Method and apparatus for network diagnosis processing

An instruction center, comprising:

• a computing hardware;
• and a non-transitory computer-readable storage medium including computer-executable instructions executed by the computing hardware to perform, on the instruction center, operations comprising:
• sending a network diagnosis instruction to a first network layer of a first network tunnel source end, so that the first network tunnel source end sends, at the first network layer of the first network tunnel source end, a diagnosis message to a first network layer of a first network tunnel peer end and a second network layer of the first network tunnel source end, and the second network layer of the first network tunnel source end sends the diagnosis message to a second network layer of the first network tunnel peer end, wherein the diagnosis message comprises characteristic information;
• receiving diagnosis results that are reported by the first network layer of the first network tunnel peer end, the second network layer of the first network tunnel peer end, and a third network layer of the first network tunnel peer end according to the diagnosis message, wherein the diagnosis result comprises the characteristic information;
• performing, according to the characteristic information, an association analysis on the diagnosis results that are reported by the first network layer of the first network tunnel peer end, the second network layer of the first network tunnel peer end, and the third network layer of the first network tunnel peer end;
• receiving diagnosis results that are reported by a first network layer of a second network tunnel peer end, a second network layer of a second network tunnel peer end, and a third network layer of a second network tunnel peer end according to the diagnosis message, wherein the diagnosis result comprises the characteristic information;
• performing, according to the characteristic information, an association analysis on the diagnosis results that are reported by the first network layer of the first network tunnel peer end, the second network layer of the first network tunnel peer end and the third network layer of the first network tunnel peer end and by the first network layer of a second network tunnel peer end, the second network layer of a second network tunnel peer end, and the third network layer of the second network tunnel peer end, wherein the characteristic information is used to associate the diagnosis results reported by the first network layer of the first network tunnel peer end, the second network layer of the first network tunnel peer end, and the third network layer of the first network tunnel peer end and by the first network layer of a second network tunnel peer end, the second network layer of a second network tunnel peer end, and the third network layer of the second network tunnel peer end.

A network node device, wherein the network node device is a first network tunnel source end comprising:

• a computing hardware;
• and a non-transitory computer-readable storage medium including computer-executable instructions executed by the computing hardware to perform, on the network node device, operations comprising:
• receiving, at a first network layer of the first network tunnel source end, a network diagnosis instruction sent by an instruction center;
• sending, at the first network layer of the first network tunnel source end, a diagnosis message to a first network layer of a first network tunnel peer end and a second network layer of a first network tunnel source end, wherein the diagnosis message carries characteristic information, so that the first network tunnel peer end reports, at the first network layer of the first network tunnel peer end, a diagnosis result comprising the characteristic information to the instruction center;
• sending, at the second network layer of the first network tunnel source end, the diagnosis message to a second network layer of the first network tunnel peer end, so that the first network tunnel peer end reports, at the second network layer of the first network tunnel peer end, a diagnosis result comprising the characteristic information to the instruction center;
• and
• associating, using the characteristic information, the diagnosis results reported by the first network tunnel peer end at the first network layer of the first network tunnel peer end and at the second network layer of the first network tunnel peer end.
