Traffic statistic collector
I'm working on a proposal to run some OCx circuits southbound to connect to the NAPs and IX's of the world. I need to calculate how much traffic I'm sending to each member and to each members' customers. I'm using cflowd to gather info from the routers but I'm wondering if anyone knows of a script/proggy/hack that can take an AS or a series of netblocks, run them against the multiple cflowd data files, parse it out and spit out a MB/sec figure of some sort.
A little script I wrote up that uses arts/cflowd/rrdtool to output to an HTML page, I'm very open to comments since its still in beta stage. http://noc.vdi.net/lusers/missnglnk/aslist/ On Wed, 22 Nov 2000, Jason Lixfeld wrote:

Lance Tatman and I will be presenting a paper on that subject at ISMA in a couple of weeks. Abstract at http://www.caida.org/outreach/isma/0012/ISMAagenda.xml#alex -Bill

Take a look at Dave Plonka's FlowScan: http://net.doit.wisc.edu/~plonka/FlowScan/ ________________________________________________________________________ Jay Ford, Network Engineering Group, Information Technology Services University of Iowa, Iowa City, IA 52242 email: jay-ford@uiowa.edu, phone: 319-335-5555, fax: 319-335-5505
I've tried flowd before and tried it again just now, running aggregation on as and charting it I see far less traffic being reported in cflowd than i see going across the interface, why might that be? also doesnt the system only report the next hop as so how do you determine how much you send to a particluar AS without listing all prefixes? I also get a lot of traffic coming in from my AS even though its an edge router interface, why might that be? Hmm Steve -- Stephen J.
