ATM ABR Service Traffic Management Conformance Test
Tool:
This software kit is intended to provide a tool for ATM product developers and ATM test equipment
designers who need to construct test facilities for standard conformance testing of ABR
service rate control implementations. The protocol that is the target of this effort is provided in
the Available Bit Rate (ABR) rate control scheme specified in section 5.10 of the ATM Forum
Traffic Management (TM) Specification V4.0. This implementation tool provides the user with an
environment for executing all of the conformance test cases proposed by NIST to the ATM Forum for
ABR rate control (ATM Forum/97-0034).

- ATM/HFC
Simulator:
The provides a means for researchers and network planners to analyze
the behavior of ATM networks and/or HFC networks without the expense of building a real network. The
simulator is intended to be a planning tool for network operators and a protocol analysis tool for
researchers. For ATM networks, the simulator implements the AAL, ATM, and physical layers; for
Hybrid Fiber-coax networks, the simulator implements IEEE 802.14 and Society of Cable TV Engineering
(SCTE) Cable TV modem protocols. The simulator includes simulated applications using TCP/IP or
native ATM interfaces, and it contains a rich set of traffic models, including self-similar traffic
and MPEG-2 compressed video streams.

ATM Network Routing Protocol (PNNI) Performance
Simulator:
The PNNI Simulator allows researchers and network operators to
simulate the operations of the ATM network routing protocol in order to predict the performance of a
given network topology, to compare the performance of various configurations, and to study the
scalability of the ATM Forum PNNI protocol. Several performance measurement metrics are
provided.

ATM PNNI Protocol Interoperability Test
Tool:
The PNNI IOP tool was developed to assist software developers, test equipment vendors, and network
administrators to implement or perform tests for the ATM network routing protocol or ATM Forum PNNI
Specification V.1, based on the ATM Forum's Interoperability Test Suite for PNNI.

GMPLS Lightwave Agile Switching Simulator
- GLASS:
The GMPLS Lightwave Agile Switching Simulator (GLASS) is a simulation framework, developed by the
Advanced Network Technologies Division at the National Institute of Standards and Technology.
This simulation framework allows the modeling and performance evaluation of protocols (routing,
restoration, and signaling), algorithms, and traffic engineering for optical Internet. Designed as
an extension to the Scalable Simulation Framework Network (SSFNet), GLASS provides the user with a
high degree of link and optical layer details. The simulator provides Internet routers with MPLS
label switching, optical switches with lightwave switching, and optical switches with add/drop
capabilities. For each of these network nodes, the user can designate the protocols to be used,
either from the protocol library included in the distribution, or from the user’s own
implementation.

IPsec-WIT:
IPsec-WIT is an interoperability test system built around the
Cerberus IPsec prototype and commonly available WWW
technology. IPsec-WIT allows implementers and system integrators to remotely
control and execute series of interoperability tests with the Cerberus reference
implementation. Test case selection, configuration, execution and
results analysis are all controlled remotely using a WWW browser. This novel
use of WWW technology to control the test system allows IPsec-WIT to provide remote
interoperability testing services anytime and anywhere without requiring any
distribution of test system software, relocation of the systems under test, or
coordination of access to the reference implementation or tester.

ISPI:
ISPI is an interactive, integrated tool for measuring the performance of quality of service (QoS)
sensitive data streams while conducting experiments with emerging Internet resource reservation
protocols and real-time network services. ISPI is capable of supporting stream selection based upon
session directory protocols (i.e., SD, SDR), monitoring the performance of data streams that use the
Real Time Transport Protocol (RTP) and allowing proxy interaction with routers supporting the
Resource Reservation Protocol (RSVP).

NIST Net:
The NIST Network Emulation Tool NIST Net is a general-purpose tool for emulating performance
dynamics in IP networks. The tool is designed to allow controlled, reproducible experiments with
network performance sensitive and adaptive applications (e.g., voice over IP) and control protocols
in a simple laboratory setting. By operating at the IP level, NIST Net can emulate the critical
end-to-end performance characteristics imposed by various wide area network situations (e.g.,
congestion loss) or by various underlying subnetwork technologies (e.g., asymmetric bandwidth
situations involving xDSL and cable modems).

NIST-SIP is a signaling stack and message parser for the SIP (Session Initiation Protocol).
SIP is a telephony signaling protocol for IP Telephony. The distribution contains the following components:
A public domain extensible, modular JAVA based message parser for SIP A simple stack with authentication on support.
An implementation of the JAIN-SIP 1.0 interfaces on the basis of the NIST-SIP parser and stack. An XML based
call flow scripting tool for quick generation of call flows. A test proxy with an XML interface for service creation
that allows you to invoke test scripts from the proxy. A trace viewer tool for visualization of message traces that pass
through the stack.

NIST Cerberus IPsec Reference Prototype:
Cerberus is a leading edge prototype and reference implementation of emerging network layer Internet
security (i.e., IPsec) technologies. Implemented as a kernel module for the Linux operating
system, the Cerberus prototype provides complete support for IPsec authentication and encryption
services in both tunnel (i.e., firewall) and transport (i.e., host) mode.

NIST Switch:
NIST Switch is a rapid prototype platform for research in Multi-protocol Label Switching (MPLS), and QoS
routing. The NIST Switch platform implements MPLS forwarding and extensions tResourcesrouce
Reservation Protocol (RSVP) to support label distribution functions. Intitial release planned in
Q299.

- Seamless and Secure Mobility (802.16)
A simulation platform based on NS-2 is being developed
in order to leverage publicly available modules for
several wireless and wired technologies. IEEE 802.3
(Ethernet), IEEE 802.11b (WLAN), IEEE 802.15.1 (Bluetooth),
and UMTS have been developed for various releases of NS-2,
but have not been integrated to run jointly in a single
simulation environment. By integrating various
modules into a single platform, we make it possible to
simulate heterogeneous environments that incorporate a
variety of access network technologies.
