Mr. K. Marzullo of Stanford University Computer Systems
Laboratory will speak on ``Maintaining the Time in a
Distributed System''.
TIME: 3.30 PM
ROOM: MC 5158
ABSTRACT
To a client, one of the simplest services provided by a
distributed system is a time service. A client simply
requests the time from any set of servers, and uses any
reply. The simplicity in this interaction, however,
misrepresents the complexity of implementing such a
service. An algorithm is needed that will keep a set
of clocks synchronized, reasonably accurate with
respect to a standard, and able to withstand errors
such as communication failures and inaccurate clocks.
This talk will present a family of algorithms which im-
plement a distributed, self-correcting time service.
