Why do my WAN links slow down?
WAN links have been around for many years and they continue to be one of the most critical parts of any IT infrastructure. When I first started my career as a network engineer in the nineties, link speeds of 32Kbps were not uncommon. Thankfully we have moved on from this and link speeds of 10Mbps+ are not uncommon today. However, for most networks, bandwidth on WAN links is still limited, due mostly to the expense of upgrading to higher link speeds.
