  1. Military University of Technology Faculty of Electronic Institute of Telecommunication AN ADAPTATION GENERATED PACKET STREAM IN SECURE NARROWBAND NETWORK IPV6 Urszula Ostrowska Tutor: Marek Amanowicz, Prof.

  2. Presentation scheme VoIPv6 application Requirements for IPSec procedure Procedure: header compression IPSec/IPv6, packet multiplexation RT i NRT Test bed configuration Research results Summary Future tasks An adaptation generated packet stream in secure narrowband IPv6 network

  3. Codecs in VoIPv6 application Codec MELP 1200 bps – packet length 95 B 200 ms Codec MELP 2400 bps – packet length 119 B 143 ms Codec CELP 4800 bps – packet length 101 B 62.5 ms An adaptation generated packet stream in secure narrowband IPv6 network

  4. VoIPv6 application Codec change: for value b < 5.8 kbps - MELP 1200 bps for value 5.8 kbps < b < 11.2kbps - MELP 2400 bps for value b > 11.2 kbps - CELP 4800 bps An adaptation generated packet stream in secure narrowband IPv6 network

  5. Expectations for header compression and security mechanism • Reduce large information redundancy in IPv6 and IPSec protocols • Improve efficiency assurance used channel capacity in mobile network for real time stream (RT) and data (NRT) • Provide security information assurance An adaptation generated packet stream in secure narrowband IPv6 network

  6. Perform RT service in IPv6 narrowband network Classification and prioritization of RT and NRT packets RT and NRT stream multiplexing mechanism RT packet header compression NRT packet and control packet segmentation Use standard IPSec mechanism Requirements for IPSec procedure An adaptation generated packet stream in secure narrowband IPv6 network
