SYNOPSIS

Input

Stream of packets.

Output

  1. A record set which maps client IP address to the calculated bandwidth. This set provides a mapping which can be used to join the bandwidth information along with a different record stream.

  2. Record stream of client addresses and their associated bandwidth. Whenever a client has been inactive for 30 seconds, the measured bandwidth is emitted in this stream.

The bandwidth unit is kilobytes/sec.

DESCRIPTION

This tool calculates individual client bandwidth based on the timing of the packets.

Note

A negative bandwidth value is returned in the following cases:

  • The client IP address was not present in the input (returns bandwidth value -1).

  • The Netlogger has not yet been able to calculate a bandwidth value due to insufficient traffic exchange between client and server (returns bandwidth value -2).

OPTIONS

None.
