The method comprises the following steps: 1, a main control panel controls the completion of the establishment and the synchronization of routes; 2, a light monitoring passage plate is used for completing the sending of local net element ECC data, the receiving of ECC data on light paths and the maintenance of dynamic route tables. The method of the present invention reduces the processing links of ECC passages by a method that ECC routes are identified on the light monitoring passage plate, enhances the efficiency and the reliability of the data transmission of ECC passages and can be applied to multiple joint light transmission networks with complicated networking.
Description
Technical field
The present invention relates to optical transmission dense wave division multipurpose field, be specifically related to Embedded Control Channel in the dense wavelength division multiplexing system (ECC) processing method of data.
Background technology
ECC communication is provided at the function that transmits network management information between the dense wave division multipurpose network element device.In whole network management system, protocol stack subsystem provides the communication interface environment (SOCKET API) of a unanimity for whole system, and the webmaster application program is by protocol stack subsystem and network management center's communication.
The ECC protocol stack is mainly realized peer-peer protocol and Routing Protocol.
Peer-peer protocol (PPP) module, on forming, PPP one has three parts: a kind of agreement that encapsulates multiprotocol datagram; A LCP (LCP) is to be used for setting up, disposing, safeguard, detect, disconnect point-to-point connection; One group of Network Control Protocol (NCPs) that is used for setting up and disposing the heterogeneous networks layer protocol.
The dynamic routing protocol module, the dynamic routing aspect adopts routing information protocol (rip) or OSPF (OSPF).
Traditional E CC flow chart of data processing: after taking each network element to carry out light/electric conversion for the processing mode of ECC data (producing and termination) by Optical Supervisory Channel plate (OSC) receiving light path data by master control borad (NCP), the ECC data that receive are sent to the NCP plate of this network element, receive by the NCP plate, judge whether the data that need receive for this network element, if not, then mail to the OSC plate by NCP again, by the OSC plate carry out that data are compound, framing is handled and light/electric conversion after pass toward next network element.
The processing mode of this ECC data has limitation to a great extent.Because along with increasing of node number, each node all needs the ECC data are sent to the NCP plate, and the ECC data transmission efficiency is not high like this, particularly for the packet switched data processing mode of taking in order to solve clock problem.
Summary of the invention
Technical problem to be solved by this invention is to overcome above-mentioned shortcoming, has proposed a kind of data transmission method that whether is led directly to by Optical Supervisory Channel plate judgement route decision ECC packet, to make full use of the bandwidth of monitor channel, improves the efficiency of transmission of ECC data.
The transmission method of Embedded Control Channel data of the present invention may further comprise the steps:
1, master control borad control finish the foundation of route and Optical Supervisory Channel plate circuit by synchronously;
2, the Optical Supervisory Channel plate is finished the maintenance that sends ECC data and dynamic routing table on this network element ECC data and the receiving light path.
Adopt the method for the invention, adopt the method for on the Optical Supervisory Channel plate, discerning the ECC route to reduce the processing links of ECC passage, improved the efficient and the reliability of the transmission of ECC channel data, can be applicable to the multinode optical transport network of networking complexity.
Description of drawings
The flow chart that Fig. 1 system data is handled.
Fig. 2 is that master control borad and Optical Supervisory Channel plate circuit are by synchronous flow chart.
Fig. 3 is the flow chart that the Optical Supervisory Channel plate sends this network element ECC data.
Fig. 4 is the flow chart that the Optical Supervisory Channel plate receives the ECC data.
Embodiment
The present invention is further illustrated below in conjunction with the drawings and specific embodiments.
The flow process that system data is handled as shown in Figure 1, the foundation that route is finished in master control borad control is synchronized to OSC then; OSC receives data, judges this Data Source, if these data are data of sending from NCP, then the information according to routing table sends to corresponding ports; If these data are data of receiving from opposite end OSC, judge then whether these data are the data of this network element, if then issue NCP, otherwise send to corresponding ports according to the information of routing table.
Master control borad and Optical Supervisory Channel plate circuit are by synchronously as shown in Figure 2, after Link State changes, NCP utilizes RIP2 or OSPF to finish the foundation of routing table, then routing table being issued OSC carries out synchronously, all to apply for routing table after OSC starts each time on the other hand to NCP, after NCP receives request, give OSC routing table synchronously.
Send this network element ECC data procedures as shown in Figure 3, after the OSC plate is received data from NCP, earlier judge according to the first byte of this packet whether these data are routing table information, in this way, then save as routing iinformation, otherwise, these data are sent to A light mouth or B light mouth according to the directional information byte in this packets of information.
ECC data procedures on the OSC receiving light path after the ECC data on the OSC receiving light path, judges whether these data are effective IP packet earlier as shown in Figure 4, judges that specifically rule is referring to relevant IP routing algorithm.If these data are connect PPP bag or other non-IP data or routing broadcast message of usefulness, then these data directly are sent to the NCP plate.If other IP bags judge further that then whether its destination address is the NCP plate of this network element, then is sent to NCP, in this way if not then sending from another light mouth.
