users, intranet-based site-to-site VPNs to connect locations within a company, and extranet-based site-to-site VPNs to connect companies. VPNs use protocols like IPsec and SSL to encrypt data and tunneling protocols to transmit data securely between devices.
A VPN allows users to securely access a private network over a public network like the internet. It uses authentication, encryption, and tunneling protocols to protect data confidentiality and integrity. VPNs enable remote access for employees and connectivity between branch offices. Common VPN protocols include PPTP, L2TP, and IPSec which use encryption methods to secure data transmission over the VPN tunnel. VPNs provide benefits like reduced costs, flexibility, and scalability compared to private networks.
VPNs extend private networks over shared public infrastructure like the internet. VPNs use encryption and tunneling to provide secure connectivity similar to a private network but at lower cost. Common VPN types include remote access VPNs for mobile users, intranet VPNs for connecting multiple company sites, and extranet VPNs for connecting to business partners. VPNs can reduce networking costs and improve flexibility while maintaining security.
VPN allows organizations to connect remote sites and users over a shared public network while maintaining privacy and security. It uses encryption, authentication, and tunneling protocols to create a secure connection between devices. VPNs can extend an organization's intranet to remote offices, partners, suppliers and customers. They reduce costs compared to dedicated private networks. However, VPNs still face security risks from hacking attacks, weak authentication, client-side vulnerabilities, and malware infections that could compromise the private network. Proper firewalls, encryption, authentication and other security measures are needed to ensure VPN safety.
In VPNs, "tunneling" refers to the process of encapsulating VPN packets within regular IP packets in order to transmit them securely over the public Internet or other untrusted networks. This creates a "tunnel" through which the VPN traffic can travel.
Virtual private networks (VPNs) allow secure connections over public networks like the Internet. VPNs use encryption and tunneling technologies to securely connect remote offices, mobile users, and partners to a company's private network. There are two main types of VPNs - remote access VPNs for mobile and remote users, and site-to-site VPNs for connecting branch offices. VPNs provide security, lower costs, improved connectivity, and enable access to corporate resources anywhere via the Internet.

VPNs lower networking costs compared to private WANs and facilitate remote access and extranet connections with better performance than traditional dial-up.
This document provides an introduction to virtual private networks (VPNs). It defines the key terms "virtual," "private," and "network" that make up a VPN. The document outlines basic VPN requirements like user authentication, address management, data encryption, and key management. It describes the main types of VPNs: remote access, intranet, and extranet. Remote access VPNs allow mobile users to connect to an organization's network. Intranet VPNs connect organization offices over the internet. Extranet VPNs are similar but connect external users like customers or suppliers. The document also discusses tunneling, which encapsulates data packets for transmission, and lists some advantages and disadvantages of using VPNs.
In VPNs, "tunneling" refers to the process of encapsulating packets from one protocol inside the packets of another protocol. This allows VPNs to work by creating a "tunnel" between two endpoints and encapsulating all traffic inside that tunnel to maintain privacy and security as it travels over an otherwise public network.
In VPNs, "tunneling" refers to the process of encapsulating packets from one protocol inside the packets of another protocol. This allows VPNs to work by creating a virtual circuit across the public network to mimic the behavior of a point-to-point private connection.
VPN allows remote users to securely connect to a private network over the public Internet. It uses protocols like PPTP and L2TP to encapsulate data and send it through an encrypted tunnel. The VPN server must be configured to assign clients an IP address and authenticate users, while the VPN client needs to be set up to connect to the server and access the private network resources. Encryption protects the data in transit between the client and server.
This document provides an overview of virtual private networks (VPNs). It defines a VPN as a private network that uses public telecommunication networks like the Internet instead of leased lines. It discusses the main types of VPNs including remote access, site-to-site intranet, and site-to-site extranet. The document also covers VPN protocols, security features, devices, advantages like reduced costs, and disadvantages like reliance on internet connectivity. It concludes that VPNs provide a secure and cost-effective private networking solution for many companies.

An All-Around Benchmark of the DBaaS MarketScyllaDB
The entire database market is moving towards Database-as-a-Service (DBaaS), resulting in a heterogeneous DBaaS landscape shaped by database vendors, cloud providers, and DBaaS brokers. This DBaaS landscape is rapidly evolving and the DBaaS products differ in their features but also their price and performance capabilities. In consequence, selecting the optimal DBaaS provider for the customer needs becomes a challenge, especially for performance-critical applications.
To enable an on-demand comparison of the DBaaS landscape we present the benchANT DBaaS Navigator, an open DBaaS comparison platform for management and deployment features, costs, and performance. The DBaaS Navigator is an open data platform that enables the comparison of over 20 DBaaS providers for the relational and NoSQL databases.
This talk will provide a brief overview of the benchmarked categories with a focus on the technical categories such as price/performance for NoSQL DBaaS and how ScyllaDB Cloud is performing.

Elasticity vs. State? Exploring Kafka Streams Cassandra State StoreScyllaDB
kafka-streams-cassandra-state-store' is a drop-in Kafka Streams State Store implementation that persists data to Apache Cassandra.
By moving the state to an external datastore the stateful streams app (from a deployment point of view) effectively becomes stateless. This greatly improves elasticity and allows for fluent CI/CD (rolling upgrades, security patching, pod eviction, ...).
It also can also help to reduce failure recovery and rebalancing downtimes, with demos showing sporty 100ms rebalancing downtimes for your stateful Kafka Streams application, no matter the size of the application’s state.
As a bonus accessing Cassandra State Stores via 'Interactive Queries' (e.g. exposing via REST API) is simple and efficient since there's no need for an RPC layer proxying and fanning out requests to all instances of your streams application.

3. We have two method for establish of remote access connection
Remote Access connections:
Dial-up PPP
Broadband TCP/IP
Remote and Dial-up Connections
4. is a form of Internet access that uses the facilities of the public
switched telephone network (PSTN) to establish a dialed connection
to an Internet service provider (ISP) via telephone lines. The user's
computer or router uses an attached modem to encode and decode
Internet Protocol packets and control information into and from
analogue audio frequency signals, respectively.
Dial-up Internet Access
12. Broadband Internet Access
Broadband Internet service truly is the most used form of Internet access
because of its high access speeds; it is offered in four different forms, DSL
(or Digital Subscriber Line), also fiber-optic, cable, and satellite.
The old dial-up connection is the only non-broadband internet service available,
and even though it is cheaper, most Internet users are moving towards the
faster broadband Internet connection.

22. VPN is special type for WAN(Wide Area Network) which achieves to connect
without use leased private lines. It uses to establish Internet.
Development of VPN is to establish secure and cost effective long distance links
between two or more computing networks.
VPN has its own set of software programs, protocols and security constructs
which make secure connectivity possible.
The USP of virtual private computer networks over conventional computer
networks lies in the fact that this technology is a significantly low cost alternative.
VPN (virtual Private Network)
24. 1. Remote client access via VPN
2. Peer to peer VPN (can let two separate local area networks, to be linked
together)
3. Private VPN (private intranet of a company that allows enabling of access
control for each user)
VPN (virtual Private Network)
Types of VPN
25. How VPN Works
Install VPN client programs on the machines which need remote access
Enable Internet connectivity provided by an ISP, after verification of user name
and password.
Access the private network easily use client remote computer.
VPN (virtual Private Network)
26. Benefit of VPN
Substantially easy and inexpensive to set it up
Can provide long distance connectivity, between multiple branches of a company
office, by providing secure data transfer and encryption, to enable video
conferencing, as well as data transfer.
Reduces the costs involved in maintaining long distance networks and costs of
operation.
VPN is a technology that are really cost effectiveness, efficiency and security
features of virtual private networks make them attractive and preferred choices
over conventional leased line based networks. Because of that, most industry
Intranets use VPN technology to establish internal connectivity.
VPN (virtual Private Network)
41. Authentication Protocols
PPP uses two authentication protocols PAP and CHAP.
CHAP is the preferred protocol, because CHAP uses 3-way handshake;
whereas, PAP uses 2-way handshake.
CHAP is an authentication scheme used by Point to Point Protocol (PPP)
servers to validate the identity of remote clients.
CHAP provides better security as compared to Password Authentication
Protocol (PAP). The protocol exists in two versions,
MS-CHAPv1 and MS-CHAPv2
42. Authentication Protocols
PAP : Sends username and password In clear text
SPAP : shiva LAN Rover client encrypts password but not data
Challenge-Handshake Authentication Protocol (CHAP):
encrypt username and password but not data , for non-Microsoft
operating systems
Ms-CHAP1 : one way password encryption
Ms-CHAP2 :mutual authentication , stronger encryption .(NT+98,VPN only)
