Embodiment
Bandwidth controlling schemes of the prior art, the hardware that has plenty of based on single face carries out Bandwidth Management, has plenty of the hardware constraints of casting aside, and carries out Bandwidth Management from the logic aspect separately, therefore exists various defectives.In order to guarantee that bandwidth resources are used appropriately, the present invention provides a kind of bandwidth controlling schemes in conjunction with the factor of physics networking structure and logic aspect.Below in conjunction with drawings and Examples, technical scheme of the present invention is described in detail.
Embodiment 1:
The band width control method that present embodiment 1 is provided is applied to comprise the route exchange device of many interfaces, such as router and gateway device; Please refer to Fig. 2, may further comprise the steps:
S1-1, carry out the territory according to physical set web frame docking port and divide, wherein, arbitrary territory comprises one group of inner joint and one group of external tapping, and each group interface number is at least one;
So-called interface (interface), indication all is a physical interface usually, the network interface of router or switch for example can provide the bandwidth of 100Mbps or 1Gbps.
In this step, interface is carried out territory (segment) division according to the physical set web frame.Such as, when the physical set web frame is that intranet a and intranet b are when being connected to the Internet network by route exchange device, just can be that this route exchange device creates two territories, i.e. the territory 2 of intranet a to the territory 1 of Internet network and intranet b to the Internet network.After create in territory 1, with the interface definition that connects intranet a is the inner joint in this territory 1, with the interface definition of the connection Internet of correspondence is the external tapping in this territory 1, just truly reflected the physical set web frame between intranet a and the Internet network: the message that sends from intranet a is via inner joint--〉and the external tapping routing forwarding gives Internet, and the message that sends from Internet is via external tapping--the inner joint routing forwarding is to intranet a.In like manner, after create in territory 2, with the interface definition that connects intranet b is the inner joint in this territory 2, with the interface definition of the connection Internet of correspondence is the external tapping in this territory 2, just truly reflected the physical set web frame between intranet b and the Internet network: the message that sends from intranet b is via inner joint--〉and the external tapping routing forwarding gives Internet, and the message that sends from Internet is via external tapping--the inner joint routing forwarding is to intranet b.
As can be seen, a territory is appreciated that the physical set pessimistic concurrency control that is made of inner joint and external tapping, and this model comprises a pair of or many docking ports; As an instantiation, the relation between interface and the territory sees also Fig. 3.In Fig. 3, territory 1 comprises two docking ports: Interface A and InterfaceB have constituted the inner joint in this territory, and Interface D and Interface E have constituted the external tapping in this territory; Territory 2 comprises a docking port: Interface C constitutes the external tapping in this territory, and InterfaceF constitutes the inner joint in this territory.
It should be noted that, in Fig. 3, input interface and output interface have relation one to one, but in actual use, it also can be the corresponding relation between group and the group, such as, from the message of InterfaceA and Interface B input, can Interface D and any one of Interface E send.
Simultaneously, for an interface, it may be the inner joint in a territory and the external tapping in another territory simultaneously, also may be the external tapping or the inner joint in two territories simultaneously.Be example with intranet a and b still, the interface that connects intranet b in the route exchange device is the inner joint in territory 2, but also can be used as the external tapping in territory between intranet a and the intranet b simultaneously.Physical interface is which end that belongs to the territory is determined by networking structure, is not the emphasis that this paper discusses.
S1-2, be that each territory formulates the territory band-width tactics;
Divide when interface and to finish, the interface total capacity in each territory is just decided so, therefore, can formulate the territory band-width tactics according to the hardware interface ability in this territory, considers thereby the logic aspect included in.
Preferable, be that an interface only belongs to a territory, the bandwidth upper limit of territory one end is exactly an interface bandwidth upper limit sum like this; Perhaps, not only belong under the situation in a territory, can dispose the territory bandwidth upper limit according to actual conditions by the system manager at an interface, such as, the bandwidth upper limit in territory under an interface belongs under the situation in two territories simultaneously, the one half-band width can be counted respectively.
In addition, because all there are two group interfaces in each territory, therefore formulating the territory band-width tactics for each territory can comprise: be each territory formulation territory permission bandwidth to external tapping direction and external tapping at inner joint on the inner joint direction respectively; In general, inner joint allows the hardware capabilities decision of bandwidth by external tapping to the territory of external tapping direction, and external tapping allows the hardware capabilities decision of bandwidth by inner joint to the territory of inner joint direction.
As can be seen, formulate the territory band-width tactics, can realize that the bandwidth between the different physics networkings is isolated, prevent that bandwidth from being abused, misapplying according to the interface capability in territory.Simultaneously, allow bandwidth to define total flow, the maximum available bandwidth restriction is provided by the territory by the territory.
Further, the territory band-width tactics can also be from addition stratification and the grain refined setting of logic aspect, and to guarantee the stability of session individuality, this will be described in follow-up embodiment 2～embodiment 6.
S1-3, when when an interface receives message, carry out bandwidth control according to the territory band-width tactics in affiliated territory, control then execution in step S1-4 by bandwidth, otherwise abandon this message;
According to the set territory band-width tactics of present embodiment 1, this step is specially under the identification utilized bandwidth on the current direction in territory and whether exceeds the territory and allow bandwidth, is then to abandon this message, otherwise execution in step S1-4.
As can be seen, by the message of bandwidth control, the current bandwidth sum of its shared bandwidth and this direction of territory, place can surpass default territory scarcely and allow bandwidth, make utilized bandwidth unlikely above interface actual tenability and cause network paralysis.
S1-4, will send to by the message of bandwidth control under another group interface in territory;
Specifically sending to which interface determines according to carrying out the definition of territory when dividing.Such as, divide if carry out the territory according to situation shown in Figure 3, then owing to have relation one to one between interior-external tapping, then the message that receives from an interface must be sent to its corresponding interface; Otherwise, if just-the external tapping group is corresponding, then can send to the interface in another group arbitrarily.
Preferable, when interface had been carried out the division of interface pipeline according to application, it sent destination and will further be limited, and this will inquire in follow-up embodiment 2 in detail.
As can be seen, the band width control method that provides by the embodiment of the invention 1, carrying out the territory based on the physical set web frame divides, both satisfied the hardware requirement of interface in the territory, be no longer dependent on management to single face, include the logic manage factor in consideration again, for further carry out fine granularity, multi-level Bandwidth Management provides wide space.
Because the angle of the technical scheme that embodiment 1 is provided whole hardware condition from the territory is for bandwidth control provides assurance; Therefore, on the basis of embodiment 1,, can realize multi-level, fine-grained Bandwidth Management by in the territory, carrying out the restriction of user and application bandwidth.Concrete, the embodiment of the invention 2～embodiment 4 further provides the bandwidth controlling schemes based on different application on the territory.
Embodiment 2:
Please refer to Fig. 4, present embodiment 2 may further comprise the steps:
S2-1, carry out the territory according to physical set web frame docking port and divide, wherein, arbitrary territory comprises one group of inner joint and one group of external tapping, and each group interface number is at least one;
S2-2, divide for interface carries out the interface pipeline, it is corresponding with an application that each interface pipeline is set;
Common, an interface can be divided into a plurality of interface pipelines (pipeline), and each interface pipeline can have different bandwidth, and the bandwidth sum of interface pipeline is an interface bandwidth.
Each interface pipeline can be used for corresponding different application when creating, for example point-to-point application (peer-to-peer is called for short P2P), IP phone (Voice over Internet Protocol is called for short VoIP) etc.Wherein, the interface pipeline is the transmission path that correspondence is used in the territory under this interface.Wherein, this interface pipeline can be unique transmission path that correspondence is used in the territory under this interface, also can be one of a plurality of transmission paths that correspondence is used in the territory under this interface, perhaps, when interface has one-to-one relationship in the territory, also can be one of corresponding unique transmission path of using or transmission path in the interface of place.As shown in Figure 5, be a schematic diagram that concerns between interface and the interface pipeline, wherein, interface A can be divided into four interface pipelines, is respectively: interface pipeline A1, A2, A3 and A4.Each interface pipeline all has a bandwidth value, and all are subjected to the restriction of this bandwidth value by the flow of this interface pipeline.
S2-3, be that each territory is formulated territory and allowed bandwidth on to external tapping direction and external tapping to the inner joint direction at inner joint respectively;
S2-4, on each direction, formulate second according to application message and allow bandwidth, described second allows the interface pipeline of bandwidth and respective application adaptive;
Wherein, this step indication has two kinds of situations with the interface pipeline is adaptive:
The first, the interface pipeline does not allow to surpass bandwidth constraints, then second allows bandwidth not limit greater than the bandwidth value of interface pipeline, thereby realizes real bandwidth isolation, prevents abuse and misuse;
The second, the interface pipeline allows to surpass bandwidth constraints, and then second bandwidth value that allows bandwidth can be made as greater than the interface pipeline limits, and when actual bandwidth exceeded in this interface pipeline, this interface pipeline can be used remaining bandwidth from other interface pipelines.
S2-5, when when an interface receives message, whether the utilized bandwidth under the identification on the current direction in territory exceeds the territory allows bandwidth, is then to abandon described message, otherwise execution in step S2-6;
By this step, realize that the online bandwidth of physical set isolates, guaranteed that physical interface is unlikely to block up.
Using utilized bandwidth under on S2-6, the current direction of identification and whether exceed the second permission bandwidth, is then to abandon described message, otherwise execution in step S2-7;
By this step, realized that the bandwidth of application level is isolated, guaranteed the stability of each utility cession bandwidth.
S2-7, will send to by the message of bandwidth control under in the corresponding interface pipeline of another group interface in territory.
As can be seen, present embodiment 2 is realized the multi-zone supervision of bandwidth control based on interface pipeline and territory, thereby realizes the multi-level bandwidth control based on hardware constraints and logical process.Especially, when allowing bandwidth to carry out refinement to be provided with, can realize more fine-grained bandwidth control, described in embodiment 3 to second.
Embodiment 3:
In order to realize fine-grained bandwidth control, in the present embodiment, formulate second according to application message and allow bandwidth to comprise: formulate a permission of using and connect sum, newly-built connection speed and/or connect bandwidth constraints etc.
Then, referring to Fig. 6, step S2-6 can specifically comprise among the embodiment 2:
Whether S3-6-1, the described message of identification are newly-built connection, are execution in step S3-6-2 then, otherwise carry out S3-6-4;
The permission whether S3-6-2, the described message of identification surpass affiliated application connects sum, is execution in step S3-6-6 then, otherwise carries out S3-6-3;
The newly-built connection speed whether S3-6-3, the described message of identification are used under exceeding is execution in step S3-6-6 then, otherwise carries out S3-6-4;
The connection bandwidth constraints whether S3-6-4, the described message of identification are used under exceeding is execution in step S3-6-6 then, otherwise execution in step S3-6-5;
S3-6-5, be that described message distributes and shares priority and business interface pipeline sign, this step finishes, and carries out subsequent step S2-7 downwards;
Wherein, in the present embodiment, shared priority can have a plurality of grades, and numerical value large level more is high more, represents that this message can obtain more bandwidth and guarantee in affiliated interface pipeline; Business interface pipeline sign is used on outgoing interface message sent into appropriate interface pipeline, for example the application interface pipeline of VoIP.
S3-6-6, abandon this message, produce the Bandwidth Management daily record.
Obviously, by above-mentioned steps, can realize fine granularity management for interface bandwidth.
Further, for fear of the influence that the interface pipeline is used the application message that has influenced script bandwidth abundance, can also distinguish the transmission rank of using message, as described in Example 4.
Embodiment 4:
On the basis of embodiment 3, in the present embodiment, formulate second according to application message and allow bandwidth also to comprise: formulate the committed rate, peak rate of this application etc.
When second allowed bandwidth to be provided with by foregoing, referring to Fig. 7, step S2-6 can specifically comprise among the embodiment 2:
Whether S4-6-1, the described message of identification are newly-built connection, are execution in step S4-6-2 then, otherwise carry out S4-6-4;
The permission whether S4-6-2, the described message of identification surpass affiliated application connects sum, is execution in step S4-6-10 then, otherwise carries out S4-6-3;
The newly-built connection speed whether S4-6-3, the described message of identification are used under exceeding is execution in step S4-6-10 then, otherwise carries out S4-6-4;

S4-6-5, be that described message distributes and shares priority and business interface pipeline sign;
Whether S4-6-6, the current message rate of identification exceed the committed rate of current application, are execution in step S4-6-7 then, otherwise execution in step S4-6-8;
Whether S4-6-7, the current message rate of identification exceed the peak rate of current application, are execution in step S4-6-10 then, otherwise execution in step S4-6-9;
S4-6-8, be first message with described packet labeling, this step finishes, and carries out subsequent step S2-7 downwards;
S4-6-9, be second message with described packet labeling, this step finishes, and carries out subsequent step S2-7 downwards;
S4-6-10, abandon this message, produce the Bandwidth Management daily record, finish.
In addition, second allows bandwidth can define abundant bandwidth parameter, such as comprising: allow the up average bandwidth of concurrent Total sessions, each session and descending session bandwidth etc.Its concrete control procedure and foregoing are similar, do not repeat them here.
When being provided with the second permission bandwidth in the above-described embodiments, please refer to Fig. 8, the step S2-7 among the embodiment 2 comprises:
S4-7-1, the business interface pipeline that carries according to described message identify, and determine the corresponding interface pipeline;
The packet labeling that S4-7-2, identification message carry is for the first message execution in step S4-7-3, for the second message execution in step S4-7-4;
S4-7-3, this message is sent to the direct transmit queue of the corresponding interface pipeline, this step S2-7 finishes;
S4-7-4, the shared priority of carrying according to this message are determined the corresponding priority level formation;
S4-7-5, this message sent to the respective priority formation of the corresponding interface pipeline.
Embodiment 5:
Further, among the foregoing description 1～embodiment 4 message is sent to after another group interface, can also comprise: according to the total bandwidth situation of described another group interface, scheduling message and transmission from interface queue.
Concrete, when interface can send message, the described message of scheduling from interface queue, and call the physics transmission; If physics sends successfully, then do not do any processing, if physics sends failure, then message reenters formation, waits for the next transmission cycle.Therefore, this step can be understood as the bandwidth shaping based on outgoing interface so that and the next-hop device of network carry out bandwidth adaptation.
Further, when message sent to the corresponding interface pipeline according to the step of step S4-7-1 to S4-7-4, in order to guarantee that the message in the direct transmit queue is preferentially sent, and the message of higher shared priority preferentially sent, and also comprises after the step 2-7:
S4-8-1, according to each interface pipeline of timer cycle poll, and calculate the message number that can send according to the interface total bandwidth;
S4-8-2, dispatch the message of the direct transmit queue under each interface pipeline;
S4-8-3, checking the message number that whether exceeds calculating, is then to finish, otherwise execution in step S4-8-4;
The priority query's message that has higher shared priority under S4-8-4, each interface pipeline of polling dispatching;
S4-8-5, checking the message number that whether exceeds calculating, is then to finish, otherwise execution in step S4-8-6;
Has low priority query's message of sharing priority under S4-8-6, each interface pipeline of polling dispatching;
That is, from priority at the highest level, and the like.Like this, can realize guaranteeing and the maximum available bandwidth restriction based on the minimum bandwidth of using in the territory, and the total bandwidth restriction that should use.
Embodiment 6:
The foregoing description 2～5 is described the technical scheme of carrying out bandwidth control from application point in detail.Preferable, be in the foregoing description 2～5 further based on the territory on different user carry out bandwidth control, to increase the level of Bandwidth Management, present embodiment provides a concrete implementation.
Please refer to Figure 10, may further comprise the steps at present embodiment 6:
S5-1, carry out the territory according to physical set web frame docking port and divide, wherein, arbitrary territory comprises one group of inner joint and one group of external tapping, and each group interface number is at least one;
S5-2, divide for interface carries out the interface pipeline, it is corresponding with an application that each interface pipeline is set;
S5-3, be that each territory is formulated territory and allowed bandwidth on to external tapping direction and external tapping to the inner joint direction at inner joint respectively;
S5-4, on each direction, formulate first according to user profile and allow bandwidth; Wherein, different users or user's group can dispose different band-width tacticses.A first permission bandwidth that has defined can be applied on the both direction of the current field, inner joint for example--〉external tapping, perhaps external tapping--〉inner joint, be used to limit the flow bandwidth that belongs to different two end interfaces of deriving from of a certain groups of users on the territory.If the two ends of this current connection in territory are respectively intranet a and Internet network, then can pass through this function, but the flow total bandwidth of the visit internet network of limited subscriber a1 is 2Mbps, and the flow total bandwidth of the visit internet network of limited subscriber a2 is 4Mbps.
S5-5, on each direction, formulate second according to application message and allow bandwidth, described second allows the interface pipeline of bandwidth and respective application adaptive;
S5-6, when when an interface receives message, whether the utilized bandwidth under the identification on the current direction in territory exceeds the territory allows bandwidth, is then to abandon described message, otherwise execution in step S5-7;
Whether the affiliated user's utilized bandwidth on S5-7, the current direction of identification exceeds first allows bandwidth, is then to abandon described message, otherwise execution in step S5-8;
In this step, the affiliated user of IP information searching of message be can pass through to extract, thereby the bandwidth abuse and the misuse of user class prevented.
Using utilized bandwidth under on S5-8, the current direction of identification and whether exceed the second permission bandwidth, is then to abandon described message, otherwise execution in step S5-9;
S5-9, will send to by the message of bandwidth control under in the corresponding interface pipeline of another group interface in territory;
S5-10, according to the total bandwidth situation of described another group interface, scheduling message and sending from interface queue.
It may be noted that above-mentioned steps 5-4 and step 5-5, step 5-7 and step 5-8 have described a preferable sequential relationship, promptly carry out the control of user class bandwidth earlier, carry out the bandwidth control of application level again.But it may be noted that, sequential relationship between step 5-4 and step 5-5 and step 5-7 and the step 5-8 is not absolute, can carry out the bandwidth control (being first execution in step 5-6) of application level earlier, just in a territory yet, use for specifying, continue the segmentation user.But because number of users is generally more, carries out the user at application and limit and realize that difficulty is bigger, therefore, preferable technical scheme is at the flow of designated user or user's group shown in present embodiment 6, continues segmentation and uses.
As can be seen, by the method that present embodiment 6 provides, in the territory, further realized the bandwidth control of user class; Therefore for arbitrary message, passed through the bandwidth control of territory level bandwidth control--〉user class successively--〉the bandwidth control of application level, thus realized the bandwidth controlled function of fine granularity, multi-level and various dimensions.Further described below by a specific embodiment 7.
Embodiment 7:
See also Figure 11, be the schematic flow sheet of present embodiment.
Suppose that we have created a territory 1, and distributed the interface at two ends for this territory, E0/1 is an inner joint, and E0/4 is an external tapping; Wherein, arrow line is represented the message flow on this territory 1, and the basic handling step of a message through this territory the time is as follows:
1) message inserts: message enters route exchange device from inner joint E0/1, determines that according to this interface the territory under the message is territory 1;
2) based on the Bandwidth Management in territory: allow bandwidth according to the territory that disposes on the territory, determine whether current message can pass through this territory; If the bandwidth deficiency then directly abandons this message, if bandwidth is enough, message is continued downward processing;
3) based on the Bandwidth Management of different user on the territory: on affiliated territory 1,, and, determine whether current message can pass through according to the difference of user's group based on the group of the user under the IP information searching; If the bandwidth deficiency then directly abandons this message, if bandwidth is enough, message is continued downward processing;
