Survey on NMS Supporting Network Elements implementing Heterogeneous Protocols

In the telecommunication, mediation is the process in which network elements and element managers will get integrated with Operations Support system. Mediation involves conversion of protocol, model of mapping information. Mediation is an essential process in today-s heterogeneous telecommunication domain. Network Elements such as routers, servers and switches communicate through a wide range of protocols (SNMP) and information models (CORBA). The information models and protocols used by Network Element depends on the manufactures choice and the type of Network Element. The diversity which is found in Network Element is also found in Operation Support Systems to support NEs. OSS-s are used by service providers to monitor the NEs that comprise a network. OSS is a platform that has been designed to manage a set of NEs using a specific protocol type and information model. As network size increases, the probability of a network remaining homogeneous with respect to the protocol used by its NEs and OSS decreases. For large and diverse networks, it will be difficult to maintain one OSS for each protocol. In this article A network management system with protocol converter is used in order to reconcile the differences between the chosen OSS protocol and the Network Elements it manages
