Comprising multiple redundant data packets, the quantity of specific redundant data packets is for example above-mentioned according to maximum transmission unit and data to be transmitted
The quantity of packet determines.
In one embodiment of the invention, when receiving layer protocol data and being converted into KCP data packet, due to data
The structure of packet changes, therefore when parsing to data packet, and specific analysis mode is also required to modify, modified solution
Analysis mode is as follows:
Step d1, parsing data take out order, and according to command analysis data packet, comprising:
If order is ACK (Acknowledgement confirms character), then judge whether remaining data length is greater than ACK
Packet header size is wrapped, remaining data length is greater than ACK packet packet header size if judging, parses data and takes out window size wnd, time
Stab ts, packet serial number sn, serial number una to be received；
If order is not ACK, window size wnd, timestamp ts, packet serial number sn, serial number una to be received, packet are parsed
Data length len, redundant data length rdc_len；
Step d2 adjusts kcp transmit queue according to una and adjusts kcp window；
Step d3, according to command analysis data packet, comprising:
Judge whether redundant data length rdc_len is greater than 0；
If rdc_len is greater than 0, Analysis design data packet；
Otherwise, this normal data packet is parsed.
The embodiment of the present invention introduced below applies a kind of realization in the data transmission of the fast and reliable agreement of game (KCP)
Method, particular content are as follows:
Strategy 1: redundancy number
When KCP sends data packet every time, N number of data packet being transmitted across before, the top n data packet promoted with this are carried
Transmission frequency.This N can be typically chosen 1 to 3 with dynamic select, be a configuration parameter；It is carried if should be noted that
It has been more than MTU (Maximum Transmission Unit, maximum transmission unit) after n-th redundant data packets, then just not
N-th redundant data packets can be carried, N-1 redundant data packets can only be carried.
Strategy 2: redundancy number
After a data coating is transmitted across certain number as redundant data packets, do not retransmit, to reduce flow
Waste.The number T is a configuration parameter.If a data coating is all lost as redundant data packets carrying T times, card
The state for comparing card has been arrived in bright game, and in this state, user has apparent perception, has received larger shadow
It rings；Meanwhile KCP itself has the mechanism of Fast retransmission, by timeout (time-out) and max ack (maximum retransmits) mechanism, this
A packet being dropped itself can be retransmitted certain number.It in the above-described state, can be meaningless to reduce by limitation redundancy number
Flow consumption.
Strategy 3: dynamic redundancy
When smaller due to network delay, the increase of packet loss does not have a significant impact two-way time, therefore increases dynamic
Redundancy strategy.Redundancy strategy is an option, can control whether to open by dynamic switch.Specific algorithm are as follows:
Defined parameters rdc_loss_limit, rdc_rtt_limit, rdc_close_tm, rdc_close_try, wherein
Remaining parameter is preset all in accordance with experience and experiment in addition to rdc_close_tm.Wherein, parameter rdc_loss_limit is pre-
If packet loss, rdc_rtt_limit is default two-way time, and rdc_close_tm is to be less than default two-way time two-way time
And/or packet loss is less than the number of default packet loss, rdc_close_try sets number.
A) rdc_close_tm=0 is set when initial
B) in each update cycle, if being currently at redundancy open state, and RTT is less than rdc_rtt_limit or loses
Packet rate is less than rdc_loss_limit, then adds 1 to rdc_close_tm, and if judging that rdc_close_tm is more than or equal to
Rdc_close_try closes redundancy；
C) in each update cycle, if being currently at redundancy closed state, and RTT is more than or equal to rdc_rtt_limit
And packet loss is more than or equal to rdc_loss_limit, then rdc_close_tm is set to 0, and open redundancy.
Strategy 4: unidirectional redundancy
Unidirectional redundancy refers to that the uplink/downlink redundant configuration of KCP will not influence the transmitting-receiving of the other end.To realize this spy
Property, it needs to modify to the packet header KCP, modification mode is as shown in Figure 2:
The part head refers to all packet header contents other than len and rdc_len, and len refers to the length of body,
Rdc_len refers to the length of rdc_body.Wherein rdc_body is made of rdc_data one by one, each rdc_data
Tri- parts rdc_sn, data_len and data are contained again.It, can be the case where not influencing other end transmitting-receiving under designing in this way
Under, the quantity of redundant data packets is carried by adjusting the rdc_data quantity for including in rdc_body adjustment.
The embodiment of the present invention is applied in game KCP protocol data transmission, under vulnerable network environment, after unlatching redundancy
Performance it is good, two-way time not will receive packet loss promoted bring influence.As shown in Figure 3, Figure 4, under vulnerable network environment,
Performance after unlatching redundancy is good, substantially in the environment of two-way time being greater than 100ms, not will receive packet loss elevator belt
The influence come, overall effect are lifted at 30%~40%.Meanwhile as two-way time and packet loss are continuously increased, above-mentioned strategy
Brought effect of optimization is also more and more obvious, and specific effect of optimization is as shown in Figure 5.
