There’s more than one way to migrate a metro network from 10Gbit/s aggregated bandwidth to 100Gbit/s. At first, you might consider data center leaf/spine switches, expecting significant cost savings from volume-deployed devices. However, on second thought, there may be some concerns. Those devices are optimized for a very specific application, which doesn’t necessarily makes them the perfect solution for other use cases ...

Synchronizing distributed network architecture is a major challenge. Highly accurate phase delivery at aggregation sites is becoming more and more vital with the growth of IoT and the emergence of 5G applications. But the aggregation site can be a tough environment for grandmaster clocks. Firstly, it requires timing technology with new levels of power, size and cost optimization, integrated with a highly scalable network management system. Grandmasters need to be ruggedized and able to operate in wide temperature variations. And, most importantly, they need a backup plan ...

Communication service providers are adopting a range of approaches to 5G. Some are focusing on fixed wireless access as a substitute to copper or fiber transport. Others see huge opportunities in accessing sensors with new narrowband radio access technologies such as NB-IoT and LTE-M. There is also great value in end-to-end virtualization, aka slicing, for offering customized private mobile networks to enterprises and governments ...
