Description
Technical field
The embodiment of the invention relates to communication technical field, specifically, relates to a kind of file transmitting method and dispensing device.
Background technology
Generic route encapsulation GRE (Generic Route Encapsulation) is a kind of layer 3 Tunnel protocol, this quasi-protocol has stipulated how to go to encapsulate with a kind of procotol the general mode of another procotol, and this tunnel encapsulation mode is adopted by a lot of access networks.Can adopt this packaged type in the R3/R4/R6 interface such as the WiMAX network.The WiMAX network mainly is made up of three parts, i.e. terminal (MS), access service network (ASN) and connection service network (CSN), and described access service network comprises base station (BS) and accessing business network gate (ASN-GW).Wherein, the communication interface between BS and the ASN-GW is referred to as the R6 interface, and the communication interface between ASN-GW and the CSN is referred to as Interface R3, and the communication interface between ASN and the ASN is referred to as Interface R4.
As shown in Figure 1, in the WiMAX network, adopting the GRE agreement to be encapsulated in Interface R3 is optionally, is essential at Interface R4 and R6 interface.The structure of GRE head comprises 4 fields referring to shown in Figure 2 in the structure:
1) control field: wherein the S position of control field is used for identifying whether carried Sequence Number;
2) protocol type field Protocol Type: protocol type indicated in the protocol type field can be
IPv4, IPv6, Ethernet, among the WiMAX Payload any one;
3) KEY: be used to identify Data Path ID;
4) sequence number Sequence Number: the sequence numbering of transmission payload, carry this in the data of transmission
The value of described control field is necessary for 1 during sequence number.
Whole GRE message comprises and is used to indicate the GRE heading of packaged payload relevant information and packed object GRE payload, wherein, the GRE head is 12 bytes to the maximum, for each interface that adopts the GRE agreement, arrive the message of any kind of corresponding interface, such as IPv4 message, IPv6 message, Ethernet message etc., all will transmit as the payload of GRE message.
IP-CS is an example with R6 interface IP convergence sub-layer, its host-host protocol model as shown in Figure 3, each IP message by R6 interface transmission (comprise from CSN and send to the message of ASN-GW and send to the message of ASN-GW from MS) all will be packed as the payload of GRE message, and then the GRE message be carried out after the encapsulation of IP, MAC and PHY and transmission.The encapsulation of the IP here is outer IP encapsulation, its IP address information addressing be the destination address of ASN-GW and BS.
Be example still with R6 interface IP-CS, for the smaller message of length by the transmission of R6 interface, such as the VoIP speech frame usually about 100 bytes, transmission will make expense very big (the expense actual size of each protocol layer encapsulation header can be with reference to figure 4 again after the R6 interface encapsulates, disregard the PHY expense of physical layer 20 bytes, then the encapsulation overhead of each bag is 50 bytes), and efficiency of transmission is very low, and (efficiency of transmission is defined as here: payload length/(payload length+encapsulation overhead)).And contain message below these a large amount of class 200 bytes in the real network usually, such as in the Internet network, the shared ratio of this class message probably is 40%～60%, and transmission will cause the average transmission efficient of whole network very low if all encapsulate again to this class message.The IP head of 20 bytes among Fig. 4 is the size substantially of IPv4 head, and after adopting the IPv6 agreement, this part expense will be bigger, and this moment, the size of IPv6 head was at least 40 bytes, will make that efficiency of transmission is lower.
