                 NeTraMet V2.1 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.

Many improvements have been made since the initial release in October
93, including:
   * Subroutines in rule tables, which makes it much easier to write
       rules to handle large numbers of networks.
   * Labels for rules and actions; no need to keep track of rule and
       action numbers by hand.
   * CLNS protocol now understood by NeTraMet.
   * Packets for protocols not understood by NeTraMet can be counted
       as PeerType 'Other'.
   * Ethernet II and SNAP encapsulations for IPX now recognised (as
       well as 'Raw 802.2').
   * Make files for Ultrix added.  NeMaC has been ported to Ultrix.

A short description of NeTraMet and NeMaC appears at the bottom of
this note.

User comments and suggestions will be very welcome: please post these
to the Internet Accounting mailing list, accounting-wg@wugate.wustl.edu.
We are planning a BOF for the newly revived Accounting Working Group
in the Operations Area (rather than Network Management) at the Seattle
IETF meeting in March 94.  To join the mailing list, send a request to
accounting-ml-request@wugate.wustl.edu.


NeTraMet is free software, and can be obtained by anonymous FTP from
the following sites:

   ccu1.auckland.ac.nz:  directory iawg/NeTraMet
      at any time between 0700 and 2000 GMT (traffic charges to New
      Zealand - which we pay - are cheaper between 8 pm and 9 am).

   ftp.delmarva.com:     directory pub/nms

   ftp.funet.fi:	 directory /pub/networking/management/NeTraMet

   ftp.EU.net (Amsterdam):  directory network/NeTraMet

The NeTraMet distribution files are as follows:

   Release.note		This file.

   NeTraMet.man.ps.gz	Users' manual only, in Postscript,
			   compressed with gzip.

   NeTraMet.tar.gz	Full distibution file, including NeTraMet.man.ps,
			   source and Make files for SunOS and Irix,
			   executable files for PC.  Compressed with gzip.

   NeTraMet.zip		Full PC source and Make files.  Archived
			   with pkzip; use pkunzip -d to unpack.

	
NeTraMet is an accounting meter which runs on a PC under DOS or a
SunOS 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 or IPX)
or 'detail' 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.  You are invited to
try it on your network!
