Fuzzy CAC Adaptation for Effective Traffic Control in GMPLS Networks

Current paper presents the report of some issues on adaptation techniques of the specific implementation of fuzzy-CAC algorithm over an RSVP-TE agent that can be used in GMPLS network domain. The algorithm is used to provide stable link utilization and achieve preferable rate of rejected LSP connections, while maintaining selective reasoning under uncertain conditions. Fuzzy-CAC implementation is applied to a testbed where a client application requests a real-time data transfer through a GMPLS network, which results in dynamic LSP setup and exclusion. Adaptation to the continuously changing environment is achieved by the modifications to the membership function declarations and fuzzy-CAC interface decision firing threshold for deffuzified response values
