Host based networking (HBN) is a DOCA Service that runs on NVIDIA's DPU. It orchestrates network connectivity of dynamically created VMs/Containers on cloud servers. HBN service is a BGP router that supports EVPN extension to enable multi-tenant cloud.
Introduction
The host-based networking (HBN) solution packages a set of network functions inside a container which, itself, is packaged as a service pod to be run on the DPU.
At the core of HBN is the Linux networking DPU acceleration driver. Netlink to DOCA daemon, or nl2docad, implements the DPU acceleration driver. nl2docad seamlessly accelerates Linux networking using DPU hardware programming APIs.
The driver mirrors the Linux kernel routing and bridging tables into the DPU hardware by discovering the configured Linux networking objects using the Linux Netlink API. Dynamic network flows, as learned by the Linux kernel networking stack, are also programmed by the driver into DPU hardware by listening to Linux kernel networking events.
