QoS, pipeline web server, open KETA, adaptive content
With the development of high-speed backbone network,
more and more traffic load is pushed to the Internet end
system. Many kinds of Web server have been advanced to
increase the serving ability. In this paper, we propose a
pipeline architecture multi-thread web server open KETA
which divides the requests processing into several
independent phases. This architecture reduces parallelism
granularity and achieve inner-request parallelism.
Furthermore, a framework of integrating network QoS
with End System QoS is provided in open KETA. In this
QoS model, clients and objects with different degree of
importance are to receive differentiated service. When
server is overloaded, a new adaptive content delivery
method is applied to suspend requests refusing.
Experimental results show the capability of open KETA
and the effectiveness of the QoS model.
