| 摘 要： | 基于流量工程扩展的资源预留协议(RSVP-TE)作为自动交换光网络(ASON)中最重要的信令协议之一被广泛应用.RSVP-TE的可靠性和生存性机制直接影响到ASON的可靠性.文章具体分析了RSVP-TE的可靠性机制和支撑RSVP-TE生存性的软状态机制,阐述了影响生存性的两种基本故障类型--控制信道失效和平面节点失效,并深入研究了它们相应的恢复机制.

| Abstract: | As one of the most important signaling protocols in ASON,RSVP-TE is widely used.Its reliability and survivability have a direct impact on the reliability of ASON.In this paper,the reliability mechanism of RSVP-TE and the "Soft-Refresh" mechanism in support of RSVP-TE survivability are specifically analyzed,two types of basic failures,signaling channel failure and control plane node failure,that affect signaling survivability described and their appropriate recovery mechanisms studied in depth. |
