Abstract
The present invention relates to a system and method for protecting a virtual circuit in a dynamic multi-domain environment, the system comprising: a request agent (RA) for transmitting, if a network service is requested from a user terminal, a network resource allocation request signal for providing the requested network service to a global network service agent (NSA); the global network service agent (NSA) for managing at least one or more provider NSAs existing in one composition domain and managing data plane status information of primary/backup virtual circuits of each domain on the basis of information received from the at least one or more provider NSAs; and the at least one or more provider NSAs for configuring, according to reception of the network resource allocation request signal, a network device and the primary and backup virtual circuits, monitoring whether a failure occurs in the configured virtual circuits and network device, and transmitting link/node failure/recovery information and protection/regeneration success/failure information to the global NSA.
