Description
Technical field
The present invention relates to optical transfer network (Optical Transport Network, be called for short OTN) middle software defined network (Software Defined Networking, abbreviation SDN) controller technology, relating in particular to is a kind of architecture system and implementation method of the grade software defined network controller under multiple domain OTN network scenarios.
Background technology
Along with the cloud arrival of cybertimes, industry is had higher requirement to the development of the Internet.How to satisfy number of users, class of business, bandwidth demand etc. continuous growth, how to satisfy the user to dynamically the drawing in real time of service traffics, be the subject matter that the optical-fiber network tranmission techniques of future generation as the core bearing technology needs to be resolved hurrily; Be not difficult therefrom to find that as how the user is for leading, realization " on-demand service ", " plug and play " are the key factors that addresses the above problem, and also are the cloud features that the prerequisite O﹠M feature of optical-fiber network of future generation is optical-fiber network.
Under above-mentioned background, the technology path of software flexible control optical-fiber network of future generation more and more becomes industry in the focus of attention in optical-fiber network control technology field.Current, the SDN technology is generally considered along the desirable approach that holds this technology path.SDN is the word that Kate Greene creates, and proposes at about 2009, and principal character is as follows:
● on the technical development thinking, merged centralized and advantage distributed control technology, realized providing the intelligent direction transformation controlled to concentrated form with cloud to the upper-layer user from the intellectuality of paying close attention to the network equipment itself.
● on the form of equipment, realized control plane and transmitted separating of plane.
The main advantage that SDN is applied to the OTN technical field is embodied in:
● maximum advantage is to adopt independently controller technology, the service traffics control under the different exchange granularity technical conditions such as reply ODUk, ODUFlex, OCH.
● can satisfy the user to the demand of network editing, thereby occupation mode, mode of operation and marketing method at the network equipment realize flexibility, and can so that the user obtain the service function wanted at faster speed, need not the waiting facilities merchant these functions are brought in the proprietary product facility.
● SDN can bring the virtual management to optical network resource, and the network equipment scope of virtual management can cover whole OTN products.
● can bring into play centralized calculating advantage, realize the unified Optimized Operation to resource.
● the whole network resource information be can in time obtain, resource management and maintenance function are convenient to carry out.
As shown in Figure 1, the SDN network architecture that this figure generally admits take present industry is the basis, has showed the following SDN network architecture towards the OTN technology.
This framework mainly comprises: OTN application layer (OTN Application Layer), OTN network virtual layer (OTN Network Virualization Layer), OTN controller layer (OTN Controller Layer), OTN mechanical floor (OTNDevice Layer) be four levels altogether.Wherein,
The OTN application layer: allow the user according to self needs by writing simple control program, realize the purpose of definition OTN network model; The user can on the network model that self defines, initiate operation (comprising foundation, deletion, modification, the inquiry etc.) request to the OTN service connection.
OTN virtual level: be that user-defined all abstract network models are carried out finishing analysis, and finally be mapped to OTN the whole network network view.
OTN controller layer: the mapping relations of setting up the whole network network view and physical equipment network, the service request that issues according to the user, in the whole network network view, realize the Based Intelligent Control to service connection, and the service connection that will finally form configuration is issued in DXC on the corresponding device node, the OXC list item by OpenFlow or PCEP Extended Protocol.
The OTN mechanical floor: each device node is carried out the professional scheduling feature of this node according to self DXC, OXC list item record.
Under multiple domain OTN network scenarios condition, common way is to dispose respectively one or more OTN SDN controllers in each OTN territory.Its group-network construction is similar to shown in Figure 2.The main feature of the SDN network architecture of layout is as follows like this:
● the generation of network topology and maintenance
SDN controller in each territory only is responsible for setting up and safeguarding the mapping relations of this territory network view and physical equipment network; Between the SDN controller of same area the contents such as mapping relations of the network view in this territory, physical equipment network, network view and physical equipment network are not announced mutually.
● routing function
This territory SDN controller only participates in the path computing that this territory service path calculated or strode multiple domain service path part in this territory.Connect for cross-domain service, carry out determining of territory sequence by the mode of assignment.
● the business configuration function
This territory SDN controller only participates in the assignment that this territory service connection or cross-domain service are connected to part in this territory according to service path result of calculation; The content of configuration includes but not limited to the resources such as the label relevant with service connection, bandwidth.
For the control of cross-domain end-to-end service connection, need to solve the allocation problem that cross-domain service is connected to part between the territory by the RSVP-TE signaling protocol.
The above-mentioned network architecture in the few situation of the node number such as the number of OTN network domains in the less and network domains, still can satisfy as required use and United Dispatching to the whole network resource in simple network topology.But under the networking scene of complicated multiple domain, especially to tackle following cloud optical-fiber network to the demands such as United Dispatching of magnanimity resource, will run into the insurmountable problem of this single domain SDN controller network framework.
● the generation of network topology and maintenance
Can't form the mapping relations of the whole network network view and the overall physical equipment network of multiple domain, and then the Optimized Operation that can't connect for user-defined teleservice provides network topological information in the global network scope.
● routing function
The inter-domain routing that end-to-end cross-domain service connects can't connect the computing function that inter-domain path is provided for end-to-end cross-domain service according to the overall network topology view, so that can only obtain by manual assignment; Can't realize the whole network resource optimization algorithm truly.
● the business configuration function
Need to realize that cross-domain service is connected to the Reservation and allocation of part between the territory by operation RSVP-TE agreement between SDN controller, thereby impact connects treatment effeciency and the response speed of control to cross-domain service.
Under the batch operation condition that cross-domain service is connected, carry out Reservation and allocation, and asynchronous (the sending of next bar service connection PATH message of many service connection discoveries causing thus owing to adopt the RSVP-TE agreement between the territory, needn't wait until the RESV success response of a service connection) process of transmitting, with the success rate that reduces the multi-service attended operation.
Since the factors such as domain-to-domain link resource contention of intermediate field of process, will cause the failure of the discovery process of many homology chummages, non-homogeneous chummage service connection.
