The Brooklyn Bridge. 

The Arrival of IoT Heralds Networking Management from a Distance

What a network install on the top of the Brooklyn Bridge says about the impact of IoT on wired networks and the importance of remote device management.

One morning last summer, I was scheduled for one of the most unique network installs of my career. It was on the Brooklyn Bridge. 

It was a sunny morning with the wind blowing gently, and behind me was the Statue of Liberty. It was idyllic, but it was business; I had on a hard hat and safety glasses and as I stood on the historic bridge, which hangs from steel cables that are almost 16 inches thick. 

The Brooklyn Bridge, an iconic New York City landmark, spans 1,595 feet across the East River, connecting Manhattan and Brooklyn. It was originally built between 1869 and 1883, and today it sees traffic of more than 100,000 cars every day. The upgraded network equipment was to be installed at the top of the bridge, some 276 feet above the waterline. The New York City Department of Transportation assigned one lucky guy to go to the top of the bridge to access the enclosure that housed the networking equipment.

IoT Reveals How the Nature of Networking Is Changing

Along with the other members of the Transition Networks team, I was stationed in a trailer that served as the command point. We relayed IP address and configuration information up to the top of the bridge over a radio and watched the progress via a live video feed from the technician. The install went smoothly, even with non-network engineers doing all of the hands-on work. The only challenge came when the technician had to press the tiny reset buttons on some of the equipment to start the devices. Thankfully, he found a paper clip to help with the job.

This trip to the top of the bridge is an example of the how the nature of networking is changing, and how the Internet of Things is changing both wired and wireless networks. Industry experts anticipate billions of “things” will be added to networks in the coming years. Wireless networks are the focus of much of this activity, but IoT also has an impact on wired networks, because there are a lot of IoT applications where wired connections are better suited

Remote Management Reduces Requirements for Maintenance Trucks

Wired IoT applications include communications equipment, cameras, door locks, and digital signs. In comparison to wireless IoT applications, these systems are high-value, high-bandwidth, real-time systems, where constant uptime is critical. Both applications need power, and they need better management capabilities. 

Maintenance truck rolls have always been an expense that network operators want to minimize, but when devices are located remotely, the cost of dispatching a truck can increase significantly, and servicing those devices becomes more difficult. Through the use of remote management, operators are able to limit the number of truck rolls and be better prepared to address specific issues when they do have to dispatch service technicians. This will become even more important in the era of wired IoT. 

That was true on the Brooklyn Bridge. The new network will offer PoE++ (the latest standard of Power over Ethernet, which allows for greater amounts of power) to support the new wired IoT systems being installed on the bridge. The new systems replace existing equipment to provide better communications, security and functionality, but require higher power levels.

New Capabilities Enable Troubleshooting from Afar

The other key feature driving the new network was remote troubleshooting of the equipment. The effort it takes to access the equipment makes rebooting or fixing the gear at the top of the bridge one of the most difficult truck rolls.

The installed switches come with device management system software that provides the advanced tools necessary for total management of all powered devices. DMS provides discovery and mapping of powered devices, allows for troubleshooting of cable and IP connections, and enables the cycling of the powered device. So, by using the DMS instead of a making a harrowing climb to the top of the bridge, the equipment can be rebooted, adjusted and managed — all from a mobile device in an office in Brooklyn. It’s the kind of capability the city wants at all 13,000 traffic intersections across the five boroughs. 

And it’s the kind of functionality that is becoming increasingly important in enterprises of all kinds.
