With the rapid growth of the Internet, it leads to insufficiency of the bandwidth and congestion. In order to solve these problems, IP connectionless services over ATM networks would be preferably solution. MPLS is a high-performance method for forwarding packets. It integrates Layer-2（Data Link Layer） with the scalability and flexibility of Layer-3（Network Layer） routing. It is applicable to networks using any Layer 2 switching. Therefore, it is a kind of technology for integrated transport of IP-over-ATM networks. An MPLS network is composed of many Label Switch Routers (LSR). A LSR works as a router, and may execute LDP which is to replace the complex ATM signaling protocol. Whenever an interior LSR receives an IP packet, it forwards this packet based on the "Label" instead of the IP header. As a result, MPLS technology can make the operation more efficient. This thesis gives a study of the MPLS technology and application for ATM networks: including protocol, transfer operation of IP packet, tester emulation and its result analysis, and providing the applications of high speed networks.
