There's always lots of talk about mobility and WiFi security, but not much about the internal infrastructure IT organizations need to support, maintain and manage today's growing wireless networks. That's why an article [1] at NetworkWorld caught my attention as it focuses on how some enterprises are managing Voice over Internet Protocol (VoIP) deployment. While it used to be a matter of just monitoring network stability and determining bandwidth needs, today's networks also requires specific tweaking to boost voice applications and ensure top performance. It's an interesting and unique insight into the growing responsibilities of network administrators. -Judy [2]
