All Optical Access Platforms for Fiber to the Home Networks Francesco Matera, Alessandro Valenti, Edion Tego, In cooperation with Istituto Superiore delle Comunicazioni e delle Tecnologie dell’informazione (ISCOM) FIAT LUX Conference Rome, June

2/18 Strategies for IP over Optics  APPs versus Physical Layers (does APPs exploit all the fiber bandwidth?)  Introduction of Measurement Plane (FP7 EU MPLANE project) Optical network experimental infrastructure Different platform for Digital Television on the same fibre infrastructure (experimental investigation)  TV over IP (unicast, multicast); DVB-T over fiber (broadcast) MPLANE: QoE vs QoS: Tests on bandwidth exploitation (TCP vs UDP) Outline 2 FIAT LUX Conference Rome, June

Data Center

4/18 4 Network Business Models For current networks too low revenues for network operators To assure QoS: Class of Services based on logical and physical paths  Optical wavelengths (L1); LSP (MPLS, VPLS, Carrier Ethernet) (L2.5) Software Defining Network and Network Function Virtualization New IP strategies: Content Centric Networks (CCN) (or Information- Centric Networks)  from host to content oriented: user looks for contents, not for host! New role for routers: forwarding based on "name" and cash FIAT LUX Conference Rome, June

13/18 Use Cases 1. SLA Certification and Verification (FUB) 2. DaaS Troubleshooting (NEC) 3. Content and Service Popularity (NEC, ALBLF, Polito) 4. ISP/CDN Cooperation (ALBLF, FTW, Polito) 5. Streaming Delivery Active Measurements (Netvisor, TI, Fastweb) 6. WEB Browsing QoE (EURECOM, TI, Fastweb) 7. Mobile Network Performance (TID, FTW) 8. Large-Scale Network Anomaly Detection (Polito, FTW)

14/18 mSLAcert active probe A novel active probe has been introducted to verify and certify the bandwidth offerted to the users by the ISP It is based on UDP tests that measures bandwidth at layer 2 TCP tests are also included to measure throughput (layer 4)

15/18 mSLAcert status Capabilities 1. Ping – Dettail 2. Ping – Average 3. TCP throughput – Dettail 4. TCP throughput – Average 5. UDP throughput – Dettail 6. UDP throughput – Average 7. MSLA – Dettail 8. MSLA – Average

18/18 Bandwidth exploitation in GPON: TCP vs UDP (FP7 MPLANE) 18 TCP RTT=0 RTT=100 ms UDP RTT=100 ms 100 Mb/s decreases down to 40 Mb/s with TCP No reduction with UDP FIAT LUX Conference Rome, June

19/18 19 GPON 100 Mb/s Multisection (RTT=100 ms) FIAT LUX Conference Rome, June

20/18 Further investigations SLA (layer 4 vs layer2) could be achieved with Multissession TCP tests (M>10) (IET Communication….); It is under study for Misurainternet. Analysis of the only normative for QoS (ETSI):  TCP test in 10 ms  We demonstrate that it is wrong at 100 Mb/s
