Abstract
The invention provides a fast path response method and system. The method includes: after a receiving end receives the FSACK-INIT message transmitted by a transmitting end, all the ports of the receiving end transmits FSACK-ACK messages; when the transmitting end receives the first FSACK-ACK message, whether the unique identification in the response method and system is identical with the unique identification in the FSACK-INIT message or not is verified; if so, the transmitting end replies an FSACK-FINAL message to the receiving end from the path, receiving the first FSACK-ACK message, namely the target path; after the receiving end receives the FSACK-FINAL message, the receiving end transmits a selection confirmation message from the target path. By the method, the minimum-time-delay path is found from multiple paths fast, then all the SACK messages of the receiving end are transmitted through the path, and overall system throughput is increased.
Description
Technical field
The invention belongs to Path selection field, particularly relate to a kind of fast path answer method and system.
Background technology
Flow transmission control protocol (SCTP, Stream Control Transmission Protocol) is a kind of new transport layer protocol, likely replaces TCP in the future; SCTP is a kind of agreement acting on multiple port, but according to the up-to-date regulation of RFC, only uses a port to carry out transfer of data under default situations, will affect the advantage that SCTP plays multiport communication undoubtedly, so there is the SCTP of multipath transfer.
Multipath transfer (CMT, Concurrent Multi-path Transmission) streaming media control protocol be a kind of data transfer mode that more can adapt to multiport, this transmission means comparatively before algorithm and strategy also there is certain inadaptability, show redundant retransmission, too conservative congestion window upgrade and the aspect such as a large amount of SACK messages.
The people such as Iyengar propose new algorithm and strategy in these problems, wherein divide the problem that Fast retransmission algorithm (SFR, Split Fast Retransmission) solves redundant retransmission; New congestion window update algorithm (CUC, CWND Update for CMT) solves the problem that too conservative congestion window upgrades; Delayed response algorithm (DAC, Delay ACK) solves the problem of a large amount of SACK message.
SFR algorithm, CUC algorithm and DAC algorithm are all the transmitting terminals for transfer of data, but transfer of data needs the collaborate of both sides, due in default situations, select to confirm (SACK when data receiver needs to send, Selective ACK) message time, always select a nearest path receiving DATA data block, if the path delay of time of this paths is large or the congestion situation in path is bad, then certainly will have influence on the reception of data sending terminal to this message, thus affect the transmission of following data and then the throughput of impact entirety.
According to the design of current SCTP, always transmitting terminal occupies the initiative position, initiatively go time delay and the bandwidth of detective path, and determine the transfer of data transmission again of some messages (or before) of carrying out next message from any paths, when receiving terminal needs to send SACK data, acquiescence uses the path receiving packet for the last time; Receiving terminal is optimum transmit path owing to not understanding which paths, causes the transmission of SACK to be blindly, if SACK uses the path that time delay is larger to send, will have a strong impact on the overall performance of network.
Summary of the invention
The invention provides a kind of fast path answer method and system, to solve the problem.
The invention provides a kind of fast path answer method.Said method comprises the following steps:
After receiving terminal receives the FSACK-INIT message of transmitting terminal transmission, send FSACK-ACK message from described receiving terminal total interface;
After described transmitting terminal receives first described FSACK-ACK message, verify that whether the unique identifier in described FSACK-ACK message is identical with the unique identifier in described FSACK-INIT message;
If identical, then described transmitting terminal replys FSACK-FINAL message from first path receiving described FSACK-ACK message and destination path to described receiving terminal;
After described receiving terminal receives described FSACK-FINAL message, send from described destination path and select confirmation message.
The present invention also provides a kind of fast path answering system, comprises transmitting terminal, receiving terminal; Wherein, described transmitting terminal is connected with described receiving terminal;
Receiving terminal, after receiving FSACK-INIT message that transmitting terminal sends, sends FSACK-ACK message from total interface;
Described transmitting terminal, after receiving first described FSACK-ACK message, verifies that whether the unique identifier in described FSACK-ACK message is identical with the unique identifier in described FSACK-INIT message;
If identical, then reply FSACK-FINAL message from first path receiving described FSACK-ACK message and destination path to described receiving terminal;
Described receiving terminal, after receiving described FSACK-FINAL message, sends from described destination path and selects confirmation message.
Compared to prior art, according to a kind of fast path answer method provided by the invention and system, from mulitpath, can find out rapidly the path of minimal time delay, the SACK message that receiving terminal is all afterwards all sends from this paths, improves the throughput of entire system.
