In this talk Markuze Alex et al describe how they improved, by orders of magnitude, client download times of a global overlay network across public clouds. The overlay network known as the Pathway project (operated by VMware Research) interconnects geographical spread of public clouds and their vast compute and networking infrastructure

The secret sauce? KTCP, a Kernel module running on a modified Linux Kernel which implements novel TCP splicing.

Markuze and co. will discuss why their approach is different relative to the many approaches already out in the wild that implement TCP proxying. They will present numbers against classical approaches which demonstrate that KTCP is able to considerably increase the link utilization by TCP connections and reduce the connection latency close to its theoretical minimum.
