Problems solved by technology

However, this also faces new problems. The engine boards with network processors have limited processing capabilities, which cannot meet the traffic processing requirements of all interface boards, and are limited by device size and power consumption. It is impossible to integrate more network processors into the In this way, the system must provide a method that can share the traffic of different interface boards among multiple engine boards, so as to improve the processing capacity of the whole machine and meet the traffic processing requirements of network backbone nodes.

Embodiment Construction

[0030] The port aggregation function is applied between the internal interface board and the engine board of the data communication equipment, and each engine board is assigned a virtual physical port to join the port aggregation group. The virtual port is not a real physical port on the panel, but the virtual port number is included in the port table space of the system, and can be identified as the incoming and outgoing port of the message in the system. For example, port 31 of the engine board of Slot2 actually does not have this physical port on Slot2, but within the system, other interface boards can forward packets to port 31 of Slot2, so that the engine board can receive the packets.

[0031] Port aggregation groups need to be configured on all interface boards. In this way, no matter which interface board receives the packet, when it needs to be forwarded to the engine board for processing, it is actually forwarded to the port aggregation group. As a logical port, the ...

Abstract

This invention provides a method for balancing the load of service flows on an engine board card responsible for processing logic in the system, which applies the port accumulation function between the internal interface boards and the engine boards of the data communication device, each engine board assigns a virtual physical port in a port accumulation set.

Description

technical field [0001] The invention belongs to the technical field of data communication, and in particular relates to the sharing and redundant backup of interface flow in a plurality of processing engines inside the device in a rack-type data communication device. Background technique [0002] In rack-mounted data communication products, the system contains multiple boards, which jointly complete data forwarding processing, system control and other functions. The boards responsible for data forwarding and processing are divided into main control boards, interface boards and engine boards. Such as figure 1 As shown, the main control board is the control center of the system and runs the system control software. Responsible for equipment management and maintenance, receiving user input control, and running various application protocol modules including routing protocols, network management protocols, link layer protocols, etc. The main control board manages and communica...
