MPLS Transport Profile (MPLS-TP) technology is gaining importance as it becomes a dominant solution for a converged transport network in recent years. MPLS-TP ring protection mechanism defined in standards provides the ability to restore traffic delivery following failure or degradation of network resources to meet carrier-class transport network requirements. The article outlines MPLS-TP ring protection...
A testbed based on European Cost-239 topology is constructed to demonstrate the transmission performance of MPLS-TP network. By introducing streaming media traffic, two factors are given with numerical results to show their influences on transmission.
Generalized Multi-Protocol Label Switching (GMPLS) based optical networks are viewed as a promising network infrastructure for the next generation network (NGN) development. By pre-configuring the resources of dynamic optical networks, we can reconstruct the physical topology, thus increase the number of direct routes between potentially heavily loaded physical node pairs and optimize the performance...
Transport MPLS (T-MPLS) is regarded as one of the most important transport technologies in the next generation network (NGN). It is a connection-oriented packet transport technology that developed from MPLS techniques and now defined by ITU-T SG13 & SG15. In this paper, we analyze the architecture of the T-MPLS networks. Also the most important building blocks for the modular design of the common...
Transport multiple protocol label switching (transport-MPLS, T-MPLS) is one of networking schemes for packet transport network (PTN). It specifies a connection-oriented, packet-switched architecture for carrier class Ethernet. In order to evaluate the performance of T-MPLS network, we have to apply this technology to the real network topology with Internet-bound traffic (e.g., VoIP, P2P, Http). In...
As most of the carriers have extended their circuit transport networks with packet transport capabilities due to the inefficient transport network architecture, the controlling manner developed silently. Multiple service transport platform is the newly proposed packet based transport technology and the standardization process is very fast. GMPLS is considered to be the future controlling technologies...
