Abstract
Differentiated Services (DiffServ), which are currently being
standardized in the IETF DiffServ working group, is a solution that
can provide different qualities of service to different network users.
DiffServ aggregates network packets at edge routers and forwards the
aggregated packets to core routers with different priorities.
In this paper, we propose methods using the SNMP framework for
monitoring edge-to-edge traffic aggregates in a DiffServ domain,
which consists of a set of DiffServ-enabled routers. In order to manage
each DiffServ router, we have analyzed the DiffServ MIB and instrumented
it in the router. Further, we propose monitoring behaviors of
edge-to-edge traffic aggregates by combining topology and performance
information from MIB II and DiffServ MIB. Construction procedures and
graphical representation of the edge-to-edge traffic aggregates are
explained in detail. We also extend our efforts to implement a DiffServ
domain monitoring system that monitors a set of DiffServ-enabled routers
and traffic aggregates between every edge router pair. We believe that
the proposed monitoring methods can serve as useful building blocks for
managing DiffServ networks.
