FI-Ware KIARA – A novel QoS-enabled middleware

At a glance


Today, nearly any application depends on distributed and service-based computing of some sort. This is most apparent in the mobile and cloud computing areas but this trend is quickly affecting essentially all areas of computing. Despite this natural and comprehensive demand, most interestingly, there is to date no established middleware that provides dependable high-performance over a wide range of configurations and deployments, offers rich built-in QoS and Security features, while at the same time facilitating the development of diverse applications across a wide range of heterogeneous devices, infrastructures, systems, and domains.This mismatch between supply and demand became early and especially apparent within FI-WARE (, which is developing a large-scale, distributed, cross-technology Future Internet platform for a large set Use Case projects in different application domains.

The goal of KIARA is to provide a “Middleware for efficient and QoS/Security- aware invocation of services and exchange of messages”for the FI-PPP program and beyond.

KIARA aspires to improve the state-of-the-art in multiple ways:

  • Improves developer productivity and greatly simplifies application integration.

  • Dynamically and transparently selects the optimal communication mechanisms, protocols, and data representations to be used between two peers.

  • Embedded compiler dynamically at run-time generates highly optimized code that transfers messages directly from application data structures to the network.

  • Simple, high-level specifications of QoS/QoE and security requirements

  • KIARA uses a 'Secure By Design' approach for of the communication architecture
