Method for concatenating network exchange chip and correlation device

Abstract

A method of series connect network exchange chips and the relative devices to series joint the first and the second network exchange chips. Each network exchange chip contains several network interfaces and a high-speed network interface; form these high-speed network interfaces to direct connection, make the network exchanger provide with the number of network interfaces according to the first and the second network exchange chips and the number is the sum of the first and the second network exchange chips; the first and the second network exchange chips upgrade the internal operation state for each other through the direct connection to manage the data exchange of the first and the second network interfaces. Each network exchange chip has a requiring form and the two exchange chips can upgrade the contents of the requiring forms for each other.

Description

technical field [0001] The present invention relates to a method for serially connecting network switching chips and related devices, in particular to a method for directly linking two network switching chips in series by using a high-speed network connection port, so that the total number of network connection ports provided to the outside is equal to the network of the two network switching chips The sum of the number of connected ports. Background technique [0002] The traditional Ethernet (Ethernet) using twisted pair, no matter the transmission rate is 10Mbps or 100Mbps, needs to connect the workstation and the server through the Ethernet hub (Hub) to share network resources, and the bandwidth of the hub is determined by all connections. shared by workstations on the network. When there are more network users, the situation of network collision (collision) will be more serious, and at the same time, the bandwidth that each user can use will be less. Today, when multim...

Problems solved by technology

[0004] Although network switches can improve the shortcomings of traditional hubs, the number of network connection ports that a single hub can provide is still limited; and simply connecting two or more network switches or network switching chips (switch controllers) in series, although The number of network connection ports that can be provided in appearance has increased, but if the network switches are connected in series, problems may arise, such as (1) unable to share the congestion status of each other's network connection ports and continue to deal with congestion If the network connection port in the network transfers data, it may not only cause the consequences of data leakage, but also drag down the operating efficiency of the entire series-connected network switch group; (2) the data output to some connection ports may have to go through multiple Only by looking up the table once can the destination be known, which will cause the overall data transmission time to be forced to be extended, which is not in line with the time and economic benefits
