Traffic control method of network device, traffic control device and network device

Abstract

The invention discloses a traffic control method of a network device, a traffic control device of a network device and a network device. Based on the traffic control method, the traffic control device and the network device of the invention, the logic device of an interface board can encapsulate sending completion information of a data Ethernet message in an outgoing direction in a traffic control Ethernet message so as to report the sending completion information; the traffic control Ethernet message is forwarded to the logic device of a main board by an Ethernet switch chip of the main board; the logic device of the main board obtains the sending completion information through analyzing the traffic control Ethernet message, encapsulates the sending completion information in a traffic control message, and writes the traffic control message into the memory of the main board, so that the CPU of the main board can instantly the read the traffic control message, and thus, the CPU of the main board can instantly sense whether the data Ethernet message in the outgoing direction is congested, and accurate realization of the quality of services (QOS) in the outgoing direction of the network device can be benefitted; and the transmission of the data Ethernet message will not be affected by the reporting of the sending completion information; and the CPU can loosely couple the sending and receiving of the data Ethernet message.

Description

technical field [0001] The invention relates to network technology, in particular to a flow control method for network equipment, a flow control device for network equipment, and network equipment. Background technique [0002] The network equipment can adopt the Ethernet bus architecture, and, in the Ethernet bus architecture, the Ethernet data channel between the CPU of the main board and the Ethernet switching chip of the main board, the Ethernet data channel between the Ethernet switching chip of the main board and the logic device of the interface board, And the interface data channel between the logic device of the interface board and the interface chip of the interface board may have a situation that the physical bandwidth does not match each other. [0003] Therefore, network devices are prone to congestion of data packets in the outgoing direction. If the CPU of the main board cannot sense the aforementioned congestion and the aforementioned congestion relief in ti...

[0002] The network equipment can adopt the Ethernet bus architecture, and, in the Ethernet bus architecture, the Ethernet data channel between the CPU of the main board and the Ethernet switching chip of the main board, the Ethernet data channel between the Ethernet switching chip of the main board and the logic device of the interface board, And the interface data channel between the logic device of the interface board and the interface chip of the interface board may have the situation that the physical bandwidth does not match each other

[0003] Therefore, network devices are prone to congestion of data packets in the outbound direction

If the CPU of the main board cannot sense the aforementioned congestion and its removal in a timely manner, it will be difficult to accurately realize the QOS (Quality of Service) in the outbound direction of the network equipment.
