Traceroute, TCP, and DiffServ work

Van Jacobson made vast contributions to networking, in particular related to performance. He wrote the original traceroute tool based on a idea by Steve Deering, introduced Congestion Avoidance to TCP, proposed (with Sally Floyd) Explicit Congestion Notification ECN, implemented the first zero-copy TCP in BSD Unix, and did some of the early work on what later became the Differentiated Services Architecture DiffServ and Premium IP. He is also one of the developers of BBR, a novel "model-based" congestion control algorithm.

Channel-based Networking Driver Architecture

Recent work includes a rearchitecture (based on a new "channel" concept) of the device driver and buffer management architecture that is common to networking stack implementations of practically all current operating systems. This work is described in a talk at Linux Conference Australia (LCA2006) (slides from the talk; blog article by DaveM).
