Description
Technical field
The invention belongs to fields of communication technology, and in particular to a kind of array dispatching method, device, the network equipment and storage are situated between
Matter.
Background technique
In the multi-core network processor framework for having Message processing demand, current mainstream technology scheme are as follows: with ether number
For, after the network interface of processor receives Ethernet message, different messages is sent into different queues according to configuration (can
The message queue to be entered is determined with the message five-tuple HASH value received according to interface, wherein five-tuple HASH value is will to mark
The five-tuple (source IP, destination IP, IP agreement value, source port number, destination slogan) of quasi- Ethernet message is calculated by HASH algorithm
HASH value out), forwarding core again from queue obtain message handled (can configure forwarding core and queue mapping relations,
Some or certain queues are such as assigned to some or certain forwarding cores are handled).
According to above-mentioned network processing unit to the process flow of Ethernet message it is found that processor provides flexible data processing
Mechanism can also not only be handled queue assignment to different forwarding core according to the queue of configuration selection data receiver, but
It is that this configuration cannot be carried out arbitrarily, needs to carry out different configurations according to the difference of application scenarios, by taking router as an example, due to
Router belongs to network intermediary device, realizes the routing forwarding of data, therefore is that cannot change data flow (to have under normal circumstances
The message of identical five-tuple HASH value) sequence, but if the data of same data stream are handled by multiple forwarding cores, just can not
Guarantee the sequence of data flow, therefore for identical data flow, the principle based on order-preserving can only be distributed data flow to same
Queue and by the processing of the same forwarding core, i.e., identical data flow can only enter identical queue, and identical queue can only be by
Identical forwarding core processing.
Under normal circumstances, the number of queue is more much more than forwarding the number of core, therefore certainly exists the more of multiple queues
Data stream is assigned to the case where the processing of the same forwarding core, is more than when handling forwarding nuclear resource consumed by these data flows
It will lead to data flow packet loss when the processing capacity of single forwarding core.

What the network equipment used at present is substantially multi-core processor, and processor architecture is as shown in Figure 1.With ether data
For, after the network interface of processor receives Ethernet message, different messages is sent into different queues according to configuration (can be with
The message five-tuple HASH value received according to interface determines the message queue to be entered), forwarding core obtains message from queue again
Handled (can with dynamic configuration forward core and queue mapping relations, such as by some or certain queues be assigned to some or
The certain forwarding core processing of person).Wherein, five-tuple HASH value is by five-tuple (source IP, destination IP, the IP association of standard Ethernet message
View value, source port number, destination slogan) pass through the calculated HASH value of HASH algorithm.
According to above-mentioned network processing unit to the process flow of Ethernet message it is found that processor provides flexible data processing
Mechanism can also not only be handled queue assignment to different forwarding core according to the queue of configuration selection data receiver, but
It is that this configuration cannot be carried out arbitrarily, needs to carry out different configurations according to the difference of application scenarios.By taking router as an example, due to
Router belongs to intermediary network device, realizes the routing forwarding of data, therefore is that cannot change data flow (to have under normal circumstances
The message of identical five-tuple HASH value) sequence, but if the data of same data stream are handled by multiple forwarding cores, just can not
Guarantee the sequence of data flow, therefore for identical data flow, the principle based on order-preserving can only be distributed data flow to same
Queue and by the same forwarding core processing.
The order-preserving processing for realizing data flow needs to configure according to hardware meter first in multi-core network processor framework
The message five-tuple HASH value calculated carries out the distribution of queue, and identical five-tuple HASH value enters identical queue, in this way
One data stream is only possible to enter a queue, in addition, configuration same queue can only be handled by identical forwarding core, i.e., one
Queue can only be handled by a forwarding core, thus achieved the purpose that a data stream is handled by a forwarding core, realized
The order-preserving of data flow.
Under normal circumstances, the number of queue is more much more than forwarding the number of core, and has identical five-tuple HASH value
Message has very much, therefore a plurality of data flow for certainly existing multiple queues is assigned to the same forwarding core the case where handling, when
It will lead to data flow when handling the processing capacity for forwarding nuclear resource to be more than single forwarding core consumed by these data flows to lose
Packet.
Present inventor has found when studying the above problem: mainstream scheme has problems in that queue and forwarding core
Mapping relations be it is fixed, when distribute to forwarding core all queues in data traffic summation be more than forward core processing
Flow scheduling to other free time can not be forwarded core by way of dynamic dispatching under the premise of data flow order-preserving by ability.Its
In, it should be noted that the reason of for defect present in above scheme and leading to defect is inventor by real
Trample and obtained after carefully studying as a result, therefore, the discovery procedure of the above problem and the hereinafter embodiment of the present invention are for upper
The solution that the problem of stating is proposed all should be the contribution that inventor makes the present invention in process of the present invention.
In consideration of it, as shown in Fig. 2, the embodiment of the present application provides a kind of array dispatching method, applied to having at message
The network equipment for having multi-core processor of reason demand, such as router, firewall.Wherein, multi-core processor includes control core
With multiple forwarding cores.The network equipments configuration has multiple buffer queues, and each forwarding verification in the multiple forwarding core should have
At least one buffer queue, and a buffer queue only corresponds to a forwarding core.It is said below in conjunction with step shown in Fig. 2
It is bright.
Step S101: determine in the multiple buffer queue there are message accumulation the first buffer queue when, the control
Core processed is determined from each forwarding core in the multiple forwarding core in addition to the corresponding first forwarding core of first buffer queue
There is the second forwarding core of processing capacity out.
All buffer queues of nuclear periodicity poll are controlled, have checked whether message accumulation.Determining that it is tired that there are messages
When long-pending first buffer queue, namely show that the corresponding first forwarding core of the first buffer queue is currently at overload state, this
When, control core just determines second turn of processing capacity from each forwarding core in multiple forwarding cores in addition to the first forwarding core
Core is sent out, is handled to reschedule the queue for having message to accumulate to the second forwarding core, forwarding core processing is thus reduced
The risk of ability overload improves system to the response speed of burst flow, realizes the data stream scheduling between forwarding core, keep away
Exempt from unnecessary data flow packet loss problem.
Second turn of processing capacity is being determined from each forwarding cores in multiple forwarding cores in addition to the first forwarding core
When sending out core, it can be according to the consumption value within a preset time of each forwarding core and determine, be also possible to according to each forwarding
The memory accounting of core and/or memory size determine.As an alternative embodiment, below with reference to step shown in Fig. 3
To illustrate that control core determines the detailed process of the second forwarding core.
Step S201: the control core by consumption value of the first forwarding core in preset duration respectively with it is the multiple
Consumption value of each forwarding core in the preset duration in forwarding core in addition to the first forwarding core is subtracted each other, and is obtained more
It is a to subtract each other result.
For example, control core by the first consumption value of the forwarding core in preset duration respectively in N number of forwarding core except first turn
Consumption value of each forwarding core in preset duration outside hair core is subtracted each other, and is obtained N-1 and is subtracted each other result.Assuming that first turn
Sending out consumption value of the core in preset duration is E1, remaining consumption value of each forwarding core in preset duration is respectively E2,
E3... ... En, then the N-1 obtained is a to subtract each other result are as follows: (E1- E2), (E1- E3), (E1- E4) ... ... (E1- EN-1),
(E1- En).Wherein, (E1- E2), (E1- E3), (E1- E4) ... ... (E1- EN-1), (E1- En) these differences have reacted turn
Send out the free processing capacity of core.Wherein, N is the integer more than or equal to 2.
Step S202: the control core chooses maximum subtract each other as a result, as target phase from the multiple subtract each other in result
Subtract result.
For example, the control core chooses maximum phase from a subtract each other of N-1 after obtaining N-1 and subtracting each other result in result
Subtract as a result, subtracting each other result as target.Core is controlled from (E1- E2), (E1- E3), (E1- E4) ... ... (E1- EN-1), (E1?
En) choose maximum difference in this N-1 difference and subtract each other as target as a result, being assumed to be (E1- E2)。
Step S203: it is described greater than what first buffer queue occupied that the control core determines that the target subtracts each other result
The processing consumption value of first forwarding core.
(it is assumed to be (E obtaining target and subtract each other result1- E2)) after, control core judges that the target subtracts each other whether result is greater than
The processing consumption value for the first forwarding core that first buffer queue occupies is determining that target subtracts each other result and account for greater than the first buffer queue
When the processing consumption value of the first forwarding core, step S204 is executed, it is on the contrary then do not handle, wait next polling cycle arrival
The consumption value for recalculating each forwarding core again, is then judged again.Due to (E1- E2), (E1- E3), (E1- E4) ... ...
(E1- EN-1), (E1- En) these differences have reacted the free processing capacity of corresponding forwarding core, when maximum value therein is greater than the
When the processing consumption value for the first forwarding core that one buffer queue occupies, show accordingly to forward core (such as E2Corresponding forwarding core) there is foot
Enough processing capacities remove the message of the first buffer queue of processing.
Step S204: the target is subtracted each other the corresponding forwarding core of result by the control core, as the second forwarding core.
After obtaining target and subtracting each other result, target is subtracted each other into the corresponding forwarding core of result, as the second forwarding core, it is assumed that mesh
It is (E that mark, which subtracts each other result,1- E2), then the second forwarding core is E2Corresponding forwarding core.
Wherein, how control core obtains the consumption value of each forwarding core within a preset time, due to forwarding the consumption of core
Value is closely bound up with the ability for handling data flow, and the ability for handling data flow is both related with the uninterrupted of data flow, also with
The type of data flow is related.(different types of data flow, process flow is different, and the processor resource of consumption is also different).Therefore
Quantitative analysis is carried out firstly the need of to forwarding nuclear resource consumed by different type message, how that obtains processing different type number
The resource of consumption needed for forwarding core according to stream? single can be played respectively for different types of data and cross current-carrying capacity, i.e. data flow
Flow will be more than the processing capacity of single core also only can be by one since a data stream can only enter a queue
Forward core processing, can be obtained by the maximum capacity of single forwarding core processing respective type data in this way, here with IPv4,
IPv6, wide area network POS three types message for, (pass through buffer queue by beating current-carrying capacity to these three messages respectively
Accumulation state judge whether to overload), that is, the single data traffic for corresponding to message need be more than single forwarding core processing capacity,
Single message single-turn hair core processor of three kinds of different type messages available in this way consumes resource, here labeled as Δ tipv4,
Δtipv6, Δ tpos.For example, if individually the processing capacity of forwarding core is 800Kpps, each message needs for IPv4
The resource of consumption forwarding core is 1/800000s, and marking the consumption resource here is Δ tipv4, similarly for IPv6 and wide area network
POS message obtains corresponding single message and individually forwards the relative resource consumption of core to be Δ tipv6With Δ tpos。
Wherein, it should be noted that the relative resource consumption needs of the single message of every kind of message are calculated in advance.This
Sample is when calculating consumption value of each forwarding core in preset duration, it is only necessary to count each forwarding core in preset duration from right
The message data obtained in buffer queue is answered, for example, calculating consumption value E of the forwarding core 1 in preset duration1When, it obtains
The message data for taking forwarding core 1 to obtain from corresponding buffer queue in preset duration, it is assumed that the forwarding corresponding buffer queue of core 1
For queue 1 and queue 2, if IPv4, IPv6, POS message that forwarding core 1 is obtained from queue 1 are calculated as respectively in preset duration
Q1ipv4、Q1ipv6、Q1pos, similarly, IPv4, IPv6, POS message that forwarding core 1 is obtained from queue 2 are calculated as Q2 respectivelyipv4、
Q2ipv6、Q2pos, then forwarding the consumption value of core 1 within a preset time is (Q1ipv4+Q2ipv4) * Δ tipv4+(Q1ipv6+Q2ipv6) *
Δtipv6+(Q1pos+Q2pos) * Δ tpos.Similarly, consumption value E of the forwarding core 2 in preset duration is being calculated2When, obtain forwarding
The message data that core 2 is obtained from corresponding buffer queue in preset duration, it is assumed that the forwarding corresponding buffer queue of core 2 is queue
3 and queue 4, if IPv4, IPv6, POS message that forwarding core 2 is obtained from queue 3 are calculated as Q3 respectively in preset durationipv4、
Q3ipv6、Q3pos, similarly, IPv4, IPv6, POS message that forwarding core 2 is obtained from queue 4 are calculated as Q4 respectivelyipv4、Q4ipv6、
Q4pos, then forwarding the consumption value of core 2 within a preset time is (Q3ipv4+Q4ipv4) * Δ tipv4+(Q3ipv6+Q4ipv6) * Δ tipv6
+(Q3pos+Q4pos) * Δ tpos.And so on, available all forwarding cores processor consumption value E1 within a preset time,
E2…En.Wherein, if message accumulation occurs in queue 1, i.e. queue 1 is the first buffer queue, is turned since queue 1 is assigned to
