Patent ID: 8451855

Claim:
A resource state control system, used in an Automatic Switched Transport Network (ASTN), the resource state control system comprising: a Termination and Adaption Performer (TAP), comprising: a resource state inputting interface, configured to be connected to a termination and adaption function of a transport plane, and to acquire therefrom a resource management state, a resource use state and a resource operational state; a use state outputting interface, configured to be connected to the termination and adaption function of the transport plane and to notify it of the resource use state; a subnetwork point (SNP) adding or withdrawing interface, configured to be connected to a Link Resource Manager (LRM) and to notify it of an adding or withdrawing of the SNP; an SNP binding state outputting interface, configured to be connected to the LRM and to notify it of an SNP binding state; and an SNP operational state outputting interface, configured to be connected to the LRM and to notify it of the SNP operational state; and a plurality of LRMs, each comprising: the SNP adding or withdrawing interlace, configured to be connected to the TAP and to receive the SNP adding or withdrawing notification from the TAP; an SNP binding state inputting interface, configured to be connected to the TAP and to receive the SNP binding state notified by the TAP; and an SNP operational state inputting interface, configured to be connected to the TAP and to receive the SNP operational state notified by the TAP; wherein, in allocating resources to a network element where the TAP is located, the TAP allocates SNPs to the plurality of LRMs, respectively, and notifies them through the SNP adding or withdrawing interface, and then sets the SNP binding state of the plurality of LRMs respectively according to subsequent operations of the plurality of LRMs and notifies the plurality of LRMs of the set SNP binding state through the SNP binding state outputting interface.
