end-to-end performance

[Bingxue Cai <bingxuec@cs.byu.edu>]

Hi all:

        Any one knows if there was a build-in function I could use
directly to trace the end-to-end performance such as BW, Packet Delay,
Jitter issue?

        I know I could get those data from trace-all file, are there any
better way to extract those data out however?

Thanx for the help.
