To help curb some of the bandwidth pain, Jim MacLeod of WildPackets identifies common issues and illustrates how to identify and overcome them.
The bring your own device (BYOD) trend not only raises a security issue, but can also slow down the local network. Consumer-grade devices are designed for small networks, and their discovery protocols can send multicast that floods the entire subnet. Rather than banning BYOD, create a BYOD or guest Wi-Fi network in an external DMZ. It will let your users check their email without slowing down their neighbors.
