Arrange unified interface protocol between all bottom hardware equipment and network controller, namely the manufacturer of dissimilar equipment will follow unified control unit interface specification, improves the compatibility of controller.
In one embodiment of the invention, the communication between core key-course and resource virtual level is by OpenFlow agreement or PCEP protocol realization.
In one embodiment of the invention, interface protocol can adopt OpenFlow agreement, also can adopt PCEP agreement.
Adopt the communication between OpenFlow protocol realization core key-course and resource virtual level as follows:
(1) each virtual forwarding unit needs to comprise a stream table, carries out searching and forwarding based on data flow.
(2) " resource database " module of network controller comprises multiple stream tables, in order to record link information and the information on services of each business.
(3) stream table is the kernel data structure that virtual forwarding unit carries out forwarding operation.Stream table comprises territory, packet header, counter, action.
OpenFlow agreement, can complete the function that core key-course obtains bottom hardware device resource status function, core key-course carries out operating function, adaptive different exchanging mechanism Network adaptation to bottom hardware equipment stream table.
Core key-course obtains bottom hardware device resource status function, and can be realized by two kinds of modes, first kind of way is the direct query resource state of core key-course, and the second way is bottom hardware equipment active reporting resource status.During the direct query resource state of core key-course, first initiate status inquiry command by OpenFlow agreement to bottom hardware by core key-course.After bottom hardware receives this order, inquiry local data base, sends to network core key-course by resource status situation afterwards.During bottom hardware equipment active reporting resource status, if network state changes, bottom hardware equipment Automatic inquirying local data base, sends to network core key-course by OpenFlow agreement by resource status situation afterwards.

Intel Virtualization Technology brings more restriction to communication network, needs the feature for Intel Virtualization Technology, formulates new routing algorithm and Resource Allocation Formula.According to OpenFlow agreement as interface protocol, routing algorithm and Resource Allocation Formula can be performed by the route in network controller and resource distribution module; According to PCEP agreement as interface protocol, routing algorithm and allocation protocol perform by the PCE being hung on network controller outward, are communicated between PCE with network controller by PCEP agreement.
PCE is through the development of long period, and technical mature and reliable, effectively can solve the problem that interconnects of heterogeneous network.
According to OpenFlow agreement as interface protocol, then need to consider that design route and resource distribution module are to solve the problem of cross-layer across path computing and territory scheduling of resource.
Network controller adopts centralized keyholed back plate, can obtain full mesh topology and the whole network resource database, and its cross-domain optimized algorithm relatively easily realizes, but needs to design corresponding optimized algorithm to reduce computation complexity.Because particle size differences between different layers network is comparatively large, cross-layer routing algorithm, by introducing business combing function, carrying out adaptation and convergence by varigrained business, efficiency utilization Internet resources, realizing the cross-layer scheduling of Internet resources.
Carrying out cross-layer across one of the key of path computing and territory scheduling of resource is Gains resources occupied information, makes service-aware module obtain the occupation condition of business in the following way.
After Business Stream arrives core key-course, service-aware module receives perception request, first whether has the information of this business in inquiry business registration form.If there is this business information, then return acknowledge message, this business is stamped label simultaneously.When the business of label again being detected, then no longer searching, avoiding the problem duplicating identification.If without this business information, then start service-aware flow process, to extract and analyze by taking the method for machine learning to business conduct, acquisition business takies situation to Internet resources, the relevant information of this business is registered in business registration form simultaneously.
Owing to adopting centralized keyholed back plate mechanism, a controller needs to control multiple bottom hardware equipment, under high dynamic network environment, mutual between upper-layer service and bottom-layer network resource and mutual very frequent between bottom hardware equipment and core key-course, therefore core key-course need information to be processed and event number huge, need to realize efficient, that stable, autgmentability is strong core key-course multi-service concurrent processing technology.Therefore, the realization of multi-service concurrent processing mechanism, needs to set about from software and hardware two aspect.In software, by arranging special data structure, reduce the complexity of Message Processing; At hardware aspect, by rationally arranging hardware flowing water, introducing hardware-accelerated technology, improving the efficiency of Message Processing.
