Exporter
A device (in this case, the RDR formatter component in the SCE platform) with NetFlow services
enabled, responsible for exporting information using NetFlowV9 protocol.
NetFlow Collector
A device that receives records from one or more exporters. It processes the received export packet(s)
by parsing and storing the record information. Records can be optionally aggregated before being
stored on the hard disk.
Export Packet
A packet originating at the exporter, carrying the records of the exporter to the NetFlow collector.
Packet Header
The first part of an export packet. the packet header provides basic information about the packet such
as the NetFlow version, number of records contained within the packet, sequence numbering, and
the observation domain source ID.
FlowSet
A generic term for a collection of flow records that have a similar structure. In an export packet, one
or more flowsets follow the packet header. There are two different types of flowsets:
Template flowset Template FlowSet
–
Data flowset.
–
Template FlowSet
One or more template records that have been grouped together in an export packet
Template Record
Defines the structure and interpretation of fields in a flow data record.
Data FlowSet
One or more records, of the same type, that are grouped together in an export packet. Each record
is either a flow data record or an options data record previously defined by a template record or an
options template record.
Flow Data Record
A data record that contains values of the flow parameters corresponding to a template record.
