At the IIR WDM & Next Generation Optical Networking event in Nice, France, this week much is being said about the evolving networking landscape. Optical networks used to be responsible for moving data rigidly from one location to another, straightforward A to B. These transactions used to be stable and predictable, long haul or metro. But this is no longer the case. #Anywhereization, end users’ demand to access anything, anywhere, anytime and on any (synchronized) device is having an enormous impact on data patterns. In fact it’s game-changing.
A shift to mobile devices, the continued rise of video, increasing datacenter-to-datacenter connectivity and exponentially more data are some of the results. This data impacts networks in new ways. For example a single transaction, like your tweet or status update, may well pass through four or more data centers. And those data centers, which used to sit in the metro, can now be anywhere from northern Sweden to North West California.
This growth is also unpredictable. The erratic character of today’s bandwidth demands could not have been foreseen a decade ago. In the ‘old days’ capacity planning was about managing bandwidth with relatively flat and predictable curves. Today’s networks need to accommodate more fluid network consumption patterns. These changing peaks in demand are sometimes enormous and overlapping, requiring huge bandwidth resources.
As an international carrier with 1,000 communications service provider customers, TSIC is well positioned to see networks volumes going up with revenues driven down. Carriers and service providers can no longer continue to do ‘more of the same’. We have to adapt – add value that supports new business models and an instant ability to turn up both new capability and capacity. In this way we can support new innovations and the growing number of disruptive services and applications. After all, despite the peaks being challenging to accommodate, they also carry our new ideas and offer opportunities.
The need for the network to evolve is clear. It has to become more dynamic, flexible and scalable; able to respond to these changes and provision new services in moments rather than months. This new approach is more than developing new business models; it needs to center around the customer – driving end-user satisfaction and retention.
We have just announced that we are working with Ciena for the pan-European segment of our global fiber network to create a scalable and flexible OTN-based global network that promotes our vision to support service providers with bandwidth- and network-on-demand transport services. As such our network can not only meet the bandwidth demands of today, but also ensures the bandwidth demands of tomorrow. After all, not being able to predict the demands on the network in the future doesn’t mean that we can’t be ready for them.
