Embodiment
In order to make those skilled in the art person understand the present invention program better, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.Obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
As shown in Figure 1, the method comprises the flow chart of a kind of embodiment of the method based on SDN controller control message data service quality provided by the present invention:
Step S101: be message data distribution services quality identification, described service quality mark is used to indicate and the QoS parameter corresponding to each described message data;
Particularly, according to the priority of message data, can come for each message data distribution services quality identification.
Can further include in the embodiment of the present invention:
Being divided into system to retain described service quality mark in advance uses high quality-of-service identification section, system reservation default quality of service identification section and user can apply for service quality identification section three part.And SDN controller arranges corresponding service quality respectively to the given corresponding service quality mark of business datum.
The present embodiment can be that protocol massages and Systematical control message distribution system retain high quality-of-service identification section, is its data message distributing user application service quality identification section, for other message distribution system retains default quality of service identification section according to user's application; Can certainly according to message rule to data message distributing user application service quality identification section.
Such as, particularly, service quality identification field can be divided into three sections: 0 representative system and retain default quality of service identification section, and 1-55 representative of consumer can apply for service quality identification section, and 56-63 representative system retains use high quality-of-service identification section.0 to 63 is an example, also can use the numerical value such as 1 to 128 or 64 to 2048.Certainly, service quality mark is not limited to be divided into above-mentioned three parts, is also not limited to adopt above-mentioned distribution method, can distributes according to actual conditions.
Step S102: the path of process and capacity of equipment needed for data flow, for described message data designated identification method identifies;
Particularly, service quality mark can adopt vpt, dscp, vid or its be combined as described message data designated identification method, SDN controller issues rule makes data stamp as above message character.
It is to be noted, adopt vpt, dscp, vid or its be combined as message data designated identification method and be only a specific embodiment of the present invention, be not limited to adopt this several method, other can realize the method for identical function, and this does not affect realization of the present invention.
Step S103: described message data is forwarded by the QoS parameter corresponding to described service quality mark.
Particularly, QoS parameter corresponding to Message Service quality identification and capacity of equipment can issue rule, specify dispatching priority, bandwidth or other service quality behaviors, then described message is forwarded according to the dispatching priority of specifying, bandwidth or other service quality behaviors.
The method controlling message data service quality based on SDN controller provided by the present invention, by being message data distribution services quality identification, to indicate the QoS parameter corresponding to each message data; The path of process and capacity of equipment needed for data flow, for message data designated identification method identifies; Then the QoS parameter corresponding to being identified by service quality is forwarded this message data.The method controlling message data service quality based on SDN controller that the application provides, solve the shortcoming that in Traditional control service message quality method, configuration management is complicated, variation is difficult, very difficult harmonious, the overall situation can be carried out to the service quality of service message more neatly and control.
Method based on SDN controller control message data service quality provided by the present invention can specifically in system as shown in Figure 2, virtual machine wherein in server uses vswitch to connect, the mesh shape topological structure that the physical network of connection server forms for Layer 2 switch.SDN controller is a physical server or server cluster, also can be a virtual machine or one group of cluster virtual machine, and SDN controller can control vswitch and physical switches, and SDN controller does not draw in graph of a relation.
Further, when business datum is after network device processing, the service quality mark of message can be changed, the merging of service quality mark, conversion or dispersion can be carried out like this.Control in the another kind of embodiment of the method for message data service quality based on SDN controller provided by the present invention, be described the process of service quality mark conversion, as described in Figure 3, the method comprises its flow chart:
Step S201: issue rule according to tenant's rank and carry out the conversion of service quality mark;
The such as higher service quality of Dou Shi domestic consumer application, the switch of local vswitch or the first line of a couplet can use high service quality mark, and the switch on upper strata just needs to reduce service quality mark due to Bu Shi advanced level user.
Step S202: use arrangement to issue rule according to overall identification and carry out the conversion of service quality mark;
Such as can use vid identification service quality on vswitch, switch vid above has been used for distinguishing virtual net and has used, so need to be transformed to dscp identification service quality.
Step S203: issue rule according to upstream device ability and carry out the conversion of service quality mark;
Such as vswitch can only use vpt to go to map local dispatching priority and not support that dscp maps, and so needs SDN controller above, switch to issue rule and service quality mark is transformed to use vpt mark.
Step S204: issue rule according to Message Service quality identification and capacity of equipment and specify dispatching priority;
Step S205: issue regular nominated bandwidth according to Message Service quality identification and capacity of equipment;
Step S206: issue rule according to Message Service quality identification and capacity of equipment and specify other service quality behavior;
Step S207: message forwards by appointment dispatching priority and bandwidth.
Like this, by the use that service quality identifies, on network devices different dispatching priorities, different speed limits arranged to the business datum of different service quality mark or ensure bandwidth, can the service quality of service control message neatly, effectively utilize the bandwidth of network flexibly.
Such as, vswitch receives the message of VM, and according to the priority of user's application, SDN controller is its distribution services quality identification is 33; SDN controller needs the path of process on vswitch, use vpt to be the service quality of 5 identification datas according to vswitch ability and data; On the switch that vswitch connects, SDN controller issues rule and uses the service quality that dscp is 33, vpt is 5 identification datas; On object vswitch, SDN controller issues rule use vpt and is mapped to local dispatching priority, and in physical switches, SDN controller issues rule use dscp and is mapped to local dispatching priority and bandwidth.
Below the device controlling message data service quality based on SDN controller that the embodiment of the present invention provides is introduced, the device controlling message data service quality based on SDN controller described below with above-described control the method for message data service quality based on SDN controller can mutual corresponding reference.As shown in Figure 4, this device comprises the structured flowchart of a kind of embodiment of the device based on SDN controller control message data service quality provided by the present invention:
