The present invention is by first identifying the type of each Business Stream in network transmission, is that flow threshold is set in the transmission of each Business Stream, guarantees the normal traffic transport that each Business Stream can be in Internet Transmission; Simultaneously for each Business Stream transmission of continuous variation adopt the transmission priority delivery flow rate actual with it based on each Business Stream variation to recently determining to occur that large changes in flow rate appears in certain or some Business Streams, be the method for transmitting of dynamically controlling, this method can be guaranteed the normal transmission of Business Stream, can guarantee again the Business Stream transmission of some the large flows in practical application, thereby guarantee the service quality of given traffic streams demand.
As shown in Figure 1, concrete steps are as follows for basic embodiment of the present invention:
The dynamic control method of a kind of Business Stream Network Based that embodiments of the invention provide, comprising:
The mode of the identification here comprises source by gathering the detailed data information of a stream, destination address, port numbers, agreement, type of service, beginning and ending time, bag and byte number etc., and judge by Business Stream, service stream classification and identification, Business Stream sampling, Business Stream monitoring and Business Stream signature analysis and flow modeling technique are identified, wherein for Business Stream and non-Business Stream, mainly by the protocol characteristic word in packet, set out, non-Business Stream wherein mainly refers to proprietary protocol and the common protocol of controlling data stream transmitting, the IGMP of common protocol such as control internet group management etc., and the control protocol of the effect control network nodes data redundancy of proprietary protocol transmission, PRP parallel redundancy agreement for example.
For single business and multi-service, mainly for be that the data that network equipment port receives are further resolved, relate to judgement and the service stream classification of Business Stream here.The wherein general packet row identification that adopts a series of bursts of identical source and destination of the judgement of Business Stream (whether the inter-packet gap time of two be defined as to the standard of same bag), and the method that sets that all packets of same TCP connection are same Business Stream is (according to the sign of Transmission Control Protocol self,, as SYN and FIN carry out Business Stream division).For Business Stream, distinguish generally according to Business Stream attribute, for example: the directivity of transfer of data and end determination methods are as the basis of service stream classification, but need the whole Business Stream feature of further awareness network flow, also must analyze in addition other statistical nature of Business Stream, for example: the size of Business Stream (byte-sized and data package size), rate of rise, Business Stream duration etc.
For example pass through the analysis to network data.Aspect Business Stream size, a lot of real network flow monitoring analyses all find that most Business Stream (approximately 80～90%) is very little, and only have seldom a part of Business Stream (approximately 10～20%) larger, but this part Business Stream has occupied most network traffics (approximately more than 80%), this part occupies network, and to beat the more flow of money be key business stream, for key business stream, is to need prioritised transmission.For key business stream is general, adopt flow value computing method, or business flow rate and Business Stream duration two parameters judge.And the port of the main finger network equipment carries out a plurality of type service stream and transmits for multi-business flow.The traffic flow types here mainly refers to the types of service such as mail or multimedia.
The network equipment is not that independent equipment carries out transfer of data, the network equipment connects into chain or looped network network carries out transfer of data, no matter chain-shaped network or looped network network have the redundancy issue that relates to network equipment transmission data here, integrity problem namely, the reliability here generally all solves by the proprietary protocol of network equipment producer self, such as PRP redundancy protocol (parallel redundancy agreement) and HSR agreement (high reliability redundant looped network) etc.In the chain-shaped network that a plurality of network equipments are connected to form or looped network network, be responsible for the network equipment port of network port logic switch for connecting the main port of other network equipment, general is also the main port of multi-business flow transmission, be referred to as cascade port, that is to say the backbone that is connected to form transmission between cascade port with, but single Business Stream of big data quantity can be also cascade port, cascade port is connected with non-cascade port, but not cascade port by with obtain Business Stream (comprising single Business Stream and/or multi-business flow) being connected of terminal equipment.
103, detect the flow of the Business Stream transmission of non-cascade port within a predetermined period of time, when the actual transmissions flow that this Business Stream detected is lower than it during this Business Stream flow threshold at this non-cascade ports-settings, each Business Stream is according to the setting transmission of transmission priority and degree of seizing; When the actual transmissions flow of this Business Stream being detected and surpass its this Business Stream flow threshold at this non-cascade ports-settings, change the degree of seizing that this Business Stream was originally fixedly installed, and the ratio of the priority of this Business Stream and actual transmissions flow is reset to degree of seizing;
The predetermined amount of time here can make the setting of thinking according to actual conditions, for example: and 30 seconds or 10 minutes, but the time that surpasses flow threshold that this setting-up time should detect than reality is little.Here the method for flow monitoring can be that the flow carrying out based on port numbers according to the port numbers of internet numbering allocation manager mechanism sets; Also can set according to the key characteristics of Business Stream.
Actual transmissions flow during certain Business Stream in non-cascade Port detecting Preset Time, when actual transmissions flow is less than this Business Stream flow threshold, each Business Stream transmits according to the fixedly setting of transmission priority and degree of seizing; And when actual transmissions flow is not less than this this Business Stream flow threshold, should reset degree of seizing according to the ratio of the priority of this Business Stream and actual transmissions flow.
Here to seize kilsyth basalt bright in assigning process, in the situation that residue of network organization bandwidth allows, the actual bandwidth that all Business Streams of the type can obtain accounts for the ratio of the input bandwidth of all Business Streams in type, the value 0 of degree of seizing≤and≤1.
104, according to the variation of the ratio of the Business Stream transmission preferences order of Business Stream actual transmissions flow and non-cascade port, the Business Stream of described former cascade port and non-cascade port is carried out dynamically controlling transmission.
Because existing technical scheme is the priority that arranges of controlling from network data flow value, three dimension directions of degree of seizing and Business Stream minimal maintenance bandwidth have proposed the whole minimum allocation scheme based on each Business Stream, during the transmission of Business Stream, according to predefined priority, the uninterrupted that this Business Stream is used is set, guarantee the minimal maintenance bandwidth of each Business Stream simultaneously, that is to say that Business Stream determines substantially at the flow of transmitting procedure, when whole Business Stream traffic demand is very large, just cannot guarantee the flow of key business stream, in this programme, adopted according to the ratio of the Business Stream transmission preferences order of Business Stream actual transmissions flow and non-cascade port and reset degree of seizing, and the degree of seizing is here a dynamic data, because Business Stream actual transmissions flow is dynamic transmission, also guaranteed the optimal transmission of the high amount of traffic that priority is high.
Based on basic embodiment, further, be illustrated in figure 2 the workflow diagram of multiple services dynamic control method in the Business Stream Network Based that the embodiment of the present invention provides.
When the data type of non-cascade port transmission is multi-business flow, the flow value of each Business Stream receiving in the described multi-business flow in statistics predetermined amount of time, and do ratio computing with the output priority rank of predefined described each respective traffic flows, the highest Business Stream of ratio numerical value is done to override transmission;
And, the flow value that the minimum Business Stream of output priority rank in multi-business flow receives is greater than its predefined threshold value, and when the ratio that output priority rating value predefined with it done ratio computing is minimum, this Business Stream is done to the time-out transmission in Preset Time section.
As shown in Figure 2, concrete steps are:
201: the flow value of each Business Stream receiving in the described multi-business flow in statistics predetermined amount of time, and do ratio computing with the output priority rank of predefined described each respective traffic flows;
202: the highest Business Stream of ratio numerical value is done to override transmission;
203: and, the flow value that the minimum Business Stream of output priority rank in multi-business flow receives is greater than its predefined threshold value, and when the ratio that output priority rating value predefined with it done ratio computing is minimum, this Business Stream is done to the time-out transmission in Preset Time section
In this step, for the multi-business flow transmitting in non-cascade end, for example transmission is video, mail and three kinds of Business Streams of sampling, dividing other transmission priority is 1, 2 and 3, degree of seizing is also respectively 0.4, , 0.4, 0.3, detection through the scheduled time, mail and employing Business Stream value surpass setting threshold, and video is lower than its threshold value, now the actual flow that detects is respectively 2M, 20M, 15M, according to the ratio of the actual transmissions flow of this Business Stream and priority, be respectively 2 so, 10 and 5, now, mail service stream is large Business Stream, namely key business stream, should guarantee prioritised transmission, if now actual detection flow is respectively 2M in addition, 20M, 3M, according to the ratio of the actual transmissions flow of this Business Stream and priority, be respectively 2 so, 10 and 1, now, adopt Business Stream minimum as former transmission priority, and the actual transmissions flow of Business Stream and the ratio of priority are minimum, so this Business Stream is suspended, actual this time is a lot, because normal key business stream is also sudden transmission within the of short duration time period, if Business Stream in practice through occur suspending the situation of transmission, illustrate priority unreasonable of setting.Here need to reset according to actual conditions.
Based on basic embodiment, further, be illustrated in figure 3 the workflow diagram of the dynamic control method of single business in the Business Stream Network Based that the embodiment of the present invention provides.
When the data type of non-cascade port transmission is single Business Stream, this port in statistics predetermined amount of time receives the flow value of business, when the flow value of this port reception business is within a predetermined period of time greater than the flow threshold of this port, using this port as cascade port, according to this list traffic flow types, be connected with other non-cascade port of respective type simultaneously.
As shown in Figure 3, this step is as follows:
301: this port in statistics predetermined amount of time receives the flow value of business;
302: when the flow value of this port reception business is within a predetermined period of time greater than the flow threshold of this port, using this port as cascade port;
303: according to this list traffic flow types, be connected with other non-cascade port of respective type simultaneously.
Because the Business Stream of non-cascade port transmission may be single Business Stream, now, adopt processing mode different and multi-business flow, this programme adopts and will transfer the Business Stream that cascade port continues this type of transmission to, can reduce the difficulty setting of the network port.
Further, be illustrated in figure 4 the workflow diagram that the cascade port of the Business Stream Network Based that the embodiment of the present invention provides is adjusted, the data flow traffic of described former cascade port and non-cascade port is transmitted while controlling and is also comprised: the delivery flow rate to the described network port is adjusted, when the traffic transport threshold value of cascade port is less than the traffic transport threshold value of non-cascade port, adjust the traffic transport threshold value of described cascade port, wherein when the data type of described non-cascade port transmission is multi-business flow, the traffic transport threshold value of described cascade port should be greater than the maximum actual transmissions flow of the Business Stream that ratio numerical value in this cascade port of all processes is the highest.
This step is as follows:
401: the delivery flow rate to the described network port is adjusted;
402: when the traffic transport threshold value of cascade port is less than the traffic transport threshold value of non-cascade port, adjust the traffic transport threshold value of described cascade port;
403: wherein when the data type of described non-cascade port transmission is multi-business flow, the traffic transport threshold value of described cascade port should be greater than the maximum actual transmissions flow of the Business Stream that ratio numerical value in this cascade port of all processes is the highest.
Generally, the traffic transport threshold value of cascade port is larger than non-cascade port flow threshold value, if but for example, because proprietary protocol (redundancy protocol) is according to the redundancy requirement of link, by non-cascade ports-settings, be cascade port, now, the threshold value of non-cascade port is less than the threshold value of cascade port, in real network transmission, be unallowed, for this reason, the Threshold of new cascade port should be greater than the threshold value sum through the highest Business Stream of the ratio of actual transmissions flow and priority
The hardware device of network equipment port can not be unrestrictedly to carry out traffic transport, therefore, need to limit the flow of networking port transmission, guarantees data flow safe transmission.Ordinary circumstance, in network, the Business Stream of large flow is sporadic, flatness that should specified data flow transmission in Internet Transmission, for this reason, the Threshold that should guarantee cascade port should be greater than the threshold value sum through the highest Business Stream of the ratio of actual transmissions flow and priority, that is to say and guarantees that cascade port can transmit the big data quantity that certain Business Stream occurs.Certainly, if simultaneously during other high amount of traffic, need at cascade port, carry out the priority transmission comparison of Business Stream, guarantee that the network port can not paralyse because of data congestion.
