Research

Currently, I am working on implementing NR-SACKs in FreeBSD operating system and  designing experiments to investigate how SCTP with NR-SACKs perform with respect to SCTP with SACKs. NR-SACKs is an extension to SCTP acknowledgment mechanism proposed by our  Protocol Engineering Lab. Please refer to the publications/presentations below for more information about NR-SACKs. For more information about research at Protocol Engineering Lab please visit the PEL Web Site.

Presentations

Here is a set of Power Point slides discussing the details of NR-SACKs.

Here is the same set of slides in pdf format which, of course, cannot play the animations.
