Enhancing Performance of Proxy Cache Servers Using Daemon Process

Abstract

The significant increase in Internet users has led to an enormous rise in the network traffic which had a great impact on the characteristics of the network like reduced bandwidth, increased latency and higher response time for users. The most common method used is proxy cache server which is deployed to reduce the web traffic and workload on server. Proxy cache server stores the data locally but there is a problem of stale data. There are many instances when the proxy cache returns the data stored in its cache rather than returning the latest version from the original server. This paper is concerned with a methodology that addresses this issue of stale data by introducing Daemon process. Daemon is a background process that updates the data present in the cache periodically. It does not interfere with the processes of the user and updates the data when minimum number of users is online. Understanding and identifying the main characteristics is crucial part to plan techniques that help us save the bandwidth, improve access latency and response time. This paper focuses on the factors affecting the proxy cache server as well as on Daemon process.
