Embodiment
Hereinafter will and combine embodiment to specify the present invention with reference to accompanying drawing.Need to prove that under the situation of not conflicting, embodiment and the characteristic among the embodiment among the application can make up each other.
Present embodiment describes with the example that is implemented as tactful on the single port among the HQoS based on the HQoS technology.
Fig. 2 is that as shown in Figure 2, this method can may further comprise the steps (step S202-step S206) according to the flow chart of the manner of execution of the HQoS strategy of the embodiment of the invention:
Step S202, whether the timesharing strategy that detects the designated port binding according to the current time is in section effective time, if, execution in step S204, otherwise execution in step S206;
Step S204 carries out the timesharing strategy at above-mentioned designated port;
Step S206 carries out the default policy that this designated port is bound at above-mentioned designated port.
Present embodiment passes through said method; At this timesharing strategy of the section execution effective time of timesharing strategy; Carry out the default policy that is bound to this port in the other times section, make above-mentioned port to carry out different strategies in the different time section, the single direction that has solved at same physical port only allows to dispose the feasible inconvenient problem of strategy of revising of a strategy; And the mode of this execution dynamic strategy can be more suitable for the situation of change of network, makes the HQoS The Application of Technology convenient with maintenance.
In order to satisfy HQoS, can before the step S202 of said method,, and section effective time of timesharing strategy be set for above-mentioned designated port is bound at least one timesharing strategy in the demands of different of different time sections for the service quality of single port; Timesharing strategy after being provided with is recorded in the database.For example, for a certain timesharing strategy, the port numbers that can bind according to the timesharing strategy and direction, strategy numbering, effective time, the order of section, tactful content was inserted in the database table.By this method, can more than one timesharing strategy be set, thereby can guarantee, can also practice thrift network operation maintenance cost more for the user provides the service quality that more becomes more meticulous for a direction of a port.
When using the manner of execution of above-mentioned strategy; Exist two or more Different Strategies to be in the term of validity in the identical moment; Thereby the problem that clashes, can also the effective time that the timesharing strategy is set judge during section Set For Current the timesharing strategy effective time section with above-mentioned database in section effective time of the timesharing strategy that writes down whether conflict; If section effective time of the timesharing strategy of Set For Current is revised in prompting; Certainly, if there is not conflict, then direct timesharing strategy with Set For Current is recorded in this database.
For example; In effective time that the timesharing strategy is set during section; If section effective time of the timesharing strategy that writes down in the time period of discovery Set For Current and the database has lap; The beginning or end of perhaps finding the time period of Set For Current is included in the effective time of the timesharing strategy that writes down in the database in the section, and then section effective time of the timesharing strategy of Set For Current is revised in prompting.The implementation method of this prompting has a variety of, for example, can be shown to the personnel of setting through the dialog box form, also can personnel be set with the prompting of alarm prompt sound and reset section effective time.
Through said method, can, the timesharing strategy avoid existing two or more Different Strategies to be in the problem that clashes when the term of validity makes above-mentioned port in strategy execution when being set in the identical moment, make that present technique reliability when practical application is stronger.
When above-mentioned designated port is provided with more than one timesharing strategy; Do not clash in order to ensure the time of implementation of default policy and section effective time of above-mentioned more than one timesharing strategy; Promptly there is not common section effective time of Different Strategies; Can detect corresponding section effective time of each timesharing strategy of designated port in the database according to the current time; If the current time is not in each timesharing strategy corresponding effective time in the section, the result who then confirms to detect is not for, thereby carries out the default policy that this designated port is bound.Through this method, the situation of having avoided the time of implementation section of default policy and more than one timesharing strategy on the same port to clash has improved the reliability of present technique.And this mode also can be through carrying out the service quality that default policy ensures network side.
Consider that HQoS carries out unified management for multi-user, multiple business, multiple flow, the demand of graded dispatching can also be bound at least one multistage timesharing strategy for designated port.Fig. 3 is the policy configurations sketch map according to the tree structure HQoS traffic classification of the embodiment of the invention.In the present embodiment, HQoS is applied in the network of number of different types: common IP network, QINQ (also claiming Stack VLAN or Double VLAN) network and VPN (Virtual Private Network is called for short VPN).Altogether level Four scheduling of HQoS, according to the difference of network type, traffic classification is according to difference, for example: Level1 is a service priority, possibly mate CoS or the IP_PRECEDENCE in the IP heading among the vlan; Level2 is matching access control list (Access Control List is called for short ACL) or user vlan (cvlan) or virtual channel identification (Visual Channel ID is called for short VC_ID); Level3 coupling vlan information (when multilayer vlan is the outer vlan of operator, i.e. svlan) or Tunnel Identifier (TUNNEL_ID); The designated port of strategy is put in the Level4 assignment.
As shown in Figure 3, in effective time that the timesharing strategy is set during section, section effective time of every grade of timesharing strategy in the multistage timesharing strategy can be set step by step; Wherein, the effective time that section effective time of next stage timesharing strategy is contained in upper level timesharing strategy in each multistage timesharing strategy is in the section, and section effective time of same other each timesharing strategy of level is not overlapping.
For example, for the substrategy of the Level2 among Fig. 3, Level3 is exactly the timesharing strategy of its upper level, and the substrategy of Level1 is exactly the timesharing strategy of its next stage.Can dispose all kinds of QoS service strategies for Level1 to Level3; For example: traffic shaping, Weighted Fair Queuing (Weighted Fair Queuing is called for short WFQ) scheduling; Strict priority scheduling; Priority modification, Weighted random detect (Weighted Random Early Detection, be called for short WRED) etc. in advance.Wherein the strategy of Level1 depends on the Level2 strategy as 1 straton strategy; The Level2 strategy depends on certain Level3 strategy, have only the Level3 strategy can with the port binding that is positioned at Level4, port is the root of strategy.
Through the above-mentioned method that multistage timesharing strategy is set, can further improve the degree that becomes more meticulous of the service quality of HQoS, improved user experience, also can further practice thrift network operation maintenance cost simultaneously.For example; In the timesharing strategy 1 of Level3, being provided with provides the flow of business datum bigger working day; The flow of audio frequency, video is less, and be set 9 of morning in the timesharing strategy 1 of Level2, and extremely evening, 6 business datum flows were bigger, and the flow of audio frequency, video is less; The business datum flow that be set 2 pm to 5 of evenings in the timesharing strategy 11 of Level1 is bigger, and the flow of audio frequency, video is less.Through this set, can limited utilization rate of network resource be maximized as much as possible.
When above-mentioned designated port is provided with multistage timesharing strategy; Section effective time in order to ensure different timesharing strategies is different; Can be when multistage timesharing strategy be provided with step by step; Adopt following manner: if Duan Wei effective time of the timesharing strategy of Set For Current is contained in the effective time of its upper level timesharing strategy in the section, section effective time of the timesharing strategy of Set For Current is revised in prompting; Perhaps, if section effective time of other timesharing strategy in the same rank of Duan Yuqi effective time of the timesharing strategy of Set For Current is overlapping, section effective time of the timesharing strategy of Set For Current is revised in prompting.Through said method, the situation of having avoided the time of implementation section of the multistage timesharing strategy on the same port to clash has improved the reliability of present technique.
Certainly, according to actual needs, can consider only to dispose a default policy, come into force automatically after this default policy configuration is accomplished for some port.
Based on said method, present embodiment also provides a kind of final controlling element of HQoS strategy, and this device can be arranged on the server of service access side.Fig. 4 is that as shown in Figure 4, this device can comprise according to the structured flowchart of the final controlling element of the HQoS strategy of the embodiment of the invention: detection module 42, first Executive Module 44 and second Executive Module 46 describe in the face of this structure down.

Embodiment two
Present embodiment is that example describes the foregoing description and preferred implementation with the multistage strategy that tree structure is set at designated port.
As shown in Figure 3, HQOS has been applied in the network of number of different types.Can combine Fig. 1 and Fig. 3 to describe, the voice among Fig. 1, video and data traffic identify with priority, and this is at Level1, can dispose the for example WFQ scheduling of strategy of Level1, and the scheduling ratio of voice, video and data traffic is set; Be provided with different shaping values for each internal layer vlan at Level2 (the inner vlan among Fig. 1), the difference of the data based priority that internal layer vlan is identical is dispatched according to the strategy of level1; At Level3 (the outer vlan among Fig. 1) data flow has been carried out the shaping speed limit again, finally be applied to designated port, designated port can carry out further speed limit etc.A packet finds one's own QOS parameter through multistage coupling.
Embodiment three
The Inbound that present embodiment is bound the A port with the timesharing strategy that this one deck of Level3 among the embodiment two is set is that example describes, and based on this, present embodiment provides a kind of configuration and method for using of HQoS strategy, and this method realizes based on the equipment among the embodiment one.Fig. 8 is according to the configuration of the HQoS strategy of the embodiment of the invention three and the detailed process sketch map of method for using.Can be tactful in describing above " strategy " among Fig. 8 all refers to the Level3 of port binding, and do not represent lower floor's substrategy.This method may further comprise the steps:
Step S801 plans each time period according to the actual requirements through configuration module, disposes a plurality of HQoS strategies and default policy, gets into step S802 for the HQoS strategy, gets into step S805 for default policy.
Step S802, respectively each strategy is bound with port A assigned direction and correlation time section, get into step S803.
Step S803 if do not conflict with the tactful time period that port has been bound, then gets into step S806; If conflict is arranged, then get into step S804.
Step S804, prompt time has conflict, and the modification time section reconfigures, and gets into step S803 then.
Step S805 binds default policy and port A Inbound, gets into step S806.
Step S806 is saved in database with strategy after the configuration successful, gets into step S807.
For example; Strategy 1 bundling port A Inbound; Section time1 correlation time (9:00am-10:00am of every day), this is the first strategy of bundling port, the tactful time that gets into step S803 is judged; The time period of not conflicting with it, then the configuration of " tactful 1+time1+ port A Inbound " can successfully write database; Again with tactful 2 bundling port A Inbound; Section time2 correlation time (9:30am-11:00am of every day); When carrying out the judgement of step S803, find this moment to have and conflict, then can point out the modification time section with " the tactful 1+time1+ port A Inbound " that disposed tactful time.Revise time2 (10:00am-11:00am of every day), passed through the time conflict monitoring, the configuration of " tactful 2+time2+ port A Inbound " is write database, by that analogy.
Step S807, the time supervision module is monitored, and detects whether to arrive the related time period of timesharing strategy, if then get into step S808; If, do not get into step S810.
Step S808, the time supervision module is monitored, and detects whether to have arrived the timesharing strategy starting point of related time period, if then get into step S811; Otherwise get into step S809.
Step S809, the time supervision module is monitored, and detects whether to have arrived the timesharing strategy end point of related time period, if then get into step S812; Otherwise continue to detect, again execution in step S809.
Step S810, current system time through driver module sending flow rate administration module, get into step S813 with the HQoS default policy not in each related time period.
Step S811, current system time can mate the time period related in the timesharing strategy, and corresponding timesharing strategy through driver module sending flow rate administration module, is got into step S813.
Step S812, system time arrives certain time period end point, time supervision module trigger event; The command driven module is deleted overdue HQoS timesharing strategy; Again according to the result of determination of time module, issue other timesharing strategy or default policy then, promptly get into step S807.
Step S813, in the time of after system time is in certain time period starting point, before the end point, time supervision module trigger event, update strategy, the flow of port A assigned direction carry out service quality according to the current HQoS of coming into force strategy and guarantee.
Generally speaking, step S801-S805 realizes through configuration module.Step S806 depends on DBM, and the judgement time-dependent of step S807-S809 is in the time supervision module; Step S810-812 realizes that at driver module step S813 has described through the traffic management module and finally realized the service quality assurance by the current HQOS of coming into force strategy.
Example then: current system time is 9:30am when supposing the configuration completion, and the time supervision module was found in the time period of time1, then at port A Inbound distributing policy 1.Arrive 10:00am when the time, this is the crash time of time1 and time2, and the time supervision module triggers upgrades the incident that drives, and command driven issues efficient strategy 2 with the deletion that is provided with of overdue tactful 1 pair of traffic management module.Arrive 11:00am when the time, promptly during the end point of time2, the time supervision module triggers upgrades the incident that drives, and command driven is deleted from hardware overdue tactful 2.If do not dispose other timesharing strategies, then issue default policy and come into force.Time continues forward, as the 9:00am that arrives second day, has arrived the entry-into-force time of strategy 1, by that analogy.
Come into force similarly with a plurality of tactful timesharing, present embodiment can also be supported such realization: the substrategy support under strategy is related with the time period.Can be with reference to figure 3.This n of " level1 substrategy 1_1 "-" level1 substrategy 1_n " 1 straton strategy all can depend on level2 substrategy 1, and this n 1 straton strategy timesharing comes into force.Level1 substrategy 1_1 section correlation time timeL2_1, level1 substrategy 1_2 section correlation time timeL2_2 ... Level1 substrategy 1_n section correlation time timeL2_n.Need judge timeL2_1 during configuration; TimeL2_2 ... TimeL2_n does not overlap and these times should be contained in the time period t imeL2 that level2 substrategy 1 comes into force; Its upper level strategy should not conflicted and belong to the time period that is substrategy in entry-into-force time time period, could guarantee that like this this substrategy is applied.Need dispose a level1 acquiescence substrategy 1 at last, in the time that does not have the timesharing strategy, default policy comes into force.In like manner, also can comprise the level2 substrategy of a plurality of timesharing in level3 strategy, port can be bound the level3 strategy of a plurality of timesharing.
Configuration and method for using and equipment through above-mentioned strategy; The a plurality of HQoS strategies of port binding have been realized; The design that many tactful timesharing come into force is also supported the timesharing of substrategy under the strategy, has solved HQoS one port and can only bind a strategy; The demand of different period Different Strategies be can't tackle in the existing network, underaction and drawback easily used and safeguard.
From above description; Can find out; The present invention is employed in section effective time of timesharing strategy and carries out this timesharing strategy; Carry out the mode of the default policy be bound to this port in the other times section, make that designated port can related a plurality of strategies, thereby can select the current strategy that comes into force of this port according to the time period; And support the configuration substrategy of timesharing in the strategy, thereby strengthen the flexibility that HQoS uses, satisfy more complicated existing network demand.
Obviously, it is apparent to those skilled in the art that above-mentioned each module of the present invention or each step can realize with the general calculation device; They can concentrate on the single calculation element; Perhaps be distributed on the network that a plurality of calculation element forms, alternatively, they can be realized with the executable program code of calculation element; Thereby; Can they be stored in the storage device and carry out, and in some cases, can carry out step shown or that describe with the order that is different from here by calculation element; Perhaps they are made into each integrated circuit modules respectively, perhaps a plurality of modules in them or step are made into the single integrated circuit module and realize.Like this, the present invention is not restricted to any specific hardware and software combination.
The above is merely the preferred embodiments of the present invention, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.All within spirit of the present invention and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
