Reserve bytes are made of 2 bytes；
The part payload has different length according to the type of different datagrams, is if it is various protocol packages
64 bytes are 32+1024=1056 bytes if it is single group unicast packets words, are not restricted to above 2 kinds certainly；
CRC is made of 4 bytes, and calculation method follows the Ethernet CRC algorithm of standard.
2.2 Metropolitan Area Network (MAN) packet definitions
The topology of Metropolitan Area Network (MAN) is pattern, may there is 2 kinds, connection even of more than two kinds, i.e. node switching between two equipment
It can all can exceed that 2 kinds between machine and node server, node switch and node switch, node switch and node server
Connection.But the metropolitan area net address of metropolitan area network equipment is uniquely, to close to accurately describe the connection between metropolitan area network equipment
System, introduces parameter in embodiments of the present invention: label, uniquely to describe a metropolitan area network equipment.
(Multi-Protocol Label Switch, multiprotocol label are handed over by the definition of label and MPLS in this specification
Change) label definition it is similar, it is assumed that between equipment A and equipment B there are two connection, then data packet from equipment A to equipment B just
There are 2 labels, data packet also there are 2 labels from equipment B to equipment A.Label is divided into label, outgoing label, it is assumed that data packet enters
The label (entering label) of equipment A is 0x0000, and the label (outgoing label) when this data packet leaves equipment A may reform into
0x0001.The networking process of Metropolitan Area Network (MAN) is to enter network process under centralized control, also means that address distribution, the label of Metropolitan Area Network (MAN)
Distribution be all to be dominated by metropolitan area server, node switch, node server be all passively execute, this point with
The label distribution of MPLS is different, and the distribution of the label of MPLS is the result that interchanger, server are negotiated mutually.
As shown in the table, the data packet of Metropolitan Area Network (MAN) mainly includes following sections:
| DA | SA | Reserved | Label | Payload | CRC |
That is destination address (DA), source address (SA), reserve bytes (Reserved), label, payload (PDU), CRC.Its
In, the format of label, which can refer to, such as gives a definition: label is 32bit, wherein high 16bit retains, only with low 16bit, its position
Set is between the reserve bytes and payload of data packet.
