Detailed Description
In the embodiment of the invention, logic network information is obtained, and a service resource range is determined according to the logic network information; acquiring a service type, and determining a networking configuration requirement corresponding to the service type from a logic network according to a preset service distribution rule; and distributing the service resources corresponding to the networking configuration requirements in the service resource range according to the networking configuration requirements.
The present invention will be described in further detail with reference to examples.
As shown in fig. 1, a method for allocating service resources according to an embodiment of the present invention includes:
step 110: acquiring logic network information, and determining a service resource range according to the logic network information;
here, a virtual network configured by an SDN controller is referred to as a logical network; the logical network information may be obtained by a service resource allocation system provided outside the SDN network, or a system in which the SDN controller is located, and the like, and the logical network information includes: network element roles, domain information of the network elements, ring information and the like; the SDN controller may configure services between an access layer, a convergence layer, and a core layer according to network element roles and different domains. The core concept of the SDN is that network functions, service functions, and network device hardware are decoupled, and hardware devices are replaced by virtual machines, and the deployment and migration of virtual machines make networking of a network complicated, and thus, it becomes important to automatically allocate service resources.
A logical network configured by an SDN controller is shown in fig. 2: the SDN controller sets 10 virtual devices on three servers, and respectively simulates devices of an access layer, a convergence layer and a core layer; the switch (acc, access)1, acc2, aggregation device (agg, aggregation)1, agg2 form the first access ring, acc3, acc4, agg1, agg2 form the second access ring, the two rings can be configured into adjacent rings or not configured into adjacent rings according to the service requirement; the aggregate layer equipment consists of agg1, agg2, autonomous system boundary router (asbr) 1 and asbr 2; asbr3, network edge router (npe) are core layer devices. After the virtual machine equipment is started, the virtual machine equipment does not have the network element roles, needs to be specified by an SDN controller, and is used as a logic network for creating two-layer and three-layer services after being specified; services can be configured on the devices, and corresponding service resources are needed when the services are configured; the equipment can be used as the starting point of the service;
after the logical network information is acquired, a service resource range can be determined according to the service type which can be borne by the logical network; the process of determining the service resource range can be predetermined before configuring the service, and can also be dynamically adjusted after configuring the service; the range of the service resource can be a range of some parameters used by the two-layer service and the three-layer service, and other parameters to be distributed can be added according to subsequent needs; the service resources comprise: BGP community-born attributes, RD, RT, tunnel number range, VCID, etc.; generally, the service resource data may also be configured into different formats, including a digital type, an Internet Protocol (IP, Internet Protocol) type, and the like, a system number + a digital type, and the like; these traffic resources determine the differentiation of traffic, the routing table composition of routers and dominate the data flow.
In practical application, a service resource pool can be established for the service resources within the determined range, the required service resources are extracted from the service resource pool, and the subsequently recovered service resources can also be put back to the service resource pool.
Step 120: acquiring a service type, and determining a networking configuration requirement corresponding to the service type from a logic network according to a preset service distribution rule;
here, a service allocation rule may be preset, and a corresponding networking configuration requirement may be set for each service type; the service type refers to a network function that requires a logic network to implement, such as a Long Term Evolution (LTE) service, a three-layer routing service, and the like; the service type required to be configured by the logic network can be obtained through external service configuration equipment; the networking configuration requirements include: the networking needs network layer number, network elements, rings formed by the network elements, routing relations among the rings, routing relations among the network elements and the like. For example, the three-tier traffic type is LTE traffic or government-enterprise type traffic; whether the service is to the core network or the asbr device; the second layer Service is Virtual Private line Service (VPWS) Service or Virtual Private LAN Service (VPLS); whether the equipment of the first access ring and the equipment of the second access ring need private network routing intercommunication or not; whether the acc equipment in the access ring and the agg equipment of the convergence layer are communicated by the route or not; whether the acc equipment in the same access ring can be communicated by a route or not; the digital type or the IP type when the service resource format is adopted; after the rules are formulated, the rules can be templated, so that the subsequent calling is convenient, and the subsequent use can be performed without repeated formulation due to more rules;
specifically, after the service type is determined, the configuration requirement of the networking is determined in the existing logic network according to the preset service distribution rule; acquiring roles of network elements, domains where the network elements are located and ring information, wherein the domains and the roles of the network elements determine the head and tail nodes of a service to be generated and the types of the service which can be communicated between the network elements, and the ring information determines the on-off of routes between the network elements and the flow direction of a data packet; the service allocation rule is flexibly specified by a user, can be dynamically adjusted, and can allocate networking configuration requirements to specific network elements.
Step 130: distributing service resources corresponding to the networking configuration requirements in the service resource range according to the networking configuration requirements;
here, after determining the networking configuration requirements, corresponding service resources may be allocated to each networking configuration requirement within the service resource range; for example, a three-layer service including acc1, acc2, agg1 and npe is created, and corresponding RD, RT, tunnel scope number, BGP community transmission attribute and the like are distributed according to network protocols and the like according to the rule contents of whether acc is communicated with a private network route, whether acc and agg are communicated with a private network route, whether the acc has a private network route at an npe side and the like in the service distribution rule; the service resources can be distributed according to a selected service resource format;
after the service resources are acquired, the service resources are encapsulated into the whole service and are issued to an SDN controller for logic network networking; before being issued to the SDN controller, the method can also judge whether the service resource range and the networking information are changed or not, whether the network element role and the domain information of the network element are changed or not, and if the network element role and the domain information of the network element are changed, the network element role and the domain information of the network element need to be distributed again.
Preferably, a multithreading protection mechanism can be adopted in the allocation process, different threads are adopted to allocate service resources for multiple service type demands, multithreading is adopted to ensure that the allocation of the service resources of multiple service types is not repeated, whether the threads of the service resource pool are occupied or not is judged, and if the threads are occupied, the allocation is carried out after the threads are idle.
Preferably, before allocating the service resource corresponding to the networking configuration requirement, the method further includes: confirming available service resources, and allocating the available service resources to the networking configuration requirement; when no usable service resource exists, newly determining the service resource range; available service resources may be determined based on the service resource scope and the service resources already in use;
specifically, the specific process of determining the available service resources, as shown in fig. 3, may include:
step 1301: setting a service resource range;
step 1302: obtaining all service resources and used service resources according to the service resource range, if the available service resources are empty, returning the minimum value of all service resources, ending the process, if the available service resources are not empty, entering step 1303;
step 1303: searching whether the available service resources have breakpoints, if so, returning the breakpoints, ending the process, and if not, entering a step 1304; here, the breakpoint refers to discontinuity of service resources caused by using, recovering, and the like of the service resources in the service use process; if the condition of discontinuity exists, the service resource can be used from the first service resource after the breakpoint;
step 1304: searching the minimum value of the used service resources, judging whether the minimum value-1 exceeds the range, ending the process, returning to the minimum value-1 if the minimum value-1 does not exceed the range, and entering a step 1305 if the minimum value-1 exceeds the range;
step 1305: searching for the maximum value of the used service resources, returning to the maximum value +1 if the maximum value +1 does not exceed the range, ending the process, if the exceeding range indicates that the service resource range set at this time is used up, needing to reset the service resource range for allocation, and returning to the step 1301; here, the reset service resource may be a service resource artificially left as redundancy when the service resource was previously set; or the service resources obtained by the subsequent service resource recovery; if all network resources such as network elements, rings, etc. in the logical network have been completely allocated, the service resource range cannot be reset.
Preferably, the used service resources can be recovered; in order to ensure the sustainability of business resource allocation, the business resources need to be recycled, and the recycling includes the following types of business resources: after deleting the service, the service resource corresponding to the released deleted service needs to be put back to the service resource pool; services existing in network management but not existing in the SDN controller correspond to service resources, and the service resources are asynchronous in data caused by various reasons and need to be uploaded and then recycled; and recovering invalid service resources caused by the damaged service existing on the SDN controller, wherein the part of service resources do not enable the service to be effective on equipment and cannot be redistributed, the part of service resources are marked as the invalid service resources in an Application (APP) database, after the invalid service resources are generated, the service cannot be deleted if the invalid service resources are generated, the service is deleted, the service recovery is executed, and otherwise, the part of service resources can only be treated as the invalid service resources.
Preferably, the service resource allocation method of this embodiment further includes displaying service resource usage status information; because the related service resources have various types and formats and the range can be dynamically adjusted, the service conditions of the service resources need to be displayed, so that the user can master the total service conditions of the service resources. The displayed content comprises: various ranges of current various business resources; the currently allocated service resource, the format of the service resource, the service type using the service resource, the service name, whether the service is valid, and the like; when the service resource is invalid, the user is required to process the service using the service resource, find out the reason why the service is invalid, whether the service is damaged or not synchronous, recycle the service resource after processing, and ensure that the service resource can be reused next time.
The positive effects produced by the present invention will be described in further detail with reference to specific examples below;
as shown in fig. 4, a service resource automatic allocation system may be newly added in an existing network, and the allocated service resource is sent to the SDN controller through a service invocation module, so as to establish a functional network corresponding to a service type requirement in the logical network, where the service resource automatic allocation system may be implemented by a system such as a server external to the SDN logical network, or may be implemented by a server device of the SDN logical network itself.
A logic block diagram of the service resource allocation method according to the embodiment of the present invention is shown in fig. 5, and includes:

step 520: the service resource range is designated, and the designation process can be before the service is configured or dynamically adjusted after the service is configured. The service resource range refers to some parameter ranges and formats to be used by the two-layer service and the three-layer service in this example, and other parameters to be allocated may also be added according to subsequent needs;
step 530: setting up distribution rules and making the distribution rules into templates, wherein the service distribution rules can be preset, and corresponding networking configuration requirements are set for each service type; the networking configuration requirements comprise the number of network layers required by networking, network elements, rings formed by the network elements, routing relations among the rings, routing relations among the network elements and the like; establishing the distribution rule into a template, and subsequently determining networking configuration requirements according to the template aiming at different service types;
step 540: distributing service resources, namely distributing corresponding service resources to corresponding networking configuration requirements;
step 550: the recovery processing of the business resources, the business resources used are recovered;
step 560: and displaying the service resource use condition, and displaying the service resource use condition to a maintainer by using an output device such as a display.
In step 540, the specific step of allocating the service resource, as shown in fig. 6, includes:
step 5401: docking external service configuration equipment, and designating an interface by a user; determining the service type according to the configured service; the service resource allocation system can select service resources according to types, and the service resources used by different service types are not the same; the interface information must be specified by the user;
step 5402: the service resource allocation system determines the networking configuration requirement according to a preset service allocation rule, and allocates service resources according to the networking configuration requirement: acquiring roles of network elements, a domain where the network elements are located, ring information and the like; the domain and the role of the network elements determine the head and tail nodes of the service to be generated and the types of the service which can be communicated between the network elements, and the ring information determines the on-off of the route between the network elements and the flow direction of the data packet; the service allocation rule is flexibly specified by a user, can be dynamically adjusted, and determines the allocation of the networking configuration requirement to a specific network element; for example, a three-layer service including acc1, acc2, agg1 and npe is created, and RD, RT, tunnel scope number, BGP community transmission attribute and the like are distributed according to the selected service resource format according to the rules of whether the accs in the service distribution rule are communicated with each other, whether the acc and the agg are communicated with each other, whether the acc has a private network route at the npe side, and the like;
step 5403: in the process of distributing service resources, a multithreading protection mechanism is adopted to ensure that the service resource distribution of multithreading and multiple service types is not repeated, whether the threads of the service resource pool are occupied is judged, and if the threads are occupied, the distribution is carried out after the threads are idle;
step 5404: after the controller right of the service resource pool is obtained, the service resource pool is updated, and the service resources which are available are judged by combining the specified range and the used service resources;
step 5405: entering a service resource recovery thread, judging whether a damaged service exists, if so, recovering the service resource used by the service, putting the recovered service resource into an available service resource, and returning to the step 5404; otherwise, go to step 5406;
step 5406: selecting available service resources from all service resources to distribute networking configuration requirements of the service;
step 5407: after acquiring service resources, packaging the service resources into a service, and preparing to issue an SDN controller;
step 5408: judging whether the service resource range, the networking configuration requirement, the network element role, the domain information of the network element and the like are changed, if so, returning to the step 5402 and then performing service resource allocation; otherwise, go to step 5409;

Preferably, the resource allocation module 73 may adopt a multithreading protection mechanism in the allocation process, allocate service resources to multiple service types by using different threads, adopt multithreading and ensure that the allocation of the service resources of multiple service types is not repeated, determine whether a thread of the service resource pool is occupied, and if the thread is occupied, wait for the idle state and then perform the allocation.
Preferably, before allocating the service resource corresponding to the networking configuration requirement, the resource allocation module 73 is further configured to: confirming available service resources, and allocating the available service resources to the networking configuration requirement; when no usable service resource exists, newly determining the service resource range; available service resources can be determined according to the service resource range and the used service resources;
specifically, the specific process of determining the available service resources, as shown in fig. 3, may include:
step 1301: setting a service resource range;
step 1302: obtaining all service resources and used service resources according to the service resource range, if the available service resources are empty, returning the minimum value of all service resources, ending the process, if the available service resources are not empty, entering step 1303;
step 1303: searching whether the available service resources have breakpoints, if so, returning the breakpoints, ending the flow, and if not, entering a step 1304; here, the breakpoint refers to discontinuity of service resources caused by using, recovering, and the like of the service resources in the service use process; if the condition of discontinuity exists, the service resource can be used from the first service resource after the breakpoint;
step 1304: searching the minimum value of the used service resources, judging whether the minimum value exceeds the range, ending the process, returning to the minimum value of-1 if the minimum value does not exceed the range, and entering step 1305 if the minimum value exceeds the range;
step 1305: searching for the maximum value of the used service resources, returning to the maximum value +1 if the maximum value +1 does not exceed the range, ending the process, if the exceeding range indicates that the service resource range set at this time is used up, needing to reset the service resource range for allocation, and returning to the step 1301; here, the reset service resource may be a service resource artificially left as redundancy when the service resource was previously set; or the service resources obtained by the subsequent service resource recovery; if all network resources such as network elements, rings, etc. in the logical network have been completely allocated, the service resource range cannot be reset.
Preferably, the service resource allocation apparatus provided in the embodiment of the present invention further includes: a resource recovery module 74, configured to recover the used service resources; in order to ensure the sustainability of business resource allocation, the business resources need to be recycled, and the recycling includes the following types of business resources: after deleting the service, the service resource corresponding to the released deleted service needs to be put back to the service resource pool; services existing in network management but not existing in the SDN controller correspond to service resources, and the service resources are asynchronous in data caused by various reasons and need to be uploaded and then recycled; and recovering invalid service resources caused by the damaged service existing on the SDN controller, wherein the part of service resources do not enable the service to be effective on equipment and cannot be redistributed, the part of service resources are marked as the invalid service resources in the APP database, after the invalid service resources are generated, the service cannot be deleted, if the invalid service resources are generated, the service is deleted, the service recovery is executed, and otherwise, the part of service resources can only be treated as the invalid service resources.
Preferably, the service resource allocation apparatus provided in the embodiment of the present invention further includes: the resource display module 75 is configured to display service resource usage status information; because the related service resources have various types and formats and the range can be dynamically adjusted, the service conditions of the service resources need to be displayed, so that the user can master the total service conditions of the service resources. The displayed content comprises: various ranges of current various business resources; the currently allocated service resource, the format of the service resource, the service type using the service resource, the service name, whether the service is valid, and the like; when the service resource is invalid, the user is required to process the service using the service resource, find out the reason why the service is invalid, whether the service is damaged or not synchronous, recycle the service resource after processing, and ensure that the service resource can be reused next time.
