Summary:
This two-day seminar describes methods and techniques for
providing differentiated and guaranteed services within IP-based
enterprise networks. These techniques provide the bandwidth,
packet delay, packet loss, response time and availability guarantees
required for transmitting voice, data and video services over a
converged network. The seminar describes metrics used to define
quality of service (QoS), and tools such as Diffserv, Intserv and
MPLS, which can be used to guarantee QoS to customers. The
seminar will discuss the impact of encryption on QoS, and how to
provide QoS in multi-domain networks such as the Global
Information Grid (GIG). The seminar will include analytical models
which can be used to predict and compare performance for various
QoS mechanisms. The seminar is particularly useful for
organizations that are planning to transmit critical applications on
wireless and satellite networks, where bandwidth is constrained and
links are susceptible to packet loss.
Instructor:
Burt H. Liebowitz is Principal Network Engineer at the MITRE
Corporation, McLean, Virginia. He has more than 30 years experience in
computer networking. His current assignment at MITRE includes the
development of performance models of mission critical IP-based
networks. Prior to MITRE he was President of NetSat Express Inc., a
provider of Internet and Intranet services over satellite. Before that he
was Chief Technical Officer for Loral Orion responsible for
Internet-over-satellite access products. Mr. Liebowitz has authored two
books on distributed processing and numerous articles on computing and
communications systems. He has presented courses at the MITRE
Institute and has lectured extensively on computer networking. He holds
three patents for satellite-based data networking systems. Mr. Liebowitz
has I.E. and M.S. in Mathematics degrees from Rensselaer Polytechnic
Institute, and an MSEE from Polytechnic Institute of Brooklyn.

- Understand the differences between admission control
techniques used for voice and video transmissions
- Learn about products and techniques that can reduce
bandwidth demands in networks with constrained links
- Understand the impact of military Precedence and Preemption
requirements on QoS
- Understand the impact of mission importance on QoS
- Identify the issues involved in establishing QoS in
multi-provider environments
- Identify the issues involved in establishing QoS within mobile
networks
- Understand the role of network management and Service
Level Agreements (SLA) in supporting QoS requirements
- Introduce students to the use of simplified analytical models
to estimate call blocking probability, packet delays and
response time in converged networks
Course Outline:
