ACTIVE-FAULT-ALARM BASED DYNAMIC TEMPORARY PROTECTION MECHANISM FOR MPLS-TP OPTICAL NETWORKS

摘要：

This article proposes an Active-Fault-Alarm (AFA) based Dynamic Temporary Protection Mechanism (DTPM) that is applied into the multi-protocol label switching transport profile (MPLS-TP) optical network. The new DTPM, by using the AFA function, can establish dynamically the so called temporary protection path (TPP) for the work path in advance before possible fault occurs and keep flexibly the TPP only during the lowquality or fault period of the work path. Therefore, the novel DTPM is greatly different from the 1:1 Traditional Linear Protection Mechanism (TLPM). Experimental results show that the DTPM has better performance in terms of flexibility and efficiency.
