Control method and system for packet transmission

Abstract

A control system for packet transmission. A forward control unit receives a packet providing a port count through an input port and implements a lookup operation. A queue control unit determines whether the port count is greater than a first predetermined value, and, if not, outputs the packet through a first port, and, if so, sends a first message. A multicast forward control unit receives the first message, adds one to a first packet count, determines whether the first packet count is greater than a threshold value, and, if so, sends a stop forward message to the forward control unit but does not send a grant message. The forward control unit receives the stop forward message and does not transmit subsequent packets to the first port but to a second port directly.

Description

technical field [0001] The present invention relates to a packet transmission method, in particular to a packet transmission control method and system. Background technique [0002] Local Area Network (LAN) is usually within the same building or within the area of ​​the same factory that does not cross public roads. In this area, copper wires and optical fibers can be used to connect computers to each other. It is a local area network. [0003] To form a local area network, the main basic components include host (Host), node (Node), client (Client), server (Server) and workstation (Workstation) and so on. [0004] As long as it is the main device connected to the network, almost all of them can be called hosts, such as servers, routers (Router), terminals, workstations and so on. All devices connected to the network that are not part of the network line can be called nodes, such as modems, switches, and so on. Each component in the local area network needs to be connected ...
