Toward Effective IMS Connectivity over Ipv4-Ipv6 Coexistence Network: Design, Implementation, and Experimental Evaluation

Abstract

IP Multimedia Subsystem (IMS) is a standardized architectural framework for delivering IP multimedia services (voice and video) between end-to-end devices. Session Initiation Protocol (SIP) is still a promising protocol for handling real time communication in IMS. In industry, SIP service providers supply services for millions of end-users concurrently. That can be achieved through a clusters SIP servers under high control level. However, poor management in SIP connectivity considered to be serious issue in SIP infrastructure especially during connections established between two different networks family (IPv4/IPv6). This paper proposed a mechanism called SIP-Cluster IP Family (SIP-CIF) which aims to distribute SIP calls among cluster nodes based on IP family (IPv4/IPv6) to ensure better connectivity. For better performance, the mechanism makes use of NoSQL cache system for fast consultation. Evaluation is achieved by applying high load traffic in two different scenarios. In sum, results have shown that the proposed mechanism performs efficiently compared to IP translation mechanism. In addition, the proposed mechanism insured wised resource utilization after bandwidth and CPU been evaluated.
