Transmission rate in addition to not catching up with data depending on networked clients or depending on processing speed of the networked server to data, leads
The problem of being forced packet discard depending on networked clients or depending on networked server is caused, in the data transmission mechanism of view networking at present also
Have the following problems: transmitting terminal sequentially persistently sends data packet to receiving end, and receiving end is to some data packet reception failure or right
When the processing overlong time of data, transmitting terminal can not receive the sound of receiving end within a certain period of time after having sent all data packets
Answer, will take for data transmission lose, and can by all data packets from start retransmit to receiving end so that receiving end
It is duplicate to receive excessive data packet, system resource is occupied, causes receiving end operation abnormal.
For example transmitting terminal is view networked clients, receiving end is view networked server, 10 numbers of transmitting terminal periodicity sending
View networked server is given according to packet, and arranges serial number the 5th data packet reception failure depending on networked server, can continue to wait Receiving Order
The 5th data packet number is arranged, and is still in the lasting state for sending data packet depending on networked clients, is being sent out depending on networked clients
It can not receive the response for regarding networked server within a certain period of time after having sent all data packets, data transmission will be takeed for and lost,
It can be sent again by all data packets (10 data packets) from starting to retransmit to networked server is regarded with maximum delivery formula,
Cause in this way depending on networked server it is duplicate have received excessive data packet (repeat Receive sequence number arrange 1~4,6~10 data
Packet), the system running pressure of server is increased, prevent system resource is from being used appropriately.
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 networking
View increases in the transmitting terminal (depending on networked clients or view networked server) of view networking and sends buffer queue, and receiving end is (depending on networking
Client or view networked server) increase reception buffer queue, data packet is first put into transmission before sending data by transmitting terminal
In buffer queue, data packet is first put into after receiving data packet and before handling data and receives in buffer queue by receiving end,
And the confirmation message feedback of the data packet will be received simultaneously to transmitting terminal, so that transmitting terminal is normally by next data packet from hair
It send and receiving end is taken out and be sent in buffer queue, the embodiment of the present application is using transmission buffer queue and receives buffer queue simultaneously
The mode of caching increases the time that data processing is arrived after data are transmitted, and is that receiving end processing data are reserved using the time
Cushion space can solve to regard networked clients or view the Internet services at present so that receiving end can handle data by its normal speed
Not the problem of device does not catch up with the transmission rate of data to the processing speed of data, leads to data packet packet loss, while can guarantee primary view
Stability and integrality of all data in transmission in networking service, is avoided that receiving end repeats to receive excessive data
Packet, increases own system operating pressure, prevent the problem of own system resource is from being used appropriately.
