Being the method dynamically controlling transmission, this method both can ensure that the normal transmission of Business Stream, can guarantee that again actual answering
The Business Stream transmission of the big flow of some in, thus ensure that the service quality of given traffic streams demand.
The basic embodiment of the present invention is as it is shown in figure 1, specifically comprise the following steps that
A kind of based on network service flow the dynamic control method that embodiments of the invention provide, including:
Step 101, identify network equipment port transmission data type, described data type include based on
The Business Stream of business transmission and non-traffic stream based on non-traffic transmission, wherein said Business Stream includes according to it
The kind of data type be divided into single Business Stream and multi-business flow；
Here knowledge includes source, destination address, end by the detailed data information of collection one stream otherwise
Slogan, agreement, type of service, beginning and ending time, bag and byte number etc., and by Business Stream judgement, industry
Business flow point class and identification, Business Stream sampling, Business Stream monitoring and Business Stream feature analysis and flowmeter factor skill
Art is identified, and wherein for Business Stream and non-traffic stream, is mainly set by the protocol characteristic word in packet
The most out, non-traffic stream therein is primarily referred to as controlling proprietary protocol and the common protocol of data stream transmitting, public
Such as control the IGMP etc. of internet group management by agreement, and the effect of proprietary protocol controls number of network node
According to the control protocol of redundant transmission, such as PRP parallel redundancy agreement.
For single business and multi-service, it is primarily directed to the data that network equipment port receives and carries out
Further resolve, refer here to judgement and the service stream classification of Business Stream.The wherein judgement one of Business Stream
As use identical source and destination a series of bursts packet row identify (by true for the inter-packet gap time of two
Be set to the standard of the most same bag), and same TCP connect all packets be same industry
Business stream the method that sets (i.e. according to the mark of Transmission Control Protocol self, as SYN and FIN carries out Business Stream
Divide).Business Stream is distinguished and is typically based on Business Stream attribute, such as: the directivity of data transmission and knot
Bundle determination methods, as the basis of service stream classification, however it is necessary that and further appreciates that network traffics entirety Business Stream
Feature, additionally must also analyze other statistical nature of Business Stream, such as: (byte is big for the size of Business Stream
Little and data package size), rate of rise, Business Stream persistent period etc..
Such as by the analysis to network data,.In terms of Business Stream size, a lot of real network flows are supervised
Cls analysis has been found that most Business Stream (about 80～90%) is the least, and the most little a part of Business Stream
(about 10～20%) is relatively big, but this partial service stream occupy most network traffics (about 80% with
On), this part occupies network and beats the more flow of money is key business stream, is needs for key business stream
Prioritised transmission.Typically use flow value to calculate method for key business stream, or business flow rate and Business Stream are held
Continuous two parameters of time judge.And the port referring mainly to the network equipment for multi-business flow carries out many
Individual type service stream is transmitted.Here traffic flow types refers mainly to the type of service such as mail or multimedia.
Step 102, the corresponding flow propagation threshold of related network device port is set according to described data type,
Set each Business Stream transmission priority and degree of seizing, wherein by the port of multi-business flow or in determining the time period
Single service traffics higher than default traffic threshold value time port default be set to cascade port, according to control cascade
Between port, cascade port and non-cascaded port are carried out by the topological relation between proprietary protocol and the network equipment
Connect；
The network equipment is not that single equipment carries out data transmission, and the network equipment connects into chain or looped network network
Carrying out data transmission, no matter chain-shaped network or looped network network relate to network equipment transmission data here
Redundancy issue, namely integrity problem, reliability here the most all passes through network equipment producer self
Proprietary protocol solves, and such as PRP redundancy protocol (parallel redundancy agreement) and HSR agreement are (highly reliable
Property redundant looped network) etc..Multiple network equipments connect in the chain-shaped network or looped network network formed is responsible for network-side
The network equipment port of mouth logic switch is to connect the main port of other network equipment, is typically also multi-service
The main port of streaming, referred to as cascades port, say, that connects between cascade port and forms transmission
Key same, but single Business Stream of big data quantity can also be cascade port, cascade port and non-cascaded port
Connect, and non-cascaded port (includes single Business Stream and/or many by obtaining Business Stream with the connection of terminal unit
Business Stream).
103, the flow of the Business Stream transmission of non-cascaded port within a predetermined period of time is detected, when detecting this
The actual transmissions flow of Business Stream less than its when this Business Stream flow threshold of this non-cascaded ports-settings, respectively
Individual Business Stream is according to the setting transmission of transmission priority and degree of seizing；When the actual transmissions this Business Stream being detected
Flow exceed its when this Business Stream flow threshold of this non-cascaded ports-settings, changed this Business Stream originally solid
The fixed degree of seizing arranged, and the priority of this Business Stream and the ratio of actual transmissions flow are reset and seizes
Degree；
Here predetermined amount of time can make the setting of thinking according to practical situation, such as: 30 seconds or 10 points
Clock, but this setting time should be less than the actually detected time exceeding flow threshold.Here flow
The method of monitoring can be that the port numbers according to Internet number allocation manager mechanism is carried out based on port numbers
Flow sets；Can also set according to the key characteristics of Business Stream.
Actual transmissions flow during certain Business Stream in non-cascaded Port detecting Preset Time, works as actual transmissions
When flow is less than this Business Stream flow threshold, each Business Stream sets according to transmission priority and the fixing of degree of seizing
Surely it is transmitted；And when actual transmissions flow is not less than this this Business Stream flow threshold, it should according to this industry
The priority of business stream and the ratio of actual transmissions flow reset degree of seizing.
Degree of seizing here shows in the assignment procedure, in the case of residue of network organization bandwidth allows, and the type
The actual bandwidth that all Business Streams are obtained in that accounts for the ratio of the input bandwidth of all Business Streams in type, seizes
The value 0≤and≤1. of degree
104, according to the ratio of Business Stream actual transmissions flow with the Business Stream transmission preferences order of non-cascaded port
The change of value, dynamically controls transmission to the Business Stream of described simple port and non-cascaded port.
Owing to existing technical scheme is to arrange priority, degree of seizing and industry from what network data flow value controlled
Three dimension directions of business stream minimal maintenance bandwidth propose overall minimum allocation side based on each Business Stream
Case, arranges, according to priority set in advance, the uninterrupted that this Business Stream uses during the transmission of Business Stream,
Ensure the minimal maintenance bandwidth of each Business Stream, say, that Business Stream is basic at the flow of transmitting procedure simultaneously
On determine that, whole Business Stream traffic demand is the biggest when, just cannot ensure the stream of key business stream
Amount, have employed the Business Stream transmission preferences according to Business Stream actual transmissions flow Yu non-cascaded port in this programme

Stream actual transmissions flow is dynamic transmission, also ensure that the optimal transmission of the high amount of traffic that priority is high.
Based on basic embodiment, further, be illustrated in figure 2 the embodiment of the present invention provide based on network industry
The workflow diagram of multiple services dynamic control method in business stream.
When the data type of non-cascaded port transmission is multi-business flow, statistics predetermined amount of time in described many
The flow value of each Business Stream received in Business Stream, and with each respective traffic flows described set in advance
Output priority rank do ratio computing, Business Stream the highest for ratio numerical value is done override transmission；
Further, the flow value received when the Business Stream that the output priority rank in multi-business flow is minimum is more than
Its threshold value set in advance, and output priority rating value set in advance with it do the ratio of ratio computing
Time minimum, this Business Stream is done the time-out transmission in preset time period.
As in figure 2 it is shown, comprise the concrete steps that:
201: the flow value of each Business Stream received in the described multi-business flow in statistics predetermined amount of time,
And do ratio computing with the output priority rank of each respective traffic flows described set in advance；
202: Business Stream the highest for ratio numerical value is done override transmission；
203: and, when the flow that the Business Stream that the output priority rank in multi-business flow is minimum receives
Value is more than its threshold value set in advance, and output priority rating value set in advance with it does ratio computing
Ratio minimum time, this Business Stream is done in preset time period time-out transmission
In this step, in non-cascaded end transmission multi-business flow, such as transmit be video, mail and
Sampling three kinds of Business Streams, transmission priority respectively is 1,2 and 3, and degree of seizing the most also is 0.4,0.4,
0.3, exceed setting threshold value through the detection of the scheduled time, mail and employing Business Stream value, and video is less than
Its threshold value, the most actually detected flow is respectively 2M, 20M, 15M, then according to the reality of this Business Stream
The ratio of border delivery flow rate and priority is 2,10 and 5 respectively, and now, mail service stream is big Business Stream,
Namely key business stream, it should be ensured that prioritised transmission；If the most actually detected flow is respectively
2M, 20M, 3M, then be 2,10 respectively according to the actual transmissions flow of this Business Stream and the ratio of priority
With 1, now, use Business Stream minimum as former transmission priority, and the actual transmissions flow of Business Stream
Minimum with the ratio of priority, then to be suspended by this Business Stream, this time actual is a lot, because the most the normally off
Key Business Stream is also bursty transmission within the of short duration time period, if Business Stream in practice is through going out
If now suspending the situation of transmission, priority unreasonable set is described.Need exist for according to practical situation
Reset.
Based on basic embodiment, further, be illustrated in figure 3 the embodiment of the present invention provide based on network
The workflow diagram of the dynamic control method of single business in Business Stream.
This port when the data type of non-cascaded port transmission is single Business Stream, in statistics predetermined amount of time
