TDM have been got the better profitability for a long time. The PWE3 provides a method for retaining this high return service, at the same time migrating TDM towards IP/MPLS packet transport network. Transport MPLS is the most promising technology for packet transport network. In this paper, the architecture and key technology of pseudo wires emulation edge to edge for TDM over transport MPLS is introduced...
Increases in network traffic due to the expansion of IP broadcast services in recent years have stimulated the requirement of performance and capability in transport network. As an attractive candidate to support the packet switching functionality envisioned in converged next generation transport systems, T-MPLS is gained more attentions to find out its characteristics. This paper describes a T-MPLS...
An improved scheme of path selection for multi-layer network based on PCE and VNTM is present and evaluated on the simulation platform of NSFNET, which is used to avoid traffic redundancy caused by low layer's invisibility to the high layer.
