With the convergence of computing, storage and network, especially
the maturity of data center technology, it becomes a trend that ISP
would like to deploy the computing and storage resources in the
network, so that the optimized resource utilization as well as the
value-added service can be provided. The data centers deployed in
the network can provide the runtime environment and resource to
optimize ICP services with various edge service proxies, such as CDN
servers and distributed Trackers. Meanwhile, based on data centers
ISP can provide all kinds of value-added services in the IP based
network. CNO (Core Network Overlay)is an ISP-controlled overlay
network constructed on top of the core network which is proposed as a
solution to large-scale data distribution in the Internet. It can
provide the transfer service for data distribution and switching in
the core network for the ICP and its edge service proxies. Because
the CNO nodes are trustworthy (controlled by ISP), stable and have a
simple economic model (without any participation of end users and
ICPs), various overlay based data distribution methods are easier to
be applied and standardized with CNO. This draft presents the
definition of the conceptions and terms about CNO.
