Availability research on protection mechanisms in ASON networking

Gao Huisheng1,Yu Xiaodong1,Guo Jing1,Jin Weiwei2(1.Department of Electronics and Telecommunication Engineering,North China Electric Power University,Baoding 071003,China; 2.HVDC Power Transmission Control and Protection Department of XUJI,Xuchang 461000,China)  
As the demand of the network users for network availability is increasingly higher,to evaluate and quantify network availability has become a major research subject.This paper analyzes the general protection mechanisms for ASON and provides for each of them an algebraic formula for the availability analysis.It verifies the validity of the availability model by calculation examples,analyzes the relationship between the availability of the protection mechanisms and the relevant network parameters and makes comparisons between the availability degrees brought about by various protection mechanisms.
