Patent ID: 8159968

Claim:
A method, comprising: measuring, at a network device, a first frame rate of frame-based transport based on a first frame size; measuring, 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; determining 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, where determining per frame encapsulation overhead in the frame-based transport comprises using a function that includes: encap_overhead = ( fs 2 * fr 2 * 8 ) - ( fs 1 * fr 1 * 8 ) ( fr 1 * 8 ) - ( fr 2 * 8 ) where encap_overhead is the per frame encapsulation overhead, fs 2 is the second frame size in bytes, fr 2 is the second frame rate in frames per second, fs 1 is the first frame size in bytes, and fr 1 is the first frame rate in frames per second; determining 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; and outputting the determined per frame encapsulation overhead and/or the determined total transport bandwidth associated with the frame-based transport.
