ARM And Nokia Want To Update The TCP/IP Stack
Comments Off on ARM And Nokia Want To Update The TCP/IP Stack
Nokia and ARM want to spruce up the TCP/IP stack to make it better suited to networks that need to operate at high speed and/or low latency.
Legacy TCP/IP is seen as one of the slowing points for a lot of future IT – particularly 5G. LTE was IP-based but it was hell on toast getting it to go and as networks get faster and more virtualised, the TCP/IP stack is failing to keep up.
At the moment Nokia and ARM are using 5G to drive other companies into looking at a
fully revamped TCP/IP stack, optimized for the massively varied use cases of the next mobile generation, for cloud services, and for virtualization and software-defined networking (SDN).
Dubbed the OpenFastPath (OFP) Foundation, founded by Nokia Networks, ARM and industrial IT services player Enea. The cunning plan is to create an open source TCP/IP stack which can accelerate the move towards SDN in carrier and enterprise networks.
AMD, Cavium, Freescale, HPE and the ARM-associated open source initiative, Linaro are all on board with it.
The cunning plan is to create open but secure network applications, which harness IP packet processing. Some want very high throughput, others ultra-low latency others want both and it is probably going to require a flexible standard to make it all go
The standard would support faster packet forwarding, via low IP latency combined with high capacity, and so reduce deployment and management costs by making networks more efficient.
This appears to be based around getting TCP/IP out of the kernel and using them for packet processing involves a number of operations (moving packets into memory, then to the kernel, then back out to the interface) which could be streamlined to reduce latency.

Bonets Attack U.S. Banks

Evidence collected from a website that was recently used to flood U.S. banks with junk traffic suggests that the responsible parties behind the ongoing DDoS attack campaign against U.S. financial institutions — thought by some to be the work of Iran — are using botnets for hire.
The compromised website contained a PHP-based backdoor script that was regularly instructed to send numerous HTTP and UDP (User Datagram Protocol) requests to the websites of several U.S. banks, including PNC Bank, HSBC and Fifth Third Bank, Ronen Atias, a security analyst at Web security services provider Incapsula, said Tuesday in a blog post.
Atias described the compromised site as a “small and seemingly harmless general interest UK website” that recently signed up for Incapsula’s services.
An analysis of the site and the server logs revealed that attackers were instructing the rogue script to send junk traffic to U.S. banking sites for limited periods of time varying between seven minutes and one hour. The commands were being renewed as soon as the banking sites showed signs of recovery, Atias said.
During breaks from attacking financial websites the backdoor script was being instructed to attack unrelated commercial and e-commerce sites. “This all led us to believe that we were monitoring the activities of a Botnet for hire,” Atias said.
“The use of a Web Site as a Botnet zombie for hire did not surprise us,” the security analyst wrote. “After all, this is just a part of a growing trend we’re seeing in our DDoS prevention work.”
