“…Clark et al's 2003 SIGCOM [1] paper described a 'Knowledge Plane for the Internet' as operating in parallel to existing concepts of data, control, and management planes. However, a closer examination of this work reveals that it encompasses not only knowledge monitoring and analysis but also its use for the planning and execution of network control and management tasks, thus making it much closer in functional scope to Autonomic Communications.…”

Panel ReportThe panel opened with a question from the audience asking how the evolvability of Autonomic Communications (AC) and the stability of the resulting architectures and systems can be ensured. The panel responded stating that stability can not be regarded in terms of deterministic system configuration, but needs to be viewed in terms of behavioural stability. Thus we must tolerate a level of volatility but only within a well understood behavioural envelope that relates to specific autonomic tasks. In other words, we should focus on enforcing specific bounds on the adaptivity that selfmanaged systems may exhibit, rather than on achieving full behavioural determinism. With respect to the evolution toward and evolvability of AC, it was agreed that gradual changes were a real-life necessity. As a result we require ways to subdivide AC architectures into separate areas of concern that can be attacked, solved and deployed independently. However, there were no immediate suggestions for the lines along which such a separation would best be made. Preceding the panel, a poster presentation had included a synthesis of issues raised during the workshop in the form of a layered cube reminiscent of that used to explain broadband ISDN principles during the 1990's. It was observed that this synthesis served to show the potential complexity and inter-connectiveness of issues in AC. Reactions to this model, however, also hinted at the challenges in defining any clear architectural separations for AC given our current understanding of the field. It also spurred comments on the lessons that could be learnt by the failure of ATM to reach its technical potential due to a lack of flexibly in reacting to changing economic and market concerns.

“…As the networking community investigates the next generation Internet, it has become increasingly clear that a knowledge/information plane [10] that complements existing data and signalling planes is required. This third plane can be likened to a distributed database, where some of the content is raw data while other content is derived.…”

Abstract-Home networks have evolved to become small-scale versions of enterprise networks. The tools for visualizing and managing such networks are primitive and continue to require networked systems expertise on the part of the home user. As a result, non-expert home users must manually manage nonobvious aspects of the network -e.g., MAC address filtering, network masks, and firewall rules, using these primitive tools.The Homework information plane architecture uses stream database concepts to generate derived events from streams of raw events. This supports a variety of visualization and monitoring techniques, and also enables construction of a closed-loop, policybased management system. This paper describes the information plane architecture and its associated policy-based management infrastructure. Exemplar visualization and closed-loop management applications enabled by the resulting system (tuned to the skills of non-expert home users) are discussed.

“…More generally, a number of research efforts have begun to address some of the challenges in supporting Clark et al's [8] grand vision of a knowledge plane for large-scale, selfmanaging distributed systems. Examples projects that address the scalable monitoring of end-hosts and network paths, and the efficient support of query processing in the information plane include Sofia [45], IrisNet [14], PIER [35], Underlays [29] and iPlane [27].…”

Abstract-Many large-scale distributed systems can benefit from a service that allows them to select among alternative nodes based on their relative network positions. A variety of approaches propose new measurement infrastructures that attempt to scale this service to large numbers of nodes by reducing the amount of direct measurements to end hosts. In this paper, we introduce a new approach to relative network positioning that eliminates direct probing by leveraging pre-existing infrastructure. Specifically, we exploit the dynamic association of nodes with replica servers from large content distribution networks (CDNs) to determine relative position information -we call this approach CDNbased Relative network Positioning (CRP). We demonstrate how CRP can support two common examples of location information used by distributed applications: server selection and dynamic node clustering. After describing CRP in detail, we present results from an extensive wide-area evaluation that demonstrates its effectiveness.
