sFlow Collection
The sFlow standard describes a mechanism for capturing traffic data in switched or routed networks. It uses a sampling technology to collect statistics from the device and is applicable to high-speed networks. A sFlow agent is the implementation of the sampling mechanism on the hardware. The sFlow Collector is a central server which collects sFlow datagrams from agents and stores them for analysis. The sFlow agent uses two forms of operation: a statistical packet-based sampling of switched or routed packets, and time-based sampling of interface counters. The basis for the LiveNX implementation of a sFlow Collector is similar to the collection and parsing of NetFlow and J-Flow packets. The LiveNX sFlow Collector collects and parses sFlow export packets sent by a remote network device, and passes along the flow information to the LiveNX flow database.
