Effective Bandwidths

Vasilios Siris maintains a site, Large Deviation Techniques for Traffic Engineering, containing references, theoretical and experimental, on the application and evaluation of large deviation techniques, and in particular the many sources asymptotic and its related effective bandwidth definition. It also makes available software and traces, and has a list of FAQs on the s and t parameters.
A few papers:
