How Pensando Redefines Networking with P4 DSC (SmartNIC) - Rolf Schaerer, Systems Engineer @ Pensando Systems
In this episode Rick and Melchior invited Rolf Schaerer from Pensando Systems and ask him all how Pensando redefines the Netwok Server Edge. "A New Way of Thinking About Next-Gen Cloud Architectures" leveraging a custom, programmable P4 processor Pensanso refers to as Capri. Capri is optimized to execute a software stack delivering cloud, compute, network, storage, and security services at cloud scale. Capri is easily installed in any standard server via the Pensando Distributed Services Card (DSC). The DSC provides software-defined services at the server edge, eliminating an assortment of discrete appliances throughout the data center and simplifying IT operations.

Service Mapping with BGP Classful Transport - Kaliraj Vairavakkalai, Principal Engineer @ Juniper Networks
In this episode Kaliraj will explain to us what BGP Classful Transport (BGP-CT) is and how it works. BGP-CT is a mechanism, referred to as "service mapping", to express association of overlay routes with underlay routes satisfying a certain SLA, using BGP.  It is a framework for classifying underlay routes into transport classes, and mapping service routes to specific transport class. The "Transport class" construct maps to a desired SLA, and can be used to realize the "Topology Slice" in 5G Network slicing architecture. BGP-CT is still work in progress in IETF. The draft can be found here: The authors welcome feedback and input for the draft.
