Abstract: The disclosure relates to technology for location-based services, and in particular, to geofencing. A computing device generates multiple circular shaped geofences to cover a geographic region defined by a polygon shaped geofence. The multiple circular shaped geofences are monitored to detect a current location of user equipment entering a boundary of any of the circular shaped geofences. Based on the detection, determining that the current location of the user equipment is within the polygon shaped geofence. A location based service is notified that the user equipment has entered the polygon shaped geofence.

Executing the instructions causes the processor to receive, from a second network element during a border gateway protocol communication session, a communications capabilities message indicating capabilities of the second network element, receive, from the second network element, an advertisement message indicating connections and accesses of a second domain controlled by the second network element, receive a request to route data between a source located in a first domain and a destination, transmit a first request message to the second network element to cause the second network element to compute a path segment through the second domain, and transmit a second request message to create a segment of an end-to-end tunnel between the source and the destination crossing the first domain and the second domain.
Abstract: Servicing a pseudowire communication across multiple Administrative Systems (AS) by components of packet data networks. A first Provider Edge (PE) router of a first AS receives a first Interior Gateway Protocol (IGP) message from a source PE router of the first AS that includes pseudowire data. The first PE router creates a first Border Gateway Protocol Link State (BGP-LS) message that includes the pseudowire data and transmits the first BGP-LS message to a second PE router of a second AS and intended for a destination PE router of the second AS. The first PE router then receives a second BGP-LS message from the second PE router that includes modified pseudowire data. The first PE router creates a second IGP message that includes the modified pseudowire data and transmits the second IGP message to the source PE router.
