Interface board upgrading method and system

Abstract

The invention discloses an interface board upgrading method and a system. The method includes the following steps: when a category of business needs to be upgraded, uploading a new version of software aiming at a master control board to a new version of control end; and meanwhile, uploading a new version of software aiming at the interface board to a new version of business end. Besides, the method also includes the steps: an old version of control end synchronizes business data to the new version of control end; the new version of control end transmits a control right transfer request to theold version of control end; the old version of control end receives the request and transmits a switch instruction to the old version of business end on the interface board; the old version of business end receives the instruction, synchronizes the business data to the new version of business end and transfers the control right of Socket connection to the new version of business end; and after the transfer, the old version of business end exits, simultaneously, the old version of control end exits and transfers the business control right totally to the new version of control end, and finally the upgrading of the interface board is completed. The method and the system realize the unlimited upgrading of the interface board and ensure no interruption of business and no packet loss during theupgrading process of the interface board.

Description

technical field [0001] The invention relates to the technical field of software upgrading, in particular to an interface board upgrading method and system. Background technique [0002] In a distributed system, the main control board and each interface board work together to complete various business processes. Wherein, the main control board controls the interface board to complete the sending and receiving of service data. When upgrading a service on the interface board, in addition to upgrading the service software on the interface board, the control software on the main control board must also be upgraded. [0003] At present, the following two methods are usually used to upgrade the services on the interface board: [0004] figure 1 The flow chart of the interface board service upgrade method provided for prior art 1, such as figure 1 As shown, the specific steps are as follows: [0005] Step 101: When a type of service is to be upgraded, load the new version softw...

Problems solved by technology

[0015] In the existing technology, once the interface board upgrade is completed by restarting, it will inevitably affect the forwarding

Existing technology 2 completes the interface board upgrade through patching. Although it can guarantee uninterrupted business, it is subject to many limitations of the patch itself, for example: when the function parameter changes include parameter type and number change, or the When the definition is changed, the interface board upgrade cannot be implemented through patches; the patch function cannot refer to statically defined functions or variables, which will limit the upgrade of the interface board; if the function body is too small, it cannot be patched, and the patch usually requires at least 11 items Instructions, if the number of instructions compiled by the function itself is too small, it cannot be patched, which will also limit the upgrade of the interface board
