As shown in Figure 1, Fig. 1 is a kind of this specification process of bandwidth management method shown according to an exemplary embodiment
Figure, comprising the following steps:
Step 101, message is received.
In the present embodiment, it is possible to support the network element of Bandwidth Management, including host, router, interchanger etc., these
The effect of network element includes:
To message bandwidth allocation channel and type, and different processing is provided different types of message；
Flow supervision and traffic shaping, the speed of limitation and input, the output of adjustment message are provided；
Admissions control is provided to determine whether that message uses Internet resources.
Step 102, heading information is read in the message.
Message (message) is the unit exchanged in network with the data cell of transmission and network transmission.Message includes
Complete data information to be sent, length are not required to unanimously.
Message can constantly be packaged into transmission process grouping, packet, frame transmit, and the mode of encapsulation is some controls of addition
The stem of information composition processed, those are exactly heading.
In the present embodiment, if receiving the message of forwarding, bandwidth allocation channel can be read from head (Header)
Required heading information.
Step 103, the message is distributed to the bandwidth channel being adapted to the heading information.
In the present embodiment, bandwidth channel can refer to the virtual channel that message passes through.
A plurality of bandwidth channel is configured in a network, and each bandwidth channel can be used for transmitting different types of flow, by message
Heading information and the setting of bandwidth channel compare, suitable virtual channel is selected, to distributing the message to conjunction
Suitable bandwidth channel.
In one embodiment of the invention, as shown in Fig. 2, step 103 may include steps of:
Step S11 inquires current system time.
Step S12, if the system time was located in the preset entry-into-force time, lookup comes into force within the entry-into-force time
Band-width tactics.
In the present embodiment, multiple band-width tactics can be set previously according to business demand, it can be right by reference bandwidth channel
Message carries out guarantee or speed limit.
The time that the settable entry-into-force time in each band-width tactics, the i.e. band-width tactics come into force.
For example, some band-width tactics is to forbid accessing shopping website, the entry-into-force time of the band-width tactics is workaday 8:
00-18:00, i.e., 8:00-18:00 on weekdays, the band-width tactics come into force, and forbid accessing shopping website.
At this point, current system time can be read, and traverse the entry-into-force time of each band-width tactics, by the system time with
Each entry-into-force time is compared.
If current system time was located in the entry-into-force time, i.e., the band-width tactics come into force, and can be used for and heading information
It is matched.
If current system time was located at outside the entry-into-force time, i.e. the band-width tactics Pending The Entry Into Force is not used to and heading
Information is matched.
Step S13 matches the heading information with band-width tactics.
Step S14, if the heading information and the band-width tactics successful match, the message is distributed to described
The corresponding bandwidth channel of band-width tactics.
In the present embodiment, heading information can be matched with band-width tactics, judges whether the heading information accords with
Close the setting of band-width tactics.
If met, message is distributed to the bandwidth channel indicated to the band-width tactics, flow is limited.
If do not met, message is distributed to the bandwidth channel of not speed limit, is directly sent from network interface.
In one embodiment, two or more band-width tactics are preset, also, each band-width tactics can
Corresponding priority is configured according to business demand.
In this embodiment, the sequence according to priority successively can be carried out heading information and band-width tactics
Matching, until successful match, the high band-width tactics of preferential use priority.
Furthermore, for matching each time, it can be selected from currently not matched band-width tactics and determine highest priority
Band-width tactics.
Judge whether the heading information matches with the band-width tactics of highest priority.
If so, determining the band-width tactics successful match of heading information and highest priority.
If it is not, then return to the band-width tactics that highest priority is selected from currently not matched band-width tactics, i.e., current
With failure, matched next time.
In one example, heading information includes following at least one:
Source domain, purpose domain, source IP address, purpose IP address, source service, source user, source application.
Correspondingly, band-width tactics include following at least one policing parameter:
Reference field, reference address, Reference Services, with reference to user, with reference to application.
Wherein, reference field belongs to security domain, is the set of the networked network of several interfaces, and the user in these networks has phase
Same security attribute.
In band-width tactics, configuration reference field can limit flow, for example, limitation is from Trust (accredited area) to DMZ (non-army
The area Shi Hua) flow.
Reference address belongs to individual address, group of addresses or domain name, and by taking IP address as an example, IP address is one that IP agreement provides
The same address format of kind is a logical address of each network on internet and each host assignment；Domain name is
For identifying the title of a certain computer or calculating unit on network, domain name can be mapped with IP.
In band-width tactics, configuration reference address can limit flow, for example, limitation from 192.168.0.0/24 to
10.10.0.0/24 flow.
Reference Services belong to single service or service group, and so-called service, each level is provided to its upper layer exactly in network
One group of service agreement.Common service type has FTP (File Transfer Protocol, File Transfer Protocol), HTTP
(HyperText Transfer Protocol, hypertext transfer protocol) and DNS (Domain Name System, domain name system
System) etc..
In band-width tactics, configuration Reference Services can limit flow, for example, it is assumed that the service of configuration is HTTP, then it can be with
Limit the flow of HTTP.
It is single user or user group with reference to user, that is, needs to authenticate the user of online.
In band-width tactics, configuration can distribute the size of available bandwidth with reference to user for user, for example, it is assumed that user group,
The available bandwidth of all users in this user group can then be limited.
It is network application with reference to application, that is, needs to carry out the application of network communication.
In band-width tactics, configuration can be to the application limitation speed, for example, it is assumed that configuration mailbox client with reference to application
And download tool, it can be mostly mailbox client distribution necessary bandwidth, reduce bandwidth workable for download tool.
In oneainstance, source domain, purpose domain are compared with reference field, if source domain and purpose domain belong to reference field,
Then determine heading information and band-width tactics successful match.
At this point, message can be distributed to the corresponding bandwidth channel of band-width tactics (reference field), to limit flow.
In another scenario, source address, destination address are compared with reference address, if source address and destination address
Belong to reference address, it is determined that heading information and band-width tactics successful match.
At this point, message can be distributed to the corresponding bandwidth channel of band-width tactics (reference address), to limit flow
System.
In another scenario, source is serviced and is compared with Reference Services, if source service belongs to Reference Services, it is determined that
Heading information and band-width tactics successful match.
At this point, message can be distributed to the corresponding bandwidth channel of band-width tactics (Reference Services), to limit flow
System.
In another scenario, source user is compared with reference to user, if source user belongs to reference to user, it is determined that
Heading information and band-width tactics successful match.
At this point, message can be distributed to bandwidth channel corresponding to the band-width tactics (with reference to user), to limit flow
System.
In another scenario, source is applied and is compared with reference application, if whether source application belongs to reference to application,
Determine heading information and band-width tactics successful match.
At this point, message can be distributed to bandwidth channel corresponding to the band-width tactics (with reference to application), to limit flow
System.
For some business demand, the priority of band-width tactics can be configured that
The priority of band-width tactics belonging to reference field is higher than band-width tactics belonging to reference address；
The priority of band-width tactics belonging to reference address is higher than the band-width tactics with reference to belonging to agreement；
The priority of the band-width tactics with reference to belonging to agreement is higher than the band-width tactics with reference to belonging to user；
The priority of the band-width tactics with reference to belonging to user is higher than with reference to using affiliated band-width tactics.
In the case, as shown in figure 3, heading information and the matched process of band-width tactics are as follows:
In the step s 21, judge whether source domain and purpose domain belong to reference field；If so, S26 is thened follow the steps, if it is not, then
Execute step S22.
In step S22, judge source address and destination address belong to whether reference address；If so, S26 is thened follow the steps,
If it is not, thening follow the steps S23.
In step S23, judge whether source service belongs to Reference Services；If so, S26 is thened follow the steps, if it is not, then executing
Step S24.
Step S24, judges whether source user belongs to reference to user；If so, S26 is thened follow the steps, if it is not, thening follow the steps
S25。
Step S25, judges whether source application belongs to reference to application；If so, S26 is thened follow the steps, if it is not, thening follow the steps
S27。
Step S26 determines heading information and band-width tactics successful match.
Step S27, determining heading information, it fails to match with band-width tactics.
Certainly, above-mentioned band-width tactics and its matching way are intended only as example, in implementing the embodiments of the present invention, Ke Yigen
Other band-width tactics and its matching way are set according to actual conditions, the embodiments of the present invention are not limited thereto.In addition, in addition to upper
State outside band-width tactics and its matching way, those skilled in the art can also according to actual needs using other band-width tactics and its
Matching way, the embodiment of the present invention are also without restriction to this.
Step 104, to the packet labeling type of message for being located at the bandwidth channel.
Message is distributed to the bandwidth channel of adaptation, according to the traffic conditions in bandwidth channel, to the packet labeling
Type of message, thus it is subsequent guaranteed according to the type of message in network interface, the control such as current limliting.
In the concrete realization, on the one hand, the configuration information that bandwidth channel is arranged is read, what bandwidth channel was arranged in acquisition
Independent maximum bandwidth, channel guarantee bandwidth, channel maximum bandwidth.
Wherein, independent maximum bandwidth can refer to maximum bandwidth workable for each source IP address or user.
For example, the independent maximum bandwidth for configuring each source IP address is 1Mbps, all equipment for being matched to the strategy are maximum
Use the bandwidth of 1Mbps.
Channel guarantees that bandwidth can refer to available, minimum upstream and downstream bandwidth in the bandwidth channel, can be used to ensure that key
Business pass through.
For example, configuration Mail guarantee bandwidth is 5Mbps if it is 5Mbps that Intranet mailing system normal use, which needs flow,
The strategy of configuration mailbox client quotes the configuration, in this way, the message of mail can at least use the guarantee flow of 5Mbps, guarantees postal
Part business will not be blocked because of other business bandwidth-hoggings.
Channel maximum bandwidth can refer to workable maximum upstream and downstream bandwidth in bandwidth channel, can be used for limiting certain flows
The bandwidth upper limit used.
For example, configuration maximum bandwidth is 5Mbps, the strategy for configuring download tool quotes the configuration, in this way using downloading work
The maximum speed of tool downloading is 5Mbps.
On the other hand, current message can be calculated to distribute to bandwidth channel, the stream that all messages occupy in bandwidth channel
Total bandwidth is measured, and calculates message and distributes to bandwidth channel, the independent average bandwidth which occupies.
Specifically, the configuration information that bandwidth channel is arranged is read, the channel maximum bandwidth that bandwidth channel is arranged is obtained,
And the quantity of source IP address or user in the bandwidth channel are inquired, by the channel maximum bandwidth divided by the quantity, can be obtained every
The independent average bandwidth that message corresponding to source IP address or user occupies.
At this point, three conditions of setting:
First condition is that independent average bandwidth is more than average bandwidth；
Second condition is that flow total bandwidth is more than to guarantee bandwidth；
Third condition is that flow total bandwidth is more than maximum bandwidth.
By standard (the independent maximum belt of current traffic conditions (flow total bandwidth, independent average bandwidth) and bandwidth channel
Wide, channel guarantees bandwidth, channel maximum bandwidth) it is compared, judge whether to meet above three condition:
In oneainstance, if message does not meet first condition and second condition, the type of message of message is labeled as
Guarantee message.
In another scenario, if message does not meet first condition and third condition and meets second condition, by message
Type of message be labeled as current limliting message.
In addition, if message meets first condition, dropping packets.
Alternatively, if message does not meet first condition and meets second condition and third condition, dropping packets.
In one embodiment, as shown in figure 4, the process compared is as follows:
In step S31, judge whether independent average bandwidth is more than independent maximum bandwidth；If so, thening follow the steps S34；
If it is not, thening follow the steps S32.
In step s 32, judge whether flow total bandwidth is more than that channel guarantees bandwidth；If so, thening follow the steps S33；If
It is no, then follow the steps S35.
In step S33, whether flow total bandwidth is more than channel maximum bandwidth；If so, thening follow the steps S34；If it is not, then
Execute step S36.
Step S34, dropping packets.
Step S35, by the type of message of message labeled as guarantee message.
The type of message of message is labeled as speed limit message by step S36.
Certainly, above-mentioned type of message and its set-up mode are intended only as example, in implementing the embodiments of the present invention, Ke Yigen
Other type of messages and its set-up mode are set according to actual conditions, the embodiments of the present invention are not limited thereto.In addition, in addition to upper
State outside type of message and its set-up mode, those skilled in the art can also according to actual needs using other type of messages and its
Set-up mode, the embodiment of the present invention are also without restriction to this.
Step 105, transmission control is carried out to the message according to the type of message.
In the present embodiment, guaranteed at the speed limit of network interface with markd message, the processing such as current limliting.
In the concrete realization, the configuration file that network interface is arranged is read, the maximum belt that network interface is arranged is obtained
Wide and reserved bandwidth.
Wherein, maximum bandwidth, refers to the bandwidth upper limit in network interface in/out direction, and configurable bandwidth range is
8Kbps-10Gbp, all flows of maximum bandwidth all can be used, can be used for limiting network interface allow by maximum bandwidth.
Reserved bandwidth, refers to the reserved bandwidth in network interface in/out direction, and reserved bandwidth only allows certain form of stream
Amount (as guaranteed message) passes through, and guarantees that the message of key business will not be dropped.
At this point, the standard (maximum bandwidth and reserved bandwidth) of current traffic conditions and network interface can be compared:
In oneainstance, if message is empty with first in addition to reserved bandwidth in speed limit message and maximum bandwidth
Not busy bandwidth then occupies the first idle bandwidth, sends message.
In another scenario, if message is the not had in addition to reserved bandwidth in speed limit message and maximum bandwidth
One idle bandwidth, then dropping packets.
In another scenario, if message is to guarantee there is the second idle bandwidth in message and reserved bandwidth, the is occupied
Two idle bandwidths send message.
In another scenario, if message is to guarantee do not have the second idle bandwidth, maximum belt in message and reserved bandwidth
There is the first idle bandwidth in addition to reserved bandwidth in wide, then occupy the first idle bandwidth, send message.
In another scenario, if message is to guarantee do not have the second idle bandwidth, maximum belt in message and reserved bandwidth
Do not have the first idle bandwidth in addition to reserved bandwidth in wide, then dropping packets.
Wherein, the first idle bandwidth and the second idle bandwidth belong to idle bandwidth, i.e., unappropriated bandwidth.
For reserved bandwidth, if the message abandoned at network interface includes to guarantee message, can dynamically raise reserved
Bandwidth makes it preferentially pass through guarantee message, will not seize excessive bandwidth by the speed limit message of a large amount of nonessential business.
In one embodiment, configuration file is read, is obtained in advance to the maximum bandwidth of bandwidth channel setting.
The ratio fixed to maximum bandwidth fetching, tone pitch in acquisition carry out on the basis of reserved bandwidth according to upper tone pitch
It adjusts, until raising to upper limit value.
For example, upper tone pitch can be calculated by following formula:
32Kbps* interface configures (Kbps)/(10*1024Kbps)
If configuring 10Mbps, the reserved bandwidth of network interface can be increased into 32Kbps, herein, highest up-regulation is online
For 256Kbps.
Hereafter, if the message abandoned, which does not include, guarantees message, reserved bandwidth can be dynamically adjusted back, until falling after rise to first
The value of beginning.
In one embodiment, record bandwidth channel in a upper period (one second as above), guarantee message first
Quantity.
Using the first quantity as reference, estimate in subsequent time period (such as next second), the second quantity of guarantee message.
For example, it is assumed that the quantity of message keeps balance in the short time, it may be considered that in a upper period, guaranteeing message
First quantity is equal in subsequent time period, guarantee the second quantity of message.
Lower tone pitch is calculated according to the second quantity, and on the basis of reserved bandwidth, is lowered according to lower tone pitch, until returning
Drop down onto original value.
In this specification embodiment, receive message, in messages read heading information, by message distribute to heading
The bandwidth channel of information adaptation passes the packet labeling type of message for being located at bandwidth channel according to type of message to message
Defeated control carries out corresponding Bandwidth Management, it can be achieved that various configurations scheme, more reasonably divides based on bandwidth channel, type of message
With bandwidth, bandwidth exhaustion is avoided, simplifies configuration flow, network administrator's reasonable distribution bandwidth resources is effectively helped, to be promoted
Network operation quality.
