Embodiment Construction

[0024] Aiming at the problem that in the routing forwarding implementation process in the prior art, when master / standby switchover is required, the routing forwarding and management control functions need to be switched at the same time, thus both of them will be interrupted, resulting in a relatively long recovery time. The embodiment of this application provides a A device for implementing routing and forwarding is used to solve the above problems. The structure of the device is as figure 2 As shown, it includes: the main control board 10, the backup control board 11, the main forwarding board 20, the standby forwarding board 21 and several service boards (such as: service board 1, service board 2, ..., service board N, etc.). The active forwarding board 20 and the standby forwarding board 21 forward data for service boards, and the active control board 10 and the standby control board 11 control the data forwarding of the active forwarding board and the standby forwardin...

Abstract

The invention discloses a route retransmission realization device and method, and switching equipment. The device comprises a plurality of service boards, a primary retransmission board, a standby retransmission board, a primary control board and a standby control board, wherein the standby control board is used for starting the primary-standby switching when detecting a failure of the primary control board, and establishing an information channel between the standby control board and the primary retransmission board or standby retransmission board; and the primary control board or standby control board is used for starting the primary-standby switching when detecting a failure of the primary control board, establishing an information channel between the primary control board or standby control board and the standby retransmission board, and establishing an information channel between the standby retransmission board and the service boards, thereby realizing data message interactions between the standby retransmission board and the service boards. When the primary control board fails, the retransmission service of the device can not be interrupted. When the primary retransmission board fails, the service boards are simple and quick to switch, thereby shortening the service interruption time, increasing the service restoration speed and reducing the time delay.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a routing and forwarding implementation device, method and switching equipment for improving the reliability of routing equipment. Background technique [0002] Routing generally refers to the act of moving information (data packets) from a source location to a destination location through an interconnected network. During the routing process, information will pass through at least one or more intermediate nodes. Data routing is different from data exchange. Data exchange occurs at the second layer of the OSI reference model (ie, the data link layer), while data routing occurs at the third layer (ie, the network layer), so the two are used in the process of moving information. Different control information is implemented in different ways. [0003] Routers used for data routing can be divided into centralized routers and distributed routers according to different implemen...
