Starting w/ IP Heterogeneous reality: regional solutions SLA: WAN provider’s contracts with suitable QoS targets are expensive and difficult to be met in national scale ATN-Br Guidelines • Support Legacy and new ATM Applications • Support for heterogeneous WAN Network solutions with Integrated management • Common IP based network (mid term) • Technical Management Center support • ATC Contingency Control Centers support • Complex project / External consultancy (R&D - CPqD & University – CETUC/PUC-Rio) ATN-Br: Main Planning Factors • ATN Router: Multifunctional Integrated Equipment – – – – – – Protocol conversion Interface conversion Mux/Demux WAN routing (E1/MPLS/SATCOM) Delay compensation and jitter management Network management and control facilities • EUROCAE WG-67 Standards • Support ATM assets and WAN transitions ATN-Br Trial Main Objectives • Validate a technical solution model over a reduced configuration/arquitecture. • Verify climax operation over IP/MPLS WAN • Protect investment by interfacing with legacy equipment • Evaluate: – capacity and efficiency of the MFI to manage 3 different WAN technologies (E1Terrestrial, Satcom and MPLS/IP) – capacity of Brazilian WAN providers on the network requirements – efficiency of priority-based traffic routing to implement a bandwidth flexible without safety compromise • Learn lessons to progress on the national ATN planning and implementation ATN-Br Trial Configuration • Subset of ATS facilities – CINDACTA II (ACC) – DTCEA Florianópolis (APP) – DTCEA Morro da Igreja (remote site) • Subset of ATM services – Voice for air-ground communication (with climax/off-set-carrier) – Radar – PABX – Data (intranet) CINDACTA II MFI MFI DTCEA-MDI • Heterogeneous WAN management – MPLS – E1 – SATCOM IP MFI DTCEA-FL E1 IP SATCOM ATN-Br Trial Architecture MFI V.35 V.35 NODE 1 CINDACTA II TDM E1 TDM E1 ETH IP MFI NODE 2 DTCEA-FL ETH IP ETH IP V.35 TDM E1 MFI NODE 3 DTCEA-MIDI ATN-Br Trial interfaces Network Connectivity IP via MPLS E1 digital Node MFI Applications V.35 Satellite Trial Validation Tests • FAT and SAT (MFI) • Network SAT (*) – E1 – Satcom data link – MPLS • Integration Test (*) with Legacy • Systemic Test (*) – WAN Networks Auto-routing – Performance over any WAN Networks (emphasis in MPLS Network) – Flight test (climax) (*) Tests performed with support of Fundação CPqD, an independent Brazilian telecom R&D organization (http://www.cpqd.com.br) Validations and Tools • WAN Network Tests: To assure the network provides the desired performance in terms of QoS – Throughput – Latency, Jitter, Packet Loss – Traffic prioritization • Integration and Systemic Tests: To assure the subsystems when integrated provide the desired performance as a unit – – – – QoS, Voice Quality Bandwidth allocation, Services prioritization Triple way routing Dynamic delay compensation • Tools: IxChariot, Abacus, Wireshark, Cascade Pilot, NetPerSec Routing Performance Test • Routing performance tests based on VHF Radio Connections – Successful tests of all automatic failover and re-routing options MFI Initial scenario Radio connection between Cindacta II and Florianópolis MFI MFI Goal of the test case •Verify automatic re-establishment of connection on network outage •Verify all routing options (E1, VSAT & IP) •Verify multihop routing Climax Radio Operation Test Speech quality verification over IP/MPLS, E1/TDM and V.35/SATCOM – Climax operational verification performed using test flight (GEIV) – Verify in practice the delay compensation (over single and multiple WAN) – Communications were operated from ACC CINDACTA II in Curitiba using 135.85 MHz Communications with the aeroplane were kept at any time during the flight over a total distance of 1248 NM Main Results • Interoperability with legacy equipment • Safe routing and priority based traffic handling over different networks • Successful failover/routing tests over heterogeneous WAN • Radio climax operation over different WAN, including VoIP over IP/MPLS WAN Next Steps • • • • Trial 2nd Phase: Complete digital integration. Develop a transition plan (safe and practical) Implement ATN-Br segment in one FIR National level implementation Conclusions The Trial Project has demonstrated the possibility to progress in the ATN-Br planning and implementation in a larger scale.
