    Wireless data services have thus far been more promising than successful. We believe that future mobile information systems must be built upon heterogeneous wireless overlay networks, extending traditional wired and internetworked processing "islands" to mobile hosts over coverage areas ranging from in-room, in-building, campus, metropolitan, and wide-areas. In this paper, we describe a new wirele... View full abstract»

    For the last 26 years packet networks have insured low data loss for bursty data traffic with flow control which the author introduced in the ARPANET in 1969 and as a standard in X.25 in 1975. However, from the time ATM was introduced commercially around 1992 until now, flow control has been totally missing. The credit flow control used historically in packet networks was far too expensive at ATM ... View full abstract»

    Address traces are acquired typically in order to evaluate different cache organizations and memory hierarchy designs. Address traces have other uses, however. For example, traces can provide information about patterns of different types of memory accesses (e.g. reads versus writes). If the trace data includes time stamps, bursts of accesses can be detected and analyzed. This paper describes a ser... View full abstract»
