PROTECTION MECHANISM WITH DIFFERENTIATED SERVICE RELIABILITY IN MULTI-DOMAIN OPTICAL NETWORKS BASED ON CONDITIONAL RISK DISJUNCTION DEGREE

摘要：

In order to improve survivability of Multi-Domain Optical Network (MDON) and differentiate service reliability, this paper provides a Protection mechanism with Differentiated Service Reliability in MDON based on Conditional Risk Disjunction Degree (CRDD), called PDRC. Firstly, defines CRDD, provides Intra-domain virtual links Reflection arithmetic based on CRDD considering wavelength Continuity (IRCC) to form aggregation topology, then provides Arithmetic of Computing work route and backup route with Differentiated service reliability based on CRDD (ACDC) to compute work route and backup route in aggregation topology. The results verify that the proposed protection mechanism not only differentiate service reliability, but also reduce blocking rate of service and improve usability of network.
