Completely Online Event Offers Hands-on Training in SDN, Science DMZ, DTNs, perfSONAR, and Science Engagement
Date: 21-22 June 2017
Available completely online!
Connection information will be shared with registered attendees. Please share with members of your campus community!
No registration fee!!
ESnet, Indiana University, and Internet2 are hosting a completely virtual version of the Operating Innovative Networks (OIN) workshop on June 21-22 2017. The series is designed to help lab and campus network engineers deploy next-gen research networks that can effectively support data-intensive science. Sessions will be available throughout the day on the topics typically presented in an in-person workshop, but will be modified for the virtual audience. Due to timezone considerations, the presentations will run between 6am EDT and 6pm EDT over the two days, and will also be recorded for future use.
The workshop will consist of 2-days of material for building and deploying Science DMZs, Software Defined Networks, perfSONAR, Data Transfer Nodes, and Science Engagement. The content will be particularly useful for NSF Campus Cyberinfrastructure awardees that are being funded to upgrade their networks with these technologies, or those looking to prepare for the next CC* solicitation. By the end of the event, attendees will have a better understanding of the requirements for supporting scientific use of the network, architectural strategies that can simplify these interactions, and knowledge of tools that can mitigate problems users may encounter.

This workshop will be completely online, but we are asking participants to register so we can share information about connectivity and materials.

There’s recently been a lot of bad news about network congestion, etc. So I thought it was time to share some good news :-). Over the last couple of months, we have made a number of changes and improvements to the South African eduroam roaming service.
Most significantly, last night we completed the replacement the two federation-level roaming (FLR) servers. More than simply an upgrade, this change represents a complete change in architecture, different hardware, and different physical locations. The new architecture has four instances (two active; two standby) of the FLR servers in two different cities (Cape Town & Jo’burg), providing both geographic redundancy and improved resiliency. Fail-over between the active and standby instances is handled by BGP route announcements, and should typically take no more than a few seconds.
We’ve also introduced some courtesy monitoring as an experimental service. This has already helped three institutions detect problems that would have prevented their users from being able to roam successfully. In future, it will hopefully provide institutional help desks with better insight into what happens when their users are roaming on another campus and help them to be more proactive about problems with their service. You can find out about the monitoring system and the status of your realm at https://eduroam.ac.za/status/.
The infrastructure changes should (hopefully) make the eduroam roaming service more reliable, which is important since South Africa now sees in excess of 165,000 inter-institutional authentications a day. I’m hoping to be able to make some stats available in due course.
The web page at https://eduroam.ac.za/ has been updated, and we’ve introduced several new features. Institutional administrators can now update their site details, and in doing so provide end users more accurate information about what to expect when roaming (the data provided on the South African eduroam website also feeds eduroam.org and the monitoring system). Administrators can now also self-provision for eduroam CAT — the configuration assistant tool that provides a simple on-boarding installer to help end users configure their devices. Institutions are strongly encouraged to take advantage of CAT to make connecting to eduroam easier for their users. (See https://cat.eduroam.org/ for more info.)
All of these changes were made as part of the service handover from the SANReN Competency Area to TENET, and represent a join effort by both teams and the culmination of many months of cooperation to ensure a seamless transition. I’d particularly like to thank Simeon Miteff and Johan Hugo for their significant contributions.
Please note that TENET is now responsible for maintaining the infrastructure underlying the eduroam service. This means that going forward you should report service problems via the TENET SOC.

Dear beneficiaries and partners
You are cordially invited to attend one of two workshops on
Data Transfer & Operating Innovative Networks
What? This workshop will offer presentations and demonstrations of the science DMZ architecture, data transfer nodes (DTNs), data transfer tools (like GridFTP and Globus) and perfSONAR for network performance measurement and monitoring. “Combined, these technologies are proven to support high-performance, big data science applications, while ensuring the security and availability that modern campuses and laboratories need”1. By the end of the event, attendees will have a better understanding of the requirements for supporting the scientific use of the network, architectural strategies that can simplify these interactions and knowledge of tools that can mitigate problems users may encounter. Detailed agenda attached.
3 May 2017 – eResearch Conference at University of Cape Town [R500pp; limited sponsorships available from SANReN for selected, eligible beneficiaries]
4 May 2017 – Council for Scientific and Industrial Research (CSIR), Pretoria [free for SANReN beneficiaries / TENET customers]
Who should attend?
a. IT network engineers/technicians from universities, science councils and supporting institutions interested in optimising the network; eResearch / science engagement officers; researchers and scientists with big data transfer needs/challenges.
b. Eligible beneficiaries interested in participating in a SANReN science DMZ and/or DTN proof of concept.
