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。
