Problems solved by technology

This communication method is too simple, and the disadvantages are obvious. First, in the current GFP equipment, there is a certain limit to the length of the GFP service management frame (for example, 64 bytes).
This communication method cannot transmit super long and large amount of management information
Second, due to the lack of a reliable communication mechanism, when there is a problem with the transmission line, causing errors in the transmitted management information, the existing communication methods cannot guarantee the reliable transmission of end-to-end management information

Embodiment 1

[0069] Embodiment 1. A management information communication method of a GFP device, comprising:

[0070] When the GFP device needs to send management information to the unconnected peer GFP device, it periodically sends the first information frame to the peer GFP device until it receives the second message containing correct response information returned by the peer GFP device frame, confirm that the peer GFP device is connected;

[0071] When the GFP device needs to send management information to the connected GFP device at the opposite end, send a third information frame containing the management information to the GFP device at the opposite end;

[0072] When the GFP device receives the first or third information frame sent by the GFP device at the opposite end, it returns a second information frame containing correct or incorrect response information;

[0073] The first, second, and third information frames are the payload of the GFP service management frame, and carry th...

Embodiment 2

[0140] Embodiment 2. A GFP device, such as image 3 As shown, including: data transmission module;

[0141]The connection initiating module is configured to periodically send the first information frame to the GFP device at the opposite end when it is necessary to send management information to the GFP device at the opposite end until receiving the correct response information returned by the GFP device at the opposite end When the second information frame is received, it is confirmed that the GFP device at the opposite end is connected;

[0142] The data transmission module is used to send a third information frame containing the management information to the GFP device at the opposite end when it is necessary to send management information to the connected GFP device at the opposite end;

[0143] The response module is used to return a second information frame containing correct or incorrect response information when receiving the first or third information frame sent by th...

Abstract

The invention discloses generic framing procedure (GFP) equipment and a management information communication method thereof. The method comprises the following steps that: when required to send management information to opposite GFP equipment which is not connected with the GFP equipment, the GFP equipment periodically sends a first information frame to the opposite GFP equipment until a second information frame which is returned by the opposite GFP equipment and contains right response information is received, and then is successfully connected with the opposite GFP equipment; when required to send the management information to the opposite GFP equipment which is connected with the GFP equipment, the GFP equipment sends a third information frame which contains the management information to the opposite GFP equipment; and when receiving the first information frame or the third information frame which is received by the opposite GFP equipment, the GFP equipment correspondingly returns the second information frame which contains the right response information or wrong response information, wherein the first information frame, the second information frame and the third information frame are payloads of a GFP service management frame and respectively carry a first frame identifier, a second frame identifier and a third frame identifier.

Description

technical field [0001] The invention relates to the communication field, in particular to a general framing procedure device and a management information communication method thereof. Background technique [0002] The concept of the GFP (Generic Framing Procedure, general framing procedure) protocol is defined in the ITU-T G.7041 standard. The GFP protocol is a new type of data link layer encapsulation protocol for connectionless, which can flexibly support the transmission of various data protocols now and in the future, and provide simple and economical end-to-end connections for Ethernet frames. It has the characteristics of small code extension and no random bandwidth expansion cost, especially suitable for the application of high-speed transmission links. [0003] GFP service frames are divided into service data frames (GDFs) and service management frames (GMFs). The GFP service data frame is used to transmit service data, and the GFP service management frame is used ...
