Network Service Mesh: An Introduction - Ed Warnicke, Cisco Systems & Frederick Kautz, Doc.ai
Network Service Mesh (NSM) is a novel approach solving L2/L3 network use cases in Kubernetes that are tricky to address with the existing Kubernetes Network Model. Inspired by Istio, Network Service Mesh maps the concept of a service mesh to L2/L3 payloads.

Network Service Mesh Use Cases such as:

* Connecting Pods to:
-VPN Gateways
-Non-Kubernetes virtual bridge domains
-The *right* physical NIC or SR-IOV VF for their needs
-Multiple-interfaces
* Cloud-native NFV use cases

Network Service Mesh controls the L2/L3 data planes to deliver these types of use cases. Network Service Mesh enables users to express the context of their network needs in a Cloud Native manner, rather than manually stringing together disjoint interfaces, IPAM, and subnets.

Finally, we discuss how audience members can get involved and help drive the direction and development of NSM.

Packet Walk(s) in Kubernetes - Don Jayakody, Big Switch
Have you ever wondered how the packets are getting forwarded inside Kubernetes with different CNI plugins? Whether it’s getting encapsulated? How are ARPs getting resolved? How the packets flow outside from your K8S cluster etc.

When it comes to networking inside Kubernetes, selecting the correct networking solution may be one of the most important decisions you may face when trying to run a Kubernetes cluster in production. Therefore it's beneficial to have a good understanding of different options out there and most importantly how these networking options are different from each other.

In this presentation, I’ll go over packet by packet level details of how the network plumbing is happening with different CNI plugins including, Flannel, Calico & Cilium. I'll cover different packet flows and try to draw different examples so that we all can understand where it's different.

Cloud Native Network Tracing in an Istio Service Mesh Using OPNFV Clover's Clovisor - Stephen Wong, FutureWei Technologies, Inc.
Clovisor, from OPNFV Clover project, is a cloud independent and CNI-plugin agnostic network tracing module. It augments tracing data from Istio service mesh via providing raw network traces on a per session/transaction basis, and implementing a golang plugin infra to support multiple network protocols.

Clovisor integrates tightly with Kubernetes and Istio, and utilizes IOVisor/goBPF to tap into node and k8s pod interfaces to trace packets, which minimizes impact on kernel packet forwarding. It uses OpenTracing APIs to send to Jaeger tracer its network traces, and features a sample analytic engine to correlate traces from Istio and Clovisor. These resulting consolidated traces are particularly useful for deployments in:
o Hybrid cloud
o Edge computing
o Multi-site deployment

This presentation will give detail introduction to Clovisor, its architecture and design, and will provide a demo

Panel Discussion: Towards Kubernetes as the Network Service Orchestrator - Heather Kirksey, The Linux Foundation; Ramki Krishnan, VMware; Ed Warnicke, Cisco Systems; Jeffrey Saelens, Charter Communications; and Nikolay Nikolaev, VMware
In the current landscape, network services are defined by a slow-moving standards ecosystem (TOSCA etc.) with vendor proprietary extensions. With the advent of Edge Computing and 5G, dynamism of Network Services is a critical element in achieving end-to-end service agility for applications and networks for enterprises, network operators and beyond. While transition from PNFs->VNFs->CNFs is an important element of this transformation, delivering a dynamic network service using an industry standard API is a key gap to address in a disaggregated landscape.

This panel discusses how the open source effort Network Service Mesh (NSM) uses the extensibility of Kubernetes API to deliver dynamic network services across Distributed DC deployments by seamlessly interconnecting PNFs, VNFs and CNFs at Layer 2/3. This panel also elaborates on the current state of NSM and future architectural plans.

Identity-based Cross-cluster Fabrics - Challenges & Rewards - Igor Tarasenko, Bayware
Cloud-native infrastructures and platforms have radically improved application deployment with one major change still to come - replacing IP addresses with Identity - as defined by applications - for cross-cluster service-to-service communication.
Challenges include deriving application intent and identity directly from the application manifest, enabling cross-domain networking based only on identity, making flows directly programmable as code, and achieving authorization and authentication of identity as well as flow telemetry and code updates that are virtually instant. Rewards include making NetOps a reality, ie bringing network policy as code into CI/CD pipelines, creating networks that dynamically respond to applications and conditions, giving applications full observability to flow-level telemetry. Also, this enables compute-in-network functions for advanced AI and IOT applications.

Lightning Talk: Secondary Network Interfaces for Containers, Its Types and Use-cases - Tomofumi Hayashi, Red Hat
The last year, 2018, Kubernetes Network Plumbing Group (NPWG) successfully published the first de-facto standard document for network attachments, with reference CNI plugin, Multus-CNI. It makes us to having two or more interface to the pods/containers in Kubernetes. But it is not the goal, just a start of the journey of advanced container networking. "Which interface is good for secondary network?", that is the first step. This talk will survey over several CNI interface plugin and CNI IPAM plugin, like ipvlan, macvlan, DHCP and static and will show best practices for several use-cases.

Using Kubernetes to Build a Microservices Cloud Native Network OS to Bring CI/CD to Networking - Glenn Sullivan, SnapRoute
The adoption of CI/CD by DevOps-minded organizations has led to more flexible, secure and agile infrastructure with new features and functionality being constantly deployed and improved upon. With these architectures in place, the compute and storage pieces of the environment have benefited from the rapid deployment and constant improvement that CI/CD mandates. Built upon legacy, monolithic architectures — most Network Operating Systems (NOS), are not able to take advantage of CI/CD philosophies. What we built with Kubernetes is a new NOS architecture that is built upon core cloud-native principles of microservices and containerization to enable CI/CD for networking.

This talk gives an overview of adopting Cloud Native principles to bring CI/CD principles to your network. Session attendees will get key take-aways and practical advice on how to implement DevOps in their network.

Accelerated Container Networking using DPDK - Sujata Tibrewala & Muthurajan Jayakumar, Intel Corporation
DPDK leverages the underlying modern hardware architecture to optimize packet processing on Software. Kubernetes as an orchestration system for containers focuses on service velocity, simplicity and scalability. One aspect of that simplicity, container networking by default has only one network interface. However one networking interface is not enough to implement network functions in containers. With the demand of 5G and edge it is becoming more and more critical to implement Container Network Functions. DPDK plug-ins are vital in filling this gap in containers using Conatiner Network Interface, CNI. In this presentation, we will learn how the DPDK plug-ins help in features like Node Feature Discovery, Support for CPU core pinning for K8 pods, Support for Service Chaining aka East West traffic , SR-IOV and control of VNF level – with 100s or 1000s of VNFs.

Next-Generation NFV Orchestration - Tal Liron, Red Hat
Kubernetes has optimized our ability to deliver applications to the cloud. But what about network service workloads? Efforts to create next-gen "CNFs" notwithstanding, it's possible to support the existing "V" in NFV on Kubernetes right now using technologies like KubeVirt. But is that all we need? ONAP already has some support for deploying VNFs on Kubernetes, but in this presentation we'll look at how Kubernetes itself can take over most of our orchestration tasks.

We'll do this by a gap analysis: What components do we need to add to Kubernetes in order turn into a virtual network service cloud? We'll see that we're much closer to achieving this goal than you might think.
