Re: Real world sflow vs netflow?

When a switch/router decides to sample a packet it records the ingress/egress interfaces and accumulates information about how it decided to forward the packet by examining its FIB tables. Each packet may take a different path, some may by switched at layer 2, others may be forwarded based on a local routing protocol like OSPF, and still others may be forwarded based on BGP.

OK, Well I guess I was thinking sFlow was primarily a switch oriented technology versus on a layer-3 peering router.
