Problems solved by technology

[0012] In the process of realizing the present invention, the inventor found that there are at least the following problems in the prior art: different patch making tools are required for different network processing; after the file is patched, the patch file is stored separately and a jump instruction is inserted, so Its physical code structure will change, and when there is a newer version of the program that needs to be upgraded, the difference between the previous version and the previous version cannot be compared in the same way, so it is not possible to continue to apply new patches after patching

Embodiment Construction

[0030] In order to solve the problems that the prior art cannot be commonly applied to all network processors and cannot be patched continuously, the present invention provides a network processor patching method and device. The present invention will be described in detail below in conjunction with the accompanying drawings.

[0031] Such as figure 2 As shown, the patch method of the network processor provided by the embodiment of the present invention includes:

[0032] 201. Quickly interrupt receiving data traffic;

[0033] The patching method of this embodiment needs to perform the patching operation when the network processor has no data traffic processing, so the receiving data traffic is quickly interrupted first.

[0034] In this embodiment, the method for quickly interrupting the received data flow includes:

[0035] Stop receiving data from upstream devices by controlling the network processor;

[0036] If the capacity of the network processor to process data ex...

Abstract

The invention discloses a patching method and a device for network processors, which relates to the network field, and aims at solving problems of the prior art that different network processors need different patch makers, the existing patch makers can not be applied to all the network processors universally, and the prior art can not perform continuously patching to network processors. The invention provides the technical scheme including a patching method for network processors, wherein the method comprises steps of stopping threading, downloading codes of a new procedure to replace the original codes, and restarting threading.

Description

technical field [0001] The invention relates to the network field, in particular to a patching method and equipment for a network processor. Background technique [0002] Patching is a mechanism to upgrade software to solve known software problems without restarting the device or affecting the normal operation of the business. For communication-level products, the requirements for service interruption time are very strict when upgrading software, and the interruption time should be controlled within the range of 20 milliseconds. Therefore, in order not to affect the normal processing of online users and business data, patching is usually used. Carry out product upgrades. [0003] The prior art mainly adopts the following methods for patching network processors, such as figure 1 Shown: [0004] Step 101, obtaining the program code of the original version and the program code of the new version; [0005] Step 102, find out the difference code between the program code of th...
