10 Hinx Easy Backup application The Backup&Restore software chosen is Hinx Backup Easy version 2.1. The application features are: It is OpenSource It is fully Java-developed: multi-platform compliant with the technologies used for the control plane implementation Hinx Backup Easy is a simple but limited software. For our purposes, we identified the following extensions to be added and developed: File size calculation 14/01/

12 NSR and NSP modules The NSR module integrates the backup and restore application, supplying support for the ResourceRequest API specified in MUPBED deliverable D2.2 The NSR module implements the parameters translation logic NSR- NSP Interaction The NSP is deployed as web-service through the Apache Axis tool on Tomcat Web Server (SOAP/HTTP) NSP Interaction The communication between NSP and resource allocation module is implemented through XML/HTTP protocol 14/01/

15 Resource allocation and translation module (QoS Server) The QoS Server has a two layers functional architecture: Coordination Logic - Service Policy Decision Function (CL- SPDF): This software process is involved with the management of the requests coming from the application layer and forwards them towards the suitable Admission Control modules Admission Control Module Resource Admission Control Function (ACM- RACF): These modules perform Admission Control based on resource availability. They operate as a server for the CLs. Each ACM performs admission control for a specific area network RACF selection based on Context DB Information Each RACF performs Admission Control exploiting information available in a topology database 14/01/
