Converged OAM

Abstract

Operation, Administration, and Maintenance (OAM) is a toolset that can be used for managing different networking layers. OAM can detect and isolate the faults and also be used for performance monitoring of a network, which helps in reducing the operational cost. OAM mechanism is important for networks that are required to deliver network performance and availability objectives. OAM toolset is defined for different layers in protocol stack. This paper summarizes OAM toolset supported by Ethernet, MPLS, and IP networks. Since many standard bodies are working on enhancement of OAM, it results in multiple OAM standards which are performing the same functionality. Main objective of this paper is to detail scattered OAM toolset of Ethernet,MPLS, and IP networks and to propose a solution forOAM toolset convergence, which can be beneficial for service provider and customer.
