Per tunnel and adaptive QoS
- [Instructor] In this lesson, we're going to talk about advanced quality of service techniques that require a hub and spoke topology. Now we have headquarter locations or data center locations that have enough bandwidth to satisfy all the remote branches' locations. So in the diagram below, we have a 1 gigabit circuit at our edge, which is acting as a hub, and then we have all our branches which have 100 megabit circuits. So we have sized up the hub location so that we can satisfy the need of 10 of our branches or spokes when they're at full capacity. Now, oftentimes we're at a hybrid model, so we can actually accommodate more of the spokes when they're actually at partial connectivity. Now the problem exists with the fact of that the large WAN circuits at the actual HQ location can saturate the branch's capacity. So the example is, is imagine I've got a host PC over here at Edge2. And so he's doing an FTP transfer to a server back here at the actual HQ location. And so the FTP…
