The objective of the project is to implement a resource management system that performs bandwidth allocation at administrative domain level independent from the satellite network Network Control Centre (NCC).
SENSIBLE’s target is to supply the SATCOM market with a service capable to distribute dynamically the satellite bandwidth and manage the quality of service for a set of users within the same administrative domain, to which a fixed amount of bandwidth is assigned from the satellite operator. SENSIBILE will be able to detect the user’s needs (in term of bandwidth for the activated services) and shape the traffic between the terminals of the same administrative domain.
The service will provide three types of bandwidth utilisation with respect to the QoS:
The following figure shows the scenario for the maritime segment.
Since the project start, the key issues that we were addressed are:
ITS is currently present in the market of satellite services through a close collaboration with several satellite service providers (such as Eutelsat/Skylogic, CapRock and MTN). In addition, the company is present in the maritime market through its subsidiary SIRM, a company strongly focused on this market and specialises in providing solutions and value added services through VSAT broadband connectivity.
The product and service that will be marketed at the end of the project improves performance of satellite access to the internet, with a significant reduction in costs for professional ships and pleasure boats.
The components of the system are:
The following approach will be performed:
Problem study and analysis:
Service appliance development:
Service appliance validation and verification:
Service testing on field and dissemination:
The project started on the 22nd March 2010, the duration is 20 months.
Simulations performed with the Network Simulator 2 validated the concept and demonstrated the capabilities of this approach, with a responsive adjustment of the Sensible boxes to the upload rate configured by the Sensible Control Centre. At the same time the positive impact of the system has been demonstrated by simulations in presence of a large number of Sensible boxes and an unbalanced bandwidth allocation. Tests performed with real hardware and simulated or real satellite links confirmed the matching of internal classification of flows according to the configured priority, which was extensively tested and proved working correctly as expected.
