Abstract:
1. A system comprising: a packet-switched network configured to carry at least one data transmission from a first endpoint to a second endpoint, said packet-switched network including: a first link utilization monitor including a processor and a memory and disposed between a first customer edge router and a first provider edge router in the first path, the first link utilization monitor configured to monitor a first link utilization rate associated with said first link and a second link utilization monitor including a processor and a memory and disposed between a second customer edge router and a second provider edge router in the second path, the second link utilization monitor configured to monitor a second link utilization rate associated with said second link, the link utilization monitors being configured to determine whether at least one of said first link utilization rate and said second link utilization rate is outside a range defined by a predetermined maximum utilization threshold and a predetermined minimum utilization threshold; wherein said at least one router is configured to reroute at least a subset of the at least one data transmission over said second link in response to said link utilization monitor determining that said first link utilization rate associated with said first link has exceeded said predetermined maximum utilization threshold, and said at least one router is configured to reroute said subset of the at least one data transmission over said first link based on a determination that said second link utilization rate is lower than said predetermined minimum utilization threshold.
