Abstract: In one embodiment, an apparatus of a LISP environment includes one or more processors and computer-readable non-transitory storage media coupled to the one or more processors. The computer-readable non-transitory storage media include instructions that, when executed by the one or more processors, cause the one or more processors to perform operations including receiving an attestation token from a first component of the LISP environment. The operations also include encoding the attestation token using a LISP message format. The operations further include distributing the encoded attestation token with a LISP signaling message to a third component of the LISP environment.

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: This disclosure describes techniques and mechanisms for providing hybrid cloud services for enterprise fabric. The techniques include enhancing an on-demand protocol (e.g., such as LISP) and allowing simplified security and/or firewall service insertion for datacenter servers providing those services. Accordingly, the techniques described herein provide hybrid cloud services that work in disaggregated, distributed, and consistent way, while avoiding complex datacenter network devices (e.g., such running overlay on TOR), replacing and moving the functionality to on demand protocol enabled servers, which intelligently receive the required mappings as well as registers and publishes the service information to intelligently interact with the network.

Abstract: Techniques for dynamically adapting a router capacity to system needs in a network. The border router may receive a list of summarized prefixes for endpoint devices associated with the router from control-plane nodes. The router may store the list of summarized prefixes in memory of the border router. Once the router receives traffic that is destined for endpoint devices associated with the border router, it may determine that the destination address is included in the summarized prefixes. In some examples, the router may download complete prefixes from the control-plane nodes, and forward the traffic to the destination address indicated by the complete prefixes.

Abstract: In one illustrative example, a router may be configured to provide a plurality of virtual private network (VPN) instances for a plurality of VPNs associated with a plurality of IDs. Each VPN instance may comprise a forwarding table instance for storing a plurality of host-to-router mappings for the VPN. The router may be further configured to provide a virtual VPN instance for a virtual VPN associated with an ID of a remote extranet VPN. The virtual VPN instance may comprise a map-cache for storing a host-to-router mapping for the remote extranet VPN. The virtual VPN instance has no corresponding forwarding table instance for user plane traffic associated with the remote extranet VPN, but rather serves as part of a control plane interface for control signaling associated with the remote extranet VPN. Accordingly, the router may provide multiple updates to host-to-router mappings in forwarding table instances of the VPNs in accordance with a change in the host-to-router mapping in the virtual VPN instance.

Abstract: Techniques are provided for a network mapping server device in a network to receive a connection upgrade message comprising information to establish a first data flow from a first endpoint that does not support multiple subflows for the first data flow according to a multipath protocol, where multiple subflows subdivide the first data flow across two or more network paths. The information in the connection upgrade message is analyzed in order to resolve network connectivity to determine potential network connections for at least two subflows of the first data flow to a second endpoint. A response message is sent comprising information configured to establish at least two subflows for the first data flow between the first endpoint and the second endpoint.
