A Novel Method for Survivability Test Based on End Nodes in Large Scale Network.
Survivability is a necessary property of network system in disturbed environment. Recovery
ability is a key actor of survivability. This paper concludes network survivability into a novel
composite metric, i.e. Network Recovery Degree (NRD). In order to measure this metric in
quantity, a concept of Source-Destination Pair (SD Pair), is created to abstract end-to-end
activity based on end nodes in network, and the quality of SD Pair is also used to describe
network performance, such as connectivity, quality of service, link degree, and so on. After
that, a Survivability Test method in large scale Network based on SD pairs, called STNSD, is
provided. How to select SD Pairs effectively in large scale network is also provided. We set up
simulation environment to validate the test method in a severe destroy scenario and evaluate
the method scalability in different large scale network scenarios. Experiment and analysis
shows that the metric NRD correctly reflects the effort of different survivability strategy, and
the proposed test method STNSD has good scalability and can be used to test and evaluate
quantitative survivability in large scale network.
