Latest Patents
Griffin's latest patents include a "Traffic engineering method with tunable inter-domain egress selection." This invention presents a flexible mechanism for routers to select the egress point for each destination prefix. The method allows network administrators to rank possible points of egress according to a metric, enabling them to achieve diverse goals such as traffic engineering and resilience to equipment failures. The patent discusses a weighting function that balances known hot potato routing against a fixed ranking scheme. The tunable inter-domain egress (TIE) selection has been applied to data from two different autonomous systems, solving distinct problems using integer-programming and multi-commodity flow techniques. Experiments conducted with traffic, topology, and routing data from two backbone networks demonstrate that TIE is both simple for routers and expressive for network administrators, making it practically applicable in traffic engineering.
Another significant patent is the "Method for tunable inter-domain egress selection." This invention outlines a flexible mechanism for routers to identify and rank multiple points of egress from an autonomous system. The method involves selecting the point of egress with the smallest rank and transmitting packets from a point of ingress via a path to the selected point of egress. The metric used is across various destinations and respective possible points of egress, incorporating configurable values to optimize routing decisions.
