Even if you don't currently have sFlow capable routers and switches, you can
still experiment with sFlow. InMon has a free software-based probe that will
monitor a switch/router using the mirror/SPAN port (see
http://www.inmon.com/sflowSoftwareProbe.htm ). There is also source code for
an sFlow agent (see http://www.inmon.com/sflow.htm ). The code compiles to
provide a host-based traffic monitor, but it can also be used to build your
own probe, or to add sFlow monitoring to existing packet forwarding
applications (such as routing, firewall etc.)
InMon also offers free evaluations of its commercial version of the sFlow
Probe. This version of the probe can monitor a number of Gigabit mirror/SPAN
ports at wire speed (see http://www.inmon.com/probes.htm ).

I had been thinking along the lines of traffic analysis applications I
mentioned in my previous message (
http://www.sflow.org/sflow-discussion/0004.html ). However, if you are
primarily interested in generating flow records, then there are fewer
options. In addition to the sFlow probe (see above), Netramet (
http://www2.auckland.ac.nz/net//NeTraMet/ ) and Coral Reef (
http://www.caida.org/tools/measurement/coralreef/ ) are applications that
provide flow record generation capabilities.
You didn't mention the type of network equipment you have. Depending on the
vendor and model, the switch/router may provide sFlow (see
http://www.sflow.org/equipment.htm ), LFAP (see http://www.nmops.org/ ) or
NetFlow (see http://www.inmon.com/netflowagents.htm ) data export.
