Identifying and reacting to malicious or anomalous IP traffic is a significant challenge for network operators. Automated real-time responses have been simplistic and require followup actions by technically specialised employees. We describe a system where off-the-shelf 3D game-engine technology enables collaborative network control through familiar(More)
Darknets are increasingly being proposed as a means by which network administrators can monitor for anomalous, externally sourced traffic. Current darknet designs require large, contiguous blocks of unused IP addresses - not always feasible for enterprise network operators. In this paper we introduce, define and evaluate the concept of a greynet - a region(More)
With denial of service attacks and self propagating network viruses adding to today's network conditions, managing edge networks with the intention of providing a quality service requires vigilance by highly skilled network administrators. We believe the use of intuitive, interactive 3D representations of real-time network state information will improve the(More)
Darknets are often proposed to monitor for anomalous, externally sourced traffic, and require large, contiguous blocks of unused IP addresses - not always feasible for enterprise network operators. We introduce and evaluate the Greynet - a region of IP address space that is sparsely populated with 'darknet' addresses interspersed with active (or 'lit') IP(More)
This paper describes how a first person shooter (FPS) game engine can be leveraged for monitoring and control of enterprise IP data networks. Network administration can then occur in the following manner: network events (such as port scans or packets hitting a darknet) are translated in real time to various changes in the 3D game world state. Network(More)
— We take a closer look at the probable demand for bandwidth, presumed to motivate the deployment of new broadband access technologies. We construct plausible estimates of what a 'typical home' might need, given two different service provision scenarios-managed bandwidth and best-effort statistical multiplexing. We estimate a household of five people(More)
