Topology monitoring implementation of network management system in TWAREN hybrid network

Abstract

TWAREN (TaiWan Advanced Research and Education Network) is a hybrid network composed of several types of network services including Layer1 (Light-path), Layer2 (VLAN, MPLS-VPN and VPLS-VPN), Layer3 (research networks peering and transit) and Layer7 (SSL VPN). To develop a network management system for such kind of hybrid networks, we must firstly be able to construct the physical network topology, therefore the logical network services can then be mapped and an accurate monitoring and alarming system can be possible. However the automatic physical topology discovery is extremely hard and complicated in the hybrid network. In this paper, we propose our preliminary design on automatically detecting the hybrid network physical topology in TWAREN.

The Design and Implementation of the Defender Cloud on TWAREN Backbone

“…As the TWAREN [1] network operating center, we have done various researches and developed network management solutions to increase the availability of the backbone network [2,3]. Meanwhile, we started to realize the unique value of network security solutions in the backbone network perspective.…”
