Accordingly, in order to solve the problem, the transmission control protocol of data center make use of emerging ecn (explicit congestion notification) (ECN) function in switch, it control strategy with data source is combined, thus ensure that the data of switch spatial cache occupy rate all the time lower than certain threshold value, as long as such short data stream is just queued up namely by switch substantially in this threshold value, ensure that the throughput of long data stream is higher, does not namely have too much abandoning simultaneously.
Further, for above-mentioned data center transmission control protocol, its realization mechanism is after some data messages queue to certain queue length, triggers ecn (explicit congestion notification), and then adjusts transmission rate by the control strategy of data source, therefore.Message still has queuing behavior, cannot realize ultralow Forwarding Delay.

Embodiment
Describe the present invention below with reference to embodiment shown in the drawings.But these execution modes do not limit the present invention, the structure that those of ordinary skill in the art makes according to these execution modes, method or conversion functionally are all included in protection scope of the present invention.
As shown in Figure 1, in one embodiment of the present invention, described message transmitting spped rate detection method, comprising:
For message to be sent arranges the virtual queue of a bypass.
In message repeating process, need rank in message passage, etc. to be forwarded, the application distinguishes the virtual queue of message channel setting one bypass, when message plan forwards, in the virtual queue of bypass, first carry out simulation queue up, judge the traffic forwarding state of message source mouth with this, below will describe in detail.
In an embodiment of the present invention, when message plan forwards from some outbound ports, message simulates repeating process in the virtual queue of described bypass.Concrete, message repeating time, described message is simulated queuing behavior extraly in described virtual queue, and records the virtual queue length counting of described message.
In present embodiment, can a virtual queue length counter be set in the virtual queue of bypass, for recording and upgrade the length variations of virtual queue.
Described virtual queue length counting can be the counting of message amount and/or the counting of message length.
When message plan forwards, the message that plan forwards sends at the inbound port of the virtual queue of bypass and produces request, and the roughly same time increases request to the outbound port initiation counting of the virtual queue of bypass, the described virtual queue length counting increase made.
In present embodiment, obtain the former virtual queue length counting of message source mouth, when message plan forwards, send the length counting of message according to plan, and former virtual queue length count update current virtual queue length counting; Current described virtual queue length counting after renewal=former virtual queue length counting+plan the length counting that E-Packets.
Further, scan cycle is set, virtual queue length counting described in timing scan, and reduces volume according to the single sweep operation pre-set, change described virtual queue length counting; After each scan period, the described virtual queue length counting=former virtual queue length counting-described single sweep operation after renewal reduces volume; If the virtual queue length after reducing is counted as negative, be then directly set to zero.
The described single sweep operation volume of reducing is the length counting that in default each scan period, message source mouth sends message.
In present embodiment, the scanner of a rated frequency can be set in the virtual queue of described bypass, according to virtual queue length counter described in designated period timing scan, after each scan period, reduce volume according to the single sweep operation pre-set, change described virtual queue length counting.
Further, according to virtual bandwidth assessment speed, and in the virtual queue scanning frequency calculating single scan period, the single sweep operation of virtual queue length reduces volume; The described single sweep operation volume of reducing=virtual bandwidth assessment speed/virtual queue scanning frequency.
In this example, enumerate an embodiment and elaborate.
Such as: assuming that the virtual bandwidth assessment speed of the virtual queue of bypass is 900Mbps, virtual queue scanning frequency is 4MHz, so, in the virtual queue of bypass, need the data volume by 900,000,000Kbit each second, namely 112,500,000 byte per second, and then, after each scanning, virtual queue length count ratio former virtual queue product degree counting minimizing 28.125 bytes of the virtual queue of described bypass.
In this example, during in order to make message repeating, the Forwarding Delay of message is minimum clog-free time delay, usually the bandwidth evaluation speed of the virtual bandwidth of the virtual queue of bypass assessment speed a little less than message passage is arranged, such as: described virtual bandwidth assessment speed is set to 90% of message bandwidth chahnel assessment speed.
S2, described virtual queue length counting and virtual queue excess threshold value to be compared; If described virtual queue length counting is greater than virtual queue excess threshold value, when judging described message repeating, described message outbound port is in excess and sends state.
Described excess threshold value, produces for judging whether a corresponding message amount counting and/or the message length counting that excess sends state for what preset in data switching exchane.
After each scan period, after message forwards from message source mouth,, message virtual queue length counting reduces thereupon, until when the virtual queue length counting of message is less than described excess threshold value, during the message repeating of decision plan, described message source mouth will be in normal discharge state, meanwhile, and the current state of the message notifying message source mouth that selectable plan of giving forwards, this current state comprises two kinds, and message source mouth is in normal forwarding state or sends state for excess.
In this example, message is when planning to send, and the queue length that E-Packets according to schedule increases the virtual queue length counting of the virtual queue of bypass; Meanwhile, arrange scan cycle, virtual queue length counting described in timing scan, and reduce volume according to the single sweep operation pre-set, successively decrease the virtual queue length counting upgrading described bypass.
So, assuming that current message transmit port is in normal transmission state.
If the transmission rate of message plan is less than 900Mbps, after each scan period, the virtual queue length counting of bypass reduces, the virtual queue length counting of described bypass will be less than excess all the time and send state excess threshold value, judge that described message passage is in normal discharge state by the virtual queue length counting of described bypass.Further, if after the whole messages in the virtual queue of bypass complete forwarding, also do not have next message to send, the virtual queue length counting of so described bypass will be kept to negative value, and is forced to be set to zero.
If the speed that message plan sends equals 900Mbps, after each scan period, if have message repeating in the virtual queue of described bypass always, the virtual queue length counting of bypass remains unchanged, the virtual queue length counting of described bypass will be less than described excess threshold value all the time, judge that described message passage is in normal discharge state by the virtual queue length counting of described bypass.Further, if after the whole messages in the virtual queue of bypass complete forwarding, next message is not also had to send, so, the virtual queue length counting of described bypass will reduce gradually, and finally can be kept to null value, certainly, because the scan period is asynchronous with message plan transmitting time point, the virtual queue length of bypass counting also may for leveling off to the positive number of null value.
If the speed that message plan sends is greater than 900Mbps, after each scan period, if before the message in the virtual queue of bypass completes forwarding, continue have new message to enter the virtual queue of described bypass, so, bypass virtual queue length counting will be always on the occasion of, and increasing along with message, described virtual queue length counting can increase gradually, when described virtual queue length counting is greater than described excess threshold value, when judging described message repeating, described message source mouth will be in excess and send state.
Further, if estimate described message source mouth will be in excess transmission state, excess can be sent state information and be sent to external treatment center.
In the present embodiment, described excess sends state information and can comprise: produce excess and send the transmit port information of state, produce the time information etc. of excess transmission state.
After described external treatment receive centre sends state information to excess; Because the flow in data center network is nearly all TCP flow amount, and the terminal equipment of these TCP flow amounts of all initiations all supports the protocol stack of DCTCP, therefore once there is excess to send status early warning, the TCP session of its correspondence reduces transmission data volume by regulations speed, thus the consumption reduced sending bandwidth, so for a link, provide network optimization scheme.
Further, transmitted by analog message in the virtual queue of bypass, and the bandwidth evaluation speed of the virtual bandwidth of the virtual queue of bypass assessment speed a little less than message passage is arranged, when being estimated message passage when message sends by the virtual queue length counting in the virtual queue of bypass and being in excess transmission state, transmission control protocol has just lowered transmission rate in advance when the bandwidth cost in the cycle of transmission has just been greater than transmission outlet link bandwidth, " slow turn-on " mechanism avoiding transmission control protocol causes link bandwidth to be occupied full, avoid the queuing started truly, so, eliminate the Forwarding Delay of queuing up and bringing, now, the Forwarding Delay of message only contains clog-free time delay part, and no longer include queuing part, the shake of its Forwarding Delay is also almost eliminated.
Shown in composition graphs 2, in the first execution mode of the present invention, described message transmitting spped rate checkout gear comprises: for message to be sent arranges the virtual queue of a bypass; Arrange in described virtual queue: Export resource counting module 100, flow monitoring module 200, excess send state reporting module 300.
Export resource counting module 100 for message repeating time, described message is simulated queuing behavior extraly in described virtual queue, and record described message virtual queue length counting.
In present embodiment, can a virtual queue length counter be set in Export resource counting module 100, for recording and upgrade the length variations of virtual queue.
Described virtual queue length counting can be the counting of message amount and/or the counting of message length.
Export resource counting module 100 for, when message plan forwards, the message that plan forwards sends at the inbound port of the virtual queue of bypass and produces request, and the roughly same time increases request to the outbound port initiation counting of the virtual queue of bypass, the described virtual queue length counting increase made.
In present embodiment, Export resource counting module 100 obtains the former virtual queue length counting of message source mouth, when message plan forwards, send the length counting of message according to plan, and former virtual queue length count update current virtual queue length counting; Current described virtual queue length counting after renewal=former virtual queue length counting+plan the length counting that E-Packets.
Further, Export resource counting module 100 arranges scan cycle, virtual queue length counting described in timing scan, and reduces volume according to the single sweep operation pre-set, and changes described virtual queue length counting; After each scan period, the described virtual queue length counting=former virtual queue length counting-described single sweep operation after renewal reduces volume; If the virtual queue length after reducing is counted as negative, be then directly set to zero.The described single sweep operation volume of reducing is the length counting that in default each scan period, message source mouth sends message.
In present embodiment, the scanner of a rated frequency can be set in Export resource counting module 100, according to virtual queue length counter described in designated period timing scan, after each scan period, reduce volume according to the single sweep operation pre-set, change described virtual queue length counting.
Further, Export resource counting module 100 is according to virtual bandwidth assessment speed, and in the virtual queue scanning frequency calculating single scan period, the single sweep operation of virtual queue length reduces volume; The described single sweep operation volume of reducing=virtual bandwidth assessment speed/virtual queue scanning frequency.
In this example, enumerate an embodiment and elaborate.
Such as: assuming that the virtual bandwidth assessment speed of the virtual queue of bypass is 900Mbps, virtual queue scanning frequency is 4MHz, so, in the virtual queue of bypass, need the data volume by 900,000,000Kbit each second, namely 112,500,000 byte per second, and then, after each scanning, virtual queue length count ratio former virtual queue product degree counting minimizing 28.125 bytes of the virtual queue of described bypass.
In this example, during in order to make message repeating, the Forwarding Delay of message is minimum clog-free time delay, usually the bandwidth evaluation speed of the virtual bandwidth of the virtual queue of bypass assessment speed a little less than message passage is arranged, such as: described virtual bandwidth assessment speed is set to 90% of message bandwidth chahnel assessment speed.
Flow monitoring module 200 is for comparing described virtual queue length counting and virtual queue excess threshold value; If described virtual queue length counting is greater than virtual queue excess threshold value, when judging described message repeating, described message outbound port is in excess and sends state.
Described excess threshold value, produces for judging whether a corresponding message amount counting and/or the message length counting that excess sends state for what preset in data switching exchane.
After each scan period, after message forwards from message source mouth,, message virtual queue length counting reduces thereupon, until when the virtual queue length counting of message is less than described excess threshold value, during the message repeating of decision plan, described message source mouth will be in normal discharge state, meanwhile, and the current state of the message notifying message source mouth that selectable plan of giving forwards, this current state comprises two kinds, and message source mouth is in normal forwarding state or sends state for excess.
In this example, message is when planning to send, and the queue length that E-Packets according to schedule increases the virtual queue length counting of the virtual queue of bypass; Meanwhile, arrange scan cycle, virtual queue length counting described in timing scan, and reduce volume according to the single sweep operation pre-set, successively decrease the virtual queue length counting upgrading described bypass.
So, assuming that current message transmit port is in normal transmission state.
If the transmission rate of message plan is less than 900Mbps, after each scan period, the virtual queue length counting of bypass reduces, the virtual queue length counting of described bypass will be less than excess all the time and send state excess threshold value, judge that described message passage is in normal discharge state by the virtual queue length counting of described bypass.Further, if after the whole messages in the virtual queue of bypass complete forwarding, also do not have next message to send, the virtual queue length counting of so described bypass will be kept to negative value, and is forced to be set to zero.
If the speed that message plan sends equals 900Mbps, after each scan period, if have message repeating in the virtual queue of described bypass always, the virtual queue length counting of bypass remains unchanged, the virtual queue length counting of described bypass will be less than described excess threshold value all the time, judge that described message passage is in normal discharge state by the virtual queue length counting of described bypass.Further, if after the whole messages in the virtual queue of bypass complete forwarding, next message is not also had to send, so, the virtual queue length counting of described bypass will reduce gradually, and finally can be kept to null value, certainly, because the scan period is asynchronous with message plan transmitting time point, the virtual queue length of bypass counting also may for leveling off to the positive number of null value.
If the speed that message plan sends is greater than 900Mbps, after each scan period, if before the message in the virtual queue of bypass completes forwarding, continue have new message to enter the virtual queue of described bypass, so, bypass virtual queue length counting will be always on the occasion of, and increasing along with message, described virtual queue length counting can increase gradually, when described virtual queue length counting is greater than described excess threshold value, when judging described message repeating, described message source mouth will be in excess and send state.
Further, if estimate described message source mouth will be in excess transmission state, excess can be sent state information by excess transmission state reporting module 300 and be sent to external treatment center.
In the present embodiment, described excess sends state information and can comprise: produce excess and send the transmit port information of state, produce the time information etc. of excess transmission state.
After described external treatment receive centre sends state information to excess; Because the flow in data center network is nearly all TCP flow amount, and the terminal equipment of these TCP flow amounts of all initiations all supports the protocol stack of DCTCP, therefore once there is excess to send status early warning, the TCP session of its correspondence reduces transmission data volume by regulations speed, thus the consumption reduced sending bandwidth, so for a link, provide network optimization scheme.
Further, transmitted by analog message in the virtual queue of bypass, and the bandwidth evaluation speed of the virtual bandwidth of the virtual queue of bypass assessment speed a little less than message passage is arranged, when when flow monitoring module 200 estimates message transmission by the virtual queue length counting in the virtual queue of bypass, message passage is in excess transmission state, transmission control protocol has just lowered transmission rate in advance when the bandwidth cost in the cycle of transmission has just been greater than transmission outlet link bandwidth, " slow turn-on " mechanism avoiding transmission control protocol causes link bandwidth to be occupied full, avoid the queuing started truly, so, eliminate the Forwarding Delay of queuing up and bringing, now, the Forwarding Delay of message only contains clog-free time delay part, and no longer include queuing part, the shake of its Forwarding Delay is also almost eliminated.
In sum, message transmitting spped rate detection method of the present invention and device, by arranging the virtual queue of bypass for message to be sent, and before message repeating, by the virtual queue of bypass, whether the transmit port estimating message passage in advance there will be excess sends state, the Forwarding Delay in real network is reduced to the Forwarding Delay under the clog-free condition of switch, accurately monitoring network operation conditions, meet becoming more meticulous of the security requirement that day by day improves in network and monitoring.
