And he's right. Why is he right? Because he got in front of the folks who actually _can_ manage this problem, and that is the people (actually the NGOs) who have the monetary and fiduciary duty to begin looking at problems at the financial loss level.

tracking fiber assets
by Daniel J McDonald 15 Feb '07

15 Feb '07

What do people use to keep track of fiber-optic assets? We own fiber on electric transmission lines - a hundred spans or so, mostly 24-48 count, about 800-900 total route-miles. But we lack a tool to keep track of what is in use, which customers would be affected when we perform maintenance, and the like. Any suggestions for good tools to manage this would be most appreciated. Our spreadsheets, CAD drawings, and directories full of OTDR shots are just not cutting it. -- Daniel J McDonald, CCIE # 2495, CISSP # 78281, CNX Austin Energy http://www.austinenergy.com

The IETF experience is that enough people run 802.11a to take significant load off of the {b,g} network.

If you forced your customers use 802.1X for authentication they wouldn't get an IP address unless they were authorized. If 802.1X is not in the mix, another solution is to give them a very short lease (say 2 minutes) until they've completed web-based authentication, and then give them the one-hour lease. Any portal-based product for wireless hotspots can help you out here.

My problem: It is possible with our current wireless network that a situation could arise where the IP address pool for a specific service location could be exhausted due to Windows clients acquiring an IP address without being authenticated. Thus, if we have a large event taking place in-market, the IP addresses would be assigned and reassigned out (on a one-hour lease) to each Windows client connected to the network, possibly quickly exhausting a small IP address pool if enough clients were simultaneously up and connected. Does anyone have a good suggestion on how to avoid this from happening (aside from over assigning and wasting IP addresses or ignoring the problem)? Thank you for your time MArla Azinger Frontier Communications

Many here know I have a rather significant interest in wireless networks. In other forums I'd compose a lengthy and thorough reply, but I think this topic is pretty far "off topic" for a list of mainly network operators who don't operate wireless networks. Perhaps the MLC could comment? -Tk
