Nowadays each network management system (NMS) adopts
different methods for collecting network information and different
data structures. This makes NMS cooperation difficult,
especially in multi-AS wide area network management.
The current goal of the KANVAS (Knowledge base system
in wide Area Networks with general Versatility, Availability
and Scalability) project is to realize wide area network
management by constructing a knowledge base system in
networks. This paper discusses construction of a knowledge
base system in a single AS (Autonomous System) towards
the future wide area network management. This paper also
shows the design and implementation of the knowledge base
system that collects network configuration information from
OSPF and SNMP, and stores it as instances of our proposed
network ontology called Bonsai. Additionally, a prototype
application that accesses the stored knowledge was implemented.
The evaluation of basic performance and scalability
of the system was carried out using a real AS topology and
synthetic topologies and it was made sure that the prototype
application works correctly. As a result, this paper shows
that feasibility of the future wide area network management
that adopts the knowledge base system
