Abstract:

Example methods disclosed herein to reroute Internet Protocol traffic include, after detecting a defect in a first communication path for routing user traffic associated with a network user, causing a router to buffer the user traffic for a first time period having a first duration before causing the router to reroute the user traffic over a second communication path, the first duration based on a first threshold. Such example methods also include, after detecting correction of the defect, causing the router to continue to route the 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 user traffic over the first communication path, the second duration based on a second threshold, the first and second thresholds being adjustable based on a number of cycles of network defects and network corrections counted within a tracking period.
