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 […]

Traditionally network monitoring of properties such as traffic levels through an interface has been done by using SNMP-based polling of network devices.

To be precise, ¾ of the new Midlands access network is a go. We’re still battling to over come some significant delivery issues in the far east of the region, but the majority of the new infrastructure is now built, commissioned, and ready for service. We’ve also been working through some management system issues over […]
Over the past week we’ve completed the first phase of commissioning of our new London access network, and have started migrating member connectivity over to the new infrastructure. The lucky first institutions were Stanmore College, Bromley College, and Christ the King Sixth Form College, and there are plenty more to come. The new network offers […]
