DISTRIBUTED LOCATION BASED PROXY ARCHITECTURE FOR VIDEO LEARNING PORTAL USING WEB PROGRAMMING TECHNOLOGIES

Abstract

This project describes architecture for making media on demand services for e-learning portals as efficient as possible by making use of distributed proxy servers. The proxy servers may be kept at different locations and the databases which they access can also be distributed on different locations or different machines. The specialty of this architecture is that it uses the location of the client demanding the media as a major factor in determining which proxy server will respond to the request. This job is done by the Proxy determining logic which is a unique server for the whole architecture and which plays a central role in the functioning of the same. All the proxy servers use caching techniques and there is a central Backup server that ensures service continuity in case the main server fails due to any reason like power cut. The idea behind keeping the proxy determining logic and the location based proxy servers is that the proxy server nearest to the client will not only be having the shortest route to the client but also the chances of interruption of the service will be low. Due to lower physical distance the number of routers and gateways between the Thus the whole architecture ensures that the client gets his video/audio as smoothly, as quickly and using as low net bandwidth as possible.
