Fill in message.
Wherein, base station is receiving packet (i.e. a 2nd UDP business number corresponding to the UDP business of server transmission
According to bag) after, the 2nd UDP business data packets are buffered in spatial cache；Then base station receives server transmission again
A packet (i.e. the first UDP business data packets) corresponding to UDP business, when spatial cache has been occupied full, (i.e. spatial cache delays
The size for the packet deposited is equal to or more than the size of spatial cache) when, base station then abandons the first UDP business data packets, and
Congestion messages are sent to server, congestion has occurred and that to cause server to know, so that server no longer passes through base station
UDP business datums or the UDP business datums of adjustment transmission are sent to client.
For example, it is assumed that UDP business is the video traffic that client 10 is initiated.Server 03 receives congestion messages and (known
Congestion has occurred and that) after, video data no longer is sent to base station 02, so that base station 02 does not also send video to client 10
Data；Or server 03 sends the video data of more low bit- rate to base station 02 so that base station is by the video data of more low bit- rate
Transmit to client 10.
Exemplary, purpose IP address and destination slogan letter can be included in the congestion messages in the embodiment of the present invention
Breath.For example, the UDP business that customer end A is initiated is UDP business 1, the server of customer end A is server A, and base station is to server A
Include the IP address and port number information of server A in the congestion messages of transmission.
Exemplary, the congestion messages in the embodiment of the present invention can be form as defined in agreement, such as base station can be to
Server sends the unreachable error message in ICMP ports, and congestion messages are carried in the unreachable error message in ICMP ports；Or
Person, the form of congestion messages can also be made an appointment by base station and server.
Certainly, when spatial cache is not occupied full, (i.e. the size of the packet of spatial cache caching is less than the big of spatial cache
It is small) when, the first UDP business data packets can be buffered in spatial cache by base station.Specifically, in the embodiment of the present invention, with reference to
Fig. 3, as shown in figure 5, above-mentioned S302 could alternatively be S501：
If S501, spatial cache are not occupied full, base station then caches the first UDP business data packets in spatial cache.
It should be noted that in the embodiment of the present invention, all UDP business configurations that base station can also be directed to terminal 01 are same
Individual spatial cache, to cache UDP business data packets corresponding to each UDP business of the terminal 01.
For example, the UDP business that the customer end A of terminal 01 is initiated is UDP business 1, the server of customer end A is server A,
The UDP business that the customer end B of terminal 01 is initiated is UDP business 2, and the server of customer end B is server B, and base station can be directed to
UDP business 1 and UDP business 2 configure a spatial cache, to cache UDP business data packets corresponding to UDP business 1 and UDP business
UDP business data packets corresponding to 2.
