Based on the above-mentioned characteristic of view networking, one of core idea of the embodiment of the present application is proposed, it then follows regard the association of networkingView, for same view networked clients, after receiving n-th data packet, using the first time threshold as the period, periodicallyGround detects whether to receive the N+1 data packet for carrying same identification marking, first carries out time-out record judgement, after just carry outJudgement is disconnected, can both disconnect in time connection when this is out of touch depending on networked clients in this way, discharges serverSystem pressure also can avoid causing to judge by accident depending on networked clients to this, cause to repeat to connect with this depending on networked clients to influence numberAccording to efficiency of transmission.
Embodiment 1:
As shown in figure 5, showing a kind of networking schematic diagram of the system of data timeout treatment of the embodiment of the present application, the systemSystem can be applied in view networking, and the view networking includes view networked server 01, be based on view with the view networked server 01Multiple view networked clients 02 of networking protocol connection.
It also can be considered the distributed data base frame based on view networking depending on networked server 01 mentioned by the embodiment of the present applicationFrame is distributed in each region of entire view networking, at most can access 255 view networked servers 01 in entire view networking.Each multiple view networked clients 02 that oneself place view intranet zone is managed depending on networked server 01, for example, view networking clothesCan be safeguarded in business device 01 it is managed enter netlist depending on networked clients 02, enter to have recorded in netlist and regard networked clients 02Number, title, addressable address etc. only carry out control tune depending on networked clients 02 to configured networking depending on networked server 01Degree.
It can be considered a kind of view networked hosts depending on networked clients 02, this can be an integrated view networking sound depending on networked hostsFrequently, the hardware and software device of the functions such as decoding video stream；It is also possible to a kind of data communication for supporting double nets (depending on networking, internet)Hardware and software device.Networking being regarded by view networking number access depending on networked terminals, (view in affiliated view networking network, which is networked, to be takenBusiness device 01), it is communicated with others depending on networked hosts etc..
Embodiment 2:
As shown in fig. 6, showing a kind of step flow chart of the method for data timeout treatment of the embodiment of the present application, the sideMethod can be applied in view networking, specifically can be applied in view networked server 01 shown in fig. 5, and the method specifically can be withThe following steps are included:
Step S601: the view networked server successively receives N number of data packet that view networked clients are sent；Wherein, N isPositive integer, the data packet carry the identification marking of the view networked clients；
Data mentioned by the embodiment of the present application, which can be, gives birth to depending on networked clients 02 according to the trigger action receivedAt, it is also possible to the data in other sources of forwarding.
Such as, in a kind of alternative embodiment of the application, provide a kind of data source mode, it is described depending on networking further include withThe first database 03 that the view networked clients 02 of network area where itself connect, the method specifically can also include followingStep:
N number of data packet is by the first database 03 generation when receiving the trigger action of data update；It is describedFirst database 03 is used to N number of data packet being sent to the view networked clients 02.Above-mentioned first database 03 can be withFor the MySQL database being connect with depending on networked clients 02.
It is described to be used to send out the data packet depending on networked clients 02 since above-mentioned first database 03 is located in internetBefore giving view networked server 01, the method is specifically further comprising the steps of:
It is described to be used to receive the internet that 03 internet protocol-based of first database is sent depending on networked clients 02Data packet；
It is described to be used to be based on depending on networked clients 02 that the internet data packet to be converted to view networking number depending on networking protocolAccording to packet.
Above-mentioned internet data packet is converted to the process of view networking data packet specifically: first disassembles packet header of data packet and interiorHold, the Internet protocol in packet header is removed, then will be added in packet header depending on networking protocol, and the data packet is sealed againDress, so as to form view networking data packet.
According to the level of current view networking, a view networked server 01 about can access 60000 view networked clients02, so view networked clients 02 are when sending data packet to view networked server 01, each data packet can carry describedDepending on the identification marking of networked clients 02, in order to identify depending on networked server 01 to received data packet, number is recordedAccording to source.Above-mentioned identification marking can be the MAC Address of view networked clients 02 or the account of view networking registration user.
In addition, since the transmission of data is propagated in the form of data flow after resolving into multiple data packets, so the applicationData packet in embodiment is preferably standard view networking data packet, and the standard regards networking data packet as 1024 bytes, with compared withThe transmission resolution speed of good adaptation view networking.
Step S602: it is described depending on networked server when receiving n-th data packet, record the n-th data packetIt stabs at the first time；
Due to being that data packet is sent to view networked server one by one in the form of data flow depending on networked clients 0201, the view networked server 01 and one by one received data packet, so just being recorded when often receiving a data packetThe receiving time of the data packet is stabbed.
Step S603: the view networked server judges the time difference of current time stamp and first time stamp；
Step S604: if the time difference is greater than preset first time threshold, the view networked server is with instituteStating first time threshold is the period, periodically detects and whether receives the N+1 data packet for carrying same identification marking；
Step S605: the view networked server is for detection every time, when not receiving the N+1 data packet,View networked clients corresponding with the identification marking are subjected to primary time-out record；
Step S606: when for it is described view networked clients time-out record number be greater than preset times threshold value or it is described whenBetween difference be greater than preset second time threshold, it is described to be disconnected with described depending on networked clients depending on networked server.
It is provided with overtime judgment module in depending on networked server 01, there is a timer in overtime judgment module, this is fixedWhen device/timer run as normal clock, show current time stamp all the time.
Due to being likely to be received the data packet that multiple view networked clients 02 are sent in synchronization depending on networked server 01,So by identification marking it may determine that the data source of the data packet.For same view networked clients 02, taken depending on networkingBusiness device 01 just stabs the receiving time of the data packet after N (N may be 1,2,3 ... N) a data packet for receiving its transmission(stab at the first time) is recorded, at the same calculate the time difference between current time stamp and at the first time stamp (can be regarded as fromStamp starts at the first time, and timer timing since 0, the time is longer, and the numerical value of timing is bigger on timer, i.e. time differenceAlso bigger), judge whether the time difference is greater than preset first time threshold and (can record once, or increase for timer is everyAs soon as adding numerical value, time difference and preset first time threshold judge primary), if difference has been more than presetTimeout interval (first time threshold), and do not receive the N+1 data packet of view networked clients transmission also at this time,Just it is believed that time out event has occurred, corresponding with the identification marking primary time-out record will be carried out depending on networked clients 02,Tentatively it is judged as that the view networked clients 02 are in data transmission unstable state.
Next, timer still lasting timing (i.e. since first time stab timing), then with described first whenBetween threshold value be the period, periodically detect and whether receive the N+1 data packet for carrying same identification marking.For example it is spacedA cycle does not receive the N+1 data packet, just carries out time-out for the first time to the view networked clients 02 and records；It is spaced second period, does not receive the N+1 data packet also, second of time-out just is carried out to the view networked clients 02Record ...
If being greater than preset times threshold value for the time-out record depending on networked clients 02 or the time difference being greater thanPreset second time threshold (second time threshold is much larger than first time threshold), then can determine that the view networked clients 02 are sent outRaw failure or network failure connected to it regard networked server 01 at this time and just actively disconnect and the view networked clients 02Connection, stop forwarding data to the view networked clients 02, and discharge the occupied resource of connection, current view can be relieved with thisThe pressure of networked server 01 is excessive, and system resource occupies excessively high problem.
For the step S603~step S606 of the embodiment of the present application, further illustrated using a specific example:
First time threshold is 2 seconds, and second time threshold is 30 seconds, and preset times threshold value is 16 times；
Regard networked server 01 receive the 1st data packet timestamp as 9:00, timer timing since 0 at this time, ifDetermine timer using the second as the unit of display, using millisecond as time of day, when timer is shown as 1.000 seconds, at this time and at the first timeThe time difference of stamp is 1 second, does not receive the 2nd data packet, time difference does not do any place again smaller than first time thresholdReason；When timer is shown as 2.000 seconds, it is at this time 2 seconds with the time difference of first time stamp, does not also receive the 2nd numberAccording to packet, time difference is equal to first time threshold, without any processing；But when the timer time is 2.001 seconds, at this time with theThe time difference of one timestamp is 2.001 seconds, does not also receive the 2nd data packet, and time difference is greater than first time threshold, willIt is corresponding with the identification marking to carry out primary time-out record depending on networked clients 02.Next, being taken at interval of two seconds depending on networkingWhether business device 01 receives the 2nd data packet under just detecting.When number of detection cycles is 15 times, i.e., join for the viewWhen the time-out record number of net client 01 is 15 times, the time difference has been 30 seconds at this time, so at 30.001 secondsWhen, it does not receive the 2nd data packet also at this time, will actively disconnect and connect with the view networked clients 02 depending on networked server 01It connects.
The embodiment of the present application is set as 1.5~3 seconds in an alternative embodiment, by first time threshold.It can avoid in this wayThe problem of timeout interval time sets too short, causes time-out record erroneous judgement depending on networked clients 02 to this；When also can avoid intervalBetween it is too long, to connect with depending on networked clients 02 network stabilization detection failure.
Meanwhile preset times threshold value is set as 16 times, the second time by the embodiment of the present application in another alternative embodimentThreshold value is set as 30 seconds~60 seconds.Threshold value setting is higher than 30 seconds, can preferably judge the net connecting with depending on networked clients 02Whether network is normal, avoids blindly disconnecting the connection with view networked clients 02；Threshold value is set lower than 60 seconds, avoids joining with the viewThe connection of net client 02 occupies the overlong time of view networked server 01, that is, avoids the system money for occupying view networked server 01The overlong time in source and running memory.
It is described depending on networking further include with second database 04 being connect depending on networked server 01, if regard the Internet servicesCommunication between device 01 and view networked clients 02 is normal, just forwards data packet after receiving data packet depending on networked server 01It is stored to the second database 04, in a preferred embodiment, specific pass-through mode can are as follows:
Step S607: it is described depending on networked server 01 when receiving n-th data packet, by the n-th data packet send outIt send into second database 04 and stores.
Above preferred embodiment shows a kind of mode of forwarding of data packet, is receiving one depending on networked server 01The data packet is just forwarded to the storage backup of the second database 04 when data packet, data packet can avoid with this and be deposited in view networking clothesIt is engaged in the interior the problem of occupying its memory of device 01, while can guarantee the integrality of data backup.Second database 03 is also to network with viewThe MySQL database that client 02 connects.
The embodiment of the present application elaborates data from the angle depending on networked server 01 by step S601~step S606A kind of possible mode of timeout treatment: being directed to same view networked clients 02, after receiving n-th data packet, with described theOne time threshold is the period, periodically detects and whether receives the N+1 data packet for carrying same identification marking, advancedRow time-out record judgement, after just turn off connection judgment, so both can be timely when the view networked clients 02 are out of touchConnection is disconnected, server system pressure is discharged, also can avoid that this is caused to judge by accident depending on networked clients 02, cause to repeatConnecting with this depending on networked clients 02 influences data transmission efficiency.
The data timeout treatment mechanism of the embodiment of the present application is different from traditional heartbeat inspecting mechanism, the embodiment of the present application withoutHeartbeat inspecting thread need to be individually established, heartbeat packet is sent or received or heartbeat frame to carry out heartbeat prison to view networked clients 02It surveys, heartbeat bag data can be reduced to the occupancy of the memory headroom of view networked server 01, reduce the operation of view networked server 01Pressure.
Meanwhile compared to traditional data transmission mechanism UDT, the data timeout treatment mechanism of the embodiment of the present application utilizes UDTPrinciple, not only overcome at present be not available UDT agreement view networking in transmit data the problem of, while also using view connectionThe data transmission security that the data transmission security of net compensates for UDT agreement is poor, is easy the problem of being stolen by others.
