Telecom – passive monitoring and active service solutions Speech – continuous speech recognition, voice portals, word spotting (poster) Simulation – simulation of complex systems, multiagent simulation tools Web – content & work flow management, portal development Design – innovative graphical solutions, chatbot information systems AITIA Divisions

  3. Introduction of AITIA by a ChatbotAn example of chatbot information solutions

  4. Telecommunication Division • Developing and providing software for • Network-wide Monitoring Systems • Telecommunications Traffic Analysis • Application Gateways & Service Logic • Fraud Detection Systems • Short Message (SMS) Handling • Support for Roaming Services and Testing • Location Based Services • Missed Call Notifications • EIR: Equipment Identity Register

  5. Based on in-house developed cards: 2x2 (1.5) Mbps PDH (E1/T1) 2x155 Mbps SDH/SONET and ATM 4x100 BaseT, copper 4x1000 BaseT, fiber, copper Utilizing L2 and L3 technologies: SS7 MTP HSL - many - e.g.30 links bundled MTP3b, AAL-5 Ethernet, SIGTRAN, ATM Interface cards

  6. The Present

  7. SS7 & GPRS monitoring to cover complete networks analyzes and stores traffic and call data (30 million calls/day) creates statistics and debug info real-time call tracing filtering fraudulent calls right tool for handling customer complaints Gigabit EthernetMonitoring monitoring Tbytes of data for traffic analysis to detect bottlenecks and other traffic problems on-line filtering and off-line processing software Our PassiveMonitoring Systems in Usefor 1…10 years

  8. SS7 bits SS7 bits SS7 bits statistics CDR GSM Monitoring System (SS7/PCM signaling links) Probe Probe Probe (TCP/IP) CDRs (SQL/Net) Server PMS statistics (TCP/IP) alarms (SNMP/UDP/IP) NOC

  10. T-Mobile Entire GSM and GPRS network monitored (15 million calls/day) SMS handling (Welcome, Bon voyage, Info, Mass SMS) Gateways, Roaming Testers, USSD, Fraud Detection Pannon GSM (Telenor) SMS handling (Welcome and Mass SMS) LBS – Location Based Services solution Vodafone SMS handling (Welcome and Mass SMS) Roaming Testers Invitel SS7 network monitoring and call statistics Ericsson Network Emulator for VoIP services, Semi-Transparent Relay Function NTT, Japan IP/ATM Network monitoring (1999) for the Japanese Gigabit network Some References

  11. Everyday network maintenance Traffic analysis Debugging Fraud detection Bottleneck detection Quality of Service Handling customer complaints Network optimization and planning Why to monitor?

  12. The Future

  13. To develop a multipurpose board for NGN networks as a monitoring and data-processing unitwith very high performance low power consumption high scalability composability Aims

  14. Hardware Architecture of C-Board2x10 Gbit/s --- 8…16x0.1…3.5 Gbit/s

  15. Measuring traffic mix Deep packet inspection IMS SIP platform (IP Multimedia Subsystem, Session Initiation Protocol) Routing at Layer 2, Layer 3, GMPLS (Gigabit Multiprotocol Label Switching) Video transcoding Media Gateway Firewall Traffic generator Foreseen Main Applicationsfor the C-Board

  16. AITIA and BME (Budapest University of Technology) common project + SCALOPES (Artemis) European project with 37 European partners Project leader: Pal Varga The Team
