Google chops latency of its Andromeda SDN stack by 40%

Google released a new edition of its Andromeda SDN stack that reduces network latency between Compute Engine VMs by 40% over the previous version.

Andromeda 2.1, which underpins all of Google Cloud Platform (GCP), introduces a hypervisor bypass that builds on virtio, the Linux paravirtualization standard for device drivers. This enables the Compute Engine guest VM and the Andromeda software switch to communicate directly via shared memory network queues, bypassing the hypervisor completely for performance-sensitive per-packet operations.

Google noted that is has cut the latency of its SDN stack by nearly a factor of 8 since it first launched Andromeda in 2014.

TRON Forum transfers IoT OS to IEEE

The TRON Forum, which supports a development project called TRON Project that addresses real-time architecture for embedded systems, will transfer ownership of the TRON µT-Kernel 2.0 to the IEEE Standards Association (IEEE-SA). This effectively transfers a leading real-time operating system (OS) title for 16- and 32-bit microprocessors deployed throughout the IoT ecosystem to IEEE.

The arrangement also provides a license to TRON Forum for use of the intellectual property.

“In our ongoing efforts to foster openness and the broad utilization of globally-recognized technical standards, the IEEE-SA continues to seek collaborative agreements that help advance technology for humanity,” said Konstantinos Karachalios, managing director for the IEEE-SA. “This agreement with the TRON Forum will pave the way for development of new standards in line with the goal of both our organizations to promote open innovation frameworks. We look forward to our continued work and cooperation.”

The TRON Project is a project launched in 1984 by Prof. Ken Sakamura, now dean of the Faculty of Information Networking for Innovation and Design (INIAD) at Toyo University. The Project aims to build an open architecture for embedded systems.
