ATI's Quality of Service in IP-based Mission Critical Networks course


Share |

Summary:

    Technical Training Short On Site Course Quote

    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.

    Who Should Attend:

    Technical staff involved with the use of Internet technology in mission-critical networks, with strong requirements for quality of service. Basic knowledge of IP-based packet switched networks required.

    Course Objectives:

    • Understand the performance metrics used to define QoS in mission critical networks
    • Learn how performance metrics differ for elastic and inelastic applications
    • Learn how routers process and drop packets and how this affects QoS
    • Learn how RSVP, MPLS, DiffServ are used to provide QoS
    • 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:

    1. Introduction and Purpose including a definition of QoS
    2. A Quick Review of Internet Protocols how these protocols affect QoS
    3. Quality of Service Issues for IP-based Applications differences between voice, video and data services
    4. Provision of Differentiated and Guaranteed Services: Data and Control Planes admission control, packet marking and forwarding, IntServ, DiffServ, MPLS
