Embodiment Construction

[0031] see figure 2 , figure 2 A structural diagram of the dual-master switching device provided by the technical solution of the present invention. The dual main control board switching device includes two main control boards and at least one line card. Wherein, the main control board includes a processing unit and a switching unit. The switching unit is connected to the processing unit of the board through the channel port, and is used to receive the message sent by the processing unit of the board and forward the message to the processing unit of the board; the switching unit is connected to the switching unit of the opposite main control board through the connection port Connected, used to receive the message sent by the peer switch unit and forward the message to the peer switch unit; the switch unit is connected to the line card through the line card port, used to receive the message sent by the line card and forward it to the line card message. Here, it should be ...

Abstract

The invention discloses double main control exchange equipment and a method and a device for issuing forwarding table, wherein, the double main control exchange equipment provided by the invention solves the problem of limited hardware resources of the prior double main control exchange equipment through arrangement of exchange units with the exchange function in a main control panel. Moreover, the method and the device for issuing forwarding table provided by the invention realize the forwarding function of the exchange units by forwarding table used for unicast communication and forwarding table used for multicast communication to the exchange units in the main control panel. The method and the device for issuing forwarding table provided by the invention aiming at multicast communication can prevent multicast vibration between two exchange units and are favorable for realizing multicast communication between main control panels.

Description

technical field [0001] The invention relates to data communication technology, in particular to a dual-master switching device, a method and a device for delivering forwarding entries. Background technique [0002] see figure 1 , figure 1 Shown is a structural diagram of an existing dual-master switching device using a switching chip to realize inter-board interconnection. In this implementation solution, the main control board realizes the communication between the main control boards and the communication between the main control board and the line card by using its Layer 2 forwarding function through the switch chip. [0003] From figure 1 It is not difficult to see that in the existing dual-master switch equipment, the switch chip exists independently of the main control board 1, the main control board 2 and the line cards. In this way, in hardware implementation, the switching chip needs to independently occupy hardware resources in the switching device, such as slo...
