Course Duration: 3 Days
Course Code: PDN083
Course Description:
This seminar covers all aspects of ATM technology concerned with building an ATM network in either a service provider of private backbone environment to function as a multi-service platform. It explores the objectives and mechanisms of ATM, especially its ability to provide quality of service and describes how these are used to carry voice data and video applications. A high quality workbook that contains fully documented text as well as a copy of all the slides accompanies the course. The intention is that the workbook should provide a useful reference volume for delegates long after they have attended the course.
Prerequisites:
This course assumes that delegates have had previous exposure to data networks and understand the basic principles of data communications. Delegates should ideally have some Hands On experience in a support environment, although this is not strictly required.
This course includes the following modules:
Basic Concepts
- What does an ATM network look like?
- How ATM is different from other packet switching technologies
- The basic principles of cell switching
- Connection identifiers and how they are used
- The advantages of the ATM approach in delivering quality of service
- Comparison of ATM with other QoS technologies
ATM Connections
- ATM connection characteristics
- The significance between permanent and on-demand connections
- Virtual channels and virtual paths
The ATM cell
- why they are there and when they are used
- The principle of point to multipoint connections
- What are Soft/smart PVCs and where are they used
Above and Below
