Method for configuration and protection of control channel in IP-based network and method of status transition therefor

摘要

The present invention relates to a method for configuring a control network of high reliability in the IP-based network environment, present a protocol technology for automatic control channel configuration / safeguard (Automatic Control Channel Configuration and Protection). The present invention is detailed in the protected group (Protection Group) -1/3 control channel identification, protection group (Protection Group) -2 control channel identification, automatic transfer, forced switching, protection / switching attribute information query, control channel unavailability advice, hello, protocols, error notification, and consists of a retransmission control channel protection / does not apply to switching technology, general technology and control channel protection / advanced technology applied to switching technology, protection / switching considering the application when the priority of technology switching unicast scheme and priorities selectively support multicasting transfer method that does not consider a and, in particular, "the number of the standby control channel - 1" multicasting during switching can also be tolerated by the link failure.
