New Framework and Mechanisms of Context-Aware Service Composition in the Future Internet

Abstract

The ongoing proliferation of new services, applications, and contents is leading the Internet to an architectural crisis owing to its inability to provide efficient solutions to new requirements. Clean-slate architectures for the future Internet offer a new approach to tackle current and future challenges. This proposal introduces a novel clean-slate architecture in which the TCP/IP protocol stack is decoupled in basic functionalities, that is, atomic services (ASs). A negotiation protocol, which enables contextaware service discovery for providing adapted communications, is also specified. Then, we present how ASs can be discovered and composed according to requesters' requirements. In addition, a media service provisioning use case shows the benefits of our framework. Finally, a proof-of-concept implementation of the framework is described and analyzed. This paper describes the first clean-slate architecture aligned with the work done within the ISO/IEC Future Network working group.

Prototyping a Software Defined Utility

“…WSDL is the most extended language used by web-services description, and offered a good solution for an easy and fast definition of the services' interfaces, besides bringing a standardized and well-known language easy to integrate with other service frameworks like OSGi [38]. Definition of services used in [6,7] was adapted for network services. However, it was defined generic to be adapted to application cases as well, as this one.…”

“…the modularization of smart grid functionalities and encapsulation into self-contained services facilitate the distribution of the smart grid intelligence, approaching the reasoning and decision process and helping to handle its critical constraints of latency on fault reaction. In this regard, the authors have extended the work conducted in [6] and present a new taxonomy of services ( Figure 5) for AMI security in this paper. This taxonomy classifies services into six different generic parameters: "Granularity", "Execution", "Scope" (application/network), "Purpose", "Usage" (mandatory/optional) and "Order" (dependent/independent), following the criteria selected in [6] and defining new sub-criteria based on the general and security requirements of a smart metering management [2,9,31,35].…”

All these criteria can be applied generically to any smart grid service, although the options shown in Figure 5 for "Purpose" criteria are limited to smart metering.…”

Contributions to the future media internet using service-oriented architectures

“…Details of these processes are also provided to understand the implementation introduced in section 7.5. The results of these work were published in [GP22] and [GP23].…”
