Abstract

The embodiment of the invention provides an ISSU data communication method and a network device, related to the technical field of computer. The ISSU data communication method is applied to the network device in which a distributed operating system runs; the network device comprises a plurality of cards, wherein the first card is installed with an application with a first version, and the second card is installed with an application with a second version. The ISSU data communication method comprises the following steps: the first card obtains communication data to be sent, wherein the communication data comprises the identification of a preset member parameter and a parameter value of the preset member parameter; then structured text data is generated; the first card sends the structured text data to the second card; the second card inquires a target parameter value corresponding to the identification of a target member parameter from the structured text data; the second card assigns the locally stored target member parameter of the first card according to the target parameter value. By means of the ISSU data communication method and the network device, the parameter value of eachmember parameter can be parsed without the need of rules, therefore, the parsing errors can be effectively avoided.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a method and network equipment for uninterrupted service upgrading ISSU data communication. Background technique [0002] In-Service Software Upgrade (In-Service Software Upgrade, ISSU) is an upgrade method that can ensure that services are not interrupted or the interruption time is relatively short during the upgrade process. The network device is provided with multiple boards, for example, multiple main control boards and multiple interface boards, and each board stores an application program. When using the ISSU function to upgrade, the ISSU upgrade is usually performed on a board-by-board basis. [0003] In practice, each board will communicate in real time to ensure data synchronization in network devices. During the ISSU upgrade process, the communication process between the upgraded board (which can be called the first board) and the non-upgraded board (whic...
