Description
Technical field
The present invention relates to reliable data transmission agreement in the digital communicating field, more particularly, relate to a kind of reliable data transmission agreement, be applicable to the system-level communication between plates that packet loss is lower based on tunnel, be a kind of reliably, data transfer mode efficiently.
Background technology
In open systems interconnection reference (OSI) model, data link layer is one deck between physical layer and network layer, and its purpose is exactly on physical link, data frame transfer to be arrived an other end, comprising transmission error processing, Flow Control processing etc.But data link layer is unreliable transport layer, and it can only guarantee the correctness of data, but can't guarantee reliable data transmission.So realize the reliable transmission of data, must have other agreements to guarantee.
In the reliable transmission technical scheme of system-level communication between plates, mainly contain following several kinds:
1)TCP
TCP can provide reliable data communication between the veneer for system.TCP is based on connection, is to need receiving terminal to send an affirmation in the transmission data, and it can handle IP message out of order and re-transmission simultaneously, and verification and flow control are provided.Through these modes, TCP provides a cover reliable transmission plan.
2)RDP
RDP agreement (RFC-908) is a kind of reliable transport protocol of simplification, and it is a kind of connection-oriented host-host protocol, and it mainly designs for the host monitor application program such as download is uploaded and effective bulk data transmission is carried out in remote debugging.RDP provides a full-duplex communication passage for each transport layer connectivity port, and it attempts reliable all user profile of sending, in case send failure, will be to the user report mistake.
3)UDT
UDT is a kind of host-host protocol of internet data.The main purpose of UDT is the mass data transfers of supporting on the high-speed wan, is built on the UDP, and has introduced and blocked control and data reliability controlling mechanism.UDT is connection-oriented two-way application layer protocol.It supports reliable data flow transmission and part datagram transmission reliably, simultaneously, also can be applied to other application, point-to-point technology (P2P) for example, and fire compartment wall penetrates, multi-medium data transmission or the like.
But there has been certain defective in agreements such as TCP, RDP, UDT:
(1) realizes complicacy
These agreements realize very complicated, need protocol stack.For the communication between plates of (such as HDLC) in the system that does not have protocol stacks such as TCP/IP, can't effectively support.
(2) need connection management mechanism
The veneer of system all can initialize communication interface after the startup, does not need to connect.If added connection mechanism, just need the administrative mechanism that connects again after the veneer exceptional reset is overlapped in realization one, this obviously is to have increased complexity for the communication between veneer.
(3) can't fictionalize a plurality of passages
Do not having in the system of TCP/IP, with HDLC communication, on same physical link, will realize a plurality of passages such as directly, current mechanism can't be supported a plurality of passages.
Summary of the invention
The objective of the invention is to solve problem set forth above, provide a kind of and can effectively solve data communication between veneer, be suitable for the reliable data transmission agreement based on tunnel of the data communication channel of all unreliable transmission.
Technical scheme of the present invention is such:
