Abstract: An overlay network system includes point-of-presence (POP) devices each comprising a telemetry component, a billboard agent, and a packet routing daemon. The telemetry components generate latency measurements for the POP on which each is disposed. A centralized billboard service provides border gateway protocol (BGP) announcements and point-of-presence (POP) peering decisions to each of the billboard agent components. On each of the POPs, the path finding component and corresponding telemetry component, agent component, and routing daemon cooperate to transform the BGP announcements, peering decisions, and latency measurements into routing tables and link selections for packet streams routed through the POPs.

Abstract: Network devices that (a) test that GPS-clock enabled network devices have synchronized clocks, (b) identify non-GPS-clock enabled network devices with symmetric latencies as likely to be synchronized to GPS-clock enabled neighbor devices, (c) determine clock skews of remaining network devices not identified in (a) or (b) against the network devices identified in (a) and (b), and re-evaluate latencies of the GPS-clock enabled network devices, the non-GPS-clock enabled network devices, and the remaining devices based on the results of (a)-(c).

Abstract: A method including sending a media content to a target media destination through a first server and receiving a first response to the media content through a second server, where the first server is the intended receiver of the first response. A resulting triggering event is followed by the generating of a request to determine how to handle the triggering event. The request is received through a network routing control that comprises logic to generate a second response to the request. Next, the second response to the request is executed.
