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, implemented the first zero-copy TCP in BSD Unix, and did some of the early work on what later became the Differentiated Services Architecture and Premium IP.

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).
