Abstract
Although active networks have generated much debate in the
research community, on the whole there has been little hard
evidence to inform this debate. This paper aims to redress
the situation by reporting what we have learned by design-
ing, implementing and using the ANTS active network toolkit
over the past two years. At this early stage, active networks
remain an open research area. However, we believe that we
have made substantial progress towards providing a more
flexible network layer while at the same time addressing the
performance and security concerns raised by the presence
of mobile code in the network. In this paper, we argue our
