Empowering White Box SDN Solutions for ON.Labs’ CORD Applications

Presented by

Tom Anschutz (DMTS, AT&T); Saurav Das (Principal Architect, ONF); Ashok Raman (Senior PLM, Broadcom)

About this talk

In this webinar, we will discuss: • the joint effort between AT&T, Broadcom and ONF to support ON.Lab’s Central Office Re-architected as Datacenter (CORD) Project • the specific use case of a SDN based leaf-spine fabric built with bare-metal OCP hardware (using Broadcom switching silicon) and open source switch software, built on top of Broadcom provided SDN reference software, Open Flow Data Plane Abstraction (OF-DPA). The goal of the joint effort is to provide a pure SDN-based fabric implementing the following: • standard L2 switching within racks, • L3 forwarding across racks using MPLS labels between leaf and spine switches, with support for QinQ and IP multicast. • The entire fabric will be controlled by an ONOS controller cluster. Broadcom’s OF-DPA 2.0 software will be used to program the OpenFlow rules in all the white box switches
