System and method for managing bandwidth usage rates in a packet-switched network
A computer-implemented system is disclosed for managing bandwidth usage rates in a packet switched network. The system includes one or more servers configured to execute computer program steps. The computer program steps comprises monitoring bandwidth usage rate at a first provider interface, determining if bandwidth usage rate at the provider interface exceeds a bandwidth usage rate limit; and rerouting Internet traffic from the provider interface having bandwidth that exceeds the bandwidth usage rate limit to a second provider interface having available bandwidth capacity.
1. A system for managing bandwidth usage rates in a multi-homed network, the system including one or more servers having memory for storing computer program instructions and one or more processors coupled to the memory, the one or more processors configured to execute the computer programs instructions, the computer program instructions comprising:
retrieving bandwidth usage data from the multi-homed network relating to a plurality of provider interfaces;
identifying network prefixes that carry Internet traffic on each of the plurality of provider interfaces based on the bandwidth usage data;
probing the network prefixes identified to determine performance of each provider interface of the plurality of provider interfaces;
determining if bandwidth rates at the plurality of provider interfaces exceed bandwidth rate limits;
identifying a first provider interface of the plurality of provider interfaces that has a bandwidth rate that exceeds a bandwidth rate limit;
retrieving network prefixes and bandwidth usage data at the first provider interface;
identifying at least one candidate provider interface of the plurality of provider interfaces, based on the performance of each provider interface, having available bandwidth that may receive Internet traffic associated with the network prefixes retrieved;
analyzing probing results for the retrieved network prefixes to determine the network prefixes on the first provider interface that can be rerouted to the at least one candidate provider interface; and
announcing the retrieved network prefixes that can be rerouted in the multi-homed network.
2. The system of claim 1 wherein the computer program instructions comprises applying new routes on the multi-homed network in accordance with the retrieved network prefixes that can be rerouted.
