General Description

SSG supports exporting statistics for the following main data streams:

NetFlow by protocols — protocol-specific information. Protocol numbers are transmitted according to the reference guide,

NetFlow by directions — information on Autonomous System (AS) numbers. AS numbers are transmitted according to the reference guide,

NetFlow for billing (RADIUS accounting) — information on the amount of transmitted data per subscriber. This stream is transmitted to fastPCRF and converted into RADIUS accounting,

Full NetFlow — complete (non-sampled) data for each subscriber with additional fields for QoE (RTT, retransmissions) and NAT flow. Additional fields are available only in the IPFIX format (NetFlow v10).

Full NetFlow can be exported in one of the following formats:

IPFIX (NetFlow v10),

NetFlow v5.

For receiving, processing, and storing NetFlow, we recommend using the QoE Store statistical collection software and the DPIUI2 graphical interface.

Additional data streams for IPFIX export:

ClickStream — user web requests, used in QoE,

SIP,

FTP,

Messenger metadata (XMPP),

Email protocol metadata (POP, IMAP, SMTP),

Raw unparsed metadata.
