Method and apparatus for monitoring resource condition as well as communication network

Abstract

The embodiment of the invention discloses a resource state monitoring method, a device and a communication network thereof, which are used for improving network stability. The embodiment of the method includes: obtaining the network event state information of nodes during the period of the network operation process; judging whether the network event state of the nodes is satisfied with the resource state detection triggering condition; if satisfied, detecting the data plane resource state and the controlling plane resource state of the nodes; and then reporting the detected results to the management plane. Moreover, the embodiment of the invention also provides a resource state monitoring device and a communication network thereof. The technical scheme of the embodiment of the invention has the advantages of improving the network stability effectively.

Description

technical field [0001] The present invention relates to the field of communication, in particular to a method and device for monitoring resource status and a communication network. Background technique [0002] Traditional optical networks mainly adopt the networking form of self-healing rings, and the bandwidth utilization rate is not high. Moreover, the static configuration is performed through the network management system, and ring networking is mainly used, and the configuration is relatively complicated, time-consuming, and the bandwidth utilization rate is not high. With the demand for multiple services, high bandwidth, high survivability, and fast connection provision, the network topology will evolve from the traditional ring network to the Mesh network, and the network connection provision method will change from statically assigned permanent connections. The transition is mainly based on soft permanent connections and switched connections based on signaling. Thi...

[0007] In the prior art, the above three synchronization processes will be performed before ASON / GMPLS provides available resources to form a consistent whole network topology. However, during network operation, due to network abnormalities or other The state of the data plane resources is inconsistency, but there is no mechanism in the prior art to detect the state of the control plane resources and the state of the data plane resources during the operation of the network, so once the inconsistency occurs, it will cause the network to malfunction, thereby Affect the stability of the network
