Performance Metric of Convergence Time of Information Flooding in Multi- Area GMPLS Networks
To keep the information of topology and links resource synchronized at each control node, massive messages are necessary to be flooded in the control plane of General Multi-Protocol Label Switching (GMPLS) based multi-area networks. The convergence time of link state based routing protocols will have a significant impact on the performance of the networks. So measuring and analyzing the convergence time of information flooding in multi-areas becomes very important. This document provides suggestions for measuring OSPF multi-area control plane convergence. A performance metric of convergence time of information flooding is proposed to characterize the ability of information synchronization in multi-area networks.
