HIP-enabled networking vs. traditional IP networking : a performance analysis using Tempered Airwall

Sammanfattning

This thesis presents a comparative analysis of HIP-enabled networking and traditional IP networking, focusing on their performance by conducting experiments with Tempered Airwall. Our study highlights how HIP's introduction of public-key cryptography adds overhead to data packets, which decreases network speed but does not have a significant impact on standard internet usage, such as web surfing and communication. However, the performance impact becomes more pronounced during high-demand applications like 1080p video streaming or large file downloads, where the overhead causes noticeable buffering and longer download times. Notably, HIP's resilience during network transitions, such as WiFi switching, demonstrates improved mobility handling compared to traditional IP networking. Instead of the connection being aborted such as in IP networking, HIP maintains the connection, thereby preventing abrupt disruptions. This improved mobility is attributed to HIP’s ability to retain the same overlay IP address during connectivity transitions. This research contributes to understanding HIP’s benefits and limitations, suggesting its suitability for environments where network stability during mobility is critical, while also highlighting potential drawbacks in high bandwidth scenarios.
