Specific embodiment
Ask to solve TCP traffic shunting mode of the prior art and cannot carrying out reasonable diffluence to business
Topic, the invention provides a kind of service shunting method and device, below in conjunction with accompanying drawing and embodiment, to this
Invention is further elaborated.It should be appreciated that specific embodiment described herein is only in order to explain
The present invention, does not limit the present invention.
Embodiment 1
Present embodiments provide a kind of service shunting method, the method is used for realizing dominant base in double-strand connection technology
Service distributing and prothetic group station between.
Due to business datum in prothetic group station handling process than the only more than once X2 of the handling process in dominant base
Transmission, in consideration of it, the RTT time-delay calculation that the present embodiment combines actual TCP traffic goes out X2 transmission introducing
Time delay, the impact to speed is judged according to additional time delay, in conjunction with main and auxiliary base station eat dishes without rice or wine gulp down
The amount of telling (theoretical throughput), carrys out the flow segmentation that main and auxiliary base station is carried out.
Because path keep-alive message packet is very simple, its group bag time can ignore, so path keep-alive please
(X2 is divided into two to connect to ask message to be X2-U from the time difference being sent to the response message receiving path keep-alive
Mouthful, one is used for control plane (X2-C), and one is used for user plane (X2-U)) loss on link
Time, if sending, window is constant, the speed of prothetic group station transmission data is affected to be V by X2-U links=W/
(Tr+TX2), the speed of dominant base transmission data is Vm=W/Tr, wherein, the communication of main and auxiliary base station is
No normal, guarantee to be sent according to the periodicity of path keep-alive message.TrFor RTT time delay, this RTT
Time delay represents from the beginning of transmitting terminal sends data, receives the time delay of the confirmation from receiving terminal to transmitting terminal.
Introduction in Transmission Control Protocol, the speed (V) of TCP traffic and transmission window length (W) and RTT time delay (Tr)
Between meet lower relation of plane V=W/Tr, W is that transmission window is long.Main and auxiliary base station is according to respective transmission data
Speed carries out data segmentation with reference to respective throughput distribution of eating dishes without rice or wine, and wherein, handling capacity of eating dishes without rice or wine is in full scheduling feelings
Under condition according to the standard of base station, proportioning and MCS (Modulation and Coding Scheme, modulation with
Coding strategy) calculated.
Understood according to above analysis, the factor of impact service distributing has handling capacity, time delay, actual gulp down if total
The amount of telling is TR it is assumed that dominant base handling capacity is TRm1, prothetic group station can handling capacity be TRs1, only considering
Specifically split in the case of time delay：
TRm=TR* (Vm)/(Vs+Vm)=TR* (Tr+TX2)/(2Tr+TX2)
TRs=TR* (Tr+TX2)/(2Tr+TX2)…………………………………(1)
In the case of only considering handling capacity, specifically split into：
TRm=TR*TRm1/(TRm1+TRs1)
TRs=TR*TRs1/(TRm1+TRs1)……………………………………(2)
However, because in actual applications, due to time delay, the impact to speed may be different with handling capacity, therefore
Actual environment can carry out weight distribution according to this impact to business for two factors of influence.As：The power of time delay
Account for P againv, the weight of handling capacity accounts for Pt, then, in the present embodiment following public affairs are shown according to both shunting result
Formula：
TRm=TR* (Pv*(Tr+TX2)/(2Tr+TX2)+Pt*TRm1/(TRm1+TRs1))
TRs=TR* (Pv*(Tr+TX2)/(2Tr+TX2)+Pt*TRs1/(TRm1+TRs1))……(3)
If both factors of influence are identical, that is, weight is equal, and shunting formula sees below
TRm=TR* ((Tr+TX2)/(2Tr+TX2)+TRm1/(TRm1+TRs1))/2
TRs=TR* ((Tr+TX2)/(2Tr+TX2)+TRs1/(TRm1+TRs1))/2..............(4)
If only considering handling capacity, shunt the same above-mentioned formula of result (2).
