Abstract: 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.

Abstract: A system measures, at a network device, a first frame rate of frame-based transport based on a first frame size, and measures, at the network device, a second frame rate of the frame-based transport based on a second frame size, where the second frame size is different than the first frame size. The system determines per frame encapsulation overhead in the frame-based transport using the first frame rate, the first frame size, the second frame rate, and the second frame size. The system further determines total transport bandwidth associated with the frame-based transport using the first frame rate, the first frame size, the second frame rate, the second frame size, and the determined per frame encapsulation overhead.
