Abstract
Description
technical field
[0001] The invention relates to telecommunication equipment in the field of communication, especially next-generation network equipment with large capacity and high density. Background technique
[0002] The communication network has high requirements on reliability, especially the high-level telecommunications equipment at the site, which requires redundant design and backup strategy. The general redundancy design has 1+1 or N+1 redundancy, and the backup strategy is divided into load sharing mode or master-backup mode. For mutual active and standby units, the usual switchover strategy is that the unit regularly detects the state of itself and the backup unit and compares them. perform business in the system.
