Publication number: 20100002580Abstract: An approach is provided for auto-bandwidth adjustment of allocated bandwidth for a traffic tunnel over a network. A determination is made regarding a traffic load over the tunnel, where the tunnel meters traffic in accordance with the bandwidth allocation. A determination is made regarding whether the traffic load triggers an adjustment threshold, where the adjustment threshold is set to provide a desired headroom below the bandwidth allocation. And the bandwidth allocation is adjusted when the adjustment threshold is triggered to provide the desired headroom between the adjusted bandwidth allocation and the traffic load.Type: ApplicationFiled: July 7, 2008Publication date: January 7, 2010Applicants: Verizon Corporate Services Group Inc., Verizon Business Network Services.Inventors: Christopher N.

Publication number: 20100002724Abstract: An approach is provided for auto-bandwidth adjusting bandwidth allocations for traffic-engineered tunnels used to carry traffic along a network. Traffic over the tunnel is sampled at a first interval period and at a second interval period, where the second interval period is shorter than the first interval period. A determination is made as to whether the sampled traffic taken using the second interval period is greater than the bandwidth allocation, and the bandwidth allocation is adjusted upward based upon a determination that the sampled traffic taken using the second interval period is greater than the bandwidth allocation. Also, a determination can be made as to whether the sampled traffic taken using the first interval period is less than the bandwidth allocation, and the bandwidth allocation can be adjusted downward based upon a determination that the sampled traffic taken using the first interval period is less than the bandwidth allocation.Type: ApplicationFiled: July 7, 2008Publication date: January 7, 2010Applicants: Verizon Corporate Services Group Inc., Verizon Business Network Services Inc.Inventors: Matthew W.
