Welcome to the SwitchWare page, describing research previously done on active
networking (a.k.a. Software Defined Networks, or SDN) by the Computer and Information Science
department at the University of Pennsylvania and Bellcore
(later Telcordia, and now
Active networks explore the idea of allowing routing elements
to be extensively programmed by the packets passing through them, now sometimes
referred to as Software Defined Networks (SDN). This
allows computation previously possible only at endpoints to be carried
out within the network itself, thus enabling optimizations and extensions
of current protocols as well as the development of fundamentally new protocols.
