Abstract

The present invention provides a method for sending and receiving the network management messages and/or the control messages, that is, using GFP protocol in stead of conventional LAPD protocol, predetermining the mapping relationship between the values of UPI field in GFP protocol and the types of the data including the network management messages and/or the control messages, furthermore, filling the UPI field of GFP protocol based on the corresponding mapping relationship, encapsulating the network management messages and/or the control messages via GFP protocol into SDH/SONET, PDH or OTN, and transmitting the encapsulated data. GFP protocol is a universal protocol, allowing for inter-operation of the network management messages and the control messages between the equipments of different manufacturers.

Claims

1. A method for sending the network management messages and/or the control messages, comprising the following steps:

1) when network layer data arriving, a source judging the types of the data;

2) based on the predetermined mapping relationship between the values of UPI field in GFP protocol and the types of the data including the network management messages and/or the control messages, the source filling UPI field and performing GFP encapsulating;

3) the source performing physical layer processing to the data having been GFP encapsulated;

4) the source sending the data and the data having been physical processed and then transmitted to sink.

3. The method for sending the network management messages and/or the control messages according to claim 1, wherein the physical layer processing is SDH/SONET processing.

4. The method for sending the network management messages and/or the control messages according to claim 1, wherein the physical layer inverse-processing is SDH/SONET inverse-processing.

5. The method for sending the network management messages and/or the control messages according to claim 1, wherein said network management messages are CLNP messages.

6. The method for sending the network management messages and/or the control messages according to claim 1, wherein said control messages are Ipv4 and Ipv6 messages.

2. A method for receiving the network management messages and/or the control messages, comprising the following steps:

1) a sink receiving the data sent from a source;

2) the sink performing physical layer inverse-processing to the data received;

3) the sink performing un-encapsulating to the data having been physical layer inverse-processed and reading out UPI field in GFP protocol;

4) based on the predetermined mapping relationship between the values of UPI field and the types of the data including the network management messages and/or the control messages, the sink identifying the types of the data corresponding to the value of UPI field and performing corresponding processing to the different types of the data.

7. The method for receiving the network management messages and/or the control messages according to claim 2, wherein said network management messages are CLNP messages.

8. The method for receiving the network management messages and/or the control messages according to claim 2, wherein said control messages are Ipv4 and Ipv6 messages.
