Harness the Power of Multicast

Multicast has been part of the IT toolkit for nearly three decades. Surprisingly, it's not deeply understood even in most IT circles. This is ok, when multicast is used for low-bandwidth applications. However, when using multicast to distribute live audio and video bandwidth requirements go way up, and it becomes critical to configure your network to properly handle this traffic. In this course we will explain the difference between multiciast, unicast, and broadcast traffic, and provide an understanding of the appropriate use cases for each. We will then explain why high-bandwidth multicast leaves no room for error, the way low-bandwidth multicast does. We will talk through some of the techniques for properly implementing multicast across multiple switches, with specific examples from graphical user interface (GUI) and command line interface (CLI) from several major switch manufacturers. Time permitting, we will talk about how multicast implementations do involve some proprietary protocols (per switch brand), and look to a future where unification in approach is possible, simplifying the implementer's live greatly.
Learning Objectives
  • Identify use cases where it makes sense to use multicast, rather than unicast or broadcast
  • Understand the complexities of managing multicast for high-bandwidth applications (such as audio and video streaming)
  • Learn strategies and techniques for implementing high-bandwidth multicast across multi-switch networks.
