Alcatel-Lucent has unveiled new software defined networking (SDN) technology that, it says, will overcome the limitations of today's networking technologies in highly virtualised data centre environments.

Software defined networking (SDN) all the rage, but most of the buzz has been around its application in data centres. Ericsson is promoting the concept to increase the efficiency of service providers' networks and is promising to release its first telco SDN application - developed with Telstra - later this year.

Juniper has laid claim to leadership in the rapidly emerging field of software defined networking with announcement of its comprehensive vision for the architecture of SDN technology. Others however question whether what Juniper has unveiled is in fact SDN at all.

The application of software defined networking technologies to telco networks is gathering momentum: Cyan, Ericsson and Huawei touted their products and expertise within days of each other.

A handful of the world's leading telcos, including Telstra, have got together to set up an industry group under the auspices of global standards body ETSI to look at virtualising telco network functions, presently implemented in dedicated hardware and software.

Software defined networking technology must be expanded from the control of switches and routers in data centres into telco networks where it has the potential to lower costs and create new opportunities for network operators, according to Ericsson CTO Ulf Ewaldsson.

Japan's telco giant, NTT Communications (NTT Com), is to launch the world's first global cloud computing service to incorporate OpenFlow network virtualisation technology that will enable customers to control and configure their network within and between data centres.
