Abstract:
1. A method to reroute Internet Protocol traffic, the method comprising: detecting a network defect in a first communication path; receiving Internet Protocol traffic associated with a network user at a router, wherein the Internet Protocol user traffic is to be routed by the router over the first communication path; before rerouting the Internet Protocol user traffic over a second communication path different from the first communication path, and in response to detecting the network defect in the first communication path, buffering the Internet Protocol user traffic associated with the network user during a first time period having a first duration, the first duration being based on a first threshold defined by precedence bits included within the Internet Protocol user traffic, the first duration being specified by the network user; and adjusting the first threshold based on a number of cycles of network defects and associated network corrections determined to have occurred within a tracking period.
