Specific embodiment
To keep the purposes, technical schemes and advantages of disclosure embodiment clearer, below in conjunction with attached drawing to this public affairs
The technical solution opened is clearly and completely described, it is clear that and described embodiment is a part of embodiment of the disclosure,
Rather than whole embodiment.Based on the embodiment in the disclosure, those of ordinary skill in the art are not making creation
Property labour under the premise of every other embodiment obtained, belong to the disclosure protection range.
In order to make it easy to understand, the flow control methods that disclosure embodiment provides are said by taking SmartMC networking as an example
Bright, certainly, which can also be applied in other networkings.
Firstly, the disclosure briefly introduces the network structure of SmartMC networking.As shown in Figure 1, the SmartMC group
Net includes management equipment, member device and ftp server；Every member device and ftp server are connect with management equipment respectively；
The network structure of SmartMC networking in Fig. 1 is merely illustrative, and is not specifically limited, and the network structure of the SmartMC networking is also
It can be other network structures, as member device can also connect other member devices.Above-mentioned management equipment is referred to as
Topology master, above-mentioned member device are referred to as Topology client.
In general, usually only having a management equipment in a SmartMC networking, other equipment are member device.Network
Equipment (management equipment and member device belong to the network equipment) itself is usually each equipped with SmartMC function, by this
SmartMC function is configured, and wherein can will be appointed as management equipment by a network equipment, other network equipments set for member
It is standby.In addition, management equipment can be realized and criticized to all member devices in networking by being configured in management equipment
Buret reason, for example, carrying out backup and download configuration file to member device, software release upgrade, issuing configuration and failure in batches
Equipment replacement etc..
In SmartMC networking, management equipment and member device pass through SmartMC broadcasting packet and response message perception pair
The presence of side；Management equipment regularly sends SmartMC broadcasting packet (sending within such as every 15 seconds primary), and member device receives management and sets
When standby SmartMC broadcasting packet, it will check that the management equipment MAC Address carried in SmartMC broadcasting packet is set with member
Whether the management equipment MAC Address of note is consistent；If consistent, response message is responded to management equipment if member device；Such as
Fruit member device is received in the certain time interval after SmartMC broadcasting packet (such as two minutes) and is not received again by
SmartMC broadcasting packet, then it is assumed that management equipment is not present, and member device will remove the information of the management equipment.Management equipment
When receiving the response message of member device, it will check the member device MAC Address and local record carried in response message
Whether the member device MAC Address is consistent；If consistent, illustrate that the member device exists.If management equipment receives this
(such as 150 seconds) are not received again by the response report of the member device in certain time interval after the response message of member device
Text, then it is assumed that the member device is offline, and member device is set to off-line state by management equipment.
Based on the mutual perception mode of management equipment and member device in above-mentioned SmartMC networking, if a large amount of flows gush
Enter above-mentioned SmartMC networking, the response message that the SmartMC broadcasting packet or member device that management equipment is sent return may
Because port congestion or transmitted to CPU queue have been expired and have been dropped；Management equipment is easily led to accidentally to set the member device of presence
For off-line state, thus the operation of SmartMC function can not be carried out to the member device again, to influence SmartMC networking
Stability.
Based on this, the disclosure provides a kind of flow control methods, and this method is applied to the management equipment in networking in equipment；
Equipment further includes the member device connecting with management equipment in the networking；As shown in Fig. 2, this method comprises the following steps:
Step S202, the rate utilization rate for obtaining first interface in networking reach the first equipment of scheduled rate threshold value, the
One interface are as follows: the interface being connect with equipment in networking；
Wherein, which can be member device, or management equipment；Above-mentioned first interface can specifically be managed
Solution is interface interconnected between equipment in networking, for example, for management equipment itself, the first interface of management equipment be with
The interface that member device connects in networking；For a certain member device, the first interface of member device is to set with management in networking
The interface of standby or other member devices connection.In addition to above-mentioned first interface, management equipment and member device may in networking
In the presence of the interface for connecting networking external equipment.The rate utilization rate of interface can be understood as the currently used rate of interface
With the ratio of the preset total rate of the interface；The rate utilization rate of interface can be divided into the rate utilization rate into direction and go out side
To rate utilization rate, total rate of the total rate and direction out that enter direction is usually identical.
Based on above-mentioned, direction can be preset out and enter the threshold value of the rate utilization rate in direction, by the threshold value with it is each
The rate utilization rate of the first interface of equipment is compared in networking, so that it is determined that setting in equipment with the presence or absence of first in networking
It is standby, and then obtain first equipment.Since management equipment or member device may have the interface of connection networking external equipment, pipe
Reason equipment or member device be likely to pour in a large amount of flows, therefore, which may be management equipment, it is also possible to be at
Member's equipment.
Step S204 is determined in the first equipment with the presence or absence of the second interface for flowing into flow, second interface are as follows: outside networking
The interface of equipment connection；
If a large amount of flows pour in networking in a short time, it will usually it is poured in by one or more equipment in networking,
The equipment for pouring in a large amount of flows is above-mentioned first equipment to be determined；The second interface that a large amount of flows usually pass through equipment is gushed
Enter, and is exported by first interface to equipment in other networkings；Therefore, in the first interface of the first equipment, usually have one or
Multiple first interfaces go out direction rate utilization rate with higher, but enter direction speed with higher there is no first interface
Rate utilization rate.For other networking equipments in addition to the first equipment, go out direction tool if there is one or more first interfaces
There is higher rate utilization rate, usually centainly there are one or more first interfaces enters direction rate utilization rate with higher.
Step S206 judges the purpose for the message that the second interface from the first equipment receives if there is second interface
Address, if match with the interface message of the first interface of equipment in networking；
Step S208 carries out flow control according to second interface of the judging result to the first equipment.
In actual implementation, the message that the second interface in designated time period receives can be acquired, such as the first equipment
The rate utilization rate of first interface is higher than period when certain threshold value, that is, acquires the second interface of the first equipment in the period
The message received.Alternatively, it is also possible to intermittently acquire, for example, within the above-mentioned period, at interval of some cycles acquisition one
Segment message.The acquisition geometry of specific message is it is not limited here.
When carrying out flow control, such as certain second interfaces of the first equipment can be closed, thoroughly prevent flow from this
Second interface enters, and the rate of interface can also be limited by QoS (Quality of Service, service quality), to drop
The speed that low discharge enters；Which kind of control mode is specifically used, the destination address for the message that can be acquired according to first equipment
Determine, for example, the destination address can for the purpose of IP address, target MAC (Media Access Control) address etc..
The above-mentioned flow control methods that disclosure embodiment provides, the rate of first interface utilizes in acquisition networking first
Rate reaches the first equipment of scheduled rate threshold value；And then it determines in first equipment with the presence or absence of the second interface for flowing into flow；
If it is present judging the destination address for the message that the second interface from the first equipment receives, if with equipment in networking
The interface message of first interface matches, and finally carries out flow control according to second interface of the judging result to the first equipment.It should
In mode, if a large amount of flows are poured in by some equipment in networking, management equipment is mutually interconnected according between equipment in networking
The equipment is determined as the first equipment, and the purpose of the message received based on the first equipment by the rate utilization rate of the interface connect
Address carries out flow control to the first equipment and avoids flow congestion from causing management equipment so that the flow in networking is relatively stable
Communication message is dropped between member device, is conducive to management equipment to the operational administrative of member device, to improve group
The stability of net.
Disclosure embodiment also provides another flow control methods, and embodiment emphasis description obtains in networking the
The rate utilization rate of one interface reaches the first equipment of scheduled rate threshold value, and determines to exist in first equipment and flow into flow
Second interface detailed process, as shown in figure 3, this method comprises the following steps:
Step S302, according to predetermined period, into networking, member device sends acquisition instruction, and the acquisition instruction is for obtaining
The rate utilization rate of first interface.
Predetermined period therein can be preset, such as 15 seconds.For different networkings, above-mentioned acquisition instruction can have
Different formats, the acquisition instruction can be preset, and can also be realized by relevant network configuration protocol, for example, Netconf is assisted
View；Specifically above-mentioned acquisition instruction can be formed by the relevant entries in Netconf agreement, to obtain the first interface of member device
Actual flow rate and total rate, so that rate utilization rate be calculated.
Step S304 receives the rate utilization rate for the first interface that member device returns；The rate utilization rate includes first
Interface goes out the rate utilization rate in direction and enters the rate utilization rate in direction.
Step S306, according to the rate utilization rate of the first interface of above-mentioned predetermined period acquisition management equipment itself.
It should be noted that management equipment itself is also likely to be present first interface, management equipment directly acquires itself
The rate utilization rate of one interface.Certainly, the rate utilization rate of the first interface of management equipment also includes that first interface goes out side
To rate utilization rate and enter the rate utilization rate in direction.
For same interface, which can be used for receiving flow, i.e. the direction of flow is into direction, which can also be with
For transmitted traffic, the direction of the flow is direction；The total rate for going out direction and entering direction of one interface is usually identical, but
Direction and the actual flow rate for entering direction are typically different out, thus need to obtain the rate that above-mentioned first interface goes out direction respectively
Utilization rate and the rate utilization rate for entering direction；I.e. go out direction rate utilization rate=go out direction actual flow rate/total rate；
Enter actual flow rate/total rate in the rate utilization rate in direction=enter direction.
Step S308 judges in networking in the first interface of equipment, if the rate utilization rate that there is direction out is greater than the
The first interface of one rate-valve value；If it does, executing step S310；If it does not, terminating.
The rate utilization rate in direction out is greater than equipment belonging to the first interface of first rate threshold value and determined by step S310
For the first equipment.
Step S312 judges to whether there is in the first equipment the rate utilization rate into direction is greater than the second rate-valve value the
One interface；If it does not, executing step S314；If it does, terminating.
Step S314 determines the second interface for existing in the first equipment and flowing into flow.
Above-mentioned first rate threshold value and the second rate-valve value can be preset, first rate threshold value and the second rate-valve value
It may be the same or different, it, can also be with first rate threshold if first rate threshold value and the second rate-valve value are disposed as 75%
Value is set as 75%, and the second rate-valve value is disposed as 70% etc..If there is the speed in direction in the equipment A in networking in equipment
Rate utilization rate is greater than the first interface of first rate threshold value, then equipment A can be identified as the first equipment；Assuming that the of equipment A
One interface be interface 1 and interface 2, but equipment A be not present into direction rate utilization rate be greater than the second rate-valve value first
Interface illustrates that above-mentioned interface 1 and interface 2 is caused to go out the higher flow of rate utilization rate in direction, it may be that from non-first interface
It flows into, i.e., the interface connecting from equipment A with networking external equipment flows into, that is, can determine that equipment A has flow into flow second
Interface.
Contrastingly, if equipment B is not the source equipment of a large amount of flows, it will usually which the rate that both there is direction utilizes
Rate is greater than the first interface of first rate threshold value, and the rate utilization rate that there is direction is greater than the first of the second rate-valve value and connects
Mouthful, for example, the first interface that the rate utilization rate for going out direction of equipment B is greater than first rate threshold value is interface 1, enter the speed in direction
The first interface that rate utilization rate is greater than the second rate-valve value is interface 2, then illustrates that flow is flowed into from interface 1, flow out from interface 2,
Even if equipment B, there are second interface, the rate utilization rate in the rate utilization rate for entering direction of the second interface and out direction is equal
Not up to corresponding rate-valve value, illustrating the equipment not is the first equipment of a large amount of flows.
Step S316 judges the destination address for the message that the second interface from the first equipment receives, if in networking
The interface message of the first interface of equipment matches；
Step S318 carries out flow control according to second interface of the judging result to the first equipment.
In aforesaid way, management equipment obtains the rate utilization rate of the first interface of equipment in networking according to predetermined period,
And then judge to whether there is the first equipment in networking in equipment, and judge that first equipment connects with the presence or absence of flow into flow second
Mouthful；If it is present judging the destination address for the message that the second interface from the first equipment receives, if with equipment in networking
The interface message of first interface match, flow control is carried out according to second interface of the judging result to the first equipment.Pass through
Aforesaid way can quickly be judged to pour in a large amount of flows pour in equipment in networking the first equipment and first equipment
The second interface of flow, and flow control is carried out to the second interface, to improve the stability of networking.
Disclosure embodiment also provides another flow control methods, which describes to the first equipment
Second interface carries out the detailed process of flow control, as shown in figure 4, this method comprises the following steps:
Step S402 obtains the interface mac address of the first interface of equipment and the first interface of management equipment in networking
The target MAC (Media Access Control) address of the specified message received；The specified message is the message that purpose address is multicast address；
Step S404, the interface mac address and target MAC (Media Access Control) address that will acquire are saved as address to be matched to service
Device；
The purpose of above-mentioned steps is to acquire a part of MAC Address in advance, and save as MAC Address set to be matched,
If the destination address of message belongs to the MAC Address set, effective discharge can be determined as.Due to two layers of part association in networking
It discusses corresponding message and passes through multicast form and communicated, it is thus regarded that the corresponding message of already present multicast address is in networking
Effectively, such as LLDP (Link Layer Discovery Protocol, Link Layer Discovery Protocol) agreement, STP (Spanning
Tree Protocol, Spanning-Tree Protocol) agreement etc. message.
Step S406, according to predetermined period, into networking, member device sends acquisition instruction, and the acquisition instruction is for obtaining
The rate utilization rate of first interface.
Step S408 receives the rate utilization rate for the first interface that member device returns；The rate utilization rate includes first
Interface goes out the rate utilization rate in direction and enters the rate utilization rate in direction.
Step S410, according to the rate utilization rate of the first interface of above-mentioned predetermined period acquisition management equipment itself.
Step S412 judges to whether there is the management equipment or member device for meeting preset condition in networking in equipment；It should
Preset condition are as follows: the rate utilization rate that there is direction out is greater than the first interface of first rate threshold value, and is not present into direction
Rate utilization rate is greater than the first interface of the second rate-valve value；If it does, executing step S414；If it does not, terminating.
Step S414 determines that there are the first equipment in equipment in networking, from all second interfaces of the first equipment, screening
The rate utilization rate for entering and leaving direction is greater than the second interface of third speed threshold value；
The third speed threshold value can be preset, such as 30%.In general, entering the rate utilization rate higher second in direction
Interface is likely to be the interface for pouring in a large amount of flows, is based on this, and the rate utilization rate lower second without obtaining into direction connects
The message that mouth flows into generally also is not necessarily to control the flow of the lower second interface of rate utilization rate into direction, thus the step
The more interface of incoming traffic is filtered out, to reduce operand, improves the efficiency of flow control.
Step S416 is obtained at the appointed time section, the message flowed into from the second interface filtered out.
The designated time period can be the period for pouring in a large amount of flows, can specifically be determined by following manner: when true
Make in networking in equipment there are when the first equipment, by determine in networking in equipment there are on the basis of at the time of the first equipment it
Designated time period afterwards, such as 1 minute；The message flowed into from the second interface filtered out is acquired in the designated time period.?
In actual implementation, in the designated time period, the message flowed into from the second interface that filters out can be constantly acquired, it can also be with
Intermittently it is acquired.For example, designated time period was 1 minute, at interval of continuous collecting 5 seconds 10 seconds.
Step S418 is filtered processing to collected message according to the forwarding priority of message；
Since the purpose of flow control methods in present embodiment is in order to avoid a large amount of flow congestion interfaces cause to manage
Communication message between equipment and member device is lost, and because different messages have different forwarding priorities, in same interface
Under, the higher message prior forwarding of forwarding priority, the lower message of forwarding priority may come forwarding position rearward,
Even when interface exceeds total flow, the lower message of forwarding priority may be dropped.Based on this, for forwarding priority
Lower than the message of the communication message between management equipment and member device, usually will not influence logical between management equipment and member device
The forwarding for believing message, because without controlling these messages.It, specifically can be by forwarding priority lower than pipe in above-mentioned steps
The message of communication message between reason equipment and member device is filtered processing, which can be further reduced operand, subtract
Few cpu busy percentage, improves the efficiency of flow control.
Step S420, for each second interface filtered out, the target MAC (Media Access Control) address for the message that current second interface flows into
It is sent to server, so that server matches the target MAC (Media Access Control) address of message with the interface message of first interface；
Step S422 judges the whether whole successful match of the target MAC (Media Access Control) address for the message that current second interface flows into；If
It is to execute step S424；If it is not, executing step S426；
Step S424 determines the destination address that current second interface flows into, the interface with the first interface of equipment in networking
Information matches；Reduce the rate of current second interface；Terminate.
Step S426 closes current second interface.
In actual implementation, message can be classified according to the interface of message flow, is directed to each filters out one by one
Second interface flow into message handled.Above-mentioned steps S402 and S404 have obtained MAC Address set to be matched,
Thus in the step, for each interface filtered out, by the target MAC (Media Access Control) address of the message of the interface flow, one by one with it is above-mentioned
MAC Address set to be matched is matched, if the target MAC (Media Access Control) address of message is with having been saved in above-mentioned MAC to be matched
In the set of location, then message matching success, the message is effective discharge.
In most instances, the message that each interface flows into is multiple messages, therefore, in a kind of mode, when all reports
When Wen Jun is effective discharge, then can determine interface inflow is effective discharge；As long as one of message is not effectively to flow
Amount, it is determined that interface flowed into is invalid traffic.In another message, when the percentage of the message of effective discharge reaches centainly
When threshold value, can determine interface inflow is effective discharge, when the percentage of the message of effective discharge is lower than the threshold value, then
Determine interface inflow is invalid traffic.
If the target MAC (Media Access Control) address successful match of whole messages of current interface, server can be returned to management equipment
Verification value, after management equipment receives the verification value, the filtered message for determining that current interface flows into is effective discharge.If worked as
The target MAC (Media Access Control) address of the message of front port is without whole successful match, then server can return to negative value, management to management equipment
After equipment receives the negative value, the filtered message for determining that current interface flows into is invalid traffic.
When the interface flow into be invalid traffic when, illustrate that these flows may be infected information, broadcast storm etc., be not necessarily to
These flows are forwarded again, at this point, then can directly close the interface, after closing a period of time, can reopen the interface.When
When what the interface flowed into is effective discharge, it if direct down interface, may cause the interruption of communication service, can then drop at this time
The rate of the low interface can specifically reduce total rate of current interface, such as reduce by 10%, 50%.After reducing a period of time,
It can also restore total rate of the interface.
In aforesaid way, when determining in networking that there are rate benefits after the first equipment, screened first into direction in equipment
It is greater than the second interface of third speed threshold value with rate, further according to the forwarding priority of message, filters and flowed into from the interface filtered out
Message improve the efficiency of flow control to reduce operand；And then again for the second interface each filtered out, judgement should
The target MAC (Media Access Control) address for the message that second interface receives matches with the interface message of the first interface of equipment in networking；If
Matching then reduces the rate of current interface, closes current interface if mismatching, it is ensured that while networking normal communication,
Invalid traffic is avoided to influence the communication message of management equipment and member device, to improve the stability of networking.
Disclosure embodiment also provides another flow control methods, the embodiment by taking SmartMC networking as an example into
Row explanation, Fig. 5 show a kind of example of SmartMC networking, wherein equipment A is management equipment, equipment B, equipment C, equipment D,
Equipment E is member device, and equipment F is the equipment other than SmartMC networking, such as Fig. 5 of connection relationship each other.Equipment A

Location.
The process for establishing SmartMC network automatically is described first below:
It step 01, can be specified by the SmartMC function after management equipment and member device open SmartMC function
Management equipment, such as above equipment A.Management equipment sent a SmartMC broadcasting packet every 15 seconds (being only used as example), this is wide
The information such as IP address of the MAC Address of Portable device A, virtual local area network interface Vlan-interface1, inquire net in casting text
It whether there is member device in network.
Step 02, after member device receives broadcasting packet, the facility information of record management equipment, such as the MAC of above equipment A
Address, IP address of virtual local area network interface Vlan-interface1 etc.；Member device is mono- to management equipment transmission SmartMC
Response message is broadcast, MAC Address, the virtual local area network interface Vlan- of member device itself are encapsulated in the response message
The information such as the IP address of interface1.
Step 03, after management equipment receives the response message of member device, the default user name of member device and close is used
Code establishes Netconf session with member device such as user name admin, password admin, and passes through the acquisition conversation member device
Details, such as port information, LLDP neighbor information, STP information, device type, the software version of member device etc..
Step 04, management equipment is established keep-alive with member device and is connect, and member device is added to SmartMC network.
