Self-managing systems able to dynamically re-configure with respect to time-varying workload mixes and changing system resource availability are of growing importance in heterogeneous multicomputer environments. Advanced performance evaluation techniques are needed to induce and assess the impact of such re-configurations where guaranteeing timeliness of reconfiguration activities is particular...

Security is an obvious risk to active networking, as increased flexibility creates numerous opportunities for mischief. The point at which this flexibility is exposed, e.g., through the loading of code into network elements, must therefore be carefully crafted to ensure security. The Secure Active Network Environment (SANE) architecture provides a secure bootstrap process resulting in a module ...

ii To Mom and Dad, for everything. iii ACKNOWLEDGEMENTS Many people have made significant impacts in my life throughout my graduate school career. While I would be wont for space to individually thank each of the people who have touched my life during this time, I would like to express my heartfelt thanks to the following people for their great love, support, encouragement, and belief in me thr...

An active network allows applications to inject customized programs into network nodes. This enables faster protocol innovation by making it easier to deploy new network protocols , even over the wide area. In this paper, we argue that the ability to introduce active protocols ooers important opportunities for end-to-end performance improvements of distributed applications. We begin by describi...

We present some quantitative performance measurements for the computing power of Programmable Active Memories (PAM), as introduced by [BRV89]. Based on Field Programmable Gate Array (FPGA) technology, the PAM is a universal hardware co-processor closely coupled to a standard host computer. The PAM can speed up many critical software applications running on the host, by executing part of the com...

Self-performed arm movements are known to increase the tactile detection threshold (i.e., decrease of tactile sensitivity) which is part of a phenomenon called tactile suppression. Today, the origin and the effects of tactile suppression are not fully understood. Tactile discrimination tasks have been utilized to quantify the changes in tactile sensitivity due to arm movements and to identify t...

Active networking in an environment built to support link rates up to several gigabits per second prodices many challenges. One such area is that the total available processing power of a router is limited by the memory bandwidth and individual processing power of the router’s microprocessors. In this paper, we identify three key components, which combined promise an innovative active network s...
