[e2e] Network level qos support for web services

[Stephen Suryaputra]

Hi,
 
Is there any latency requirements for transactions? I assume that web services are
mainly for that, not that I know anything about web services. Pardon if I made a
wrong assessment.
 
Cheers,

	Dear all, 

	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 
	services?
