Choosing a Rugged Ethernet Networking Solution
Mission-critical defense and aerospace applications rely on the power and effectiveness of rugged Ethernet networking solutions. But, these solutions come in many varieties with a host of features to choose from. As a result, there is a wide range of factors to consider when choosing the optimal Ethernet networking solution for your program and application requirements.
The form factor is the first consideration and one that you may have already determined when you start evaluating Ethernet switching and routing solutions. In some cases, a line replaceable module (LRM) is the right choice because it can be easily inserted into existing systems and individually upgraded without replacing the entire system. In other cases, a standalone subsystem or line replaceable unit (LRU) is the right solution. In addition to choosing the appropriate form factor, it’s important to also carefully evaluate the functional and technical aspects of the equipment. This white paper explores the key aspects that need consideration to enable you to develop the right combination of Ethernet switching and routing capabilities for program, platform, application, SWaP, and budget.
