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)
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)
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)
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)
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 requires(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)
