Embodiment Construction

[0050] As described in the background technology, the existing forwarding path detection method relies too much on the participation ability of the CPU, and needs to send a large number of detection messages, and the CPU performs analysis of a large number of detection messages. Such a technical solution requires a lot of If the system resources are occupied by other services, the detection efficiency will be affected.

[0051] The present invention proposes a forwarding path detection method, which is mainly based on a switching network architecture system, uses the switching network system to identify and judge messages, and selects paths, so as to efficiently detect link failures between forwarding chips.

[0052] The method proposed by the present invention is applied to a system including a plurality of central processing units CPUs and a plurality of forwarding chips, wherein each CPU transmits the forwarding chip corresponding to the forwarding chip to the corresponding ...

Abstract

The invention discloses a forwarding path detection method and a forwarding path detection device, which can detect forwarding paths among forwarding chips in real time in a mode of combining the CPU and the forwarding chips, not by simply utilizing a CPU to receive and send messages. The invention combines the high-efficiency forwarding function of hardware and the control function of software to reduce the occupation of the CPU and achieve the aims of integrally selecting the message paths and detecting the messages.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a forwarding path detection method and equipment. Background technique [0002] How to detect between the forwarding chips of the switch has always been a difficult point on the switch. In particular, it is necessary to monitor the forwarding paths of all forwarding chips within a limited time, which requires high real-time performance. [0003] Such as figure 1 As shown in FIG. 2 , it is a schematic diagram of a detection method capable of detecting the state of forwarding paths between forwarding chips in real time in the prior art. [0004] In the prior art, the CPU sends a message to the forwarding chip, and then the forwarding chip sends the message to the CPU, that is, to detect whether the forwarding path from forwarding chip A to forwarding chip B is faulty. [0005] In the process of realizing the present invention, the applicant finds that the prior ar...
