Abstract: Disclosed are a method for implementing a virtual network and a network management system. With the method, a virtual network is created; multiple super ports each unique in the virtual network are created; a connection of a super port with a network element is configured; and when a service to pass through the virtual network or a nonterminal service interconnected to the virtual network is created, the super ports are used as routing resources of the service. With the disclosure, by using a virtual network as well as super ports and a connected group provided by the virtual network, an end-to-end service transparently passing through a third-party network can be created, such that unified transparent end-to-end service management may be provided at a customer side, greatly facilitating network management in this scenario, reducing a risk in network management and improving network reliability.

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 provides a method for establishing a route of a connection, which comprises: a route relation group is configured on a service node responsible for route calculation; the route relation group comprises a connection in which the service node is contained and other connections having route relation with the connection; when a route of a connection is requested to be established, the service node responsible for route calculation confirms the route of the connection according to the route relation group configured on the service node, and then establishes the route of the connection. A device for establishing a route of a connection is also provided in the present invention. With the present invention, the problem of high probability of route conflict in the existing connection route establishment process can be solved.

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.

Abstract: The disclosure discloses a method for processing a Tandem Connection Monitoring (TCM) level, which comprises: obtaining a route of a service which needs to be configured TCM, obtaining a TCM segment on the route of the service, determining a TCM segment which needs to be configured from the obtained TCM segment, and allocating a TCM level for the TCM segment which needs to be configured according to a segment relationship between the TCM segment which needs to be configured and a configured TCM segment. The disclosure further discloses an apparatus for processing a TCM level. By means of the disclosure, a TCM level can be automatically allocated for a TCM segment and environment of multiple network applications can be applicable.
