This talk will focus on various highlights of ethernet drivers and their maintenance as the speaker was able to practice for several years to the Linux...
Berkeley Packet Filter is an old friend for most people that deal with network under Linux. But its extended version eBPF is completely redefining the scope of usage and interaction with the kernel. It can indeed be used to instrument most parts of the kernel. This...
Efficient monitoring of large-scale networks poses a delicate balance between capture granularity on the one hand and the imposed overheads and performance penalties on the other. Skydive is an open source real-time network topology and protocol analyzer, featuring...
This talk will introduce XDP (eXpress Data Path), and explain how this is essentially a new (programmable) network layer in-front of the existing network stack. Then it will dive into the details of the new XDP redirect feature, which goes beyond forwarding packets...
XDP (eXpress Data Path) is the new programmable in-kernel fast-path, which is placed as a layer before the existing Linux kernel network stack (netstack). We claim XDP is not kernel-bypass, as it is a layer before and it can easily fall-through to netstack. Reality is...
