【计】多协议主干网

Packet Transport Network ( PTN) technology includes the Transport Multi-Protocol Label Switching ( T-MPLS) and Provider Backbone Transmission ( PBT).
分组传送网（PTN）技术包括传送多协议标签交换（T-MPLS）和运营商骨干传送（PBT）。
While the technology of Multi-protocol Label Switching ( MPLS) owns excellent network performance and the network configuration mode of ATM is adopted by most of current backbone network, it is of great significance to use ATM in MPLS domain.
MPLS技术具有优良的网络性能，而ATM的组网方式又被目前大多数主干网所采用。研究如何把ATM交换机融入到MPLS域中，是个具有实际意义的研究课题。
With the Multi-protocol Label Switching ( MPLS) technology highly applied and promoted in next-generation backbone network, many higher requirements are proposed to the operation and maintenance of the MPLS network.
随着多协议标签交换（MPLS：Multi-protocolLabelSwitching）技术在新一代骨干网络中的应用推广，对MPLS网络的运行维护提出了更高的要求。
