Peer-to-Peer File Sharing Across Private Networks Using Proxy Servers


The Internet today is commonly used as a medium to share large size multimedia content. This sharing is carried out, a number of times, through the Peer to Peer sharing architecture rather than the conventional server-client model. The paucity of network addresses in the Internet has led to the emergence of private and global networks. Because the identity of peers in a private network remains hidden behind their global endpoint, P2P applications cannot run betwee ....etc

Development of a HTTP Caching Proxy Server

A proxy acts as an intermediary agent between its clients and the servers which they want to access, performing functions directed towards a variety of purposes, like security, caching, etc, in its capacity as an intermediary. Specifically, caching HTTP Proxy Servers are intermediate servers, which maintain a cache of Internet objects like html files, image files, etc which are obtained via HTTP.

-Intelligent prefetchmg helps to reduce the
perceived delay for document downloading at the user's
end. A monitor agent predicts possible future requests that

independent cache is provided for all users at the proxy
server side. The documents are prefetc ....etc

Cloud Servers vs. VPS (Virtual Private Servers)



VPS Scalability


With traditional VPSs your scalability is directly impacted by the amount of resources used up on the node you currently reside on. If you have a VPS that has 8GB of RAM and you want to scale to 32GB of RAM, chances are you will not be able to do so due to the limitations of the server you are currently on. All your data is stored locally on a VPS so moving you to a new node will not only c ....etc

Proxy Firewall

The Proxy Firewall is developed, keeping the idea of extensive use of extensive use of Internet by institutions and companies in mind.

In computer networks, a proxy server is a server (a computer system or an application program) which services the requests of its clients by forwarding requests to other servers. A client connects to the proxy server, requesting some service, such as a file, connection, web page, or other resource, available from a different server. The proxy server provides the resource by connecting to the specified server and requesting the service on behalf of the client. A proxy server may optionally alter the client's request or the server's response, an ....etc
