Tuesday, October 16, 10:20-11:10 a.m.

Next Generation R&E Ecosystem: Plans for Next Evolution of Internet2 Infrastructure

Internet2 staff and advisory groups have been working throughout the summer and fall to advance the detailed planning for Internet2’s next set of infrastructure technology investments to begin in 2019. During this session, we will begin to provide the outlines of the technical and service planning activities for the new Internet2 network and link our own work to presentations throughout Tech Exchange that have been piloting and researching technologies and service models.

We plan to share specific updates on the optical platform, testbed activities, routing and switching topology, capacity planning, automation, API’s and self-service portal capabilities that we hope introduce and seed great conversations at TechEX about next steps in this important community investment.

We invite you to provide input to the planning by joining us on Wednesday, October 16 at 2:10 p.m. for the Next Generation R&E Ecosystem: Interactive Session on Plans for Next Evolution of Internet2 Infrastructure session followed by by discussion break-out sessions at 2:40 p.m.

Tuesday, October 16, 11:20-11:40 a.m.

Next Generation R&E Ecosystem: Report on Workshops at University of Michigan

In June of 2018, the University of Michigan and Internet2 hosted two workshops in Ann Arbor, MI. The two workshops were a Network Automation workshop and a Network Connectivity to Cloud Providers workshop.

The the purpose of the Network Automation workshop was to discuss of the best practices for US universities and regional networks to automate network operations using orchestration software (e.g. Ansible, Salt) and single source of authority data sets (e.g. NetBox, Git).

The goal of Network Connectivity to Cloud Providers workshop was to identify current design requirements for connectivity to cloud providers, including support for data intensive science, migrating administrative functions to the cloud, and use of cloud-based third party vendors, to analyze potential connectivity solutions, and (potentially) to recommend best practices back to the community and Internet2. A high-level summary of the outcomes of the workshops will be provided during this session.

Tuesday, October 16, 1:40-2:30 p.m.

Next Generation R&E Ecosystem: Community Experiments Toward the Next-Gen Infrastructure

As part of the effort to help define the next generation infrastructure that spans the R&E ecosystem, a number of experiments have been in process during 2018 designed to flesh out models for providing end-to-end services focused on multi-institution science collaborations. This session will provide an overview of the efforts, explore the various challenges encountered both operationally and from a business case perspective, and explain how the insights gained will be used in planning the community's next infrastructure investment.

Tuesday, October 16, 2:40-3:10 p.m.

Next Generation R&E Ecosystem: National Research Platform (NRP)

This session will provide a brief introduction to the NRP (National Research Platform) Pilot effort, then focus on three key scaling issues that the team is considering.

First, based on the work the PRP (Pacific Research Platform) team has done with Kubernetes, it has become apparent that providing a consistent service environment on a national footprint for collaborating and sharing resources is important. While a number of services are already planned to be available (GridFTP, perfSONAR, OSG StashCache, etc.), a key design goal will be to provide the flexibility for campuses and regionals to provide localized services tailored to their needs.

Second, developing a robust, secure, high-speed R&E ecosystem-wide network service tailored to support science workflows introduces a number of scaling challenges for campus, regional and national network providers that need to be addressed in a uniform manner.

Third, this session will address what tutorials, hands-on workshops, and on-line workbooks can most help campuses and regionals and their users adopt the new technologies for monitoring/measuring and services for science workflows.

Wednesday, October 17, 8:30-9:00 a.m.

Next Generation R&E Ecosystem: Report on the Router Virtualization Pilot

Several pilot projects to inform the planning of the next evolution of the Internet2 Network were created based on discussion during the Tempe Connector/Network Member Principals’ Meeting in January, 2018.

One of the pilots is the Router Virtualization, intended to evaluate and report on the technical aspects presented by virtualized routing, including Juniper’s implementation of “node-slicing” and at least one other virtualized stack from both operational and logistical perspectives. During this session, the results of the evaluation will be presented and discussed with the community.

Wednesday, October 17, 9:20-9:40 a.m.

Next Generation R&E Ecosystem: Updating Policy and Configurations for Quality of Service

Today the Internet2 network doesn't offer QoS, all traffic via AL2S, AL3S, etc. is provided via a best effort service. As we more tightly couple both on and off campus services (e.g., extending local workloads so they are both in the cloud and local), what QoS capabilities are required, and how are they stitched together from campus to RON to Internet2, and beyond.

This session will provide a survey of the current state of QoS within our community, and seek input on potential future states.

Wednesday, October 17, 10:20-10:40 a.m.

Next Generation R&E Ecosystem: Report from the Routed Services Futures Group

As part of the Next Generation Infrastructure project, the Routed Services Futures group has been asked to review current Layer 3 routed services and determine next steps for future Layer 3 Services including classic R&E, peering, cloud and specialized VRFs.

Wednesday, October 17, 10:40-11:00 a.m.

Next Generation R&E Ecosystem: Adding Cloud Services and Layer 3 to OESS

Internet2's Advanced Layer 2 Service has been controlled by the Open Exchange Software Suite (OESS). As a result of using AL2S and Layer 3 VRFs (MPLS L3VPNs) as delivery mechanisms for the current Cloud Access pilot, Internet2 and the GlobalNOC have been prototyping changes to create L3VPNs on demand and dynamically add or remove cloud service providers direct connections (AWS Direct Connect, Azure ExpressRoute and Google Cloud Interconnect).

This talk will briefly discuss the Cloud Access pilot, OESS evolution, and future features that will be available, focusing on the current prototype of an Internet2 connection portal that has a new user interface, improved APIs, and additional statistics and monitoring for participants.

The UI changes include locating participants (including the cloud service providers) by name, in addition to the new monitoring. Time permitting, there will be a very short demo that shows the prototype operating on the live network. The prototype will also be demoed throughout the week in Coral Sea 2 (details found at https://meetings.internet2.edu/2018-technology-exchange/program guide/demonstrations/).

Wednesday, October 17, 1:40-2:00 p.m.

Next Generation R&E Ecosystem: Integrating Campuses Into the Regional Optical Platform

New optical platforms promise to provide bandwidth, flexibility and service agility, and are leading more regional networks to deploy them in pursuit of those characteristics. The link to the campus has now become the most difficult problem: fiber distance and availability; edge equipment flexibility and capacity, the need to maintain production-level support and the cost of all those things. NYSERNet's deployment of a new statewide optical infrastructure has included an exploration of the options for integrating the campus into that platform.

We will present the model topologies that we have already deployed, explore their capabilities and limitations, and talk about how we would like to evolve the campus-regional network.

Wednesday, October 17, 2:00-2:30 p.m.

Tutorials, Workshops, Demos and Other Advanced Networking Sessions


Tutorials and Workshops

Monday, October 15, 8:00 a.m. – noon

Network Automation Workshop

The Network Automation Workshop will provide a brief introduction to network automation using Ansible.  Familiarity with YAML and Jinja2 is helpful but not required.  Participants will need to bring a laptop and will be working with a virtual network lab. This workshop will provide a basic introduction to network automation that may be helpful for the afternoon Network Automation Hackathon.

Monday, October 15, 8:00 a.m. – 5:00 p.m.

Introduction to Kubernetes

Containers have shifted the way applications are packaged and delivered. Their use with cloud-oriented services, data science and machine-learning is skyrocketing with the beneficial side effect of enabling reproducible research. This rise in use has necessitated the need to explore and adopt better container-centric orchestration tools. Of these tools, Kubernetes - an open-source container platform born within Google -- has become the de-facto standard.

Kubernetes API-driven, highly extensible design has lead to its adoption by numerous vendors and projects. Powering the likes of Amazon, Google, Microsoft, and Redhat, it has truly delivered a single, platform agnostic API for managing infrastructure.

The aim of this tutorial is to introduce those application architects, developers, and system administrators who may already be familiar with container concepts to the architecture of Kubernetes. Through a series of lectures and hands-on exercises, attendees will explore the many facets of working in a Kubernetes environment.

These exercises will be augmented with discussions and demonstrations of various practical application deployments, with the goal of attendees being able to come away from the tutorial with the knowledge to begin to consume Kubernetes as a platform for their own programs and services.

Monday, October 15, 1:00-5:00 p.m.

Network Automation Hackathon

The Network Automation Hackathon will challenge teams to use automation tools to configure a specified network topology. Teams will be given access to a virtual network lab and jump host. The organizers will group teams based on indicated experience with automation.

Hackathon participants are not required to attend the morning Network Automation Workshop but may find it helpful, depending on level of experience.

Monday, October 15, 1:00-5:00 p.m.

Routing Security Tutorial

Protecting the research and education network is a team activity that involves the community of network operators, both campuses and regionals. Embedded security is one of the goals of Internet2's Next Generation Infrastructure. This tutorial gives a brief overview of risks to network routing within the R&E community and some examples of the impact of even a small, malicious routing announcement.

A global initiative that began in 2014, Mutually Agreed Norms for Routing Security (MANRS), takes one step toward preventing network attacks by taking on security as a shared responsibility between networks. Experts within the community will then give technical, hands on demonstrations of how to implement the four easy to implement activities that comprise MANRS, including uRPF, and RPKI. There will also be a talk from legal technologists from academia on how to overcome the legal and social obstacles to implementing RPKI.

Monday, October 15, 1:00-5:00 p.m.

Automated perfSONAR Provisioning with Ansible

This tutorial will cover the process for automated deployments of perfSONAR infrastructure using Ansible as a provisioning system. Participants will learn how to install and administer perfSONAR using pre-developed perfSONAR Ansible Galaxy Roles to author institution specific Playbooks. At the end of the class, participants will be able to quickly stand up and maintain their own arbitrarily large perfSONAR infrastructure using tools, scripts, and configurations presented in the class.
