Survey on Traffic Redundancy and Elimination Approach for Reducing Cloud Bandwidth and Costs

Abstract

Cloud computing is a fast growing field which is arguably a new computing paradigm. In cloud computing, computing resources are provided as services over the internet and users can access resources on based on their payments. Transmission cost plays an important role when trying to minimize cloud cost. However for server specific TRE approach it is difficult to handle the traffic efficiently and it doesn’t suites for the cloud environment because of high processing costs. In this paper we give a survey on the new traffic redundancy technique known as novel-TRE also known as receiver based TRE. This novel-TRE has significant features like detecting the redundancy at the client, repeats appear in chains, matches incoming chunks with a previously received chunk chain or local file and sending to the server for predicting the future data and no need of server to continuously maintain client state.
