Overview
Voice, video, data and IPTV systems require skills to practically plan & dimension an IP network to handle a traffic mix of real and non real time. You will learn how to define a Quality of Service (QoS) strategy and then how to implement this practically using queuing, policing & traffic mapping with both DiffServ and RSVP. Multicast IP is also covered for support of real time services. Analytical and troubleshooting skills will be developed through the use of tools such as a network analyzer.
Course Objectives
You will be able to
- Explain triple & quad play services
- Use traffic engineering techniques
- Understand the QoS framework
- Deploy techniques for implementing QoS in IP networks
- Know how session border control works
- Implement DiffServ and RSVP
- Implement multicasting
- Perform capacity planning for IP networks
- Dimension an IP network for multiple services
- Calculate IP capacity using Erlangs
- Provision resources for packet traffic
- Provision resources for real-time voice & video traffic
Who can benefit
Network administrators, planners and engineers wishing to build on their knowledge of IP in a practical environment and enable QoS in their networks.
Pre requisite knowledge
It is essential that the participants have a good knowledge of the fundamentals of IP. The participant should have successfully completed the Certified IP Engineer (CIPE) practical and theory assessment.
