Abstract: In one embodiment, a router includes processors and computer-readable non-transitory storage media coupled to the processors including instructions executable by the processors. The router may store at least one virtual prefix and an associated aggregation threshold. The router may register, with a mapping database of an overlay network, ownership of individual prefixes served by the router. The router may determine an amount of prefixes served by the router that are within an address space of the virtual prefix. The router may register, based on a determination that the amount of prefixes satisfies the aggregation threshold, ownership of the virtual prefix with the mapping database of the overlay network. The registration of the virtual prefix may cause ownership of one or more of the registered individual prefixes served by the router that are within the address space of the virtual prefix to be deregistered.

Abstract: In one illustrative example, network fabric policy data associated with an application, subscriber, and/or device may be received. Mobile network policy data that corresponds to the received network fabric policy data may be selected, based on stored policy mappings between a set of network fabric policy profiles of a fabric network and a set of mobile network policy profiles of a mobile network. A bearer or Quality of Service (QoS) flow of the mobile network may be established in satisfaction of the selected mobile network policy data. In addition, a packet filter of a traffic flow template (TFT) or a packet detection rule (PDR) may be generated and applied in order to direct IP traffic flows associated with the application to the established bearer or QoS flow for communication in the mobile network.

Abstract: Disclosed are systems and methods for providing policy selection in a software defined network. An example method includes registering, by an enterprise controller on an enterprise domain, in a shared mapping system on a service provider domain, one or more entries specifying one or more services for one or more classes of traffic to yield registered entries, reading, by a service provider controller, from the shared mapping system, the registered entries, posting, by the service provider controller, the one or more entries to one or more routing tables at a software-defined wide area network of the service provider domain and receiving a request, by a mobile node on the enterprise domain, of a specific service for a particular class of packets according to a classification of the particular class of packets based on a particular label defined in the registered entries for the specific service.

Abstract: The present technology provides a system, method, and computer-readable medium directed to dynamic implementation and management of multi-provider internet access featuring multiple access points across a multi-site overlay network fabric. An aspect of the technology is directed to the implementation of a common fabric-wide Virtual Network (VN) with a unique Internet Instance Identifier (Internet IID) that is dedicated to internet access traffic. Default access routes from multiple service providers (SP) are leaked into the VN with the Internet IID at exit points of the fabric using local Extranet policies. Internet-bound traffic generated from any point within the overlay fabric network is then redirected into the Internet IID, using remote Extranet policies. Internet-bound traffic, once in the Internet IID, follows the SP default access route(s) towards the exit points where SP specific access policies may be applied to the traffic which is then forwarded to the corresponding SP network.
