Lltd in windows

LLTD provides the added benefit of enabling quality media streaming experiences, even on networks with limited bandwidth. Devices that provide audio or video playback or that are bandwidth sensitive can implement the QoS Extension portions of the protocol to ensure that they receive prioritized streams and that changes in available bandwidth have little or no impact on the user experience.

As the protocol name suggests, LLTD enables device discovery via the data-link layer Layer 2 and determines the topology of a network. In addition, LLTD provides QoS Extensions that enable stream prioritization and quality media streaming experiences even on networks with limited and changing bandwidth.

Devices can also implement LLTD—and those that do so can report rich configuration information about themselves that appears in the various network map views available in Windows Vista, regardless of any IP configuration issues on the network. In addition, the Windows Vista Network Map uses LLTD to determine connectivity information and media type wired or wireless , so that the map is topologically accurate.

The tool provides an excellent means to view either ad hoc or infrastructure network elements. Windows Vista and Windows 7 provide the related elements by default. An overview of the functionality is available through WindowsSeven Forums.

While enabling the technology appears straightforward, there are a number of settings or configuration issues that can prevent the use of LLTD. While the WindowsSeven Forum provides an overview for enabling LLTD, it does not address some of the issues that can prevent the feature. The following list offers additional considerations when attempting to enable or troubleshoot the ability to draw a full network map.

There is a hotfix you will need to request from Microsoft. Your network connection needs to be identified as a recognized network profile.

An overview of creating and modifying network profiles is available for Windows Vista and Windows 7. Create or modify network profiles. This most commonly occurs when a device contains both a wired and wireless NIC.
