sFlow.org < http://www.sflow.org/> provides information about sFlow.
It's pretty easy to try sFlow. There are a number of vendors with sFlow
enabled switches and routers < http://www.sflow.org/products/network.php >
and applications for collecting and analyzing sFlow <
http://www.sflow.org/products/software.php >. There is also free sFlow agent
and decoder source code < http://www.sflow.org/developers/tools.php > that
will let you experiment with sFlow.
For basic backgroup information on sFlow take a look at the "About sFlow"
pages < http://www.sflow.org/about/ >.
You asked whether sFlow was a suitable replacement for NetFlow. There are a
number of technologies for monitoring traffic on networks, including: sFlow,
RMON and NetFlow. Each approach has very different characteristics. The
technology you choose will depend on your requirements. Some of the
strenghts of sFlow include:
* Layer 2 support: MAC addresses, vlans, priorities etc. Packets don't need
to be routed to be monitored.
* IPv6 support
* High performance: wire-speed 10Gigabit sFlow implementations already
exist.
* Low cost: available in all classes of equipment, including inexpensive
layer 2 switches.
* Scalable: all ports in the network can be monitored continuously from a
single point, presenting a network-wide view of traffic patterns.
* Multivendor: industry standard (sflow.org)
* Real-time: sFlow collector has central real-time view of traffic
throughout the network.
