Network device and traffic control method and device thereof

Abstract

The invention discloses a network device and a traffic control method and device thereof. A logical device of an interface board is capable of packaging transmitting completion information of data Ethernet messages in the outgoing direction into a traffic control atomic data packet for reporting; the traffic control atomic data packet is capable of forwarding the transmitting completion information to a logical device of a main board through a management bus; the logical device of the main board analyzes the traffic control atomic data packet to obtain the transmitting completion information, packaging the transmitting completion information into a traffic control message, writing the transmitting completion information into a memory of the main board for a CPU (central processing unit) of the main board to read; thus, the CPU of the main board is capable of sensing whether or not the data Ethernet messages in the outgoing direction are jammed in time, and outgoing-directional QOS (quality of service) of the network device can be accurately achieved. Meanwhile, transmission of reporting effect data Ethernet messages of the transmitting completion information can be avoided, and loose coupling between transmitting and receiving of the data Ethernet messages is achieved for the CPU.

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.
