Abstract

This invention relates to multiple protective band dynamic adjusting method, which comprises the following steps: the web tube sends protective and business dispatching information network host machine, wherein the information comprises protective device module needed channel information; the said protective matching module sends the information to the said net element pressure formula module and automatic updating the business adjust and pressed list; the list protection module sends to the said net element automatic protection inverse agreement module and the formula module sends pressed list to protect inverse agreement module to switch to the said new element crossing formula to process virtual recovering for virtual inverse.

Description

technical field [0001] The invention relates to a method for adjusting the bandwidth of a multiplex section protection ring in an optical network, in particular to a method for dynamically adjusting the bandwidth of a multiplex section protection ring in an optical network. Background technique [0002] Modern society relies more and more on communication. The failure of important communication will lead to serious loss or even catastrophic consequences. The survivability of communication network, that is, the timely recovery of the faulty network, is very important. The self-healing network is a concept to improve the survivability of the network. For the self-healing network, without human intervention, the network can automatically restore the services carried by the failure in a very short period of time, so that users do not feel The network has failed. [0003] Multiplex section ring protection is a way to realize the self-healing network. The multiplex section ring p...
