In many of our reviews, we comment on a device's support for gigabit Ethernet, as well as whether it supports jumbo frames. But what are jumbo frames and why should you care about them? In basic terms, a jumbo frame is any frame larger than a standard Ethernet frame. Their main value is that they can dramatically improve network performance by raising effective bandwidth.
Jumbo frames can be a bit of a challenge, though, as there are multiple sizes, interpretations, and technologies, making it difficult to fully understand and leverage their value, as well as fully integrate jumbo frame devices into your network. The goal of this article is to explain jumbo frames and help you determine if and how you can use jumbo frames in your network.
