Example Embodiment

[0044] The present invention provides a system for realizing network port switching, which includes a local board and a counter board. Both the local board and the counter board respectively include a main port and a spare port. The main port realizes communication with the outside on the board, and the spare port passes through the pair The board realizes communication with the outside. When the above board is the active board, the opposite board is the standby board; when the current board is the standby board, the opposite board is the active board; specifically including the following situations: the current board is the active main control board, and the opposite board is the standby main Control board; or this board is the standby main control board, and the opposite board is the active main control board; this board is the main business board, and the opposite board is the standby business board; this board is the standby business board, and the opposite board is the main b...

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...
