Problems solved by technology
For the data plane, when the number of patch codes is greater than the number of original instruction codes, the instruction space of the network processor is very limited, so the spare instruction space for hot patches cannot be too large, so some slightly large modifications cannot be loaded
[0026] 2. The hot patch modification will involve modifying the data structure, but if the modification involves too many data structures, it will involve some intermediate states, resulting in processing failures
[0027] 3. When adding new functions and patched parts in the microcode need to be modified, because too many patches are applied, a lot of instruction space is wasted, so it is impossible to use hot patches or it is very difficult to implement

Embodiment Construction
[0061] The present invention will be further described in detail below through specific embodiments and accompanying drawings.
[0062] The core technical solution of the present invention is: a method for upgrading the program version of the processing system without interrupting the business, which is suitable for a processing system that uses more than one processing unit with independent instruction space for business processing, and performs business processing in the processing system During the process, upgrade the program of the processing unit to be upgraded one by one; when upgrading the program of a single processing unit: specify a replacement processing unit, load the upgrade program of the processing unit to be upgraded into the instruction space of the replacement processing unit, and use the replacement The processing unit works instead of the processing unit to be upgraded.
[0063] The processing system applicable to the present invention is a processing syst...

The method is suitable to a processing system of using more than one processing unit with independent instruction space. In procedure of processing service by the processing system, the method carries out program upgrade for processing units needed to upgrade one by one. When upgrading program for single processing unit, the method appoints alternative processing unit, and loads upgrade program for processing unit to be upgraded to instruction space of the alternative processing unit. Using the alternative processing unit replaces operation of the processing unit to be upgraded. Features are: upgrading scale is not limited by instruction space of processing system.
Description
technical field [0001] The invention relates to the technology for upgrading the program version of the processing system, in particular to a method for upgrading the program version of the processing system without interrupting the business. Background technique [0002] Reliability and availability are a fundamental requirement for high-end communication processing systems. The reliability and availability of a general communication processing system are measured by the service interruption time within a certain period of time (for example, within one year). The communication processing system is generally composed of programs and hardware. The hardware part can be very durable after the design is mature. There are some deficiencies (Bugs) to be avoided. In addition, due to the rapid development of technology and the emergence of new business features, it is inevitable to upgrade the program version. [0003] The program processing system is divided into control plane an...
