摘要：
Development, testing and deployment of routing and signaling protocols for automatically switched optical networks (ASON) are considerably simplified by using an emulation tool. In this paper we present an emulator that supports OSPF routing and (G)MPLS based signaling. Currently the emulator supports the signaling protocol CR-LDP but we are working on the integration of RSVP-TE. Running complete protocol stacks for each emulated node enables the emulator to fill the gap between a network simulation and a real network. To allow the emulation of very large networks which can not be done on a single workstation the network can be emulated using a set of workstation. By adding additional workstations the number of emulated nodes is almost unlimited. The architecture and the functionality of the emulator are described and an example of an emulation is given. The example network with 16 nodes is investigated regarding the behavior in case of network failures.
