Telstra, Ericsson and Ciena say they have successfully encrypted in-transit data at a rate of 100Gbps at the network layers across multi-vendor networks, covering 21,940km between Los Angeles and Melbourne over the Unity and Australia-Japan submarine cables and Telstra’s domestic terrestrial network.

The demo, using Ciena encryption technology, was in preparation for Telstra offering network layer encryption as a commercial service.

Emilio Romeo, head of Ericsson A/NZ, said Ericsson had provided end-to-end systems integration expertise to support the demonstration, adding: “A series of advanced demonstrations such as these are necessary before any product is released commercially.”

According to Ericsson: “While encryption solutions exist today to protect data when it is ‘at rest’ (at the start and end points), this trial demonstrates the advanced security that can be delivered while data is in transit …without any impact to performance.”

Darrin Webb, Telstra’s executive director of international operations, said a commercial offering would enable customers to protect their data, not only at the application layer, but also at the network layer without quality loss.

Telstra has given no indication of when it might launch a commercial service.
