However, the metro network address of the metro network device is unique, and in order to accurately describe the connection relationship between the metro network devices, parameters are introduced in the embodiment of the present invention: a label to uniquely describe a metropolitan area network device.
In this specification, the definition of the label is similar to that of a label of MP L S (Multi-Protocol L abel 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.
