【摘要】 自动交换光网络(ASON)是一种能够自动完成网络连接的新型网络。控制面技术是其核心,一些协议(如GMPLS)正在逐步应用到ASON控制面中。网络生存性是指网络发生故障时提供连续业务的能力。基于GMPLS的网络生存性技术对于网络的运营具有重要的意义。本文介绍了光网络的生存性技术并结合GMPLS与ASON控制平面对光网络的生存性进行了较为深入的研究。更多还原

【Abstract】 Automatic Switched Optical Network(ASON) is a new type of network which can accomplish network connection automatically.Control plane is the core technology.Some protocols,such as GMPLS,are gradually applied in the ASON control plane.Network survivability is the ability that network can provide continuously services when a fail occur.GMPLS-based network survivability has a significant meaning to the operation of network. This paper introduces the network survivability and study the network survivability integrates with the technology of GMPLS and ASON control plane.更多还原
