12 and service server 13, accelerate client 11 and accelerate to be communicated by network between service end 12.
The flow process of above-mentioned Operational Visit method as shown in Figure 2 a, specifically includes:
S20: terminal sends the first access request message to accelerating client, and the first access request message is used for
Request access service server.
When user's Operational Visit to be carried out, web page address to be accessed can be inputted in the terminal, in terminal
The first access request message can be generated, the IP of service server can be carried in the first access request message
Address identifies and conducts interviews service server.
First access request message can be HTML (Hypertext Markup Language) (Hyper Text Transport Protocol,
HTTP) message etc..
S21: accelerate to be transmitted to accelerate service after client receives the first access request message that terminal sends
End.
S22: accelerate to be transmitted to service server after service end receives the first access request message.
After S23: service server receives the first access request, carry webpage letter to accelerating service end transmission
First access response message of breath.
First access response message can also be HTTP message etc..
S24: after acceleration service end receives the first access response message, consults single biography with accelerating client
The data block size of transmission of data.
Accelerate after server receives the first access response message, in order to ensure under current ink quality
Good laser propagation effect, first with the data block size accelerating client negotiation single transmission data.
S25: accelerating service end and send the first data message to acceleration client successively, the first data message is
The info web accelerating to carry in the first access response message that service server is sent by service end is to consult
Data block size split after obtain.
S26: accelerate client and receive successively and accelerate the first data message that service end sends until determining the
One link is abnormal, sends redirection message to terminal, and the first link is the chain between terminal and service server
Road.
After accelerating the first data message that client receives acceleration service end transmission every time, will judge
Link-quality, if link is abnormal it is necessary to send redirection message to terminal, instruction terminal again accesses and adds
Speed service end carries out Operational Visit.
S27: after terminal receives redirection message, sends the second access request message to accelerating client,
Second access request message is used for asking to access accelerating service end.
S28: accelerate to be transmitted to accelerate service end after client receives the second access request message.
S29: after acceleration service end receives the second access request message, consults single with acceleration client again

Accelerate service end and can preserve the info web of compression, the first link exception when, it is possible to subtract
Data transfer size that is little and that accelerate between client, it is ensured that quickly return info web to terminal.
The info web of compression only retains content of text, after former webpage is modified, deletes or shields, adds
Speed service end can regenerate the info web of compression according to the renewal time of info web.
It is concrete it may be that accelerate after service end receives the first access response message that service server returns,
Whether webpage is judged according to the last modification time field (Last-Modified) in the first access response message
There is renewal, if it has, then need to update the info web of the compression of local preservation, the webpage that scanning receives
The html code of information, extraction hyperlink URL (Uniform Resource Location,
URL) with concrete web object file storing.
When need to accelerate client send compression info web time, it is possible to by compression info web with
The data block size renegotiated splits, and is then encapsulated in the second data message, is sent to accelerate visitor
Family end.
S31: accelerate client and receive the second data message accelerating service end transmission successively, by receive
Second data message be spliced into compression after info web after be sent to terminal.
In the program, terminal is during carrying out Operational Visit, and accelerating client can be with monitor terminal and industry
The quality of the first link between business server, after determining the first link exception, accelerates client permissible
Sending redirection message to terminal, terminal is according to redirection message, and request accesses accelerates service end, then adds
Speed service end can be to accelerating the info web that client push is compressed, owing to the info web ratio of compression is original
Info web much smaller, so terminal can quickly receive, it is ensured that user carries out the speed of Operational Visit
Degree and treatment effeciency.
Specifically introduce above-mentioned steps from accelerating client-side below:
Concrete, the acceleration client in above-mentioned S24 and the data accelerating service end negotiation single transmission data

Receiving and accelerate the negotiation packet that service end sends, negotiation packet is to accelerate service end by the first access request
Message sends after being transmitted to service server and receiving the first access response message；
The preset data block size corresponding with the first link is carried in response as the data block size consulted
Message is sent to accelerate service end.
Accelerate client and be connected adaptation stream (Link Adaptation with accelerating can use between service end
Stream, LAS) host-host protocol, receive and accelerate the negotiation packet that service end sends, be specifically as follows LAS
Control frame (SYN_STREAM), by LAS control frame and the number accelerating client negotiation transmission data
According to block size.
Accelerating client can be with maintenance link status information table, when accelerating the multiple link of client maintenance, and can
To determine the preset data block size corresponding with each link according to the information of record in link-state information table,
Link-state information tableau format is as follows:
Link identification: by the Internet protocol (Internet Protocol, IP) of terminal and service server
Location identifies link.
Preset data block size: default value is 64KB, according to the change of link-quality in transmission data procedures
Change trend updates.
Accelerating client can be according to the preset data block corresponding with link of record in link-state information table
Size is sent to accelerate service end by response message, and response message can be LAS control frame
(SYN_REPLY)。
Above-mentioned first data message and the second data message can be LAS Frames
(DATA_STREAM)。
Concrete, before receiving successively in above-mentioned S26 accelerates the first data message that service end sends, also
Including:
Receiving and accelerate the benchmark two-way time that service end sends, benchmark is to accelerate service end to send association two-way time
Business's literary composition is to the duration received between response message.
Assume that accelerating service end to the moment of acceleration client transmission negotiation packet is T0, accelerates service termination
The moment receiving response message is T1, then this duration of T1-T0 can serve as benchmark two-way time,
It is designated as RTT.
Receiving successively in above-mentioned S26 accelerates the first data message of service end transmission until determining the first chain
Road is abnormal, specifically includes:
After receiving the first data message, calculate the average deviation of transmission time every time；
According to the mass change trend judging benchmark two-way time and average deviation the first link；
Mass change trend according to the first link judged updates the preset data corresponding with the first link
Block size, if the preset data block size after Geng Xining is less than threshold value, then determines the first link abnormal.
After acceleration client receives the first data message every time, it is also possible to calculate and transmit the flat of time
All deviations MD,Wherein Tn is the n-th the first data messages received
Time, T (n-1) is the time of (n-1) individual first data message received.
It is assured that out the mass change trend of the first link according to the relation between MD and RTT, enters one
Step can update the preset data block size corresponding with the first link, and big according to the preset data block after updating
The quality of little judgement the first link.
Wherein, threshold value namely triggers the minimum data block size of the info web sending compression, Ke Yishe
It is set to 1Kbyte, it is meant that if the preset data block size after Geng Xining is less than or equal to 1Kbyte, then touch
Sending the info web of compression, certain threshold value can also be set to other numerical value according to practical situation.
Accelerate client and can safeguard flow state information table, when accelerating the multiple link of client maintenance, permissible
The benchmark two-way time of each link recorded in flow state information table and average deviation, flow state information table
Form as follows:

Time calculate, record in stream mode table.
Average deviation: every time after transmission data block, the average deviation of the transmission time of calculating.
Concrete, above-mentioned according to judging benchmark two-way time and average deviation that the mass change of the first link becomes
Gesture, specifically includes:
If average deviation is more than the benchmark two-way time of the first setting multiple, it is determined that the quality of the first link has
The trend being deteriorated；
If average deviation is less than or equal to the benchmark two-way time of the 4th setting multiple, it is determined that the matter of the first link
Amount has the trend improved, and the 4th sets multiple less than or equal to the first setting multiple.
Mass change trend according to the first link judged updates the preset data corresponding with the first link
Block size, specifically includes:
If the quality of the first link has the trend improved, the preset data block size corresponding with the first link is increased
Add the second setting multiple；
If the quality of the first link has the trend of variation, the preset data block size corresponding with the first link is removed
Multiple is set with the 3rd.
When the quality of the first link has the trend improved, this means that the network bandwidth is sufficient, can increase
The preset data block size corresponding with terminal, say, that the data block that can increase transmission data every time is big
Little；Otherwise, in order to avoid network congestion, the preset data block size corresponding with the first link can be reduced,
That is the data block size every time transmitting data can be reduced.Citing below illustrates:
Start---> Stream_size=8Kbyte；
After 1 RTT---> Stream_size=2*8Kbyte；
After 2 RTT---> Stream_size=3*8Kbyte；
After 3 RTT---> Stream_size=4*8Kbyte；
Assume that n-th link quality has the trend of variation---> Stream_size=
(n-1)*8Kbyte/2。
Wherein, first set multiple, second set multiple, the 3rd set multiple, the 4th set multiple permissible
It is set according to actual needs.Such as: 1,2,3 etc..
Optionally, after receiving successively in above-mentioned S31 accelerates the second data message that service end sends, also
Including:
Receive after accelerating the second data message that service end sends every time, rejudge the quality of the first link
Variation tendency；
Mass change trend according to the first link judged updates the preset data corresponding with the first link
Block size.
Accelerate client after receiving the second data message accelerating service end transmission, it is also possible to again every time
Judge the mass change trend of the first link, and according to the variation tendency of the quality of the first link judged more
The size of the new preset data block corresponding with the first link, thus consult single biography follow-up with acceleration service end
