Improving Performance Among Client-Server For Continuous Distributed Interactive Applications
Journal Title: International Journal of Research in Computer and Communication Technology - Year 2015, Vol 4, Issue 9
Abstract
In today’s situation consumers mainly use the network as an interactive medium for multimedia entertainment and communication purpose. In the entertainment arena, new applications involve multiple users participating in a single interactive session, for example, online gaming. In distributed server architecture, the interactivity performance depends on not only client-to-server network latencies but also interserver network latencies. All of these factors are directly affected by how the clients are assigned to the servers. We propose a Latency EQualization (LEQ) service, which equalizes the perceived latency for all clients participating in an interactive network application. We achieve equalized-latency paths by using a few routers in the network as hubs, and interactive application packets from different clients are redirected through these hubs to the servers. We formulate the hub placement problem, and provide the greedy algorithm and the optimal algorithm to solve this problem. Through extensive simulations, we show that our LEQ hub routing architecture significantly reduces delay difference in large network topologies. The LEQ architecture is incrementally deployable in today’s networks, requiring only a few nodes to be modified to perform the LEQ service.
