Problems solved by technology
However, in general, the time from equipment failure to normal operation of the equipment is limited by various aspects. Generally, the interruption time is hundreds to thousands of milliseconds, and the call requests reported during this period will be discarded. There is no guarantee that the business will not be affected at all

The invention belongs to the communication technical field, and provides an operation shifting method and veneers. The method is realized by that: during shifting operation among veneers, when the veneers undergoing the operation shift is an interface veneer, the data sent to the interface veneer is cached into a cache unit of an opposite-end network element which is connected with the interface veneer; when the veneer undergoing the operation shift is of another operation veneer except for the interface veneer, the data sent to the operation veneer undergoing operation shift is cached into a cache unit which is in the same network element with the operation shift veneer; when the operation shift is completed among the veneers, the cached data is sent back to the veneer which finishes the operation shift. Using the invention can avoid operational interrupt during the fault or the update of the operation veneer, and the shifting among the operations.
Description
technical field [0001] The invention relates to the technical field of communication, in particular to a service switching method and a single board. Background technique [0002] With the continuous development of telecommunications technology, many telecommunications equipment need to be upgraded in order to expand functions and add new services, or to find problems during the operation of telecommunications equipment. However, telecommunication equipment has relatively high reliability requirements. General telecommunication equipment requires 99.999% reliability, that is, only 5 minutes of interruption time are allowed each year. How to reduce the service interruption time during equipment upgrade, or even keep the service uninterrupted during the equipment upgrade process, has always been a matter of great concern to telecommunication equipment manufacturers and operators. [0003] Existing technology 1: In order to ensure that key network element failures or upgrades ...
