Description
Technical field
The invention belongs to data processing field, particularly relate to and a kind ofly weigh server method and system to data-handling efficiency in TCP transmission.
Background technology
TCP/IP (Transmission Control Protocol/Internet Protocol) transmission control protocol/Internet protocol, have another name called network communication protocol, be the basis of the most basic agreement of Internet, Internet Internet, be made up of the IP agreement of network layer and the Transmission Control Protocol of transport layer.TCP/IP defines electronic equipment and how to be connected into internet, and the standard how data are transmitted between which.Agreement have employed the hierarchical structure of 4 layers, and the network that lower one deck that every one deck all calls out it provides is to complete the demand of oneself.Popular: TCP is responsible for the problem finding transmission, once there be problem just to send signal, require again to transmit, until all data securities are correctly transferred to destination.
TCP provides a kind of connection-oriented, reliable byte stream service.In order to realize reliable byte stream service, adding a lot of index of correlation in Transmission Control Protocol and helping realize this goal, as follows:
RTO (Retransmission TimeOut) i.e. retransmission time interval.Main frame is after transmission tcp data bag, if slowly do not receive ACK (Acknowledgement, i.e. acknowledge character, in data communication, receiving station issues the one transmission class control character of dispatching station, represent that the data sent have confirmed that reception is errorless), how long main frame can retransmit this packet afterwards.Main frame is from sending packet to first time TCP re-transmission, and interval is referred to as retransmission time interval during this period of time.
RTT (Round-Trip Time): round-trip delay.It is important performance index in a computer network, represents from transmitting terminal sends data, receives the confirmation (receiving terminal just sends confirmation after receiving data immediately) from receiving terminal, the time delay altogether experienced to transmitting terminal.
SW (Sliding window) sliding window: the size of the data that source host can transmit before receiving acknowledge message is called window size.For managing obliterated data and flow control.
Wherein, in current ICP/IP protocol, widely used two time delay indexs are RTT and RTO.And RTT is determined by three parts: i.e. queuing in the buffer memory of the propagation time of link, the processing time of end system and router and processing time, wherein, the value of two parts connects relatively fixing as a TCP above, queuing in the buffer memory of router and processing time can change, so the change of RTT reflects the change of network congestion degree to a certain extent along with the change of whole network congestion degree.RTO: time-out and very most important part in re-transmission are the measurements to the given two-way time (RTT) be connected, due to the change of network traffics, this time can correspondingly change, and TCP needs to follow the tracks of these changes and dynamic conditioning time-out time RTO.
There is following network condition in current existing network: when transmitting a certain size packet, RTT value be less, without retransmitting, individual data packet transmission rate comparatively fast, but overall service transmission rate is lower.For this kind of situation, infer in the industry it is likely home server (data sending terminal) transmission to packet and the treatment effeciency to ACK is lower causes, the index occurred in existing ICP/IP protocol is mainly used in the transmission problem of response data, and neither one index can react home server (data sending terminal) to the treatment effeciency of data flow.
Summary of the invention

Further, if the transmitting time of described two adjacent data bags stabs the processing time information included to the ACK message received between transmission twice adjacent data bag, then step 2 is specially:
The difference that the transmitting time of described two adjacent data bags is stabbed is deducted the value that the round-trip delay in TCP transmission obtains, then compare with the threshold values of the timestamp difference preset.
