Abstract: A service bandwidth configuring method of is provided by this invention, which includes the following steps: defining various kinds of service classes according to the characteristics of various services provided by a network system; defining various kinds of bandwidth specifications of the network system; establishing the mapping relationships between the various kinds of service classes and various kinds of bandwidth specifications; and configuring the service bandwidth of the network system with the mapping relationships. Besides, this invention also provides a network management system. This invention is intended to be applied to the interfaces between NMS and EMS, or interfaces between EMS and NE, and it facilitates the intercommunication between the network management systems of different manufacturers, and the unified management on network management system or devices from different manufacturers by the upper layer network management system.

Abstract: The present invention discloses a method and a system for power saving management. The method includes: a new power consuming state attribute added for existing device object of the communication network management system is configured, wherein the power consuming state attribute is used for indicating the power consuming state of the electrical energy; performing the power saving management on the device by setting the power consuming state of the object corresponding to the device. With the above technical solution, the division of the state information could be clearer and more efficient, meanwhile, the redundancy can be eliminated, in addition, has the feather of wide adaptability.

Abstract: A method for updating a network topology in a multi-protocol label switching system includes that network management system obtains network topology data from a node, then judges whether the current network topology is changed, and when changed, update the local network topology data with the network topology data. A corresponding system is also provided, including an obtaining unit to obtain network topology data from a node, a judgment unit to judge whether the current network topology is changed according to the network topology data and to trigger the update unit when it is changed, and a update unit to update the network topology data in the network management system with the network topology data. In the disclosure, the reality of the Multi-Protocol Label Switching Transport Profile (MPLS-TP) network topology is greatly improved, and it is more convenient and accurate when the network management system is utilized to perform network management.
