Abstract: The present disclosure provides for a loop avoidance technique that implements an upstream neighbor check to detect any forwarding inconsistencies. When a message is received from a neighbor routing element, an upstream neighbor check is performed to determine whether the neighbor routing element is an upstream neighbor toward a content provider of a datastream identified in the message. If the check determines that the neighbor routing element is not an upstream neighbor, then a forwarding inconsistency is not detected. If the check determines that the neighbor routing element is an upstream neighbor, then a forwarding inconsistency is detected.

Abstract: In one embodiment, an apparatus includes one or more processors and one or more computer-readable non-transitory storage media coupled to the one or more processors. The one or more computer-readable non-transitory storage media include instructions that, when executed by the one or more processors, cause the apparatus to perform operations including receiving a user credential from a remote access client within a network and communicating the user credential to an authentication, authorization and accounting (AAA) server within the network. The operations also include receiving a user attribute from the AAA server and generating a contextual label based on the user attribute. The contextual label includes routing instructions associated with traffic behavior within the network. The operations further include advertising a control message, which includes the contextual label, to the remote access client.

Abstract: According to certain embodiments, a system comprises one or more processors and one or more computer-readable non-transitory storage media comprising instructions that, when executed by the one or more processors, cause one or more components of the system to perform operations comprising: receiving location data associated with a plurality of remote users accessing one or more existing remote access gateways that are located at one or more network locations; building a heatmap of user locations based at least in part on the received location data; and identifying, from the heatmap of user locations, at least one new network location in which to generate at least one new remote access gateway, or at least one existing network location in which to remove at least one of the existing remote access gateways.
