As mobile and video traffic continue to explode, broadband fixed network builds expand, and big data keeps getting bigger, the ongoing need for networks to scale in capacity is clear.
Let’s take a quick look at the numbers:
•Global IP traffic is poised to increase threefold over the next three years.
•Data usage is doubling annually in some markets.
•Mobile data traffic between 2012 and 2017 is forecast to multiply by 13 times.
•Metro traffic is expected to see more than 560 percent lift in that same period.
•The proliferation of data centers in the metro will see more traffic terminating within the metro as opposed to the backbone. In 2012, just more than half (57 percent) of traffic terminated in the metro, but by 2017 that will represent three-fourths of traffic.
All this helps explain why 100G optical networks, which seemed to many observers not that long ago as a futuristic idea even as they were being introduced, are now standard. Yet demand is already outstripping the capacity of some of these networks.
But while it’s clear that the need for networks to scale continues, the problem is that estimating the ideal capacity around which to engineer networks has always been a combination of art and science. That creates challenges because network operators need to make sure they have the network resources in place to meet demand, while being strategic about where they invest to avoid too much risk.
The good news is that new agile, scalable, and SDN-ready 200G optical networks can now enable network operators to mitigate risk and ensure they’re ready with network capacity when customers are.
As Earl Kennedy, who is involved with IP transport product marketing at Alcatel-Lucent (News - Alert), noted in a TechZine posting, Align 200G optical network capacity with demand, rate adaptive technology like that described above simplifies operations by automating provisioning. It enables users to expand fiber capacity from 8.8. to 17.65 with the touch of a button and without new hardware. SDN functionality comes in by allowing the network to respond to unpredictable traffic, and quickly. It does that by providing multilayer resource discovery and control, and dynamic path selection, Kennedy notes.
The Alcatel-Lucent 1830 Photonic Service Switch allows for all that. The 1830 supports next-generation WDM multiservice transport from access to core; addresses a wide range applications and services, including Carrier Ethernet, mobile backhaul, and multicast video; and puts network operators on an evolutionary path from 100G to 400G transport.
The rate adaptive 100G/200G line card for the 1830 recently received a Lightwave Innovation Award from Lightwave Magazine, garnering a 4.5 rating out of possible 5 from an independent panel of industry experts from the Fiber Optic Association, Current Analysis, LightCounting, Ovum, Verizon (News - Alert), and Cabling Installation & Maintenance magazine.
“The new module is the first to provide 200G transport in the same package as 100G. It saves cost, space, and power for metro/regional applications. This is important for metro operators as traffic demand and demand for 100G client interfaces are increasing,” the judges commented of the line card, which lets service providers more than double the bandwidth capacity of their networks with the flip of a switch.
