	att_abstract={{The management of communications networks increasingly requires detailed  knowledge of network usage, acquired by direct measurement.  We report on  the design and implementation of a backend system for Trajectory Sampling,  a method for the consistent sampling of packets in transmission across a  network domain.  This Trajectory Engine collects trajectory samples and  stores them after appropriate preprocessing.  It provides a querying and  visualization tool to aid in traffic engineering and troubleshooting tasks. }},
