¿µ¹®³»¿ë¿ä¾à The standard describes an overview of generic aspects of a shared mesh protection (SMP) mechanism for connection-oriented layer networks that does not depend upon the presence of a control plane. SMP provides a method for sharing resources in the mesh network for protection against one or more failures in the network. This mechanism is targeted for mesh network architectures, which offer further efficiencies in protection resource utilization. The primary characteristics of this path-based protection approach involve usage of pre-computation and pre-allocation of resources to maximize speed of recovery.
