Problems solved by technology

The disadvantage of this solution is that the forwarding capability of these interface boards cannot be reflected because the interface boards with specifications smaller than the proxy board do not forward, but are all forwarded by the proxy board, and the forwarding capability of the distributed equipment is limited. Forwarding capability of proxy board
[0005] It can be seen that in the two existing methods, the forwarding capability of distributed equipment is limited, and the forwarding function of each single board cannot be fully utilized.

Embodiment 1

[0031] In this embodiment, the main control board proxy mode is adopted, that is, the main control board with the forwarding function is used as the proxy board to provide a three-layer forwarding agent for the interface board that needs the proxy.

[0032] see figure 1 , figure 1 It is a schematic structural diagram of a distributed device applied in Embodiment 1 of the method of the present invention. The device includes 1 main control board and 3 interface boards (interface board 1, interface board 2, and interface board 3), where each board includes a forwarding unit, and the forwarding entry specification of the forwarding unit in a single board is The forwarding entry specification of the board. The size of forwarding entries on the main control board is 128,000, the size of forwarding entries on interface board 1 is 256, the size of forwarding entries on interface board 2 is 12,000, and the size of forwarding entries on interface board 3 is 128,000. In a distributed ...

Embodiment 2

[0041] This embodiment adopts the interface board proxy mode. In this embodiment, the interface board with the largest forwarding entry specification is used as the proxy board to provide three-layer proxy forwarding for the interface boards that need to be proxied.

[0042] see Figure 5 , Figure 5It is a schematic structural diagram of the distributed equipment used in the second embodiment of the method of the present invention. The device includes 1 main control board and 4 interface boards (interface board 1, interface board 2, interface board 3, and interface board 4). 0; each interface board includes a forwarding unit, the specification of forwarding entries of interface board 1 is 256, the specification of forwarding entries of interface board 2 is 12000, the specification of forwarding entries of interface board 3 is 128000, and the specification of forwarding entries of interface board 4 The specification of forwarding entries is 256,000. In addition, the main co...

Abstract

The invention discloses distributed equipment and a three-layered agency retransmission method thereof, wherein the method comprises the following steps: carrying out three-layered retransmission of messages within the range of a retransmission list item specification by an interface board when the retransmission list item specification of the interface board is between the minimum specification and the specification of an agency board; carrying out two-layered retransmission of the messages beyond the range of the retransmission list item specification to the agency board, and carrying out the three-layered retransmission by the agency board. The invention can improve the retransmission capability of the distributed equipment and fully exert the retransmission function of each veneer.

Description

technical field [0001] The invention relates to the technical field of distributed equipment, in particular to a three-layer proxy forwarding method of distributed equipment and distributed equipment. Background technique [0002] The distributed device includes multiple single boards, where the single board may be a main control board or an interface board. The specifications of the forwarding entries of each board are different; the specifications of the forwarding entries reflect the forwarding capability of the board, and the larger the forwarding entries of the board, the stronger the forwarding capability of the board. In order to ensure the consistency of the forwarding capability of the entire distributed device, that is, no matter which single board receives an incoming message, it can be forwarded according to the same capability, the following two implementation schemes are adopted in the prior art. [0003] In the first type, each interface board does not need t...
