export protocols that aim at aggregating packets into flows. After that, flow records are sent to a collection point for storage and analysis. sFlow, however, has no notion of flows or packet aggregation at all. sFlow allows for exporting packet data chunks and interface counters, which are non-typical features of flow export protocols. Note however that (recent) IPFIX developments provide a means for exporting SNMP MIB variables and packet data chunks. While flow export can be performed with 1:1 sampling (i.e., considering every packet), this is typically not possible with sFlow, as it was not designed to do so. Sampling forms an integral part of sFlow, aiming to provide scalability for network-wide monitoring.
