Hi,

The updated and corrected draft of a document discussing delay bounds over Diffserv cloud is available at 
ftp://ftpeng.cisco.com/ftp/acharny/aggregate_delay_v3.ps 

Thanks again to Jim Roberts and Jean-Yves Le Bouldec for pointing out an error in the original version of the document. 

Feedback and comments will be appreciated.

Thanks,
Anna

What is clear is that the bound for a general topology is at least as bad as shown in the paper - but at the moment there is a possibility that it can actually be worse for some topologies.
