With reference now to Fig. 1,, shows the embodiment of aggregate-rate service model 100.Service provider's network 110 provides aggregate-rate communication services to client 120.Client 120 is relevant with 7 ports, and promptly 7 port-for-ports 131 are visited service provider's network 110 to port one 37 with this.Committed rate G of these 7 ports share forms aggregation group.Service provider's network 110 can have arbitrary topology.Port in the aggregation group is shared the capacity of aggregation group liberally.
Can use the inlet rate of each port within the rate control algorithm control aggregation group, to guarantee meeting service-level agreement (SLA, Service Level Agreement) by the aggregate-rate services that service provider's network 110 provides.Each port is measured Ii during current period t.When period t finishes, port i, for example port one 31 can dispense rate message, and this message contains (and may through smoothing and/or filtering) the inlet rate value I through measuring
iAnd the sign of port i.
Each port within the aggregation group can receive the speed message by other port distributions in the aggregation group.For example the port of port one 37 receives the speed message from transmit port after being the D delay of second to the maximum.The inlet rate R that receives in the speed message that receiving port 137 is preserved from port i
iValue.
So each port can obtain the inlet rate information of every other port in the aggregation group, and, calculate the permission speed of next period with of the input of this information as rate control algorithm.Adopt rate control algorithm in the present embodiment, if the speed sum of all of the port in the aggregation group less than committed rate, is then carried out oblique ascension; If all of the port speed sum in the aggregation group is then regulated more than or equal to committed rate.
The speed management strategy can be provided the mode of the ports share aggregation group capacity that is used for specifying aggregation group, and the mode of the capacity requirement of each port in the management aggregation group.For example, the port relevant with aggregation group can be equably or shared the capacity of aggregation group in proportion according to weighting scheme, and permission speed that perhaps can a port is set to predetermined value or is restricted to the value that is greater than or less than predetermined value.Can use single speed and the rate of polymerization of rate control algorithm according to speed management strategy control aggregation group.
Rate control algorithm can change according to different speed management strategies.Port member that an embodiment of speed management strategy can be an aggregation group is fair but be not to share committed rate equably.For example, be that volume server and other ports are exactly this situation during for client at a port.It may be useful sharing committed rate but allow the greater share of server access committed rate.
Utilize this speed management strategy, in one embodiment, can distribute a weight factor, W for each port i
iAt through-rate message report inlet rate I
iThe time, by the value that will be reported divided by W
iReport value is carried out normalization.
So, for the local port that carries out oblique ascension, term B can be changed to W
LocalB so that adapt to weight factor, and can change to the permission speed of next period:
A
local＝I
local+W
localB。
That is, can with during period t with speed I
iThe port i that sends is restricted to A during period t+1
i=I
i+ W
iB.Do not having under the situation about postponing, this ramping method can be guaranteed ∑ I during period t+1
i≤ G+ ∑ W
iB because in period t ∑ I
i≤ G, each port can be no more than W with its inlet rate increase
iB.
Existing under the situation that postpones D, enough overhead provisions must be arranged, so that the delay of reply speed message arrives.In time durations D, the inlet rate of each port except the local port W that can additionally raise
iBD/T.The capacity ∑ W that therefore, must transfer extra
iBD/T (for i ≠ this locality).Required capacity can be expressed as C=G+ ∑ W under the weighted-fair
iB+ ∑ W
iBD/T (in last of expression formula, i ≠ this locality).
Can also revise control method to adapt to weighted factor.Can after the value of determining X, revise the method that is used to calculate permission speed as follows:
A
local＝MIN(I
local，W
localX)+W
localB。
Can increase or reduce to come iterative computation X by the recommended value of X being carried out mark, meet following condition up to recommended value:
G ≈ ∑ R
i(for Ri/W
i＜X)+∑ W
iX is (for R
i/ W
i〉=X).
Can following pondage demand to adapt to weighted factor:
C=G+ ∑ W
iB+ ∑ W
iBD/T (last middle i ≠ this locality of expression formula).
Another kind of speed management strategy can be to limit the access rate of single port.For example, can be with the permission speed A of port i
iBe limited in value less than G.When the service provider can not provide visit to port with full committed rate G, or when user's failed call with greater than A
iSpeed when visit, this is useful.
An embodiment of this speed management strategy is to wanting restricted port to use limiting speed value P
LocalIn this case, the A of next period in the ramping method
LocalValue may be calculated:
A
local＝MIN(I
local+B，P
local)
Be limited to P for visit
LocalPort.
For adjusting, the A of next period
LocalValue may be calculated:
A
local＝MIN(P
local，MIN(I
local，X)+B)。
Another kind of interchangeable speed management strategy can be to surpass user's charge of threshold value to the polymerization inlet rate.The method of monitoring aggregation group performance provides at the polymerization inlet rate and has surpassed predeterminated level, for example during threshold value to the chance of higher rate service charging.Can do as one likes can monitor and to be used for detecting and the intersecting of this threshold value.This method does not encourage high level continue to use, but indeterminately forbids this use.In one embodiment, the user can compensate the service provider by the outer rate of amount paid when use surpassing the capacity of committed rate, with evade rising, with promise to undertake to the relevant risk of user's capacity above the service provider.In this case, rate control algorithm is not used for the value of calculative strategy parameter, but is used for calculating when collect extra rate.
In the replaceable speed management strategy of another kind, can with the premium method of aggregation group with combine by the method for specifying two threshold values to carry out rate controlled.An embodiment has been shown among Fig. 2.In first threshold value---the premium threshold value does not have rate controlled below 220.Zone 210 is the base price district.If rate of polymerization is within zone 210, the user pays first price.If the user crosses premium threshold value 220 in second threshold value---G is below 240 for the rate controlled threshold value, and promptly within the zone in Fig. 2 230, the user pays second price for the polymerization inlet rate in the zone 230 so.Second threshold value is more than 240, and promptly the flow in the zone 250 can not cause charged extra, but can not get guaranteeing.Flow in the zone 250 may be dropped or be restricted.
The foregoing description not only has the user can make it be in the advantage that the level below the premium threshold value reduces cost by regulating operating position, but also has the flexibility that allows to use up to the bandwidth of committed rate.For the service provider, present embodiment can be promised to undertake for the resource of deficiency and be protected, and be allowed more high-grade resource use is raised the price.
A kind of speed management strategy can be provided in the method for sharing committed rate between the port of aggregation group.The method of describing in rate control algorithm of distributing rate of polymerization between port is called as " greediness " method of rate adaptation, because it has only reduced the port speed of " greediness " (consuming most of speed), and other ports remain unaffected.Greediness method is described to:
G＝∑Ri(for?Ri＜X)+∑X(for?Ri?≥X)。
A kind of alternative strategy can be, makes each port of aggregation group enjoy the average share or the weighting share of committed rate.This can realize by (or the weighting division) committed rate of simply dividing between port as described below:
A
j=G/n; Or
A
j＝(W
j/∑W
j)G。
Second kind of optional strategy can be, when between port, committed rate being had competition, and can be for consuming the higher permission speed of port assignment of multicapacity.This can divide committed rate pro rata with speed and realize by as described below between port:
A
j＝(R
j/∑R
i)G。
The third optional strategy can be that inlet rate can not regulated its speed less than the port of Mean Speed.The remaining committed rate of other ports share.This strategy can followingly be expressed:
A
j=R
j(R
j≤ G/n); And
A
j=(G-R
iSum)/Q (R
i≤ G/n; R
j＞G/n; Wherein Q is that inlet rate satisfies R
jThe port number of＞G/n.
The method of sharing committed rate comprises above-mentioned option and conceptive similar additive method clearly.
Speed management strategy and rate control algorithm need be distributed the information that relates to speed that is associated with each port member of aggregation group.When describing the method for rate control algorithm and monitoring aggregation group performance, provide a kind of and will be distributed to the method for every other port in the aggregation group from the speed message of each port.Speed message can contain the sign of inlet rate and dispatch ports.Can be decided to be by address with group media access control (MAC, the Media Access Control) address of aggregation group and finish distribution speed message.This method is called as multicast, is well known to a person skilled in the art.(or configuration) group MAC Address relevant with aggregation group can be provided at each port.
The optional embodiment of the method for dispense rate message is the order (or sequence) of specifying the aggregation group middle port.By the single medium accessing to control address of establishing identifies each port through (or configuration) is provided.Then can be by port to next port transmission rate message successively.This method is called as clean culture, is well known to a person skilled in the art.Method to the port ordering is well known to a person skilled in the art.Ordering can circulate, thereby the port at sequence end is to the port transmission rate message of sequence beginning.Can spreading rate message, to allow to carry the measurement inlet rate of each port in the aggregation group, reducing needs the speed message number propagated, and allows the identification aggregation group.When speed message number that hope minimizing and network link intersect, can use sequence method, cost is some extra delay of transmission of rate information.
Second kind of optional embodiment can allow port along the uplink and downlink direction of sequence transmission rate message.That is, along " logic " despining direction transmission rate message.This has reduced the delay of receiving velocity information, and cost is the total corresponding increase that is transmitted speed message.In one embodiment, transmit control message along each direction of logic sequence, it is carrying the speed of only about half of port in the aggregation group.
Other options allow rate information is gathered.In this case, port only the neighbours in its sequence send single rate value.For example, this value can be the weighted average of speed contained in the speed of local measurement and the speed message, and is as follows:
XmitRateMsg.Rate＝(R
i+(n-1)*RcvdRateMsg.Rate)/n。
As described in the optional strategy (wherein giving the equal equal shares or the weighting share of committed rate) of above-mentioned distribution commitment speed for each port, this method and the rate adaptation strategy compatibility that does not need single mensuration inlet rate information.
The method that is used for dispense rate message described in the top embodiment also can be used for other communication informations of distribution between one group of port sharing public speed.
Provide the aforementioned description of the disclosed embodiments, to enable those skilled in the art to finish or use the present invention.Under the prerequisite that does not break away from the spirit or scope of the present invention, those skilled in the art will be easy to expect the various modifications to these embodiment, and the General Principle of this paper definition can be applied to other embodiment.Therefore, the present invention is intended to be limited to illustrated embodiment, but will be interpreted as meeting the wide region of principle disclosed herein and novel feature.
