Andreas Petlund received the Ph.D. degree from the University of Oslo, Norway, in 2009. His Ph.D. thesis focused on low-latency transport for interactive and time-dependant applications. He is currently a Research Scientist at Simula Research Laboratory, Fornebu, Norway. He is currently coordinating the “Reducing Internet Transport Latency” (RITE) FP7 EU project and leading a national project on low latency for thin-stream applications. His work on retransmission mechanisms to reduce latency has resulted in a suite of mechanisms, several of which are available in the Linux kernel. The main topic of his current work is systems and network optimizations for time-dependant applications, but he also has experience in kernel-level optimizations, embedded systems, and heterogeneous processor systems.
