Problems solved by technology

But as mentioned above, the price of dedicated chips is high, such a solution makes the overall cost of the switch system very high
Moreover, the update cycle of the dedicated chip is relatively short. The above-mentioned solution will cause huge waste when updating the dedicated chip, and will also cause huge cost pressure on the system implementer.

Embodiment Construction

[0084] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0085] Referring to FIG. 1 , it is a system schematic diagram of a switch system with port expansion capability provided by the present invention. Wherein, the system CPU1 is connected with a plurality of dedicated chips 2 through the system bus; the uplink port 31 of the low-cost Ethernet switch chip 3 is connected with the dedicated chip 2, and the downlink port 32 of the low-cost Ethernet switch chip 3 is connected with the dedicated chip 2 when needed. Other switch systems, computer systems or other special chips and other equipment are connected.

[0086] The special purpose chips mentioned above can be the same special purpose chip or different special purpose chips, which depends on the function of the special purpose chip required by the switch system with expansion port capability described in the present invention.

Abstract

Some dedicated chips have limited number of physical ports. This imposes restriction on the number of other devices to be connected to and the port number of the switch system, where these chips reside in. Via connecting the dedicated chips with the low-cost Ethernet exchange chips, the invention extends the port number on the dedicated chips without increasing the dedicated chips. In the net switch system, the dedicated chips possessing port-extending function offered by this invention include a port numbering process unit. The physical ports of dedicated chips are connected with the up-going port of the low-cost Ethernet exchange chips. This invention causes the port number supported by the net switch system to increase tenfold. Thus the utility of dedicated chips are raised and the cost of whole net switch system is lowered.

Description

technical field [0001] The invention relates to network communication technology, in particular to a switch system with port expansion capability and a corresponding method for realizing port expansion. Background technique [0002] At present, in the field of computer network communication, more and more network switch systems, such as Ethernet switch systems, are used in network communication, and these switches determine the communication performance of the computer network to a large extent. [0003] The Ethernet switch itself has a system CPU, which is used for the overall control and data processing of the network switch system itself, but if all control, data processing, and data forwarding are completed by the system CPU, then the efficiency of such a switch is very low. Therefore, the current technology trend is to integrate the different functions that the switch needs to implement, including some control functions, processing functions for specific data, and data ...
