Abstract: A signal processing method and device of multi-protocol switching network are provided, which belong to the field of network communication. The method enables time division multiplexed (TDM) frames to be transmitted in a form of sub cell information through de-interleaving and slicing processes of the TDM frames. The method and device can switch TDM frames and packets uniformly with a flexible processing manner and low cost, so as to better support the network to evolve from TDM to All IP.

Abstract: Embodiments of the present invention provide a method and a node for discovering topology structure automatically in a Multi Protocol Label Switching (MPLS) ring network. The method includes: when receiving a topology discovering message, determining, by a node in the MPLS ring network, whether the topology discovering message is sent by the node; if yes, updating information of topology structure of the MPLS ring network stored in the node according to information of topology structure of the MPLS ring network carried by the topology discovering message; otherwise, appending information of topology structure of the node to the topology discovering message and forwarding the topology discovering message to a next node. Thus, the network topology may not depend on the topology of the physical layer network and the speed of discovering topology structure of the ring network is increased.

Abstract: A communication apparatus, a method and a switch board for universal switching of multiple services. The communication apparatus includes a backplane board, a switch board, and a plurality of service boards. The switch board and the service boards are inserted into a switch board slot and a plurality of service board slots on the backplane board respectively. Only one set of service buses is provided on the backplane board. The switch board includes a plurality of switching modules associated with the services and adapted to schedule and switch the services. The communication apparatus further includes a selector adapted to connect the service buses to respective switching modules associated with the services according to types of the services. The method includes: connecting, by a selector, service buses with respective switching modules associated with the services according to types of the services; scheduling and switching the services by the switching modules.

Abstract: This invention discloses a ring network and a method for implementing the service thereof. The ring network includes multiple nodes in a same logic layer for accessing a service to the ring network or receiving a service from the ring network; two virtual channels of reverse directions, which connect the adjacent nodes and are utilized to bear and adapt service data; a physical link, which is utilized to bear the service data adapted to the virtual channel.
