                ===================================

                              HARP 3

What is this stuff?
-------------------
The Advanced Networking Group (ANG) at the Minnesota Supercomputer Center,
Inc. (MSCI), as part of its work on the MAGIC Gigabit Testbed, developed
the Host ATM Research Platform (HARP) software, which allows IP hosts to
communicate over ATM networks using standard protocols.  It is intended to
be a high-quality platform for IP/ATM research.

HARP provides a way for IP hosts to connect to ATM networks.  It supports
standard methods of communication using IP over ATM.  A host's standard IP
software sends and receives datagrams via a HARP ATM interface.  HARP provides
functionality similar to (and typically replaces) vendor-provided ATM device
driver software.

HARP includes full source code, making it possible for researchers to
experiment with different approaches to running IP over ATM.  HARP is
self-contained; it requires no other licenses or commercial software packages.

HARP implements support for the IETF Classical IP model for using IP over ATM
networks, including:

   o IETF ATMARP address resolution client
   o IETF ATMARP address resolution server
   o IETF SCSP/ATMARP server
   o UNI 3.1 and 3.0 signalling protocols
   o Fore Systems's SPANS signalling protocol

        - Internet Draft draft-ietf-ion-scsp-atmarp-00.txt,
                "A Distributed ATMARP Service Using SCSP"

   o ATM Sockets interface
        - The file atm-sockets.txt contains further information

What's not supported
--------------------
The following major features of the above list are not currently supported:

        o UNI point-to-multipoint support
        o Driver support for Traffic Control/Quality of Service
        o SPANS multicast and MPP support
        o SPANS signalling using Efficient adapters

This software was developed under the sponsorship of the Defense Advanced
Research Projects Agency (DARPA).

 KERNEL CHANGES:
 
+o The Host ATM Research Platform ("HARP") software by Network
+  Computing Services, Inc. have been intergrated.
+  See /usr/src/share/examples/atm for more info.
+
+o The code responsible for maintaining time of day have been
+  rewritten.  New features are:  true support for nanoseconds in
+  both kernel and userland, continuous rather than stepwise adjustment
+  by NTPD, support for synchronizing to high precision external time 
+  signals.
+
+o Support for the PPS API described in draft-mogul-pps-api-02.txt for
+  TTL rising edge inputs via the parallel printer port.

+
 o The code from 4.4BSD-Lite2 has been (finally) merged.
 
 o The SMP (Symmetric MultiProcessing) branch has been merged.
