Accelerating Call Route Query of Multi-domain SIP System via P2P
Jing Gong, Qingguo Shen, Huan-Sheng Shen · 2016
Large IP Telephone system may contain multiple domains, and the delay of DNS query across domains may be large.In this paper, the efficiency of call routing in multi-domain SIP system is improved by employing P2P technology.The P2P-SIP system architecture is designed and a no-worse-than-two-hop query algorithm is presented.The formulas for evaluating the performance of the proposed solution are derived.The efficiency of call routing process can be effectively enhanced, and the instability in the system operation can be avoided.The proposed solution can be applied to national wide enterprises or organizations.
