Today we turn our attention to a somewhat older technology associated with ATM . It's a variation on the ATM User-to-Network Interface (UNI) that makes it possible to deploy multiple lower speed connections and have them perceived as a single cohesive Read More...

Packet networks come in two basic flavors: datagram or virtual circuit . Today, Mark is going to walk you through the definition of a virtual circuit, and examples of places where you can find them. You can listen to (or download) the PodSnack by clicking Read More...

A few weeks ago, we looked at Frame Relay. I suppose it makes sense to take a bit of time and explore asynchronous transfer mode (ATM). In today's PodSnack, Mark walks you through the basics. You can listen to (or download) the PodSnack by clicking Read More...

Let's go wrap up our discussion of Ethernet transmission rates with a look at 10 Gigabit Ethernet . This is still truly a backbone technology that is used in data centers, metro areas, links inside carrier networks, and storage applications. It is Read More...

Let's go back to a subject we started a couple of weeks ago: Ethernet transmission rates. We talked about 10BASE-T and 100BASE-T . Now let's step it up to the next transmission rate: Gigabit Ethernet . Although many people think of this as a "backbone" Read More...

Today I want to wander back to the world of ATM . ATM defines several different types of virtual circuit , and they have bizarre names like CBR , VBR , UBR , GFR , and ABR . So today Trevor and I are going to walk you through the difference between these Read More...

Sometimes, I am amazed at the number of very basic concepts that we simply have not talked about in this series. One of those jumped out at me as I was doing some update work on our wiki . We use the term frame all of the time, but we have never really Read More...

Since we talked about a Physical Layer option for Ethernet yesterday, I thought maybe we'd add another one today. So today we increase speed by an order of magnitude and we look at Fast Ethernet . This is quite probably the most common speed deployed Read More...

A few sessions ago, we talked a bit about terms related to Metro Ethernet . We talked about service multiplexing and we defined the term Ethernet virtual connection (EVC). Today we're going to bring those two concepts together and see how it gives Read More...

You want your traffic to be in better shape? No problem. A little diet. A little exercise. Those packets will be lean and mean in no time at all. Unfortunately, traffic shaping is not quite as easy as diet and exercise. (Actually, now that I think about Read More...
