Discuss bag, 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 with destination address (DA)；
Reserve bytes are made of 2 bytes；
Payload parts have different length according to the type of different datagrams, if being if various protocol packages
64 bytes, if single group unicast packets words be 32+1024=1056 byte, be not restricted to certainly more than 2 kinds；
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 slave device A to equipment B just
There are 2 labels, data packet slave device B to device A also there are 2 labels.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 consulted 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 form of label may be referred to be defined as below：Label is 32bit, wherein high 16bit retains, only with low 16bit, its position
Put 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, it then follows regarding the association of networking
View, is parsed by the network data received depending on networking protocol, and extraction obtains audio, video data, is finally based on the described of extraction
The multimedia file of code stream specified format is specified in video/audio generation.
Reference Fig. 5 shows a kind of step flow chart of code stream recording method embodiment based on regarding networking of the present invention,
The method specifically may include steps of：
Step 501, by regarding networking protocol receiving network data.
In working application, such as during video conference is carried out, audio, video data can be generated on depending on networked terminals,
The audio, video data of these generations needs, by being transmitted to regarding networked server depending on networking protocol, to complete in depending on networked server
Multimedia recording.
Step 502, the network data is parsed, extracts video/audio.
In a kind of preferable example of the embodiment of the present invention, networking protocol is regarded based on described, the network data is parsed, carries
Take video/audio.
Have depending on networking protocol different from TCP/IP (Transmission Control Protocol/Internet
Protocol, transmission control protocol/Internet Protocol also known as network communication protocol) protocol rule.So based on TCP/
The data of IP agreement can not be transmitted in depending on networking.
The network data is used is encrypted transmission depending on networking protocol, so need by being parsed depending on networking protocol,
Therefrom extract desired audio, video data.
