There is some more recent work done in this area. Some pointer are the following:
C. Fraleigh and F. Tobagi and C. Diot (2003).
Provisioning IP Backbone Networks to Support Latency Sensitive Traffic.
In: IEEE Infocom. San Francisco. Mar 2003.
K. Papagiannaki and S. Moon and C. Fraleigh and P. Thiran and F. Tobagi and C. Diot (2002).
Analysis of Measured Single-Hop Delay from an Operational Backbone Network.
In: IEEE Infocom. New York. jun 2002.

I hope this helps.
