Abstract
The invention discloses an MPTCP data scheduling method based on forecast arrival time. According to the method, after data packages are transmitted from an application layer, a dynamic RTT value is obtained according to current receiving package information, a real-time dynamic transmitting period is extracted according to the number of packages in a current network, the transmission time of the last data package and the receiving time of a last receiving package, in the end, the time of the data packages transmitted from each path to arrive at the receiving end is forecasted by comprehensive considering of the RTT value, the transmitting period and the number of the transmitted packages in a current path, and therefore the correct path is selected so as to achieve the purpose of receiving end sequential arrival. The MPTCP data scheduling method enables the RTT value and the transmitting period to be mixed together to obtain a dynamic smoothing parameter, and has the advantages of being capable of increasing the transmission rate and stabilizing the throughput capacity and suitable for being used in the aspect of data scheduling in the MPTCP transmission field.
Description
Technical field
The invention belongs to the MPTCP transmission field, specifically belong to, a kind of state and packet sending speed according to network link, the time of advent of prediction data bag is to carry out the method for data dispatch.
Technical background
In recent years, application development along with the Internet, and terminal equipment such as mobile phone, notebook can have a plurality of network interfaces that belong to different access networks simultaneously, yet conventional transmission control protocol (TCP) is man-to-man host-host protocol, do not take full advantage of the advantage of the many interfaces of multiple access of current network equipment, cause the wasting of resources.For this reason, Christian Huitema as far back as nineteen ninety-five at the draft(HUITEMA of IETF C., Multi-homed TCP draft-huitema-multi-homed-0[S] .IETF, 1995.) in MPTCP(multi-path transmission control protocol is proposed) thought, MPTCP is the improvement agreement of a kind of TCP, it allows a TCP connection to carry out the transmission of data simultaneously by mulitpath, and its protocol infrastructure is as shown in table 1.
Table 1
IETF(Internet Engineering Task Force, Internet engineering duty group) set up MPTCP working group specially in 2009, mainly be devoted to solve the problem of MPTCP architectural framework, congested control, route, API, secure context, but and assurance MPTCP back compatible tradition TCP.The proposition of MPTCP mainly contains two general objectives: 1. the bandwidth of many reachable paths of polymerization improves throughput, and total throughput of MPTCP is not less than the throughput of any paths between communication node; 2. the elastic recovery capability by providing mulitpath to improve integral body, and intelligent management flow.
In sum, the develop rapidly of multi-path transmission technology, but its comprehensive utilization ability to multipath is still waiting raising, and the transmission rate of especially right title multipath otherness is the subject matter of current multi-path transmission.
For individual paths, the flow-control mechanism of MPTCP is identical with TCP, and namely when the receive window of receiving terminal during less than the congestion window of transmitting terminal, the speed that transmitting terminal sends data is subjected to the influence of iSCSI receiving end window size, when the iSCSI receiving end window size was 0, transmitting terminal stopped to send data.In view of the MPTCP agreement is used mulitpath in transmission course, when there was bigger otherness in the performance between the path, the link of poor performance can make thereon that data packets for transmission can not in time arrive receiving terminal, thereby out of order problem occurs.Because it must be continuous that application layer receives the packet of handling, receiving terminal must be waited for the packet that corresponding sequence number is forward, makes window constantly reduce, thereby has suppressed the transmission rate of transmitting terminal, has reduced message transmission rate.
Find the data dispatch mechanism of the MPTCP agreement that has its source in of problem among the MPTCP adaptability problem in isomery path being analysed in depth the back.For addressing this problem, must be absorbed in the transmission path in transmitting terminal control data, make these data can be close to the arrival receiving terminal of order, the probability that reduce to retransmit, it is very necessary therefore setting up the variability issues that a kind of good packet scheduling strategy reduces the path.
Originally the packet scheduling scheme to the MPTCP transmitting terminal mainly is divided into two kinds: the one, by simple poll measure, will distribute to each path transmission at once from the data that application layer issues; The 2nd, the congested control window CWND according to each path is distributed to available path with data.Above-mentioned two kinds of measures are very simple, are easy to realize, but thoroughly do not solve congested and out of order problem.2011, in the RFC of MPTCP document, propose to use dual-serial number, i.e. sub-fluid layer sequence number and data Layer sequence number.Its neutron fluid layer sequence number namely is the sequence number among the traditional TCP, and the data Layer sequence number then is encapsulated in Option Field.Make receiving terminal after receiving packet, resequence according to mapping relations and sequence number by the technology of using mapping, but this scheme is just distinguished the bag of different paths transmission, do not have concrete implementation algorithm, at transmitting terminal packet is not carried out data dispatch yet, thereby determine at any strip stream to transmit, also do not solve the out of order problem of receiving terminal.
The realization of current MPTCP agreement is by the modification to the linux kernel code, the protocol of multi-path transmission is added in the network protocol stack of operating system, data dispatch is wherein only considered RTT (Round-Trip Time, round-trip delay), namely after receiving data from application layer, by the RTT sample value that extracts in never wrapping with the ACK that receives on the path, with the path of the minimum RTT wherein transmit path as current data packet, but it does not consider the available bandwidth in path and the transmission speed of transmitting terminal, make moment send a big segment data in the less path of RTT value, can not guarantee that it arrives receiving terminal in order smoothly.
Above several method does not have the out of order problem of solution receiving terminal truly, because they do not take all factors into consideration the transmission state of network transmission environment and current transmission layer.
Summary of the invention
Technical problem to be solved by this invention provides a kind of based on the prediction MPTCP data dispatching method of the time of advent, this method can be estimated the time of advent of current pre-transmission packet on different paths real-time dynamicly, and then realize the active data scheduling, to solve the out of order problem of receiving terminal.
