Data forwarding system and method, computing equipment and programmable logic device

Abstract

The embodiment of the invention is applicable to the technical field of computer networks, and provides a data forwarding system and method, computing equipment and a programmable logic device.The system comprises a main network port, at least one sub-network port and a sub-network port switching module, and the sub-network port switching module comprises an uplink arbitration sub-module and a downlink arbitration sub-module; the uplink arbitration sub-module comprises a sub-network port receiving and processing unit, a cache array data polling unit and a sending data cache array; the downlink arbitration sub-module comprises a data forwarding control unit and a main network port receiving and processing unit; the uplink arbitration sub-module is adopted to forward an uplink datagram received by the sub-network port to the main network port; a downlink datagram received by the main network port can be forwarded to the corresponding sub-network port by adopting the downlink sub-module. The system can flexibly control network ports corresponding to data forwarding, and accurately forward datagrams, so that the energy consumption of the system is reduced.

Description

Technical field [0001] The present application belongs to the field of computer network technology, in particular involving a data forwarding system, methods, computing devices and programmable logic devices. Background [0002] At present, almost all domestic switching chips are multi-port universal structure, this type of domestic switching chips have the advantage of versatility, but the number of ports of this type of chip is larger, and in some application scenarios where the number of network ports is less, some network ports will be idle, so the power consumption of the switching chip is too high. In addition, the universal data exchange function cannot accurately forward packets to the specified port according to the specified physical address. Contents of the Invention [0003] In view of this, the present application embodiment provides a data forwarding system, a method, a computing device and a programmable logic device for achieving high performance and low power c...

Problems solved by technology

[0002] At present, almost all domestic switch chips have a multi-port general-purpose structure. This type of domestic switch chip has the advantage of versatility, but this type of chip has a large number of ports. In some application scenarios that require a small number of network ports, it will Some network ports are idle, which leads to high power consumption of the switch chip

In addition, the universal data exchange function cannot accurately forward packets to the specified port according to the specified physical address
