This project proposes the development and performance evaluation
of mechanisms for the support of high priority users over public broadband TCP/IP networks (i.e., "the Internet").
Support for these types of users will enhance Internet service provider (ISP) revenue opportunities as well as support
activities of importance to national security and emergency preparedness. We have already produced significant results
on various mechanisms to support priority traffic this will extend that work over multiple links and multiple service
providers for application in the future Internet.The purposes in pursuing this particular work are as follows.
Distinctiveness - At this point, substantive work has not been conducted that focuses squarely on the needs of
priority users.
Societal Impact - This work will provide a significant benefit to society through support for high priority users.
Business communication opportunities can be expanded, property damage could be mitigated, and people's lives
could even be saved.
Long term viability - The ability to support priority users will always be an important problem, and new
problems will arise as new technological approaches are developed.
Interdisciplinary collaboration - Although not directly proposed in this project, this work will serve as a
foundation from which interdisciplinary work will naturally flow. Valuable work will be possible with high
priority users and research in medical, human factors, social science, governmental, and public relations
contexts.
It is important to note that the focus of this
project will be on priority users, more than on the traffic they generate or the services they are seeking to use.
Priority users may or may not expect high quality of service (e.g., low delay, high data rates) or applications that
place high demands on the network (e.g., interactive video). Without fail, however, all priority users will expect
network services to be available to them and to perform reliably, regardless of the state of the network or the context
in which it is operating (e.g., after a natural disaster).
This project will develop mechanisms for end-to-end treatment of priority users, both through networks that
explicitly support priority users and those that do not, and through both wireless and wireline networks. The following figure
illustrates paths traffic from priority users might take. For connection-oriented domains (e.g., stub networks),
resource reservation mechanisms will be developed that use integrated routing and connection admission control.
For Differentiated Services domains, per domain behaviors and traffic engineering guidelines will be developed that
address the specific traffic requirements of high priority users.
For those networks where priority users are given no special consideration (i.e., traditional best effort networks),
endpoint traffic control functions will be introduced and tested that allow hosts to fulfill traffic requirements on their
own. One example is through the use of collaboration with forwarding hosts to establish endpoint-selectable
alternate traffic paths.
