Protocol-Independent FIB Architecture, with Ryo Nakamura from University of Tokyo - a podcast by Ben Pfaff

Ryo Nakamurais a PhD
student at The University of Tokyo, studying IP networking, overlaynetworking, and network operation. This episode is a recording I made of
his talk duringAPSys 2016, the
Asia-Pacific Workshop on Systems, on Aug. 5, based onProtocol-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 centernetworks, network overlay built upon tunneling protocols becomes an
essential technology for virtualized environments. However, the tunnelingstacks network layers twice in the host OS, so that processing to
transmit packets increases and throughput will degrade. First, this papershows the measurement result of the degradation on a Linux kernel, in
which throughputs in 5 tunneling protocols degrade by over 30%. Then, wedescribe the proposed architecture that enables the shortcut for the
second protocol processing for network overlays. In the evaluation with adummy interface and a modified Intel 10-Gbps NIC driver, transmitting
throughput is improved in 5 tunneling protocols and the throughput of theLinux kernel is approximately doubled in particular protocols.

Before the talk, session chairFlorin Dinuintroduces the
speaker. Following the talk, the questions come fromBen Pfaff,Sorav Bansal, and
Florin, respectively. Sorav's question refers to my own talk fromearlier the same day at the conference, which is published asOVS Orbit Episode 14.
