NeTraMet V3.2 now available
                 ---------------------------

A new version of NeTraMet, the first implementation of the Internet
Accounting Architecture (outlined in RFC 1272, "Internet Accounting
Background") is now available.

This version uses libpcap to access packet headers.  This greatly
increases the range of operating systems on which the NeTraMet meter
can run; binary distribution files are available for Solaris, SunOS,
Irix and linux.  Libpcap also supports FDDI interfaces; this option is
implemented for NeTraMet, but not completely tested.  A short
description of NeTraMet and NeMaC appears at the bottom of this note.

There is a NeTraMet Users' mailing list (details below); any comments, 
suggestions, enquiries, etc will be very welcome.

 * To subscribe to the list send a message to majordomo@auckland.ac.nz
   with the body subscribe netramet your.address@domain

 * To send a message to the list, send it to netramet@auckland.ac.nz

If you are interested in network traffic metering/accounting/
management, why not join the Internet Accounting mailing list,

NeTraMet is an accounting meter which runs on a PC under DOS or a Unix
system.  It builds up packet and byte counts for traffic flows, which
are defined by their end-point addresses.  Addresses can be ethernet
addresses, protocol addresses (IP, DECnet, EtherTalk, IPX or CLNS) or
'transport' addresses (IP port numbers, etc), or any combination of
these.  The traffic flows to be observed are specified by a set of
rules, which are downloaded to NeTraMet by a 'manager' program.
Traffic flow data is collected via SNMP from NeTraMet by a 'collector'
program.

NeMaC, a combined manager and collector program, is supplied with
NeTraMet.  It downloads rules to meters, and collects data from them.
Although a meter may only have one manager, its data can be collected
by several collectors, which do not have to be synchronised.  NeMac
can manage and collect data from an arbitrary number of meters.

The format of NeMaC's collected flow data files is very general; the
contents of data lines in the file is completely specified by the
user.  ASN.1 opaque objects are used to retrieve flow data so as to
minimise the overheads in using SNMP for this purpose.

NeTraMet provides a valuable tool for analysing network traffic flows,
and should prove to be of interest to anyone interested in network
monitoring, capacity planning, performance measurement, etc.
