Netflow

Metric	Description	Values
Octet delta	Traffic difference (bytes) at the beginning and end of the specified period
Fragmented packets delta	Difference of IP packets divided into parts/fragments at the beginning and at the end of the specified period
RTT	Round-trip time is the time taken to send the signal plus the time it takes to confirm that the signal has been received. This round-trip time therefore consists of the time it takes to transmit a signal between two points within a single flow. All network activity within a source/destination socket (source IP:port /destination IP:port) is taken as a flow in DPI
Sorce AS	AS host number
Destination AS	Subscriber's AS number
Post nat source IPv4-address	An IP address converted from private to public by NAT to communicate with external devices and access the Internet
Post nat source port	A port converted by NAT from private to public for communicating with external devices and accessing the Internet
Vchannel/Bridge	Vchannel — vChannel number. Bridge — number of the bridge through which the traffic goes
Service class	Traffic classes cs0 — cs7. For more details see Traffic distribution by class for the tariff plan	0 — cs0 1 — cs1 … 7 — cs7
Reciever IP-interface index and Sender IP-interface index	Traffic direction	1 — to whom traffic is directed; 2 — where the traffic comes from. Example: The first option is outbound traffic; The second option is inbound traffic. :dpi:qoe:paramdescript:index.png
