In discussions about an Ethernet-based architecture, the concept of “fabric” often comes up. In many ways, fabric is a perfect analogy for how all the connections in an Ethernet design are woven together, just as tiny threads of cotton fiber are woven to create textiles. In the end, fabric can take many different shapes, but its underlying structure is consistent and, if woven correctly, builds a very strong composite. Ethernet fabric, in fact, is the very composition of similar and dissimilar data flows that define a set of functions in and around themselves.
As an AIMS member company, Utah scientific is excited to help chart the next generation of IP media solutions. We are continuing to leverage our deep and broad expertise in today’s SDI technologies to deliver solutions like our foundational UHD-12G 4k router platform, while at the same time pushing the boundaries of uncompressed IP audio, video and data. In our earlier paper, IT Essentials, we covered the basics of IP, addressing subnets, gateways, and other elementary concepts. This paper will focus more on the overall audio and video architecture as it applies to uncompressed video streams and how they function in an Ethernet fabric. That’s a lot to cover, so let’s get started.
