摘要：

This paper proposes self-healing network techniques suitable for ATM networks in order to realize a high-reliable B-ISDN. First, the characteristics of virtual paths (VP) and their influence on failure restoration are discussed. A high-speed restoration technique which exploits the benefits of VP's is then proposed and described. The technique simplifies the message transmission processes and reduces the number of generated messages by using preassigned backup virtual paths. Next, the scheme used to design the backup VP routes and spare resource distribution for each link is proposed in order to create a network that applies the proposed restoration scheme. Next, self-reconstruction techniques of backup virtual paths are proposed for the realization of a reversionless restoration cycle. Finally, the feasibility of distributed control operation is discussed.
