2 2 Communication Standard VERICATION TEST BED

4 VERICATION TEST BED: Introduction The Lifecycle of the Communication Standard (CS) will be concluded by a dedicated Verification Test Campaign to demonstrate the adequacy and suitability of this standard for the intended applications. 4 A dedicated Verification Test Bed (VTB) is under development for this purpose, to test all the features defined for the CS and to evaluate end-to-end performances in a representative environment, including all the layers of the protocol stack. Comprehensive Design and Targeted Scenarios will be incrementally implemented for testing, both in open and closed loop conditions, thus providing a fully verified and tested Standard.

5 VERICATION TEST BED: Mission and Purpose The objective of the Verification Test Bed (VTB) is to provide the means for testing the Communication Standard features as finalized during ANTARES Phase B2. 5 The VTB will provide a representative and modular test environment for emulating and verifying the CS features at logical and physical level. The VTB will allow verification of CS features under realistic conditions and in full end-to-end scenarios, considering both layer-specific functionalities and end-to-end application layer performances.

6 VERICATION TEST BED: Mission and Purpose (cont d) 6 The CS features emulated in the VTB and relevant test capabilities of the facility are designed and implemented according to specific CS test cases, including the following test categories: Functional Tests Performance Tests Stressing Tests The test activities performed by VTB will provide technical confidence on important functional aspects and performance of Communication Standard, as well as clear inputs and evidence for its standardization

7 VERICATION TEST BED: Architecture 7 The VTB Architecture is designed to provide a realistic representation of the ANTARES functional elements as well as external entities. In particular, VTB will integrate and use: representative breadboards of User Terminals representative breadboards of Earth Station (GES) and Control Centre (NCC) realistic emulation of Satellite Physical representative implementation of full CS protocol stack representative emulation of involved s

20 VERICATION TEST BED: Current Status 20 The Architecture of Verification Test Bed has been defined during the VTB Specification Review process (completed in January 2013). Development and Procurement of relevant VTB Elements have been already started. This process is based on an incremental refinement of element requirements aligned with the incremental Communication Standard definition steps. The Verification Test Bed will be fully integrated by end of 2013 and Communication Standard verification campaign will start in January 2014.
