Google: There are three certainties in life – death, taxes and IPv6

CloudFlare Internet Summit As internet engineer jokes go, Google's Ilya Grigorik came up with a good one. On stage to answer the question "what can we expect from the internet in 2020?", he offered: As far as I can tell, by 2020, we will have flying cars, singularity... and IPv6. It's an amusing but pointed stab at the fundamental internet protocol …

Linux security backfires: Flaw lets hackers inject malware into downloads, disrupt Tor users, etc

Analysis A flaw in the Linux kernel lets hackers inject malware into downloads and webpages, smash Tor connections, launch denial-of-service attacks, and more. This is a troubling security headache because Linux is used widely across the internet, from web servers to Android smartphones, tablets and smart TVs. The TCP/IP networking …

BBC bypasses Linux kernel to make streaming videos flow

Back in September, The Register's networking desk chatted to a company called Teclo about the limitations of TCP performance in the Linux stack. That work, described here, included moving TCP/IP processing off to user-space to avoid the complex processing that the kernel has accumulated over the years. It's no surprise, then …

Google 'cubists' fix bug in Linux network congestion control, boost performance

A bit of “quality, non-glamorous engineering” could give a bunch of Linux servers a boost by addressing an unnoticed bug in a congestion control algorithm. This little code snippet addresses the ten-year-old slip-up in the open-source kernel's net/ipv4/tcp_cubic.c code: static void bictcp_cwnd_event(struct sock *sk, enum …

TCP is a wire-centric protocol being forced to cut the cord, painfully

The venerable Transmission Control Protocol (TCP) is one of the foundation protocols of the Internet, but it's not so hot at mobile environments, says Juho Snellman of Swiss telco software concern Teclo. The Register took an interest in Teclo's work after spotting this presentation to a SIGCOMM workshop. In an interview with …

Staunch your Heartbleed patching: FreeBSD has a nasty credentials leak

Got FreeBSD? Get busy on the patch, because a problem with its TCP ordering has emerged, with both denial-of-service and data leakage as possible effects. The issue exists in how the popular Unix-like operating system handles TCP packets received out-of-order. Packets are held in a reassembly queue until they can be re-ordered …

MIT boffins give computers control to clock faster TCP

A group of MIT researchers has unveiled a machine learning approach to TCP congestion which could form the foundation of the next round of improvements to the venerable protocol's performance. Dubbed “Remy”, their TCP control software is based on the idea that even sophisticated modern congestion control algorithms (like …

Fujitsu reveals data transfer protocol 30 times faster than TCP

Fujitsu has taken the wraps of a new data transfer protocol which it claims is 30 times faster than TCP and will help speed up mobile web browsing and file downloads and reduce virtual desktop latency. The new proprietary tech is based on the user datagram protocol (UDP) employed for streaming media. As such, it can …

The software used to be called Voltaire Messaging Accelerator and came to Mellanox through its November 2010 acquisition of networking …

NASA space tests 'interplanetary internet' protocol

NASA has announced successful space tests of its new purpose-designed interplanetary communications networking protocol, which it calls Disruption-Tolerant Networking (DTN). Famed TCP/IP pioneer Vint Cerf was instrumental in the space net's design. "This is the first step in creating a totally new space communications …
