Ryo Nakamura is a PhD student at The University of Tokyo, studying IP networking, overlay networking, and network operation. This episode is a recording I made of his talk during APSys 2016, the Asia-Pacific Workshop on Systems, on Aug. 5, based on Protocol-Independent FIB Architecture for Network Overlays, written with co-authors Yohei Kuga (from Keio University), Yuji Sekiya, and Hiroshi Esaki.

The abstract for this paper says:

We introduce a new forwarding information base architecture into the stacked layering model for network overlays. In recent data center networks, network overlay built upon tunneling protocols becomes an essential technology for virtualized environments. However, the tunneling stacks network layers twice in the host OS, so that processing to transmit packets increases and throughput will degrade. First, this paper shows the measurement result of the degradation on a Linux kernel, in which throughputs in 5 tunneling protocols degrade by over 30%. Then, we describe the proposed architecture that enables the shortcut for the second protocol processing for network overlays. In the evaluation with a dummy interface and a modified Intel 10-Gbps NIC driver, transmitting throughput is improved in 5 tunneling protocols and the throughput of the Linux kernel is approximately doubled in particular protocols.

Before the talk, session chair Florin Dinu introduces the speaker. Following the talk, the questions come from Ben Pfaff, Sorav Bansal, and Florin, respectively. Sorav's question refers to my own talk from earlier the same day at the conference, which is published as OVS Orbit Episode 14.
