Problems solved by technology
In actual work, the current process of using and reclaiming circuit resources at the transport network layer is as follows: Figure 1-2 As shown, when a certain service is no longer needed, the occupied circuit resources often cannot be effectively recovered, and long-term accumulation will cause the line resources to be occupied by a large number of invalid services and resource bottlenecks will appear.
Even if resource recovery is carried out regularly and uniformly, it will consume a lot of manpower and time due to operations such as business validity check, circuit removal, and resource management system update.
Therefore, circuit resources cannot be recovered in a timely and effective manner, and resource recovery consumes a lot of manpower and time, which is the biggest defect of the current method.

Embodiment Construction
[0060] When the F(X) value is greater than 0, no operation is performed;
[0061] When the F(X) value is equal to 0, the network management system sends a circuit deletion request to the ASON control plane through the interface of the ASON control plane, and the ASON control plane deletes all data configurations corresponding to the certain circuit, and the circuit resources are automatically recovered.
[0062] The ASON (Automatically Switched Optical Network) is not a protocol or a collection of a series of protocols. It is a complete system that defines the components of the light control layer and the interactive functions between the various components. It also defines which component or which interactive function plays a role when devices from different manufacturers are interconnected, and further forms a standard.
[0063] ASON introduces the concept of dynamic routing and signaling into the transmission network for the first time, and can realize seamless connection ...

The invention discloses a method for automatically recovering circuit resource in a transmission network, which comprises: setting a circuit effective time parameter while creating a circuit; synchronizing all the transmission net elements and webmaster system times in the whole transmission network by using an NTP protocol; then monitoring the effective time parameter of each circuit in the transmission network by the webmaster system, while comparing the effective time parameter of each circuit with the webmaster system self time parameter and judging through a comparison function F(X) by the webmaster system. When the F(X) value is zero, the webmaster system sends a circuit delete request to an Automatically Switched Optical Network (ASON) control plane through an interface of the ASON control plant; the ASON control plane deletes all the data configuration corresponding to the circuit, and automatically recovers the circuit resource. By utilizing the NTP protocol and ASON technology in the transmission network, the invention realizes the circuit resource automatic recovery, avoids resource waste, and effectively increases transmission network resource utilization ratio.
Description
technical field [0001] The invention relates to the technical fields of transmission and IP, in particular to a method for automatic recovery of transmission network circuit resources. Background technique [0002] The development of modern transmission technology makes the transmission network management function more and more powerful, and the circuit scheduling is more convenient. However, the circuit resource management of the transmission network still relies on the manual scheduling, statistics, and recording of network maintenance personnel. Once a new service requirement arises, maintenance personnel must manually create a new circuit on the network management to support the service; and when the service is no longer needed, at the transmission network level, the circuit still needs to be manually removed to realize the transmission network circuit resources. recycling. [0003] At present, the management of circuit resources on the transmission network relies on m...
