Problems solved by technology

In the TCP / IP protocol stack, the specified interface transmission is not a standard implementation. To realize the specified interface transmission, it may be necessary to expand the existing protocol stack, which leads to the complexity of the implementation, and there may be hidden dangers in the interoperability of various manufacturers.

Embodiment Construction

[0036] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0037] In the embodiment of the present invention, both the trace message and the test message are messages defined in RFC4207 (SDH Encoding for LMP Test messages).

[0038] image 3 It is the view defined by RFC4207 for tracking objects, which will be referred to below image 3 To describe in detail RFC4207's definition of tracking objects.

[0039] Such as image 3 As shown, Trace Type (trace type): indicates the type of Trace Message (trace message), defined as follows:

[0040] 1=SONET Section Trace(J0 Byte)

[0041] 2 = SONET Path Trace (J1 Byte)

[0042] 3 = SONET Path Trace (J2 Byte)

[0043] 4=SDH Section Trace (J0 Byte)

[0044] 5=SDH Path Trace (J1 ...

Abstract

A method and an apparatus for verifying connectivity of a data are applied in the adjacency discovering procedure of the automatically exchanging optical network to verify the connectivity of the data. The method comprises steps: reconstructing the trace object in the SDH coding of the link manage protocol testing message to enable the trace message carry the information of the trace type; when discovering the adjacent layer, constructing the trace message object by the trace agent, sending the trace message to the transmitting plane and requiring the transmitting plane to send the message bythe trace byte based on the predetermined form; and when the receiving port of the adjacent layer in the transmitting plane receives the trace message, carrying the different process based on the trace type carried in the trace message. The complexity of realization and the hidden trouble lying in the interconnection caused by the different message sending mechanism in the adjacent layer discovering procedure are resolved, and the transmitting mechanism and the verify flow in the data verifying procedure are unified.

Description

technical field [0001] The present invention relates to the field of optical network, and more specifically, relates to a method and a device for performing data connectivity check in the process of automatic switching optical network layer adjacency discovery. Background technique [0002] In the telecommunications field, optical transmission network (OTN for short), wavelength-division multiplexing (WDM for short), synchronous digital hierarchy (SDH for short) or synchronous optical network ( Optical networks such as Synchronous optical network (abbreviated as SONET) transport network have been widely used. [0003] Automatic switched optical network (ASON for short) is a research hotspot in the field of optical network in recent years. The concept of ASON is proposed in the ITU-TG.8080 proposal, and the functions of the ASON network are completed by setting a special control plane (Control plane, CP for short). ITU-T (International Telecommunications Union) stipulates i...
