Plug.
The problem of in order to solve congestion, when router R3 receives at least one upstream equipment such as router R12 and road
During the different types of message that at least one router is sent in device R22, the message flow speed to message is measured.For example
Server S 1 has two stream F13a (type of message RoCE, message flow speed 10kbps), F13b (type of messages to server S 3
TCP, message flow speed 20kbps)；There are 2 stream F23a (type of message RoCE, message flow speed from server S 2 to server S 3
100Kbps), F23b (type of message TCP, message flow speed 50kbps).Router R3 detect respectively F13a, F13b, F23a,
F23b message flow speed.
If step S102, different types of message message flow speed and more than preset flow rate rate, to it is described extremely
A few upstream equipment sends control information, and the control information is used to control at least one described upstream equipment to send inhomogeneity
The speed of type message.
If router R3 detects the message flow speed of F13a, F13b, F23a, F23b and more than preset flow rate rate,
The bandwidth of server S 3 is greater than, then to router R3 at least one upstream equipment such as router R12 and router R22
In at least one router send control information, the control information be used for control at least one in router R12 and router R22
Router sends the speed of different type message.Router R12 is received after the control information, continues to send to router R11
The control information, router R11 is received after the control information, continues to send the control information to server S 1, so as to control
Server S 1 sends the speed of message, for example, reduction server S 1 sends the speed of different types of message.Similarly, router
R22 is received after the control information, continues to send the control information to router R21, router R21 receives the control information
Afterwards, continue to send the control information to server S 2, so as to control server S 2 to send the speed of message, for example, reducing service
Device S2 sends the speed of different types of message.
Specifically, different types of message can be ranked up by router R3 according to message flow speed；According to the row
Sequence, determines that message flow speed is more than threshold value and type of message is the message of preset kind, and set to the upstream for sending the message
Preparation send the control information.
For example, router R3 is arranged according to the order of message flow speed from big to small F13a, F13b, F23a, F23b
Sequence, the result after sequence is F23a, F23b, F13b, F13a, it is seen that the main cause for causing the link congestion of server S 3 is clothes
It is engaged in caused by the message of device S3 transmissions, therefore, router R3 preferentially can send control information to router R22, to reduce road
By device R12 packet loss.
The present embodiment receives the different type that at least one upstream equipment is sent by the router between different server
Message, if different types of message message flow speed and more than preset flow rate rate, sent out at least one upstream equipment
Control information is sent, to control at least one upstream equipment to send the speed of different type message, so as to reduce network congestion.

In the present embodiment, when router R3 receives at least one upstream equipment such as router R12 and router R22
In at least one router send different types of message when, in addition it is also necessary to the message is detected, for example, detects the message
Source IP address, purpose IP address, type of message etc., and judge whether the message is ROCE messages according to type of message.It is optional
, the different types of message that router R3 sends at least one router in router R12 and router R22, which is stored in, to be cached
In.
If the length of buffer queue in step S304, the caching is beyond threshold value, dropping packets type is first pre-
If the message of type, retain the message that type of message is the second preset kind.
Optionally, the message of second preset kind is ROCE messages.When the length of buffer queue in caching beyond
Threshold value, then dropping packets type is TCP message, retains the message that type of message is ROCE, i.e. router R3 by F13a and
F23a message prior is sent, by F13b and F23b message random drop, to alleviate the situation of congestion.
If pre- to sending described second in addition, the flow of the message of second preset kind is beyond preset flow
If the upstream equipment of the message of type sends control information, the control information is used to controlling the upstream equipment to send described the
The speed of the message of two preset kinds.
When F13a and F23a flow exceedes the bandwidth of server S 3, then it is bound to occur packet loss.Such as server S 1, clothes
Device S2, the bandwidth of server S 3 of being engaged in are respectively 10G, when server S 1 and server S2 are sent with 6G speed to server S 3
During message, the congestion of server S 3 can be caused, according to the above method, server S 3 can select to abandon F13b and F23b report
Text, retains F13a and F23a message, but is due to that the message flow sum that server S 1 and server S2 are sent is 12G, surpasses
Go out the bandwidth of server S 3, in addition, the growth rate of server S 1 and server S2 transmission message flow is often quickly,
Often have little time as the jump step by step in preceding step to feed back transmission speed just reaches 6G.At this point it is possible to using big caching, by height
The message of priority such as ROCE messages (mainly RoCEv2) temporary cache gets off to avoid to abandon, while immediately to server S 1
Control information is sent with server S2, the control information is used to control server S 1 and server S2 to send the speed of message, example
The speed of ROCE messages is such as sent, soon to reduce transient congestion degree.
Specific method is：Router R3 once starts caching mechanism, then replaces server S 3 immediately to the kimonos of server S 1
Business device S2 sends control information, to control server S 1 and server S2 to send the speed of message.From router R3 to server
Router in S1 link, and the router from router R3 to server S in 2 link, once receive control letter
Then the very first time is transmitted to the router R11 and router R21 of server S 1 and server S2 connections to breath, when router R11 with
Router R21 mono- receives the message, sends Pause frames, device S1 out of service and service to server S 1 and server S2 immediately
Device S2 transmission, while the control information is transmitted into server S 1 and server S2, then cancels Pause frames recovery server S 1
With server S2 transmitting capacity.Further, control speed can also be included in the control information, the control speed is route
Device R3 controls server S 1 and server S2 to send the speed of message, and server S 1 and server S2 are received after the control speed,
According to less than or equal to the control speed message is sent to router R3.
If router R3, which detects certain first-class actual speed, is less than suggestion speed, while the speed phase of two stream
Plus less than the bandwidth of server S 3, then it is same to send cancellation suggestion speed message, return to normal transmission situation.If router
R3 generation congestion situations are excessively frequent, then can advise that user increases bandwidth.
The present embodiment abandons other kinds of message to alleviate network congestion by retaining ROCE messages, further realizes
ROCE flows without packet drop mechanism, improve the transmission reliability of ROCE messages.
