Problems solved by technology

[0008] 2. The structure of the current transmission network is complex, and more than 90% of the circuits are circuits of the network management system of different manufacturers
Due to the large scale of the network, except for the static data records of business-related information, other information can only be completed by relying on the information reported by the Corba northbound interface of the manufacturer's network management
[0009] 3. The information of the transmission circuit is protected. At present, in the implementation process of the transmission network management, there is no clear method to calculate the complete circuit route and its protection route according to the configuration data reported by the Corba interface.
[0010] 4. The manufacturer's network management can only manage the transmission circuits within the same manufacturer, and cannot manage the end-to-end circuits across manufacturers; and the manufacturer's network management only has the circuit information composed of transmission network elements, but for the DDF, bridge, contact cable, microwave and other information are not recorded, so a real end-to-end circuit cannot be formed; the most critical point is that after the manufacturer's network management queries a complete circuit, it takes a long time to query the next circuit again, and cannot Make a batch query
[0011] To sum up, at present, in the field of transmission network management systems, it is impossible to directly obtain complete end-to-end circuit information that can be used by various applications of the network management system from the manufacturer's network management information

Embodiment 1

[0051] Embodiment 1: Start from any intermediate network element in the end-to-end circuit, and check the information of any end-to-end circuit passing through the intermediate network element. For the specific execution process, refer to image 3 :

[0052] Step 301: The transmission network manager collects the transmission resource data of the entire network through the Corba interface, and obtains accurate transmission resource information of the circuit, that is, the transmission resource information with virtual network element information deleted.

[0053] Step 302: Select any intermediate network element in the circuit as the current network element, check the information of the current network element from the accurate transmission resource information obtained in step 301, and create a data table about the network element in the database.

[0054] Step 303: Record the information of the current network element in the data table.

[0055] Step 304: According to the i...

Embodiment 2

[0060] Embodiment 2: The network element at the starting point of the SNC is used as the starting point, and the circuit is connected in series. SNC is located in the middle of an end-to-end circuit and records the connection information of intermediate network elements. It is a transmission entity for transmitting characteristic information in a subnet. It is composed of terminal points at the border of the subnet and supports transparent end-to-end transmission in the subnet. Therefore, only path information other than SNC needs to be searched. See the specific execution process Figure 4 :

[0061] Step 401: Obtain the transmission resource information of the end-to-end circuit from the data derived from the EMS, that is, the transmission resource information with the virtual network element information deleted.

[0062] Step 402: Select an SNC from the end-to-end circuit, use the network element at the starting point of the SNC as the current network entity, find out the...

Embodiment 3

[0069] Embodiment 3: When the source and destination information of the circuit path is obtained from the network management system of the manufacturer, that is, the network elements of the starting point and the ending point of the circuit can be derived from the network management system of the manufacturer, and the ports where the circuit starts from the starting point and the ending point of the network element information, then you can start from the source end of the circuit, search for the sink end of the circuit, and determine the serial connection of the circuit. For the specific execution process, see Figure 5 :

[0070] Step 501: Obtain the transmission resource information of the end-to-end circuit. The transmission resource information includes the source and sink information of a circuit, that is, includes the information of the A terminal and the Z terminal of the circuit.

[0071] Step 502: Take circuit A as the current network element, find the current networ...

Abstract

The invention discloses a method for acquiring the end to end circuit information in a network management system. The method comprises the following steps: a network entity in the end to end circuit is selected as the current network entity, and the information of the current network entity is obtained and recorded through the acquired transmission resource information of the end to end circuit, all the network entities connected with the current network entity are confirmed, the information of all the network entities is acquired from the transmission resource information, whether each network entity in all the network entities is a terminal point or not is respectively judged according to the information of the judged network entities, if the judged network entity is not a terminal point, the CTP information of the connecting terminal point between the current network entity and the judged network entity is shielded in the transmission resource information, and the network entity is taken as the current network entity, all the network entities connected with the current network entity is continued to be acquired, until the terminal point of the circuit is acquired, and if the judged network entity is the terminal point, and the information of the network entity is recorded.
