payload(PDU)、CRC。
As shown in the table, the data packet for accessing net mainly includes 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 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.
Based on the above-mentioned characteristic of view networking, one of the core concepts of the embodiments of the present invention is proposed, transmitting terminal is based at least
Two network interface cards establish at least two transmission channels with receiving end, the state parameter of current each network interface card are then obtained, according to each
The state parameter of network interface card distributes target data for each network interface card, wherein the state parameter of the data volume of target data and network interface card is just
Target data is sent to receiving end finally by the corresponding transmission channel of network interface card by correlation.
Referring to Fig. 5, a kind of step flow chart of data transmission method embodiment of the invention is shown, this method can answer
For being provided with the transmitting terminal of at least two network interface cards, this method can specifically include following steps:
Step 501 is based at least two network interface card, establishes at least two transmission channels with receiving end.
In the embodiment of the present invention, the network interface card number that is arranged on transmitting terminal can be to be arranged according to actual needs, it is preferred that hair
4 network interface cards have can be set in sending end.In specific implementation, multiple network card interfaces can be set on the mainboard of transmitting terminal, then
Each network card interface is connect with network interface card.
Further, transmitting terminal can be view networked terminals, and receiving end can be view networked server, certain receiving end
It can be view networked terminals, the embodiment of the present invention is not construed as limiting this.This can be set-top box (Set Top depending on networked terminals
Box, STB), commonly referred to as box on set-top box or machine is the equipment of connection a television set and outside source, it can will be pressed
The digital signal of contracting changes into television content, and shows on a television set.In general, set-top box can connect camera and
Microphone also can connect television set, for playing video counts for acquiring the multi-medium datas such as video data and audio data
According to the multi-medium datas such as audio data.It should be noted that first view networking is eventually in another alternative embodiment of the invention
End and target can also be mobile phone, computer, portable electronic device depending on networked terminals or incorporate the electricity of set-top box functionality
Depending on, etc., the embodiment of the present invention is not construed as limiting this.
Step 502, the state parameter for obtaining current each network interface card.
In the embodiment of the present invention, which can be signal strength, specifically, transmitting terminal can be by network interface card from net
