The topology of the metro network is a graph, and there may be 2, even more than 2 connections between two devices, that is, there may be more than 2 connections between a node switch and a node server, between a node switch and a node switch, and between a node switch and a node server, however, the addresses of the metro networks of the metro network devices are only , and in order to accurately describe the connection relationship between the metro network devices, the parameter label is introduced in the embodiment of the present invention, so that only describes metro network devices.
The Label definition in this specification is similar to the Label definition of MPLS (Multi-Protocol Label Switch), and assuming that there are two connections between device a and device B, there are 2 labels for a packet from device a to device B, and there are 2 labels for a packet from device B to device a. the Label is divided into an incoming Label and an outgoing Label, and assuming that the Label (incoming Label) of a packet entering device a is 0x0000, the Label (outgoing Label) of the packet leaving device a may become 0x 0001.
As shown in the following table, the data packet of the metro network mainly includes the following parts:
| DA | SA | Reserved | label (R) | Payload | CRC |
Namely Destination Address (DA), Source Address (SA), Reserved byte (Reserved), tag, payload (pdu), CRC. The format of the tag may be defined by reference to the following: the tag is 32 bits with the upper 16 bits reserved and only the lower 16 bits used, and its position is between the reserved bytes and payload of the packet.
The embodiments in the present specification are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments are referred to each other.
Furthermore, the present invention may take the form of a computer program product embodied on or more computer-usable storage media (including but not limited to disk storage, CD-ROM, optical storage, etc.) having computer-usable program code embodied therein.
It is to be understood that each flow and/or block in the flow diagrams and/or block diagrams, and combinations of flows and/or blocks in the flow diagrams and/or block diagrams, can be implemented by computer program instructions which can be provided to a processor of a general purpose computer, special purpose computer, embedded processor, or other programmable data processing terminal to produce a machine, such that the instructions, which execute via the processor of the computer or other programmable data processing terminal, create means for implementing the functions specified in the flow diagram flow or flows and/or block diagram block or blocks.
These computer program instructions may also be stored in a computer-readable memory that can direct a computer or other programmable data processing terminal to function in a particular manner, such that the instructions stored in the computer-readable memory produce an article of manufacture including instruction means which implement the function specified in the flowchart flow or flows and/or block diagram block or blocks.
These computer program instructions may also be loaded onto a computer or other programmable data processing terminal to cause a series of operational steps to be performed on the computer or other programmable terminal to produce a computer implemented process such that the instructions which execute on the computer or other programmable terminal provide steps for implementing the functions specified in the flowchart flow or flows and/or block diagram block or blocks.
Having thus described the preferred embodiments of the present invention, additional variations and modifications of these embodiments may occur to those skilled in the art from the basic inventive concepts .
Finally, it should also be noted that, in this document, relational terms such as , second, and the like are only used to distinguish entities or operations from another entities or operations, without necessarily requiring or implying any actual relationship or order between such entities or operations, furthermore, the terms "comprise", "include", or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or terminal that comprises the family of elements does not include only those elements but also other elements not expressly listed or inherent to such process, method, article, or terminal.
The theme switching methods, theme switching devices and computer-readable storage media provided by the present invention are described in detail, and specific examples are applied herein to describe the principles and embodiments of the present invention, and the above description of the embodiments is only used to help understand the methods and the core ideas of the present invention, meanwhile, for persons in the art, there are changes in the specific embodiments and application ranges according to the ideas of the present invention, and in conclusion, the present description should not be construed as limiting the present invention.
