Software-designed networks are poised to make another leap forward, which is good news for small cells.
Virtualization of networks is something that carriers have shown keen interest in of late. The reason? Virtual networks have the potential to reduce, drastically, the cost of small cells and dramatically shorten the time it takes to deploy them.
At the forefront of this technology, Huawei has developed a prototype that can dynamically create “multiple virtual networks on demand to meet individual tenant needs – all from the same physical network.” This is news. They claim that the system’s flexible optical network control design will allow for automatic on-demand adjustment in modulation format and line-rate based on need; and the network health analysis application is designed to track network resource utilization, key performance indicators and alarms in real time.
If the prototype lives up to the hype, Huawei stands a good chance of capturing a piece of the estimated $35 billion per year market by 2018, as predicted by SDN Central, which projected the sector could grow by three-fold next year and will continue its expansion 10-fold by 2018.
