NETWORKING PORTABILITY THROUGH VPN
What is VPN?
Virtual Private Network is a network that is constructed by using public wires to connect nodes. For example, there are a number of systems that enable you to create networks using the Internet as the medium for transporting data. These systems use encryption and other security mechanisms to ensure that only authorize users can access the network and that the data cannot be intercepted.

In the present scenario when Telephony systems are moving to a common wiring plant the end station of a LAN or IP- based PBX must be simple to use, familiar and relatively cheap. While the H.323 recommendations are pretty expensive, an H.323 proxy can be used to communicate with the Skinny Client using the SCCP. Here the telephone is a skinny client over IP, in the context of H.323. A proxy is used for the H.225 and H.245 signaling. Skinny messages are carried above TCP and use the port 2000 at the same time the skinny client (i.e. an Eth ....etc

ABSTRACT
Virtual Private Networks is a concept introduced to implement global Wide Area Network(WAN) on the Internet. This way enormous costs involved in the traditional implementation of these networks i.e. through dedicated lines or satellite links is reduced considerably. A way to maintain fast, secure and reliable communications is attained wherever the offices are.

In the VPN, Internet is used as the data pipelined replacing the traditional datalines. This approach is just right for small and medium sized busines ....etc

The secure connection consists of two types , either an individual computer or a LAN with a security gateway.
The LAN-to-LAN connection , where a security gateway is end with an IP address

Client Server Software Engineering

Abstract :

The term client/server was first used in the 1980s in reference to personal computers (PCs) on a network. The actual client/server model started gaining acceptance in the late 1980s. The client/server software architecture is a versatile, message-based and modular infrastructure that is intended to improve usability, flexibility, interoperability, and scalability as compared to centralized, mainframe, time sharing computing.

A client is defined as a requester of services and a server is d ....etc
