System and Method for Routing Internet Traffic Over Internet Links

摘要

An apparatus and method for IP transit is described. Embodiments include a platform for routing IP traffic in real time from at least one network user to a plurality of internet links. Embodiments further include assigning different ranks to different internet links based on network monitoring. In one embodiment, a system for routing internet traffic includes an internet route optimizer to generate routing instructions for incoming data packets using financial costs of routing data packets on the internet links, the traffic condition information corresponding to the internet links, and the types of data of the incoming data packets. In another embodiment, a method to generate a routing instruction to route an internet data packet uses financial costs of routing data packets on the internet links serving the end destination, traffic condition information of the internet links serving the end destination, and the type of data of the incoming data packet.

主权项

1. An apparatus comprising:
an internet router having (i) input ports to receive internet traffic from internet service providers, and (ii) output ports coupled to respective ones of internet links each of which is associated with a respective backbone provider, the router to couple selected input ports to selected output ports responsive to router instructions; and a processor coupled to the router to:
generate a first router instruction that identifies an output port connected to a fixed capacity bandwidth backbone provider that can receive traffic up to a first traffic level;generate a second router instruction that indicates that traffic in excess of the first traffic level is to be output to a usage-based bandwidth backbone provider that offers bandwidth capacity on an as-needed basis;generate a ranked list of bandwidth sellers among the service providers and the backbone providers from best to worst at least based on financial cost;determine if a traffic level is near a total fixed capacity for each input port; andif the traffic level is near the total fixed capacity, purchase additional bandwidth capacity from a best one of the backbone providers in the ranked list.
