Abstract
The invention discloses a binary system communication structure, and is applicable to a universal conference video software communication library. The binary system communication structure adopts binary coding, encapsulates the used bottom layer invoking and is used for communication among network terminal points. UDP messages are used for carrying communication messages, a heartbeat mechanism is used for guaranteeing the normal connection of networks, and an ACK response is used for ensuring a message loss retransmission function. Through adopting the mode, the binary system communication structure has the advantages that the software development efficiency can be improved, and the stability and the reliability are enhanced.
Description
Technical field
The present invention relates to a kind of general meeting audio frequency and video software communication storehouse, be applicable to the conference software of different system platform, for the intercommunication mutually between network endpoint.
Background technology
At the net environment based on TCP/IP, binary signaling structure can be used for the communication between terminal and server.Between the terminal and server of office under collaborative platform, and the communication between server do not mate, and causing cannot be general, communication pool that need to be different for the software development of different system platform.Think and adapt to different system platforms, need to set up an Overpassing Platform by Using storehouse and adopt general platform library technology, make can be in different system terminal and server software application.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of binary signaling structure, can improve software development efficiency, strengthens stability and reliability.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of binary signaling structure is provided, it is characterized in that: described binary signaling structure guarantees the network endpoint connecting with heartbeat mechanism, and remain contact, the mutual timed sending heartbeat message of communication pool end points connecting, reply after receiving heartbeat immediately opposite end, and after the former receives reply message, handle can judge that the other side is normal condition; When both sides' end points out of touch overtime after, both sides are interrupted to upper strata report contact;
Described binary signaling structure is guaranteed possible packet loss problem of UDP when communication by ACK acknowledgement mechanism, after every message is sent, all to wait for that opposite end returns to ACK message authentication and receive, if do not receive the ACK message of opposite end, retransmit original message, until receive ACK or overtime, if overtime, confirm that opposite end goes wrong or Network Abnormal, and report to upper strata;
Described binary signaling structure is used burst mechanism, excessive message is carried out to burst automatically, the message that is packaged into small pieces is sent, the communication pool of opposite end is according to the original message of automatically recombinating back of the sequence number on burst, report to upper layer software (applications), upper layer software (applications) can need not be concerned about this, only need messaging again, avoid the Bao Tai great of each UDP, and cause makeing mistakes in the middle of transmitting procedure;
The message that described binary signaling structure is received to upper strata software report by the mode of call back function, the exception reporting that binary signaling inside configuration produces also completes by the mode of call back function, each module of upper layer software (applications) can be by the call back function of oneself being concerned about to the registration of Overpassing Platform by Using storehouse, guarantee the message of receiving that oneself needs, to unwanted message, can not adjust back upper strata.
In a preferred embodiment of the present invention, described network endpoint comprises between terminal and server, between server and server.
The invention has the beneficial effects as follows: the present invention adopts UDP to carry out bearer messages, by heartbeat and ack mechanism, guarantee that automatic Sampling network is abnormal and lose the function of retransmitting; The details that binary signaling structure makes terminal and server no longer need consideration to communicate by letter, also without the different communication pool of the software development that is different system platform.
Embodiment
Below preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
The specific embodiment of the invention: upper layer software (applications) receives by registered callbacks function the message that receive in Overpassing Platform by Using storehouse, the connection of lower floor on Ethernet is responsible in Overpassing Platform by Using storehouse, in the present embodiment, with UDP message, carry out the message of two end points of bearer network.
The structural representation in the Overpassing Platform by Using storehouse that the present embodiment provides mainly comprises the compositions such as interface module, network process module, client transmissions module, service end transport module, Frame processing module, log management module.
The heartbeat request flow process in the Overpassing Platform by Using storehouse that the present embodiment provides is after Overpassing Platform by Using storehouse starts, and timer is also activated, and makes communication pool to send heartbeat message with identical interval by timed message.
The transmission message flow in the Overpassing Platform by Using storehouse that the present embodiment provides, Overpassing Platform by Using storehouse requires to initiate a message according to upper strata, and the message sending is counted and sent in history lists, and sending times and time-out count are set; After each timed message comes, check and send message history table, sending times is not 0 message, again retransmits and the sending times that successively decreases, the message that time-out count is 0, proceeds to timeout treatment.
The function that binary signaling structure of the present invention completes has: (1) has been responsible for the function about user management between terminal and server; (2) be responsible for account management function; (3) be responsible for the Conference Calling between terminal and server and controlled function; (4) be responsible for the chat feature between terminal; (5) described communication pool can, between the terminal and server at heterogeneous networks end points, be used heartbeat mechanism between server and server; (6) when using UDP as underlying protocol, by exploitation ack affirmation mechanism, communication pool is possessed and lose the function retransmitting, using under the expense that UDP is less like this, possessed the ability of reliable connection, can be applicable to different network environments; (7) use allocation methods to process oversize message, automatically carry out burst and recombination, met the requirement of transport network layer, simplified again the work for the treatment of of upper layer software (applications), make upper layer software (applications) without the details of being concerned about low layer.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
