Get your wireless donut right

Did you ever experience that your brand new wireless Access Point (AP) does not deliver as strong signal in your house as you expected? I did. Short investigations revealed details useful not only for fixing your home wireless network, but also for designing stable enterprise wireless environments. Putting configuration issues aside, one of the reasons […]

Road Planning is like Network Routing

Currently studying Huawei, I came across Garp Vlan Registration Protocol (GVRP) as a mean to do Vlan administration and pruning. Having no prior experience with it, I run a quick investigation. Cisco VTP is the proprietary counterpart of GVRP, but not all features have direct match: VTP appears to be richer and more mature. First thing […]

Approach to running an IPv6 Pilot

Let’s look at deployment scenarios first. For majority […]
