QoS is an important issue for web services. The Internet still provides
best effort service. Without qos support from the network (Internet)how
web servicescan provide qos?
Differentiated services (Diffserv) has been proved successful in providing
better than best effor services in some large private networks. Although
it is still unknown how it will deliver the same in the global Internet.
For its successful large scale deployment in the global Internet diffserv
research community will have to invent some mechanisms which will attract
the companies that rely on the Internet for their critical business
operation. With companies more and more doing business on the web, now
comes the question of how diffserv can give better performance for their
web services ?
>From the beginning diffserv mechanisms (tagging, policing, scheduling)
have been designed for long lived tcp flows like voice, video etc. How
much diffserv is suited for short web traffic (flows that are less than
10KB)? How much a company which wants to reduce response tome for its web
services can rely on diffserv?
So does we need to tune diffserv for web services? If not then what is the
solution for a company which wants better service for its critical web
