REVIEW ON TLS OR SSL SESSION SHARING BASED WEB CLUSTER LOAD BALANCING

Dipesh Gupta, Hardeep Singh

Abstract: Internet users increase the traffic on the servers and server security is the major concern with which the user’s privacy needs to be protect. TLS (Transport Layer Security) is a widely deployed protocol that establishes a secure channel between communicating parties over the internet. But TLS/SSL has huge impact on webserver’s performance by degrading it to a considerable amount. When TLS/SSL session is generated it is broadcasted to all servers in the cluster with which session reuse can be used to save time in negotiation. TLS Handshake and Session resume is occur at the server end so in future if client requests again and its session is not expired then it can again joins that its own session without renegotiating which saves the session initialization time. Ultimately a new load balancing cluster design is proposed that can share TLS sessions in the cluster to effectively improve the performance of TLS web cluster. The web cluster server shares the sessions of users within the cluster. The another technique for improving the latency and throughput of the server SSL/TLS with backend forwarding technique is compare and is analyzed. The traditional method has flaws in the load balancing of the server but with the new implanted technique on the server improves the performance during the high load .The results are reviewed with 16 and 32 node cluster system. With new technique the latency of system has been decreased by the 40 % and throughput of the system is extremely better than classical balancing technique.
