Network Operations

The network is extensively monitored and recorded to ensure maximum availability and peak performance

Our Network Operations team monitors traffic 24 hours a day, seven days a week, 365 days a year to ensure that the network's high-performing capabilities are available to users when they need it. 

How we monitor and record network performance

As a passive measurement, Simple Network Management Protocol (SNMP) interface statistics, both bytes and packets per second are recorded and viewed by modified Multi Router Traffic Grapher (MRTG) graphs. Error and Discard Statistics are also kept.

As Netflow is deployed at each Point of Presence (PoP), traffic is measured down to each Internet Protocol flow. The results of these are displayed as tables or graphs recording bytes, packets and flows per second.

With active measurement, Internet Control Message Protocol (ICMP) packets are sent betweenRegional Network Operator sites and to other points at regular intervals to measure network performance.

Other measurements, employing User Datagram Protocol (UDP) packets are also used to measure Quality of Service (QoS) issues.

Network links and services are also tested for availability at very regular intervals.

Network Operations Centre (NOC) Help Desk

The Network Ops team also operates a 24x7 Network Operations Centre (NOC) support service for customers and partner organisations to report faults and issues affecting network performance. Our aim is to resolve any network performance issues as quickly and with as little impact on customers as possible.

Service Status

If you're experiencing issues with the performance of CloudStor, eduroam, Panopto or Zoom, please check the AARNet Service Status page to find out if there is a known operational issue degrading the service or taking it offline.

The AARNet Network Operations Centre (24x7 NOC) Help Desk is a service for AARNet customers and partner organisations, to report network faults and conditions that may be affecting network performance.

Staff and students should contact the network managers at their own institution or organisation if they are having difficulties.

The NOC is attended 24 hours, seven days a week (24x7) by AARNet staff, who will answer your call and respond to email enquiries.

Note: In the event of call congestion, or other issues, your call may divert to a back-up call centre.

You may also email the NOC Help Desk which is also monitored 24x7, however, the response is likely to be slower than using the Help Desk phone service.

AARNet's process for resolving network issues

A NOC operator will answer your call and request information about the fault:

  • What area are you calling from? (e.g. which State or Territory)
  • Your name
  • Your organisation
  • Your contact telephone number
  • A brief description of the fault
  • Approximate time the fault occurred

The operator will immediately log a trouble ticket and engage the most appropriate AARNet staff member to resolve the fault and you will be called back to discuss the situation further or to let you know that the issue has been resolved. An escalation procedure is in place to ensure that faults are dealt with promptly.
