Simplifying Correlation Rule Creation for Effective Systems Monitoring

Event correlation is a necessary component of systems management but is perceived as a difficult function to set up and maintain. We report on our work to develop a set of tools and techniques to simplify event correlation and thereby reduce overall operating costs. The tools prototyped are described and our current plans for future tool development outlined.

Remote Code Browsing, a Network Based Computation Utility

Remote code browsing is a service by which an end user can select the location of a potentially useful piece of software and have the software fetched and installed on a virtual machine running on a remote server, such that the user may test the suitability of the software without having to install it on their own machine. This capability is made possible by a range of existing technologies combined in a novel way. This paper explains the motivation for code browsing, and describes how our current implementation works.

Client delegated control within an ASP infrastructure

Network programmability is a means by which some of the network operators control is ceded to the network user. While the research community recognizes that networks need to be more programmable to accelerate the speed with which innovation can be introduced, operators have been understandably loath to ‘open up’ their networks until there is some compelling reason to do so. We present a problem: the dynamic creation and modification of Service Level Agreements (SLA) in an Application Service Providers (ASP) infrastructure, which we argue can only be addressed by allowing clients some degree of programmability over that infrastructure. The entity that clients instrument is termed an Instant Corporation or ICorp and encapsulates server, network and proxying devices. We consider the issues involved in a ASP infrastructure which supports such client delegated control through a description of a working implementation called the ICorpMaker.
