Monitoring, Aggregation and Filtering for Efficient Management of Virtual Networks
Virtual Networks are characterised as highly dynamic network environments, where topologies and nodes adapt rapidly to changes in user and service demands, user location and context changes, or resource constraints. This paper presents a rigorous assessment of an Information Management Overlay (IMO) suitable for monitoring virtual networks. The IMO system allows complex monitoring tasks to be performed in a scalable manner in order that the network manager can monitor the desired network properties in a way which is accurate, scalable, and low-bandwidth. The monitoring architecture is decentralised, not resource intensive (in terms of memory or CPU), and adaptable to a wide range of virtual topologies.
