Problems solved by technology
[0004] The disadvantage of the existing technology is that: during the master-standby switchover process, the service uplink is switched from the No. 1 main control board to the uplink board to the No. 2 main control board to the uplink board. During this process, there will be a large data loss. Uplink services are interrupted, resulting in slow master / standby switchover

Embodiment Construction
[0022] The core of the present invention lies in: adding a multi-way connection device for connecting the upper connection boards to the plurality of main control boards, and the upper connection board sends the same message to the main control board through the multi-way connection device. Downlink data; add a logic device to determine whether it is in the active state or the standby state according to the respective state signals sent by the main control board, and control the multi-way connection device to send to the main control board in the active state receive uplink data.
[0023] The switching device proposed by the present invention will be described below with an embodiment, as figure 1 As shown, the switching device includes: an uplink board 1, an active main control board 2, a standby main control board 3, a multi-channel connection device 4 and a logic device 5;
[0024] The multi-channel connection device 4 is used to connect the uplink board 1 to the main main...

The invention discloses a device and a method for rapid active-standby switching in network equipment. The device comprises an upper connecting plate, a plurality of main control boards, a multi-channel connecting device and a logic device; the multi-channel connecting device is used for connecting the upper connecting plate to the plurality of main control boards respectively; the upper connecting plate sends the same downlink data to the main control boards through the multi-channel connecting device; and the logic device is used for judging whether the main control boards are in an active state or in a standby state according to respective state signals sent by the main control boards, and controlling the multi-channel connecting device to receive uplink data sent by the main control boards which are in the active state. In the invention, a method of copying the data by hardware makes the upper connecting plate simultaneously send the data to the active-standby main control boards, but only receive the data of the active main control boards; and when the active-standby switching occurs, the upper connecting plate can be immediately switched to the main control boards changed into the active state from the standby state to receive the data so as to furthest reduce the loss of service traffic and improve the speed of the active-standby switching.
Description
technical field [0001] The invention relates to the active-standby switching technology in communication equipment, in particular to a method and device for fast active-standby switching of network equipment in the communication field. Background technique [0002] In communication equipment, in order to improve the reliability of the equipment, the main control board often adopts the active and standby mechanism. The upper board is relatively simple and not easy to damage, and generally does not use the active and standby mechanism. When the main main control board, which can also be referred to as the main control board in active state (for example, denoted as No. 1 main control board), fails, the service control and service forwarding are switched to the standby main The main control board in the standby state (for example, it is recorded as No. 2 main control board), and the state of the standby main control board becomes the active main control board, and the state of ...
