Deployment Models Sample Clauses

Deployment Models. Three main deployment models can be considered when designing an SDN-based control plane: • A fully centralized model, with a logically single SDN controller with the whole view of the entire DCN • A hierarchical model, with a first layer of “child” SDN controllers responsible for disjoined portion of the DCN and a “parent” SDN controller which handle a more abstracted view of the whole DCN, obtained through the cooperation with the “child” controllers. This model could be adopted to handle very different technology domains through specialized “child” SDN controllers and requires only a north-south interaction between each child controller and its parent controller. Of course, this interaction can be recursive and involve several layers in the SDN controller hierarchy. • A distributed east-west model, with a set of peer SDN controllers, each of them responsible for a portion of the DCN and cooperating together with horizontal communications to achieve the whole control and management of the entire DCN. In general, the third model is very complex and particularly suitable to large scenarios characterized by a variety of trust domains where each network domain is controlled through proprietary protocols and a very limited amount of information can be exchanged outside the domain boundaries. The inter- controller communication can be regulated using protocols like BGP (Border Gateway Protocol) [RFC4271] or PCEP (Path Computation Element communication Protocol) [RFC5440]. However, this model is scarcely applicable to the intra-DC scenario, where a single DC provider is responsible for the whole DCN. The hierarchical model may be of interest due to the heterogeneous nature of the COSIGN DCN. However, the complexity and the time delays required by the inter-controller synchronization and communication (also in this case the PCEP is a reasonable candidate, with the extensions for the stateful and active mode [PCESTAT], [PCEINIT]) can be considered as strong limitation in highly dynamic scenarios like DCN environment. For this reasons, the COSIGN DCN Control Plane solution is based on the centralized deployment model, with a single SDN controller that maintains the overall view and control of the overall DCN. The specific characteristics of the different technologies available at the data plane are handled through dedicated plugins and abstracted with a powerful information model that allows for the application of unified functions and procedures in the SDN contro...

Deployment Models. Private cloud ‐ The cloud infrastructure is provisioned for exclusive use by a single organization comprising multiple consumers (e.g., business units). It may be owned, managed, and operated by the organization, a third party, or some combination of them, and it may exist on or off premises. Community cloud ‐ The cloud infrastructure is provisioned for exclusive use by a specific community of consumers from organizations that have shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be owned, managed, and operated by one or more of the organizations in the community, a third party, or some combination of them, and it may exist on or off premises. Public cloud ‐ The cloud infrastructure is provisioned for open use by the general public. It may be owned, managed, and operated by a business, academic, or government organization, or some combination of them. It exists on the premises of the cloud provider. Hybrid cloud ‐ The cloud infrastructure is a composition of two or more distinct cloud infrastructures (private, community, or public) that remain unique entities, but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load balancing between clouds).

Public Cloud is often non-geographically specific and can be accessed wherever there is an Internet connection.
