Reliable GMPLS control plane

The ASON/GMPLS is considered as the next generation Internet backbone technology. Since the recovery mechanisms are developed to provide high reliability, the reliability of the control plane must be also considered. Therefore, different models of the control plane are discussed. These models offer different level of reliability. The implementation of the model with signaling redundancy is proposed. The availability analysis of newly proposed model is performed. The results confirms high availability of the control plane and thereby the improved availability of overall transmission system.
