Time period over which all data are aggregated into flows (for each set of client, server and application). The Aggregation Period is defined for an aggregation level as time interval over which all flows are aggregated in the database on their IP src/dst, Zone src/dst and Application. Individual flows within the aggregated data cannot be viewed se [..]

Group of logical or business-related flow to emphasize valuable perspective; an Application is identified with a name and a color, and defined by a set of Signatures or a set of Port Ranges (at least one non-empty set of either), a set of client and server zones. A conversation is attributed to an application with the following rule: (PORT_RANGE1 O [..]

NC stands for Non-Classified. An NC Application is a special application that will match conversations that match no other configured application.

Port or range of ports. It applies to both ‘TCP’ and ‘UDP’ when not used in conjunction with an IP protocol.

Remote probe that listens and analyzes the network traffic to produce statistics that the datastore will fetch and insert into the central database.

Time taken by the exchange of the 3-way TCP handshake. CT is defined as the duration of the three-way handshake (SYN, SYN/ACK, ACK) of a TCP session.

Regroups network exchanges between two network addresses for one application during the observation period. A conversation is defined as a group of flows between a client and a server over an observation period.

Time spent by the client or the server to send data. DTT server is defined as the time between the first data packet (with ACK flag and a non-null payload) from the server and the last packet considered as part of the same answer. DTT client is the symmetric metric in opposite direction. Packets are considered part of the same answer if the packets [..]

Central database and Web GUI of PerformanceVision. The datastore can also host a local capture, and usually collects statistics from remote captures.

Number of sessions established minus those closed. Delta Session is a metric defined as the difference of the number of opened sessions to the number of closed ones. A negative value means that more sessions were closed than opened.
