Problems solved by technology

The interface upgrade of chip and equipment manufacturers will also lead to some interface problems
When 40G and 100G interfaces are applied, the original interface using the internal switch chip does not support or the interface of the new switch chip does not support well. This has become a problem for equipment manufacturers to make the original network equipment compatible with external high-speed interfaces.

Embodiment Construction

[0014] The present invention will be further explained below in conjunction with the accompanying drawings.

[0015] like figure 1 As shown, a data packet forwarding processing system provided by the present invention, the system realizes its data packet forwarding function based on an FPGA chip, wherein the FPGA chip is connected to the line side interface, the QDR database and the switching chip respectively. After the data packet is input, after querying the table items in the external QDR, the relevant information is encapsulated into the data packet and then distributed to each system side interface. It is forwarded to the switch chip through the system side interface; the sent data packet is received and buffered by the system side interface, and the data packet is aggregated to the interface sending buffer and then sent out through the interface.

[0016] like figure 2 As shown, a data packet forwarding processing system provided by the present invention mainly inclu...

Abstract

The invention provides a data packet forwarding processing system which comprises a sending side unit and a receiving side unit. The input end of the sending side unit and the output end of the receiving side unit are connected respectively with a plurality of exchange chips. The output end of the sending side unit and the input end of the receiving side unit are connected respectively with line side interfaces. The data packets inputted by the exchange chips are converged through the sending side unit and are then transmitted to the line side interfaces. The data packets inputted by the line side interfaces are subjected to information identification through the receiving side unit and are then transmitted to the corresponding exchange chips. The invention also provides a data packet forwarding processing method. The invention effectively solves the problem faced by communication equipment that a large capacity interface cannot be compatible with a small capacity interface and at the same time, solves the problem with the data packet forwarding processing of the two. The system and the method of the invention can not only be simply realized at a low use cost, but are also faster and more convenient. The forwarding speed is also high; and the transmission speed is also effectively increased.

Description

technical field [0001] The invention belongs to the field of network communication, in particular to a data packet forwarding processing system and method. Background technique [0002] With the development of network technology, the wide application of 40G and 100G high-speed interface technology will bring great opportunities for network equipment upgrades. The interface upgrade of chip and equipment manufacturers will also lead to some interface problems. When 40G and 100G interfaces are applied, the original interface using the internal switch chip does not support or the interface of the new switch chip does not support well. This has become a problem for equipment manufacturers to make the original network equipment compatible with external high-speed interfaces. The equipment price is mainly reflected in the single port price. Therefore, reducing the cost of single-port business processing is also the main means for manufacturers to improve product competitiveness. ...
