How the technical solution of the application and the technical solution of the application are solved with specifically embodiment below above-mentioned Technical problem is described in detail.These exemplary embodiments can be combined with each other below, for the same or similar general Thought or process may repeat no more in certain embodiments.Below in conjunction with attached drawing, embodiments herein is described.

Fig. 4 is the flow chart of cross-domain QoS method of adjustment that the embodiment of the present application one provides, method provided in this embodiment by Cross-domain QoS device executes, which can be synergist or other equipment, as shown in figure 4, the method for the present embodiment The following steps are included:

Step S101, the title and target bandwidth of the cross-domain QoS adjustable strategies template of target of business are received.

The title and target bandwidth of the cross-domain QoS adjustable strategies template of the target of business can be tenant in business granting or It inputs or selects when BOD.The title of the cross-domain QoS adjustable strategies template of target for example can be golden grade, silver-colored grade, platinum grade etc.. One business can define one or more cross-domain QoS adjustable strategies templates, and the cross-domain QoS adjustable strategies template of the target belongs to the industry It is engaged in the corresponding cross-domain QoS adjustable strategies template of one or more, each corresponding bandwidth area of cross-domain QoS adjustable strategies template Between, bandwidth section for example can be 10-20M, 20-30M etc..Bandwidth section includes discrete value or continuous interval value, tenant The target bandwidth of input must be in bandwidth section.If bandwidth section is discrete value, tenant can only input the discrete of agreement Bandwidth value.If bandwidth section is continuous interval value, tenant can input all values within this range.

Step S102, the access point to be adjusted corresponding service access path in combination VPN is determined.

The service access path includes the corresponding domain at least one segmentation VPN, each segmentation VPN, access to be adjusted Point is the access point of the business.The private line network that VPN is group purchase or lease is combined, combination VPN includes multiple segmentations The corresponding domain VPN, each segmentation VPN.When the business is by different access point access combination VPN, the corresponding business of business Access path is different, and service access path refers to the set for the segmentation VPN that business is passed through in combination VPN, service access path On include segmentation VPN number may for one or more.For some business, tenant be can specify in combination VPN All access points are adjusted, and also be can specify and are adjusted to some access point, if tenant does not specify access point, are write from memory Recognize and all access points in combination VPN are adjusted, the access point for needing to be adjusted is access point to be adjusted.To scheme For scene shown in 1, user, which can specify, is adjusted the access point of branch 1 and branch 4, also can specify to all branches Access point be adjusted, wherein the access point of branch 1 is TP8, and the access point of branch 4 is TP1, and branch 2 and branch 4 connect Access point does not mark.

Service access path includes a source and place, and the source in service access path is the access point of business, service access road The place of diameter can be access point, be also possible to the main domain of fixation of business.One business may have fixed main domain, it is also possible to not solid Fixed main domain.If business has fixed main domain, the place of the access path of business is the main domain of fixation of business.If business is not solid Fixed main domain, the place in service access path are access point (terminal of a teleservice).Main domain refers to that carrier combination VPN is end-to-end The domain of the single domain business of characteristic, specifying which single domain business game in single domain business game by the service definition stage is main domain industry Business strategy, the domain where main domain business game are main domain.

After determining the source and place in service access path, the reachable path from source to destination is determined, what reachable path passed through Domain, that is, business access path belonging to all TP.In example shown in Fig. 1, source TP1, Su Wei TP2, reachable path pass through 8 TP:TP8 ... TP1, TP7 and TP8 belong to domain A, and TP5 and TP6 belong to domain B, and TP3 and TP4 belong to domain F, and TP1 and TP2 belong to domain E, therefore, service access path pass through four domains: domain A, domain B, domain F and domain E altogether.

Step S103, include according in the title, target bandwidth and service access path of the cross-domain QoS adjustable strategies of target It is segmented the corresponding domain VPN, from least one the corresponding cross-domain QoS adjustment of the type of service policy template of the business obtained in advance In policy template, the single domain QoS configuration in the corresponding domain segmentation VPN for including on service access path is determined.

The cross-domain QoS adjustable strategies template of business can be good by the preparatory layout of synergist, alternatively, adding after operator's layout is good It is downloaded on synergist.At least one cross-domain QoS adjustable strategies template of each service definition, each cross-domain QoS adjustable strategies mould Plate includes single domain QoS adjustable strategies of the bandwidth section at least one domain, wherein different cross-domain QoS adjustable strategies templates Corresponding bandwidth section is different, and the domain that different cross-domain QoS adjustable strategies templates include is identical, but the single domain QoS in domain adjusts plan It slightly may be different.For example, business 1 defines two kinds of cross-domain QoS adjustable strategies templates: the golden cross-domain QoS adjustable strategies template of grade and The cross-domain adjustable strategies template of platinum grade, the corresponding bandwidth section of the golden cross-domain QoS adjustable strategies template of grade are 10-20M, platinum grade across The corresponding bandwidth section of domain adjustable strategies template be 20-30M, two kinds of cross-domain QoS adjustable strategies templates include three domains (such as Input field A, core domain B and metropolitan area C), but the single domain QoS adjustment plan in two kinds of cross-domain QoS adjustable strategies templates each domain for including It is slightly different.

Optionally, single domain QoS adjustable strategies include the QoS adjustable strategies of at least one of following rank rank: network element The QoS adjustable strategies of rank, the QoS adjustable strategies of interface level and the QoS adjustable strategies for flowing rank.Wherein, a network element packet Multiple interfaces are included, multiple and different streams, interface, that is, network interface can be carried on an interface.The other QoS adjustable strategies of network element level Suitable for the total interface on network element, synergist is that total interface defines identical QoS adjustable strategies.The QoS tune of interface level Whole strategy is only applicable to some interface, and synergist can define different QoS adjustable strategies for distinct interface.Flow the QoS of rank Adjustable strategies are suitable for stream, and the data on an interface may correspond to different stream, and synergist can be for different stream definition not Same QoS adjustable strategies.The present embodiment is merely illustrative, and single domain QoS adjustable strategies can also include the QoS tune of other ranks Whole strategy.

Optionally, the QoS adjustable strategies for entering direction and direction out in the same domain may it is different may also be identical.If same One domain to enter direction identical with the QoS adjustable strategies in direction out, then do not need to define into, go out direction, if the same domain It is different with the QoS adjustable strategies in direction out to enter direction, then need to define into, go out direction.Correspondingly, the other QoS adjustment of network element level Strategy includes: into the other QoS adjustable strategies of direction network element level and out other QoS adjustable strategies of direction network element level, interface level QoS adjustable strategies include: the QoS adjustable strategies and QoS adjustable strategies of direction interface level out into direction interface level, flow grade Other QoS adjustable strategies include: into direction stream rank QoS adjustable strategies and out direction flow rank QoS adjustable strategies.

In the present embodiment, by the title and target bandwidth according to the cross-domain QoS adjustable strategies template of target, from type of service In at least one corresponding cross-domain QoS adjustable strategies template of policy template, the cross-domain QoS adjustable strategies template of target is determined, be industry Role's label of the corresponding domain distribution TP of each segmentation VPN for including on business access path, when point for including on service access path When section VPN does not distribute role's label of TP in corresponding domain, synergist adjusts plan according to the single domain QoS in the corresponding domain segmentation VPN Slightly, the single domain QoS configuration in the corresponding domain segmentation VPN is determined；When the corresponding domain segmentation VPN is assigned with role's label of TP, association With device according to the single domain QoS adjustable strategies in the corresponding domain segmentation VPN and role's label of the TP of distribution, VPN pairs of segmentation is determined The QoS of the TP on domain answered is configured.To realize the flexible cross-domain QoS adjustment of intelligentized teleservice.

On the basis of embodiment one and embodiment two, the type of service plan of business is obtained before executing the above method Slightly at least one corresponding cross-domain QoS adjustable strategies template of template, the embodiment of the present application three provide a kind of cross-domain QoS adjustable strategies The method of combination of template, Fig. 6 is the flow chart for the cross-domain QoS adjustable strategies template method of combination that embodiment three provides, such as Fig. 6 institute Show, method provided in this embodiment the following steps are included:

Step S301, at least one the corresponding bandwidth section of business and business for receiving user's input are passed through at least One domain.

The domain that the corresponding bandwidth section of business and business are passed through is demand planning of the operator according to business, and passes through association Synergist, the possible difference in the domain in the corresponding bandwidth section of different business and process are supplied to the interface on device.

Step S302, the single domain QoS for generating each domain of business process respectively for the corresponding each bandwidth section of business adjusts plan Slightly, at least one cross-domain QoS adjustable strategies is obtained.

Wherein, the corresponding cross-domain QoS adjustable strategies in each bandwidth section pass through generating business for each bandwidth section Each domain single domain QoS adjustable strategies when, synergist can give birth to respectively first according to QoS data in collected each domain for each domain At the QoS adjustable strategies of at least one rank.For example, the corresponding bandwidth section of business includes following two section: 10-20M and 20-30M, the domain that business is passed through are three: input field A, core domain B and metropolitan area C, then first generate access for 10-20 bandwidth section Then the QoS adjustable strategies of domain A, core domain B and at least one rank in metropolitan area C generate access for 20-30M bandwidth section The QoS adjustable strategies of domain A, core domain B and at least one rank in metropolitan area C.The QoS adjustable strategies packet of at least one rank It includes: the QoS adjustable strategies of the other QoS adjustable strategies of network element level, the QoS adjustable strategies of interface level and stream rank.

It can also further be each domain optionally after the QoS adjustable strategies for generating at least one rank respectively for each domain Role's label strategy of TP is generated, role's label strategy of TP is used to indicate whether to distribute customized role's label for domain.

Step S303, type of service strategy is bound and is issued at least one the cross-domain QoS adjustable strategies generated.

On the basis of embodiment one is to embodiment three, the embodiment of the present application four provides a kind of determination in service access path Method, i.e. the present embodiment are the descriptions to a kind of specific implementation of above-mentioned steps S102 and step S202, and Fig. 7 is embodiment The flow chart of the determination method in the four service access paths provided, as shown in fig. 7, method provided in this embodiment includes following step It is rapid:

Step S401, judge whether business has fixed main domain.

Illustratively, it can indicate whether business has fixed main domain by the service definition in type of service strategy.Work as industry Business executes step S402 when having fixed main domain, when business does not fix main domain, executes step S403.

Step S402, using access point as source, fixed main domain is place, calculates the reachable TP from source to destination, is passed through up to TP It is segmented VPN and forms service access path.

Since business has fixed main domain, the adjustment of QoS influences the TP in the main domain from access point to fixation, it is therefore desirable to Access point is source, and fixed main domain is place, calculates service access path.

Can be determined as follows from the reachable TP of source to destination: from source, whether query source has direct-connected segmentation Segmentation VPN is included in reachable path set if there is direct-connected segmentation VPN in source by VPN, and by segmentation VPN in addition to source All TP are included in the TP set that do not search for, continue searching.Assuming that the direct-connected segmentation VPN in source in addition to source there are also two TP:TP2 and TP3, then judge whether TP2 and TP3 has direct-connected segmentation VPN respectively.

If source does not have direct-connected segmentation VPN, VPN is segmented by interdomain connection relational query next-hop, if there is next Segmentation VPN is jumped, then next-hop segmentation VPN is included in reachable path set, next-hop is segmented all TP in VPN in addition to entering TP It is included in the TP set that do not search for.The above method is carried out to all TP not searched in set, is obtained up to TP.Wherein, under One, which jumps segmentation VPN, refers to that TP refers to that TP is closed by business by other segmentations VPN, direct-connected segmentation VPN of link (Link) connection System connects (the segmentation VPN i.e. where the TP) with this VPN.

Step S403, using access point as source, using the termination TP of business as place, the reachable TP from source to destination is calculated, up to TP The segmentation VPN of process forms service access path.

Since business does not fix main domain, the adjustment traffic affecting of QoS all TP end to end, it is therefore desirable to The boundary point of business is source, place, calculates service access path, and the access point of business and the termination TP of business are the boundaries of business Point.

On the basis of example 2, the embodiment of the present application five provides a kind of method of role's label for distributing TP, i.e., originally Embodiment is the description to a kind of specific implementation of step S203 in embodiment two, and Fig. 8 is the distribution that embodiment five provides The flow chart of the method for role's label of TP, as shown in figure 8, method provided in this embodiment the following steps are included:

Step S501, judge whether business has fixed main domain.

Illustratively, it can indicate whether business has fixed main domain by the service definition in type of service strategy.Work as industry Business executes step S502 when having fixed main domain, when business does not fix main domain, executes step S503.

It step S502, is alternate allocation default role the label UNI and NNI of all TP on service access path.

Wherein, the default role label of first TP on service access path is UNI, it is assumed that on service access path altogether There are 4 TP, then role's label of 4 TP is followed successively by TP1 (UNI)-TP2 (NNI)-TP3 (UNI)-TP4 (NNI).

Step S503, default role label UNI is distributed for first TP on service access path, where being first TP Domain domain interface distribute default role label NNI, be service access path on other domains all TP distribute role's label NULL。

I.e. synergist is only that first corresponding domain segmentation VPN (also referred to as input field) on service access path is assigned with Default is not distributed in default role label, the corresponding domain other segmentations VPN (also referred to as forwarding domain) on the service access path Role's label, wherein NULL indicates that TP does not have default role label.

Step S504, when in the single domain QoS adjustable strategies in the corresponding domain segmentation VPN on service access path including TP Role's label strategy, and role's label strategy of TP be designated as domain distribute customized role's label when, be according to domain connection relationship It is segmented the corresponding domain VPN and distributes the customized role's label of TP.

Step S504 is optional step, if the role's label plan for the TP for including in the single domain QoS adjustable strategies in some domain It slightly indicates not distribute customized role's label for domain, then synergist does not execute step S504.Alternatively, operator is only service definition Default role label, is not the customized role's label of service definition, then synergist does not execute step S504.

Customized role's label is that such as have two domains A, B according to interdomain connection contextual definition, there is connection between A and B Relationship, then domain A can define role's label toward domain B: ab, domain B can define role's label toward domain A: ba. Illustratively, synergist is that the customized role's label of TP is distributed in the corresponding domain segmentation VPN according to such as under type:

The TP list in the corresponding domain segmentation VPN is obtained, the TP list in the corresponding domain segmentation VPN includes multiple TP, from segmentation A untreated TP is read in the TP list in the corresponding domain VPN, whether untreated TP deposits next-hop segmentation VPN, if not There are next-hops to be segmented VPN by the TP of processing, then is segmented VPN's from segmentation VPN to next-hop for the distribution of untreated TP one Customized role's label distributes default role mark if there is no next-hops to be segmented VPN by untreated TP for untreated TP UNI is signed, according to the method described above the successively TP list in the corresponding domain traversal segmentation VPN, until the TP list in the corresponding domain segmentation VPN In role's label of all TP be assigned.Wherein, next-hop segmentation VPN refers to that TP passes through other of link (Link) connection It is segmented VPN.

Fig. 9 is a kind of schematic diagram of a scenario of cross-domain QoS adjustment, as shown in figure 9, enterprise has branch 1 in the city A, is had in the city B There is branch 2, enterprise has purchased cross-domain enterprise's special line, which includes 5 segmentation VPN:VPN1 to VPN5, In, VPN1 corresponds to input field, and VPN2 corresponds to the domain ONT, and VPN3 corresponds to the domain IP CORE, and VPN4 corresponds to the domain OTN, the corresponding exchange of VPN5 Machine domain, service access path have passed through above-mentioned 5 segmentations VPN, and 10 TP:TP1 to TP10 are passed through in service access path altogether.The industry Corresponding cross-domain QoS adjustable strategies of being engaged in include: QoS adjustable strategies that TP1 is configured with stream rank, TP2 not speed limit, TP3/TP4/ TP7/TP8 does the other speed limit of port level, and TP5/TP6 does port rank and flows the speed limit of rank, and it is other that TP9 is configured with port level QoS adjustable strategies, TP10 are configured with the QoS adjustable strategies of stream rank.Operator has been the service design, and two cross-domain Qos are adjusted Policy template, it is entitled gold grade, adjustable bandwidth section be respectively [10M, 10M], [20M, 30M).

Cross-domain QoS method of adjustment mainly includes following two process: (1) layout process of cross-domain QoS adjustable strategies template； (2) decomposable process of cross-domain QoS adjustable strategies, above-mentioned two process are all completed by synergist.

Wherein, the layout process of cross-domain QoS adjustable strategies template, may comprise steps of:

(1.1) operator determines type of service, such as enterprise's special line, and determines the corresponding cross-domain QoS adjustment of type of service The title of policy template, such as golden grade.

(1.2) bandwidth span list is determined for cross-domain Qos adjustable strategies template.For example, determining two bandwidth sections: [10M, 10M], [20M, 30M), allow client to select bandwidth any one value between 10M or 20M-30M.

(1.3) the single domain QoS adjustable strategies in all domains are generated for each bandwidth section.For example, generating the two-way of the domain OTN QoS adjustable strategies are as follows: only include the QoS adjustable strategies of interface level.

(1.4) if needing to distinguish role's label of TP in single domain, role's label strategy of TP, role's mark of TP are generated It include the first instruction information in label strategy, the first instruction information is used to indicate whether to distribute role's label for the TP in the domain.For example, The QoS adjustable strategies of the TP1 and TP2 of input field are different, then generate the first instruction information, can also produce the class of role's label Type, role's label are, for example, default role label: UNI/NNI.

The decomposable process of cross-domain QoS adjustable strategies, may comprise steps of:

(2.1) tenant inputs or selects the title and band of cross-domain QoS adjustable strategies template in business granting or Bod Width values.

Illustratively, according to the title and bandwidth value of the cross-domain QoS adjustable strategies template of tenant's input, by cross-domain QoS tune Whole strategy is converted to the configuration of access point, if adjusting QoS for whole combination VPN, cross-domain QoS adjustable strategies are converted to The QoS configuration parameter of all access points under whole combination VPN.Such as adjustment branch 1 is the 21M of golden grade, then is converted to TP1 tune Whole is golden grade, 21M.

(2.2) using access point TP1 as source, using main domain as place, service access path is calculated.In scene shown in Fig. 9, business tool There is fixed main domain, wherein IP CORE is fixed main domain.

(2.3) TP1 is put into search set, the direct-connected segmentation VPN of TP1 is segmentation VPN1, and segmentation VPN1 is included in business and is connect Enter path.TP (i.e. TP2) will not be searched for being put into search set, it is direct-connected then to judge whether TP2 has by TP1 labeled as processed It is segmented VPN.It since TP2 does not have direct-connected segmentation VPN, searches next-hop and is segmented VPN, is i.e. segmentation VPN2.Segmentation VPN2 is included in industry Business access path, and the boundary TP3 of VPN2 is included in search set.Abovementioned steps are repeated, until reaching fixed main domain, are obtained To service access path are as follows: VPN1-VPN2-VPN3, the TP passed through on service access path is successively are as follows: TP1-TP2-TP3-TP4- TP5。

It (2.4) is then industry according to the first instruction information due to including the first instruction information in cross-domain QoS adjustable strategies template The TP being engaged on access path distributes role's label.Such as: TP1 (UNI)-TP2 (NNI)-TP3 (UNI)-TP4 (NNI)-TP5 (UNI)。

(2.5) determine tenant input bandwidth belonging to bandwidth section, such as the affiliated bandwidth section 21M be [20M, 30M), root The cross-domain QoS adjustable strategies template of target is determined according to the title and bandwidth section of cross-domain Qos adjustable strategies template, according to the TP in each domain Role's label, determine the QoS adjustable strategies of each TP in service access path.Such as TP1 belongs to input field, role's label is UNI can find the QoS adjustable strategies that TP1 needs to configure stream rank in the cross-domain Qos adjustable strategies of target, and TP2 is not configured QoS adjustable strategies.

(2.6) according to the QoS adjustable strategies of TP each in service access path, the QoS of each TP in service access path is determined Configuration.

(2.7) the QoS configuration of each TP is sent to corresponding controller.Illustratively, according to the controller in domain where TP The QoS configuration of TP is sent, such as TP1, TP2 belong to input field, the corresponding controller 1 of input field are found, by the QoS of TP1 and TP2 Configuration is sent to controller 1.Controller receives the QoS of TP with postponing, by the QoS configuration of TP be decomposed into network element level configuration distributing to Corresponding network element.
