2. Newtec at a Glance TEL IP TV What ? Satellite transmission How ? Make ground segment equipment 2
3. Targeted problem domain Consumer Broadband access, IP over satellite Network partitioning => groups of about 10000 consumers Each user => bandwidth profile (e.g. 10Mbit/s downlink speed) => traffic shaping to be done => 'Tellishape' (DUT) profile limiting (eg max 10Mbit/s) fair shaping and traffic distribution Satellite characteristics => 0.25s transmission delay (G-S-G picture) => acceleration desired => simulating this aspect requires 40 PCs 3
4. Test environment DUT: Tellishape (traffic shaper) => shapes 'accelerated traffic‘ Tellishape, Avalanche (Spirent test tool), client and server acceleration instances 4
5. Realization simulation of "real" field situations virtual wall offers efficient flexible test capacity Gradual increase possible: 25 machines (4 weeks) => 50 machines (2x2 weeks)"swapped in" Low learning curve Easy to operate : define once, run many Easy to attach other hardware (test HW, DUT, ..) test infrastructure needs varies over time => own acquisition of such platform not justified scalability issues in own SW found and corrected 5
