Introduction

This Cisco Service Control for Managing Remote Cable MSO Links Solution Guide describes the use of a Cisco Service Control solution in a cable environment to optimize traffic on remote links. It describes the setup of a solution that uses the Virtual Link Manager (VLM) to enable traffic optimization of remote links, and the monitoring of that solution after deployment.

This guide assumes a basic familiarity with the concept of the Cisco Service Control solution, the Cisco Service Control Engine (SCE) platforms, and related components.
