Abstract: As the next generation of grid computing protocols centered
on web services and the Open Grid Services Architecture (OGSA) are
developed, the Peer-to-Peer community must determine how these
protocols can be used for building Peer-to-Peer applications.  Such
applicability is not immediately obvious since Peer-to-Peer systems
have significantly different properties compared to traditional
server-based grid systems. For example, Peer-to-Peer systems exhibit
different models of security and trust (machine user is typically also
the administrator), have different connectivity characteristics
(machine IP addresses may change due to mobility or firewalls/nats),
and different usage models (instant messaging, file sharing, and
collaboration). Because of these differences, Peer-to-Peer
applications are likely to require different capabilities in the
infrastructure than server-based grid applications. Yet despite these
differences, the shear numbers of desktop systems available today make
the potential advantages of interoperability between desktops and
servers into a single grid system quite compelling. Hence, the focus
of this document is on developing a set of requirements for OGSA to be
used to build Peer-to-Peer applications.
