The wave of virtualization is catching up in every vertical of technology, and new protocols are being defined to improve functionality and management of emerging technologies. Software-defined Networking, or SDN, is one of those technologies. SDN was first used in data centers to configure network devices connecting virtual machines amongst themselves and the internet on a massive scale and is now being adapted into other applications and technologies.
The commissioning process for microwave—from integration to testing to equipment configuration to turn-up—can be lengthy and can involve multiple teams at multiple sites and get more complicated as microwave moves to include more sophisticated Layer 2 and Layer 3 capabilities. With added complexity, configuring intricate radio parameters in the field can increase labor-intensive operating procedures, increase operating costs, and unfavorably affect an operator’s return on investment and bottom line.
Software-defined networking (SDN) promises to drastically simplify how transport networks deploy, operate and get serviced. Reducing OPEX remains a significant factor for implementing software-defined networking. Automating service creation, traffic and bandwidth control, and network management as well as reducing maintenance complexity of routing protocols remain areas where it will simplify backhaul and lower OPEX. The only questions seem, “When will this happen?” and “How much will it save?” And what about CAPEX? Can we expect reduction in purchase price of microwave backhaul based on such a migration?

Without becoming reality, 5G mobile communications have already captured the imagination of operators and technology providers. So can the general public catch up with the hype soon? We’ll see. Meantime, behind-the-scenes mechanics of prepping for 5G continue, building on prior technologies. At each step of the evolution of backhaul infrastructure, different challenges cropped up.
Aviat Networks Chief Product Officer Ola Gustafsson talks about SDN 5G backhaul during AfricaCom 2016.
The most pressing business need in many networks deals with delivery of new services.The biggest evolution today in the backhaul network is the trend toward integration of IP/MPLS intelligence into microwave. Software-defined networking (SDN) remains another more recent trend in backhaul. However, as we’ve posted many times, integration of IP/MPLS intelligence into microwave systems provides a number of benefits. These include lower cost, fewer boxes to buy/deploy/maintain and better network performance overall such as lower latency and better reliability.
