RE: Help needed - Cisco Netflow
Lee, The question would be do you want a self contained appliance or a piece of software? I have used Advent Network's Net Flow Analyzer. There are others out there but I've had some decent amount of luck with these guys and they have an "Enterprise" license that will many, many (thousands?) interfaces. For the traffic load and the number of flows/second I'm guessing you'll need a really high end Linux box with lots and lots of disk space. There are open source netflow collectors too you could deal with if cost is an issue or you have the talent on staff to maintain it.

The packet size for the NB-AMR traffic is fixed size 110 bytes. During the high load period, it can reaches 450Kpps on a STM-1 link. The router platform is Cisco 12000 series, can the router generate 100% netflow data with such traffic load? Also can someone suggest a carrier class netflow collector for mobile service provider environment. Thanks in advance.
