perfSONAR enters the Grafana age

The perfSONAR toolkit is an open source network measurement package designed to provide multi-domain network monitoring and establish end-to-end network usage expectations. It has proven popular in research and education networks, particularly for communities who move large volumes of data over significant distances. For example, sites taking part in CERN’s Worldwide Large Hadron Collider Computing […]

Writing this as I sit at Schiphol airport waiting for my delayed flight (due to snow, there was barely a dusting) back to Heathrow. Some reflections on 2 days spent in Amsterdam with peers and colleagues from across Europe. GÉANT GÉANT is the pan-European network for the research and education community. It connects Janet and roughly 40 […]

The Move from Member to Jisc

A while back, after almost a decade of making (and sometimes breaking) networks at a university, I began searching for the next chapter in my career. My past experiences have been with large network vendors, small resellers and end customers, but never a service provider. The connection with the sector I’d grown to know and […]

Your next step in network defence — the Janet Security Policy. Seriously.

Protecting networks, systems and users isn’t getting any easier. Whether it’s nation states looking for intellectual property to steal; criminals looking for ways to make money through ransomware or scamming users; or students launching denial of service attacks in the modern equivalent of setting the fire alarm off to get out of an exam, the […]

Is it time to consider streaming telemetry?

Traditionally network monitoring of properties such as traffic levels through an interface has been done by using SNMP-based polling of network devices. With such polling typically performed every five minutes the resulting plots will produce 5-minute data samples, so the traffic level shown over time, and the maximum rates seen, will be an average for […]
