Software updates typically require stop** and restarting an application, but many systems
cannot afford to halt service, or would prefer not to. Dynamic software updating (DSU) …

Ksplice allows system administrators to apply patches to their operating system kernels
without rebooting. Unlike previous hot update systems, Ksplice operates at the object code …

This paper describes an operating system (OS) called Theseus. Theseus is the result of
multi-year experimentation to redesign and improve OS modularity by reducing the states …

The past few years have seen a rise in popularity of massively parallel architectures that use
fat-trees as their interconnection networks. In this paper we study the communication …

Despite decades of research in extensible operating system technology, extensions such as
device drivers remain a significant cause of system failures. In Windows XP, for example …

Software evolves to fix bugs and add features. Stop** and restarting programs to apply
changes is inconvenient and often costly. Dynamic software updating (DSU) addresses this …

This paper presents POLUS, a software maintenance tool capable of iteratively evolving
running software into newer versions. POLUS's primary goal is to increase the dependability …

Methods, media and systems for responding to a Denial of Service (DoS) attack are
provided. In some embodiments, a method includes detecting a DoS attack, migrating one or …

K42 is one of the few recent research projects that is examining operating system design
structure issues in the context of new whole-system design. K42 is open source and was …

We propose a new approach for dynamic software updates. This approach allows updating
applications that until now could not be updated at runtime at all or could be updated but …
