    • The taste of Pesto 

      Dillema, Feike W.; Stabell-Kulø, Tage (Research report; Forskningsrapport, 2001-08)
      The Pesto distributed storage platform is geared towards a computing model where private machines play a pivotal r ˆ ole. We argue that no centralized solutions are acceptable in its design and that it supports allocation of separate tasks to separate system components found in its target environment. Hence, Pesto separates trust from responsibility, storage from access control policy, and ...

    • TOS: A Kernel of a Distributed Systems Management System 

      Marzullo, Keith; Lauvset, Kåre J.; Johansen, Dag (Research report; Forskningsrapport, 2000-03-02)
      Distributed systems are becoming harder to manage, in part because the uses we put to distributed systems are rapidly changing. Hence, the software used to manage a distributed system needs to be flexible enough to accommodate these new uses. It also has to be secure enough to not allow unauthorized changes to be made to the system. We present a library and a kernel that supports the management ...
