Research network engineering (RNE) community group

A community for sharing best practices in building network infrastructures to support cutting edge research.

Facilitated by Jisc

Open to staff from Janet-connected sites involved in network operations or in communities conducting data-intensive science

Monthly meetings via Zoom

About the community

Researchers at Janet-connected sites often have challenging network requirements. One notable case is an ever-increasing need for them to move large volumes of data to other organisations on the Janet Network or beyond.

The systems and network engineering knowledge required to design, build and operate effective platforms for such data transfers is not insignificant.

The broad aim of the RNE community is to discuss and share best practices in research networking, bringing together those with experience in the area with those who may be new to the subject, along with engineers and performance specialists from Jisc.

Topics might include examples of Science DMZ implementations, how to gather network performance measurements, and comparisons of software transfer tools. Ultimately, we hope to enable all Jisc members to make optimal use of their Janet connection to support their research requirements.

Aims of the community

Our aims are to:

  • Present and discuss examples of network engineering practices in support of research
  • Discuss the tools, software and concepts behind Science DMZ principles
  • Arrange and report on data transfer tests in varying scenarios
  • Explore new technical solutions
  • Foster collaboration between communities, within Janet and internationally

These aims will be discussed and updated at the group's first meeting. The RNE community will meet on a regular, monthly basis to allow members to share and discuss ideas, best practices and any issues they face.

Who should join

The community is open to:

  • Network managers
  • Campus network engineers
  • Campus IT staff supporting data intensive research
  • Members of research communities seeking to share large volumes of data

No prior experience in the area is assumed.

perfSONAR release 5.1.0

Date and time: Friday 24 May 2024 at 2pm (UK)

We will hear from Andy Lake from ESnet about version 5.1.0 of perfSONAR which is shortly to be released.

Register in advance for this meeting.

After registering, you will receive a confirmation email containing information about joining the meeting.


perfSONAR is a network measurement toolkit designed to measure network characteristics over paths spanning multiple administrative networks and domains and assist in identifying and isolating network problems. A typical perfSONAR node can be used to measure throughput, loss, latency and paths used, and record these over time to support analysis of current and historical measurement data.

The perfSONAR development team will discuss perfSONAR 5.1.0 which is available as a beta release and should be available as final release in the next few weeks. This release introduces new visualisation to make navigating measurement results easier, support for faster throughput tests using threaded iperf3, support for new operating systems and more. The talk will discuss how to try the beta, the process to update existing deployments and look further ahead to the roadmap beyond 5.1.0.
