At MilSource, our technical team often get questions on how to more easily manage the “networks” now living and communicating on every mobile military vehicle. Implementation teams and integrators are faced with the daunting task of managing hundreds of networks that are the same set of devices just repeated in every mobile vehicle.

10 Gigabit Ethernet (GbE) has been the standard in data centers, enterprises, and service providers for years, and 10 GbE over fiber has become the normal physical medium to deliver these speeds in “sterile environments.” Now, however, applications such as video, LiDAR and sensors are driving the need to deploy 10 Gb Ethernet data speeds on field-deployed mobile military platforms.

Because customers need to simplify and economize on space, many networking companies are being asked to move beyond traditional networks and look at ways to combine networking and power management. You’ve got devices that need to share data, but they also need to be powered. If you are looking at a mobile military platform, Power over Ethernet (PoE) simplifies cabling and reduces the number of devices needed on a platform.

The same thing is applicable to dismounted soldiers. But they come with an added challenge: different devices from different manufacturers—all needing to communicate with each other—using USB or Ethernet. They all also need power but use portable batteries every one of them—and this creates a dilemma. Weight, battery management, ongoing power needs. All challenges for the dismounted soldier.

Today we are going to discuss timing and synchronization of devices on an Ethernet network. Synchronization of packet cadence is necessary for time-sensitive applications work like they’re supposed to.

Ethernet is considered (for the most part) a non-deterministic networking scheme, using “best effort” and requiring handshakes and confirmation. While this makes it inherently reliable, it also makes Ethernet natively unsuitable for time-sensitive applications — such as voice/video over IP, robotic (motion) control, industrial automation, etc. — that require real-time communication or time synchronization.

While soldier-carry wearable devices have their own batteries, a centralized power source (usually a Lithium ION battery) is carried to recharge those devices. And, of course, these batteries must be either replaced as they lose charge or recharged by an external power source—the preferred scenario to keep both individual and platoon burdens lower. In this later scenario, Soldier-worn Integrated Soldier Power and Data Systems (ISPDS) must be able to manage both the charge to each wearable device and the recharge of the Lithium batteries.

The modern soldier is fully equipped with advanced weaponry and communications systems (weapons with sensors, night vision, navigation systems, smart phones and more) all of which require power and must be able to communicate with each other. The data sharing required between just one soldier’s devices has created the concept of a personal area network (PAN) that shares and gathers data, and then distributes that data with other platoon members or to central command.  Integrated Soldier Power and Data Systems (ISPDS)– also be known as Soldier Worn Power and Data Hub, Tactical Soldier System, and several other terms– enable simultaneous data networking between the devices and  power management to keep the devices running. In short, ISPDS delivers both PAN traffic and power management in a single device.

VPN

Virtual Private Networks (VPNs), when used properly, are a great tool for managing data and network access and, thus, reducing data security risks. VPNs are extremely useful for three key reasons:

• “Spoofing” a location so that ISPs don’t track your location and browsing history
• Limiting cybercriminal exposure by encrypting your traffic–even on public Wi-Fi networks
• Encrypting log files and browser history to limit surveillance exposure

Embedded Ethernet switches have become a staple in military, industrial and automotive applications. For any of these applications, space, performance and reliability have always been key evaluation factors. Typically, embedded Ethernet switches come equipped with 4, 8, 14 and even up to 24 ports on a compact form factor—usually smaller than 4 inches by 4 inches. Embedded switches come in two flavors: managed or unmanaged. If you missed our blog on why you would need managed versus unmanaged Ethernet switches, please check that out here.
