Design and Implementation of Locally Distributed Web Server Systems using Load Balancer
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 3, Issue 2
Abstract
This Paper presents the design, implementation and evaluation of a load balancer for cluster-based SIP servers. Our load balancer performs session-aware request assignment to ensure that SIP transactions are routed to the proper back-end node that contains the appropriate session state. We presented three novel algorithms: CJSQ, TJSQ, and TLWL. The TLWL algorithms result in the best performance, both in terms of response time and throughput, followed by TJSQ.TJSQ has the advantage that no knowledge is needed of relative overheads of different transaction types.SIP applications that require good quality of service, these dramatically lower response times are significant. We showed that these algorithms provide significantly better response time by distributing requests across the cluster more evenly, thus minimizing occupancy and the corresponding amount of time a particular request waits behind others for service. TLWL-1.75 provides 25% better throughput than a standard hashbased algorithm and 14% better throughput than a dynamic round-robin algorithm..
