Simulation And Analysis On OAM Of T-MPLS

As the amount and type of the transportation services are increasing gradually, the transportation network based on circuit switching is failing to meet the requirements of transporting multiple services efficiently. So the study of the Next Generation Network proposes a trend of merging different layers of the network. T-MPLS is a combination of MPLS and traditional transportation network technologies such as SDH, which is a new application of MPLS on transportation networks.T-MPLS is a connection-oriented technology based on MPLS that provides a general multiple service solution for the next generation transportation network. The unnecessary IP oriented operations are canceled, which will significantly reduce the cost of the service providers. Meanwhile, the capability of multiple service extension supports different kinds of signals (packet, cell, TDM), which matches the trend of network reforming. Compared with the traditional transportation networks, the connection-oriented feature and powerful OAM functions can guarantee the quality requirements of transportation level.Based on the trend of transportation networks developing, this paper analyzed the relation and difference between MPLS and T-MPLS. T-MPLS will adapt the development of transportation networks. Then the concerning standards of T-MPLS are discussed; the architecture and interface of its network were discussed, mainly focusing on the features of OAM. By studying the concerning documents, the algorithms to implement the functions in the simulation are put forward. After the simulation platform is built, these functions are validated and analyzed accordingly.At the end of this thesis, the prospect of T-MPLS technology and its future study fields are foreseen.
