Problems solved by technology

[0004] Since the aps protocol is running on the CPU200 side, it will take a certain amount of time for the CPU200 to schedule and switch to the aps thread at this time. This time needs to be determined according to the usage of the CPU200 at that time, so the time cannot be strictly guaranteed.

Embodiment Construction

[0027] The present invention will be described in detail below in conjunction with specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, method, or functional changes made by those skilled in the art according to these embodiments are included in the protection scope of the present invention.

[0028] Such as figure 2 As shown, the method that network processor of the present invention realizes aps switching comprises the following steps:

[0029] a: Detect whether there is any abnormality in the working path, if not, proceed to step a, if yes, proceed to step b;

[0030] b: Obtain the abnormal business exit according to the working path;

[0031] c: Find the corresponding hardware aps entry according to the service exit;

[0032] d: Modify the content of the hardware aps entry to trigger aps switching.

[0033] In this embodiment, in order to ensure mutual communication between devices,...

Abstract

The invention discloses a method for realizing aps switching of a network processor and the network processor. The method comprises the following steps: a, detecting if a working path is abnormal; if not, continuing to execute step a; if it is, executing step b; b, according to the working path, obtaining an abnormal business outlet; c, according to the business outlet, searching a corresponding hardware aps table entry; d, amending content of the hardware aps table entry so as to trigger aps switching. After detecting that the working path is abnormal through the hardware, it is only required to find out corresponding hardware aps table entry and carrying out the aps switching through the hardware; the method avoids long task dispatching time and big software processing cost when CPU (central processing unit) load is big; and thereby, efficiency is improved, and rapid switching of aps is realized.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method for realizing aps switching by a network processor and the network processor. Background technique [0002] With the development of network technology, the requirements of Ethernet equipment for link security are constantly increasing. When the oam (Operation Administration and Maintenance) protocol detects a link abnormality, the core equipment in the network needs to pass automatic protection switching (aps, Auto-protection Switch) protocol to quickly trigger switching. [0003] In current network processors, such as figure 1 As shown, in the network formed between devices A'B'C'D', there are two paths from A' to D', assuming that the working path W' is A' B' D', the protection path P' is A' C' D', so on the device A', the chip 100 detects the working path A' according to the oam protocol B' In the state of D’, if there is an exception between A’B’ a...
