Abstract:
1. A method to reroute Internet Protocol traffic, the method comprising: after detecting a defect in a first communication path for routing Internet Protocol user traffic associated with a first network user, causing a router to buffer the Internet Protocol user traffic for a first time period having a first duration before causing the router to reroute the Internet Protocol user traffic over a second communication path different from the first communication path, the first duration being based on a first threshold; after detecting correction of the defect in the first communication path, causing the router to continue to route the Internet Protocol user traffic over the second communication path for a second time period having a second duration before causing the router to revert to routing the Internet Protocol user traffic over the first communication path, the second duration being based on a second threshold, the first and second thresholds being adjustable based on a number of cycles of network defects and associated network corrections counted within a tracking period, wherein the first and second thresholds are defined initially based on precedence bits included within the Internet Protocol user traffic.
