Embodiment Construction

[0044] The present invention provides a system for realizing network port switching, including the main board and the opposite board. Both the main board and the opposite board respectively include a main port and a standby port. The board communicates with the outside world. When the above-mentioned main board is the active board, the opposite board is the standby board; control board; or this board is the backup main control board, and the other board is the main main control board; this board is the main service board, and the other board is the backup service board; . Among them, the media access control MAC layer and the physical layer in the standby port of the board include the first switch of the board, and the switch of the first board is used to select the MAC layer in the backup port of the board to communicate with the board through the high-speed serial bus. The physical layer connection in the standby port, or the physical layer connection with the main port of...

Abstract

The system comprises a local switch board and an opposite switch board, each respectively comprising main port and standby port. In the standby port of local switch board, a first local switch board diverter switch sits between the MAC layer and the physical layer and is used for connecting the MAC layer in the standby port of local switch board to the physical layer in the standby port through high-rate serial bus, or connecting the MAC layer in the standby port in local switch board to the physical layer in the main port of the opposite switch board through high-speed serial bus; in the standby port of the opposite switch board, a first opposite switch board diverter switch sits between the MAC layer and the physical layer and is used for connecting the MAC layer in the standby port of opposite switch board to the physical layer in the stand port of the opposite switch board through high-rate serial bus, or connecting the MAC layer in the standby port of opposite switch board to the physical layer in the main port of the local switch board.

Description

technical field [0001] The invention relates to the technical field of electronic communication, in particular to a method, system and single board for realizing network port switching. Background technique [0002] The router undertakes functions such as forwarding of IP (Internet Pocotol, Internet Protocol) data packets and selection of transmission paths in the Internet. In a centralized router, the main control board is responsible for all transaction processing, including route collection, forwarding processing, device management, etc. After the service board receives the message, it uploads it to the main control board, and after the main control board completes all processing, it transmits it from the target service board. In order to ensure the reliable operation of the system, routers usually increase the redundancy of the system by adding a main control board, that is, adopting the mode of dual main control boards or one main control board and one standby main con...
