Title:
通信ネットワークにおける修復保護
Document Type and Number:
Japanese Patent JP2004531959
Kind Code:
A
Abstract:
Restoration of a failed link on a network is achieved by reserving a portion of the transmission bandwidth for at least some of the links connecting nodes of the network. The reserved portion of the transmission bandwidth is used for the transmission of traffic diverted from a failed link to provide a restoration path for that diverted traffic thereby enabling a protection path to be determined dynamically. The reserved portion is preferably configured in a block so that contiguous concatenated payloads can be transmitted across the protection bandwidth.
