VPP Host Stack - Florin Coras, Cisco
Although packet forwarding with VPP and DPDK can now scale to tens of millions of packets per second per core, lack of alternatives to kernel-based sockets means that containers and host applications cannot take full advantage of this speed. To fill this gap, VPP was recently added functionality specifically designed to allow containerized or host applications to communicate via shared-memory if co-located, or via a high-performance host stack inter-host.

In this talk, we will provide a short overview of the major components of the host stack: shared memory fifos, session layer, TCP stack, communications library (VCL) and discuss how existing and new applications could leverage the benefits of this new architecture.

Accelerating TLS for Cloud Native, with FD.io VPP and QAT - Ping, Intel
TLS is fast becoming a critical workload in Cloud Native. How do we offload cryptography to hardware without any change in application are now critical industry questions?

This presentation will show a "transparent" and "asynchronous" high-performance solution that addresses the above issues.

"Transparent": Extending cloud native apps to integrate with FD.io VPP accelerated TCP stack in userspace. The TLS layer in VPP is viewed as just one of a number of transport layers to the supporting application, providing applications the ability to integrate with the TLS layer transparently.

"Asynchronous": Extend existing OpenSSL "file descriptor" asynchronous mechanism to an efficient and generic new interface, thus TLS host stack flow in VPP and the hardware cryptography flow can be pipeline simultaneously without user/kernel space switch which maximizes both the CPU and hardware utilization.

Accelerating SPDK Storage Networking with VPP TCP - Tomek Zawadzki, Intel
The Storage Performance Development Kit (SPDK) is an open-source software project for accelerating storage and storage networking applications with a set of userspace, polled mode drivers and libraries.  SPDK provides libraries for TCP-based block storage protocols such as iSCSI and NVMe/TCP.  But while SPDK provides userspace polled mode drivers for NVMe SSDs, it still relies on the Linux kernel TCP stack for TCP, IP and Ethernet processing.  Profiling shows that up to 75% of CPU cycles in these applications are spent just on the kernel network processing.

This talk will discuss the work that SPDK has been doing in collaboration with FD.io on using VPP for userspace TCP-based storage networking use cases.  A description of SPDK's architecture and how VPP fits in will be provided, as well as performance and efficiency data that has been collected over the last several months.

CNFs in Switzerland: Reproducible Performance Testing in a Neutral Environment - Taylor Carpenter, Vulk Coop
Tired of zero-touch claims that never live up to the hype? We were as well, so we created clean room implementations to compare the performance of Cloud-Native Network Functions (CNF) to Virtual Network Functions (VNF). We also created fully reproducible, real-world reference use cases that chain 100% open source, Network Functions. In this talk, we will share the CNF vs VNF comparison results and highlight how a neutral test environment can increase collaboration between groups and allow third parties to validate claims in their own environments.

High Performance Cloud Native Networking: K8s unleashing FD.io - Maciek Konstantynowicz, Cisco
The high-performance software data plane provided by FD.io VPP makes application and host networking fast and very efficient. Kubernetes makes container workloads easy to manage, operate and network, all at massive scale. It is rational to integrate the two, to see how the best of both worlds perform together and how they can drive high-performance communication in scaled-out and scaled-up cloud-native micro-services deployments.

This talk will detail how FD.io VPP is on a path to realize the vision of terabit networking on COTS servers, and how it integrates into the K8s (eco-)system through the Ligato, Network Service Mesh, and Contiv-VPP open-source projects. It will refer to open-source benchmarking data for checks against reality and against the laws of physics.

A VPP-based Implementation of Kubernetes Services and Policies - Nikos Bregiannis, Cisco
Kubernetes network policies specify how groups of pods are allowed to communicate with each other and other network endpoints. For a packet forwarding engine, such as VPP, this is an abstract definition for access control between endpoints. This presentation will introduce a pure userspace implementation of kubernetes policies in VPP showing high performance and adding the flexibility of different data plane rendering. Service is a Kubernetes abstraction providing an entry point of access to a group of pods. In a Contiv/VPP,  load-balancing and translations between services and endpoints are done inside VPP using the high-performance VPP-NAT plugin. VPP-NAT plugin is an implementation of NAT44 and NAT64 for VPP. This presentation will introduce a Service Proxy implementation in VPP that enables high-performance load-balancing, forwarding and dynamic source-NAT node-outbound IPv4 traffic.

Facts on the Ground Stitching up an L2 CNF with Network Service Mesh and VPP - Thomas Herbert, Red Hat
In this talk, Thomas will discuss the implementation of  an L2 forwarder using Network Service Mesh and VPP. By way of a practical example, this talk will show how NSM can serve as a vehicle for constructing a layer 2 network using a VPP based forwarder. Attendees will see the gRPC protocol additions for injecting an L2 service into a Kubernetes pod. They will also see how a container with VPP forwarder can be injected into the pod to handle L2 traffic. Also, he will discuss how this can be extended for other network elements such as L3 routers, tunnel endpoints or layered network slices using SRV6 or MPLS.

High Performance, Inexpensive NGFW? You Must Be Kidding. - Jim Thompson, Netgate, Inc.
The NGFW market will grow to $4.3B by 2022. Drivers? Cloud appliances, SME adoption, and IoT / BYOD device explosion. A gravy train for NGFW vendors with specialty silicon, monolithic software, and “don’t try this alone” support subscriptions. Translation? Expensive.

Is there an alternative? Yes. It’s called an open-source NGFW. Huh? All of those complex DPI, IDS/IPS, app control, packet filtering, email security, threat protection / sandboxing, and traditional firewall features? And at 1, 10, or 100 Gbps speeds?

It’s closer than you think.  See how these requirements can be met with open source software that leverages FD.io’s data IO performance, scalability, efficiency, and programmable flexibility for networking and security across bare metal, VM, and container deployments. And, best of all, prepare to have a “pennies on the dollar” discussion with your CFO.

Accelerating Network Security with VPP and Network Service Mesh - Matt Ellison, Arroyo Networks
Arroyo is building fast and scalable cloud-based network security, providing enterprise network operators the ability to adapt to the changing threat landscape by replacing traditional networking appliances and functions.

While containers have made it easy to scale computing horizontally, network function technologies have lagged behind. Traditional NFV does not adapt and scale as the industry continues to trend towards cluster-based workloads.

At Arroyo, we have made strides towards providing truly scalable Cloud-Native Network Functions backed by Kubernetes, with the help of: 
1. VPP to deliver packets to our CNFs and build customized networking solutions for our customers. 2. Network Service Mesh for orchestration and scaling to leverage the power of Kubernetes clustering to power our CNF platform.
3. Bringing it all together with Arroyo’s Parallel Packet Processing Pipeline model.
