Problems solved by technology

Generally, there are multiple HiGig ports connected between the SFU and each service line card, and the traffic is balanced and shared. If a HiGig port is abnormal and cannot be quickly and accurately detected and processed, the cross-card forwarding will cause serious packet loss, even if The data flow is not large, and there will be a large amount of packet loss, which will cause customer business interruption and cause heavy losses

Embodiment

[0033]On each board, the working status of the HiGig port is defined as four types: idle, ready, forwarding and error. Only when the HiGig port is in the forwarding state, can it be added to the aggregation group or the distribution panel port for use. In other cases, the HiGig port is not available, and the HiGig port is in the idle state during initialization. When the physical link of the HiGig port is detected to be UP (interrupt notification) and the opposite board is ready, the HiGig port state switches from the idle state to the ready state. Enable the HiGig connectivity detection task on the business line card and the switching network board, and perform HiGig connectivity detection on the HiGig port in the ready and forwarding state by sending and receiving probe messages: the detection is successful, if HiGig is in the ready state, it will switch to the forwarding state ; The detection fails. If HiGig is in the forwarding state, it will switch to the ready state. If HiGi...

Abstract

The invention discloses a method for realizing reliable data plane communication. The data plane supports higig protocol, the CPU control unit of a network board and the CPU control unit of a service line card mutually send a detection message by a higig port in certain period, and the connectivity of all the higig ports is detected; if finding any abnormal port, the data flow of the higig port is switched to the other higig ports in normal operation, and when the higig port is detected to be in normal again, data flow is redistributed to the port again. By applying the invention, data is avoided to be forwarded to an abnormal higig channel, thus ensuring the reliability of data plane communication.

Description

Technical field [0001] The present invention relates to the field of network communication, in particular to the technology of reliable communication of the data plane of routing and switching equipment. Background technique [0002] At present, the system architecture of mainstream routing and switching equipment is generally divided into three subsystems: data plane, control plane, and monitoring plane. Among them, the data plane is composed of a switching matrix and a switching chip unit of a business line card, which is responsible for the service data processing and forwarding of the entire system; compared with other planes, the data plane occupies the most system resources and plays a decisive role in the performance of the entire device. There are two main design and implementation schemes for the data plane: The first is to design the switch matrix and the main control board as a whole, such as figure 1 As shown, the data plane is composed of a switch matrix unit on a m...
