payload(PDU)、CRC。
As shown in the table, the data packet for accessing net includes mainly following sections：
| DA | SA | Reserved | Payload | CRC |
Wherein：
Destination address (DA) is made of 8 bytes (byte), and first character section indicates type (such as the various associations of data packet
Discuss packet, multicast packet, unicast packet etc.), be up to 256 kinds of possibility, the second byte to the 6th byte is metropolitan area net address,
Seven, the 8th bytes are access net address；
Source address (SA) is also to be made of 8 bytes (byte), is defined identical as destination address (DA)；
Reserve bytes are made of 2 bytes；
The parts payload have different length according to the type of different datagrams, are 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 computational methods follow 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
2 kinds can be all can exceed that 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 unique, is closed to accurately describe the connection between metropolitan area network equipment
System, introduces parameter in embodiments of the present invention：Label uniquely describes 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 device A and equipment B there are two connection, then data packet from device A to equipment B just
There are 2 labels, data packet also there are 2 labels from equipment B to device A.Label is divided into label, outgoing label, it is assumed that data packet enters
The label (entering label) of device A is 0x0000, and the label (outgoing label) when this data packet leaves device A may reform into
0x0001.The networking flow 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 is all dominated by metropolitan area server, and node switch, node server are all passive execution, 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) includes mainly 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.
Based on the above-mentioned characteristic regarding networking, it is proposed that one of the core concepts of the embodiments of the present invention, using vod server
The method that the service on demand system constituted with storage gateway carries out file program request.
With reference to Fig. 5, a kind of step flow chart of file order method embodiment of the present invention is shown, be applied to program request and take
Business system, the service on demand system include vod server and storage gateway, can specifically include following steps：
Step 501, the vod server receives the instruction for regarding the program request file that networked terminals are sent.
In the present embodiment, the instruction of user's program request file is received depending on networked terminals, and program request instruction is sent to vod server.
Vod server receives the instruction for regarding the program request file that networked terminals are sent.Preferably, it can be equipped on depending on networked terminals
The application program of program request file, vod server receive the instruction of the program request file of the application program transmission of program request file.Program request
The application program of file can show at least one fileinfo such as mark, creation time, size of program request file, can also under
Loading point broadcasts file, and the embodiment of the present invention does not limit the concrete function of the application program of program request file in detail, can be according to reality
Border situation is configured.
Step 502, the vod server obtains base according to the instruction of the program request file from interconnection net storage device
