随着VoIP应用得越来越广泛,其安全问题已成为当前研究的热点.本文以SIP为例,从管理层面出发,提出了SIP网络的监听控管系统.该系统充分考虑了SIP、SIP会话体系结构及SIP网络的安全现状,具有层次化设计、集中化管理和分布式控制相结合、动态智能响应的特点,并具有处理Gbit/s流量,同时检测6 000路SIP会话,根据会话分析进行控管操作的能力.该系统可有效地提高SIP网络的可控性和可管理性.
With the VoIP applied widely, the security problems have become the focus of research. This paper proposes monitoring and control system based on SIP from manage place. This system deeply considers the SIP, the structure of SIP session and security actuality of SIP network. It is designed in hierarchical pattern, with center management and distributed control, and is able to auto-respond intelligently. It also can deal with (;biffs flux, check 6 000 sessions and control with result of analysis. This system can improve the controllability of SIP network effectively.
