Webinar details

Have you ever needed to size a network link but were at a loss for how much bandwidth to allocate? Yes, we have too. There aren't any simple algorithms to determine link bandwidth sizing. The result is that links are often grossly over-capacity, which wastes money.

We are going to talk about methods of determining link utilization and link sizing. Some of the discussion will be about how transport protocols work and how to look for and measure link congestion. There will also be some examples of congestion we've seen, the analysis in each case, and the resulting solution.

The case studies are really interesting, partcularly the "Storage 10G to 1G" one. One of my customers is facing a similar issue, and I am now able to explain what is going on :)
