Juno: Reconfigurable Middleware for Heterogeneous Content Networking

Multimedia Content distribution is playing an increasingly prominent role in the Internet today, with a proliferation of diverse services and delivery mechanisms. Due to this increasing heterogeneity the management of next generation content networks is becoming increasingly complex. This paper presents Juno, a configurable component-based middleware designed to address the divergent nature of modern content networking. In Juno, functionality is separated into pluggable components that can be dynamically attached, detached and deployed, allowing the middleware to be specialised and adapted for different applications and environments. To demonstrate how functionality from (existing) content distribution networks can be realised through the middleware, an application operating over BitTorrent and Pastry has been developed using Juno. Through this, Juno is evaluated by looking at functional, non-functional and performance aspects of the framework.
