Embodiment Construction

[0037] The present invention aims to provide a distributed communication device and an inter-board communication method, which solves the problems of poor scalability of traditional solutions, limited number of line cards supported by multicast, and complex multicast settings for switching chips required for inter-board communication.

[0038] Such as figure 1 As shown, the distributed communication equipment in this embodiment includes:

[0039] A main control card, an Ethernet switch chip, and multiple line cards; the main control card and the multiple line cards are all connected to the Ethernet switch chip;

[0040] The Ethernet switch chip is used to send the message to the main control card or a corresponding line card according to the destination MAC address of the received message;

[0041] When the main control card is used to construct the Ethernet message sent to the destination line card, the bitmaps of all line cards are stored in the Ethernet message, and each b...

Abstract

The invention relates to the technology of data communication, discloses an inter-board communication method for a distributed communication device and solves the problem that a traditional scheme is low in expansibility, the number of line cards supported by multicast is limited, and complex multicast setting needs to be carried out on a switching chip when inter-board communication is carried out. The method comprises the steps of a, when a main control card establishes an Ethernet message sent to a destination line card, developing a field for storing bitmaps of all line cards in a self-defining field of the message, wherein each bit in the bitmaps and each slot of each line card are in one to one correspondence, and the master control card sets a state value of the bit corresponding to the slot of each line card in the bitmaps; the Ethernet switching chip receives the message from the main control card and then sends the message to the corresponding destination line card according to a destination MAC address in the message; and c, the destination line card receives the message forwarded by the Ethernet switching chip and then decides whether to discard the message or not according to the state value of the slot corresponding to the slot of the line card in the bit map. The invention also discloses the distributed communication device.

Description

technical field [0001] The invention relates to data communication technology, in particular to a distributed communication device and an inter-board communication method. Background technique [0002] Distributed communication equipment generally consists of a main control card and a service line card. A large amount of information interaction is required between the main control card and the service board, including: the information sent by the main control card to the service line card, such as protocol messages, various configuration information, etc., and the information sent by the service line card to the main control card Such as protocol messages, alarm messages, etc. [0003] The most widely used connection method between each board is to connect each board through the port of the Ethernet switch chip, and a board is connected to at least one switch port. In some cases, the main control card needs to send the same information to multiple line cards, such as sendi...
