About the Network

Configuration

Telstra Internet Direct‘s domestic Internet backbone in Australia interconnects with one of the world’s leading global Internet/IP backbones operated by Reach Inc., a Telstra joint venture company, providing you with an extensive level of global Internet connectivity, reachability and performance. Click here for details of the global Internet network.

Telstra Internet Direct domestic/global network interconnectivity is seamlessly provided through resilient, diverse multi-Gigabit bandwidth Points-of-Interconnect (POI) in Sydney and Perth.

Domestically, Telstra Internet Direct provides a 2.5 Gbps inter-capital network, with an active redundant 2.5 Gbps network. The Points of Presence (PoPs) within each capital city are linked via two 1 Gbps links. Inter PoP links in Sydney, Melbourne and Brisbane are currently being upgraded to 10Gbps.

The current configuration of the Telstra Internet Direct backbone is shown below

Points of Presence

Telstra Internet Direct provides Points of Presence in each Australian capital city, offering you increased coverage (reduced access costs) and greater reliability. PoPs are located in facilities specially equipped to support modern telecommunications equipment, including non-stop power and security.

Telstra Internet Direct is continually in the process of increasing the number of national PoPs. This will take in major rural centres, and in turn, allow your network to extend further afield.

The locations of the current PoPs are set out below:

Network Availability Level

Telstra will use best efforts to ensure the Network Availability is no less than 99.85% for any Month.

How is the Network Availability of the Telstra Internet network monitored?

TCP-based sessions are established between reference devices and measurement processors. The reference devices are located in every PoP in the Telstra Internet network, and the measurement processors are strategically located in the network so that any failure of the network will be visible as a failure of one or more of the TCP sessions. Some measurement processors may also act as reference devices for other measurement processors.

Diagnostic packets are regularly transmitted within any of the TCP sessions, and these packets are used to determine the state of the session. If a measurement processor fails to receive three diagnostic packets in a row, the session is cleared and the failure of that session is logged. Periodic attempts will then be made to re-establish that session, and the eventual reestablishment of that session will also be logged.

The timers governing both the transmission of the diagnostic packets and the session reestablishment attempts are set to a level that allows the detection of the failure or reestablishment of a session within one minute. The session will be considered to have failed for the total amount of time between failure detection and reestablishment detection in which the failure and reestablishment are actually detected.

The logs of these TCP sessions are periodically processed, and any failures of the TCP sessions are correlated and assessed against criteria determining whether they constitute unavailability of the core intercapital network or of the network connecting the core intercapital network to the regional PoPs, and the total number of minutes for which the relevant part of the network was unavailable is logged.

At the completion of each month, the percentage network availability is calculated according to the number of minutes logged of unavailability for the month, for the core intercapital network or for affected regional network as appropriate.

If logged minutes of unavailability are found to have been the result of either scheduled maintenance work ("Scheduled Outages" under Our Customer Terms) or failure of the equipment (the reference devices or measurement processors, in which case the network will not actually be unavailable but just appear so to the measurement systems), then these minutes will be excluded from the calculated monthly percentages.
