![]() ![]() ![]() Cohen noted that the plan is to add support in the future for 800 Gbps over 4 data lanes at 200 Gbps per lane. The code that has been included in the Linux 6.2 kernel includes support for 800Gbps over 8 lanes at 100 Gbps/lane. ![]() Nvidia engineer Amit Cohen commented in his initial commit message to the Linux kernel that the next Nvidia Spectrum ASIC silicon is set to support 800 Gbps speed. Support was added to allow link aggregation, using the IEEE 802.3ad Ethernet standard. Multiple Nvidia engineers contributed code to the Linux 6.2 kernel to enable support for different attributes of future 800 Gbps enabled devices. Work on the 800 Gbps Ethernet standard is being done in the IEEE 802.3df task force, which published a set of baseline specifications in October.Īmong the vendors working on 800 Gbps is Nvidia, which has been active in the networking space after it acquired Mellanox for $6.9 billion in 2019. The 800 Gbps networking standard is still in its early days, but networking vendors are already rushing to make sure it is supported in Linux. The Linux 6.2 kernel also introduces a protective load-balancing feature that could potentially have a significant impact on reducing networking traffic congestion. The Linux kernel itself is a component that fits into a larger Linux operating system, with multiple vendors including IBM‘s Red Hat, SUSE, Canonical and others providing commercially supported distributions.Īmong the key networking features in Linux 6.2 is initial support for 800 Gbps wired networking as well as support for the emerging WiFi 7 wireless standard. Linux-based operating systems are commonly found inside networking equipment for both enterprise and telco use cases, as well as being widely used in the cloud. A big part of the new Linux kernel is a long list of networking-related updates that will serve as a foundation for the next generation of networking and telco equipment. On Sunday, Linus Torvalds, the creator of Linux, released the latest milestone with the Linux 6.2 kernel. At the core of every Linux-based device and operating system is the Linux kernel, which provides a foundational set of integrated capabilities.
