Abstract:

The establishment of a reasonable model to evaluate and quantify the elasticity offers great help in future forecast and decision.In this paper,a number of service attribute indexes are sett,the corresponding performance score calculated introduced,and the adaptive score and the service state of a single service given based on a set of performance scores.And finally combined with the Markov network model and elastic function equations,the whole network resilience is evaluated.This paper considers not only the single service condition,but also the mutual dependencies between services.It is of referential value in the future network elasticity measurement,fast search for fault,and state threshold setting.

Key words: network elasticity;reliability evaluation;quantitative model
