|Title:||Juno : a middleware platform for supporting delivery-centric applications|
|Abstract:||This paper proposes a new delivery-centric abstraction, which extends the existing content-centric networking API. A delivery-centric abstraction allows applications to generate content requests agnostic to location or protocol, with the additional ability to stipulate high-level requirements regarding such things as performance, security and resource consumption. Fulfilling these requirements, however, is complex as often the ability of a provider to satisfy requirements will vary between different consumers and over time.Therefore, we argue that it is vital to manage this variance to ensure an application fulfils its needs. To this end, we present the Juno middle ware, which implements delivery-centric support using a re-configurable software architecture to (i) discover multiple sources of an item of content; (ii) model each source’s ability to provide the content; then (iii) adapt to interact with the source(s) that can best fulfil the application’s requirements. Juno therefore utilises existing providers in a backwards compatible way, supporting immediate deployment. This paper evaluates Juno using Emulab to validate its ability to adapt to its environment.|
