1.2.16 s-Flow Agent
The APS Series switches support s-Flow network monitoring. sFlow is a sampling technology that
meets the key requirements for a network traffic monitoring solution:
 sFlow provides a network-wide view of usage and active routes. It is a scalable technique for
measuring network traffic, collecting, storing, and analyzing traffic data. This enables tens of
thousands of interfaces to be monitored from a single location.
 sFlow is scalable, enabling it to monitor links of speeds up to 10Gb/s and beyond without
impacting the performance of core internet routers and switches, and without adding
significant network load.
 sFlow is a low cost solution. It has been implemented on a wide range of devices, from
simple L2 workgroup switches to high-end core routers, without requiring additional
memory and CPU.
 sFlow is an industry standard with a growing number of vendors delivering products with
sFlow support.
sFlow is a multi-vendor sampling technology embedded within switches and routers. It provides the
ability to continuously monitor application level traffic flows at wire speed on all interfaces
simultaneously.
The sFlow Agent is a software process that runs as part of the network management software within
a device. It combines interface counters and flow samples into sFlow datagrAPS that are sent across
the network to an sFlow Collector. Packet sampling is typically performed by the switching/routing
ASICs, providing wire-speed performance. The state of the forwarding/routing table entries
associated with each sampled packet is also recorded.
The sFlow Agent does very little processing. It simply packages data into sFlow DatagrAPS that are
immediately sent on the network. Immediate forwarding of data minimizes memory and CPU
requirements associated with the sFlow Agent.
