6.1 Managing Bandwidth – Introduction

When an IP WAN connects various sites in a Cisco Unified Communications network, bandwidth consumption at the IP WAN should be minimized. Several techniques can help conserve bandwidth on the IP WAN in a multisite deployment:

  • Reducing the required bandwidth of voice and video streams
  • Separating some voice streams (such as local media resources) from the IP WAN
  • Employing special features like multicast MOH from branch router flash (or the use of transcoders)

In this section, we describe all of these techniques and features, and their implementation.
