Network architecture is always a hot topic of network research,
but application of network technology in the realworld usually
takes place a long way after it is created in a laboratory.
The recent explosive growth of the Internet has to lead
to several major issues regarding the network architecture.
The major issue related to the current architecture of
the Internet is the lack of QoS. This survey focuses on
network architectures of QoS for the Internet, along with
the following items: (1) current Internet-related issues,
(2) cache technology for improving the performance
of applications, (3) QoS technology for guaranteed service,
and (4) future active networks using an innovative architecture.
The current technology is described and the trend of network
architecture is discussed.
