Reducing Latency and Jitter Using Multilink PPP Roadmap

First Published: May 2, 2005
Last Updated: March 21, 2011

This feature roadmap lists the Cisco IOS features related to Multilink PPP (for reducing latency and jitter) in the Cisco IOS Quality of Service Solutions Configuration Guide and maps them to the documents in which they appear. The roadmap is organized so that you can select your release train and see the features in that release. Find the feature name you are searching for and click on the URL in the "Where Documented" column to access the document containing that feature.

Feature and Release Support

Table 1 lists Multilink PPP feature support (as it relates to reducing latency and jitter) for the following Cisco IOS software release trains:

•Cisco IOS Releases 12.2T, 12.3, and 12.3T

•Cisco IOS Release 12.2S

Use Cisco Feature Navigator to find information about platform support and software image support. Cisco Feature Navigator enables you to determine which Cisco IOS and Catalyst OS software images support a specific software release, feature set, or platform.
