- Newly added support for Mellanox’s Spectrum-2 chipset for faster performance, Broadcom’s Qumran chipset for deep buffering at the top of rack coming soon, Facebook’s Minipack-- an open, modular chassis with a single 12.8TB chip, and additional campus networking platforms from Dell EMC.
- Migration to the latest, and most advanced, Linux kernel for greater route scale, the latest security updates, and thousands of contributions from the broader Linux community.
- Support for SwitchDev, an open source in-kernel abstraction model, providing a standardized way to program switch ASICs and speed development time.
- Enhancements to our EVPN implementation (EVPN-PIM and EVPN multi-homing) for Layer 2/Layer3 connectivity, making it the simplest, most scalable, and easiest to configure EVPN solution.
- Comprehensive end-to-end automation for Continuous Integration/Continuous Delivery (CI/CD) workflows including simulation, validation, troubleshooting and NetDevOps practices such as Infrastructure-as-Code (IaC).
- The ability to build a single fabric across data center and campus environments enabling a common operational model.
