Congestion avoidance algorithm relation table.
Table 3 congestion avoidance algorithm relation table
From table 3 it is observed that when region network characterization for band roomy, time delay is big, packet loss is high and
The bit error rate is high, can use westwood+ algorithm.When the network characterization in region be bandwidth little, time
Prolong stable and packet loss low etc., FastTCP algorithm can be used.When the network characterization in region is bandwidth
Greatly, time delay is little and packet loss is low, can use cubic algorithm.When the network characterization in region is that time delay becomes
Changing big, packet loss is random, can use hybla algorithm.Table 3 simply schematically illustrates, actual application
In can also include other congestion avoidance algorithm.
It should be noted that manager can pass through configuration file or application programming interface
(Application Programming Interface, API) is by zone information table, regional model table
It is configured to server with congestion avoidance algorithm relation table.Manager can also be according to the network characterization in region
Dynamic amendment congestion avoidance algorithm relation table, it is achieved the dynamic configuration of congestion avoidance algorithm relation table.
Congestion avoidance algorithm in congestion avoidance algorithm relation table is server global configuration and can make
Congestion avoidance algorithm.Corresponding relation in congestion avoidance algorithm relation table can be to provide congested control
The corresponding pass that the implementation suggestion that the provider of the congestion avoidance algorithm in algorithm relation table processed provides is set up
System, it is also possible to be to use different congestion avoidance algorithms and this congested control according to concrete network characterization
The algorithm parameter that algorithm processed is corresponding is repeatedly tested, and selects the congestion control of test best results to calculate
Method, the network characterization of foundation and the corresponding relation of congestion avoidance algorithm.
Server, according to described first network characteristic query congestion avoidance algorithm relation table, obtains described
The first congestion avoidance algorithm that one network characterization is corresponding, and the parameter of described first congestion avoidance algorithm
Value.
Server inquires about congestion control according to the network characterization of the market D of described regional identify code 4 correspondence
Algorithm relation table, the congestion avoidance algorithm obtaining the network characterization in described region corresponding is westwood+
And parameter γ=60 that westwood+ algorithm is corresponding.
Step 204, server are calculated according to described first congestion avoidance algorithm and described first congestion control
The parameter value of method, the client to a described corresponding region, IP address sends the first biography transport control protocol
View tcp data message.
Server is according to described congestion avoidance algorithm corresponding to described first network feature and described congested
The parameter value of control algolithm, initializes described congestion avoidance algorithm, to described client transmissions first
Tcp data message.If it should be noted that user end to server request data, described first
Tcp data message includes the data that client is asked.Or, client is not to server request number
According to, the first tcp data message includes the data that server sends simultaneously to multiple clients.
Assuming that user needs to access Sina's microblogging, it is micro-that the request that user end to server sends accesses Sina
Rich tcp data message, server is according to westwood+ corresponding to the network characterization in described region
Algorithm accesses the tcp data message of Sina's microblogging to the response of described client transmissions, and this response accesses
The tcp data message of Sina's microblogging includes that user needs the user data of Sina's microblogging.
Step 205, server receive the confirmation message that client sends.
At server according to congestion avoidance algorithm corresponding to described first network feature to described client
After transmitting the first tcp data message, client needs to send to server to confirm message (ACK).
Further, server monitors the network data of current transmission process in real time, such as, packet loss,
Time delay and bandwidth etc..Send tcp data message from server to client, receive visitor to server
Period between confirmation message ACK that family end sends is set to time delay.By server to client
Send the quantity of tcp data message, and server receives the quantity of the confirmation message that client sends
Difference, count the packet loss in transmitting procedure.Server can be according to the tcp data report of transmission
The byte quantity of literary composition and Delay, calculate the bandwidth situation of current transmission process.Perform step
206 or step 207.
Step 206, the second network characterization of a described IP address obtained when server are with described
During first network feature difference, by the corresponding relation between described IP network section and network characterization, institute
The network characterization stating the IP network section at a place, IP address corresponding is updated to described second network characterization.
Step 207, when the second network of the described IP address that server obtained in the second moment
When feature is different from described first network feature, by described IP network section, network characterization period and network
In corresponding relation between feature, the network characterization that the IP network section at a described place, IP address is corresponding
It is updated to described second network characterization.
Described first moment is different from described second moment, is engraved in described first network special when described second
Levy in the network characterization period of correspondence.
Further, when the unmatched number of times of network characterization is more than predetermined threshold value, a described IP
Network characterization corresponding to address is updated to described second network characterization, unmatched time of described network characterization
Count the number of times that the network characterization of the described IP address being acquisition is different from described first network feature,
Described predetermined threshold value is the network characterization of the described IP address obtained and described first network feature
Different preset times.
Particularly, if the client that server does not get to a corresponding region, IP address is sent out
The first congestion avoidance algorithm and described first congestion control required for sending the first tcp data message are calculated
The parameter value of method, server can use congestion avoidance algorithm and this congestion avoidance algorithm of global configuration
Parameter value.
