A Parallel Duplicate Address Detection (PDAD) mechanism to reduce handoff latency of Mobile Internet Protocol version 6 (MIPv6)

摘要: Next Generation Networks (NGN) are envisioned to be fully Internet Protocol (IP) based so that users can experience high quality and ubiquitous communication. In order realize this, Engineering Task Force (IETF) is taking advantage of Mobile version 6 (MIPv6) because it has more suitable features than MIPv4. However, MIPv6 not widely deployed due handoff latency other limitations. This causes packet loss degrades the Quality Service (QoS) for real-time applications. includes link layer establishment delay, movement address auto-configuration delay binding update/registration delay. Duplicate Address Detection (DAD) performed during which takes around 70% time total procedures. reduce this latency, a Parallel DAD (PDAD) model proposed reducing loss. The key idea behind Node (MN) solicits router advertisement (RA) in parallel its neighbor routers before leaving previous point attachment.
