摘要
SIP作为NGN和软交换技术的一个重要发展方向已成为日前研究和应用的热点,针对SIP应用的特定需求,研究移动自组网的防护、检测、响应和恢复的综合保障方案,利用基于信誉机制的动态安全防护体系和主动冗余技术,确保在提供SIP服务的某些节点失效后整个系统仍然能够正常工作,提高网络抗毁和生存能力,保障SIP应用的可靠性、抗毁性、健壮性和高可用性.
As an important direction of NGN and soft-exchange research,SIP has become the hotspot in recent research anu practice. The research aims at the special demand of the practice of SIP,studing the safeguard scheme of protection,detection, response,and reservation. It takes advantage of the dynamic protection system and active redundancy technique in the mechanism of reputation to ensure the system to work well when the nodes that present SIP service are in trouble. So it can make the network more robust and ensure the usage of SIP more reliable ,more resistant to smash ,more robust and more usable.
