ADSL e Satellite, da separati in casa a conviventi consenzienti: il progetto COMBO Prof. Michele Luglio Università di Roma Tor Vergata Consorzio NITEL Milano, 16 Novembre 2017
Foreword Technology offers multiple technical solutions and standards NFC Bluetooth WiFi 2G/3G/4G Hyperlan WiMax Satellite HAPS Today we can state that it is possible to meet ALL the requirements but.... at the condition that we aim to just one There is no global end-to-end management Each one for himself Separated in the big family of telecommunications 2
Sometimes more than separated E sopra tutto, non si lasci uscir parola su questo avviso che le abbiam dato per suo bene; altrimenti... ehm... sarebbe lo stesso che fare quel tal matrimonio. questo matrimonio non s'ha da fare, né domani, né mai 3
The team OpenSky www.open-sky.it Prime contractor Nitel www.nitel.it Sub contractor Italian based company, main Italian distributor of INTERNET VIA SATELLITE. At the moment counts more than 17000 customers in Italy. Opensky is actually installing 20-30 new system per day and can count on more than 1500 installer in Italy. Opensky has also recently launched the offer for ADSL and VDSL connectivity. Opensky is in contact with Telecom Italia Wholesaler, Fastweb Wholesaler, Clouditalia. Consorzio Nazionale Interuniversitario per Trasporti e Logistica is an Italian research center. NITEL is participating with the Research Unit of Università of Rome Tor Vergata (UTV) which is a University group in particular specialized in satellite systems. Specifically, NITEL and the identified key personnel have a deep and comprehensive background on satellite communications, protocols, networking, Linux systems and embedded devices and have available complete satellite based simulation and emulation platforms. 4
Project description and objectives COMBO : Combination of an ADSL/VDSL with a Satellite Connection SBB: Smart Balancing and Back Up Main Benefits and Objectives: For the Customer Support all IP services Single IP Improve Performance User Experience Reliability Availability For the Operator Define a New product Improve Cost/Benefit Attract/approach new markets 5

Development Process Inputs from Opensky Feedbacks from Nitel Research Industry Algorithm Emulation Prototype in real network Deployment in real infrastructure with real users («Pilot») Production for Commercial Volumes Improvements ESA Project COMBO-SBB 7
What to improve When defining the algorithm we need to consider specific rules that allows Optimize performance Optimize User experience Increase capacity/aggregated volume TBD peak throughput Video streaming (rich media), mainly when considered single user with bad ADSL General improvement by increasing volume/aggregated traffic in multi-user environment 8
First approach Target features Provide connectivity to a CPE (Smart Balancer) by means of at least 2 channels (1 DSL+1 SAT) Provide access to the INTERNET to the CPE by means of a single Public IP Select the CPE outgoing routing of each connection between DSL or SAT on the basis of simple rules SAT failover if DSL link goes down (and vice versa) Optimize latency: ACK always via terrestrial This reduce the delay of SAT of about 50% Platform End to End architecture Standard HW for CPE and defined OS Remote control of the CPE for diagnostic and metrics KPI of the network and for the users 9
