  • SD-Fabric


SD-Fabric is a complete P4 programmable networking fabric. The stack enables programmers to execute custom forwarding logic in performant networking hardware, making it possible to implement features that would otherwise consume expensive compute resources.

SD-Fabric creates an Ethernet fabric optimized for edge application out of a collection of switches. SD-Fabric uses SDN control to convert a spine-leaf assembly of switches into what appears to be a single routing instance to all hosts and routers connected to the fabric.  SD-Fabric also enables fine-grained measurement through the use of INT services, and is iteratively integrating network verification and closed-loop control capabilities coming from project Pronto research.
