Abstract: Various arrangements for increasing a transfer rate of a data transfer via satellite are presented. A satellite gateway may set an accelerated set of communication parameters that control communication between the satellite gateway and the satellite terminal via the satellite and between the satellite gateway and the content source to an accelerated transfer rate between the content source and the satellite terminal. A first set of data may be transferred from the content source to the satellite terminal using the set of communication parameters. After transferring the first set of data, the satellite gateway may adjust the initial set of communication parameters to an adjusted set of communication parameters. The adjusted transfer rate can be lower than the accelerated transfer rate.

Abstract: A provisioning system receives network element information from a wireless communication network that characterizes a virtual network element. The provisioning system determines that the virtual network element is active and that a provisioning data link is not operational between the virtual network element and the provisioning system. The provisioning system determines a network address for the virtual network element. The provisioning system exchanges network signaling with the virtual network element using the network address to establish the provisioning data link. The provisioning system transfers provisioning data to the virtual network element over the provisioning data link.

Abstract: Some aspects and embodiments of the present invention provide effective mechanisms for provisioning virtual networks on communication networks. In particular some aspects and embodiments provide an effective mechanism for embedding a virtual network into a multi-layered substrate network which utilizes a different communication technology at each layer. One such example is an IP network overlaid over an optical network, such as an OTN network. Embodiments jointly determine the assignment of virtual nodes and virtual links. Assigning the nodes and links together can provide for a more optimal solution than assigning the nodes and the links separately. Some embodiments generate a collapsed graph which includes the optical network and the IP network in a single layer. Accordingly some embodiments jointly determine the assignment of virtual nodes and virtual links within such a collapsed graph, which can provide more optimal assignments than considering assignments within each layer separately.

Additionally, the data center may be configured to route all orchestration calls of a data center through the CS, such that the CS can ensure that references to local data and orchestrations are handled within the data center, while references to data and orchestrations of a different data center are suitably routed to be handled by a corresponding CS of the appropriate data center.

Abstract: Features are disclosed for caching network resources. A system determines whether a resource which does not contain an indication in its associated header that it is cacheable may nevertheless be cached. The determination may be based on observations of a number of requests for the resource over time and from a number of different requesting clients. In response to determining that the resource is cacheable, the system may cache the resource, and in some cases modify the cache control header of resource to facilitate caching. The system may insert fields into the header or otherwise modify the header so that the resource may be cached at a network computing provider, at a requesting client device, or at some other shared or private cache.
