-->The LLTD protocol enables applications to quickly discover devices at the data-link layer, and it enables a central, graphical view of everything that is connected to the network. Any device that implements LLTD appears on the Network Map with a rich icon that represents the device, allowing users one-click access to the device’s Web user interface (UI).
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.

Specification link: Link Layer Topology Discovery Protocol Specification
Network Topology and QoS Extensions: LLTD
The specification for Link Layer Topology Discovery describes how the LLTD protocol operates over wired (802.3 Ethernet) and wireless (802.11) media. 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. Applications can dynamically adapt to changing network characteristics if devices support LLTD QoS Extensions.
Exploring the Network: Link Layer Topology Discovery
LLTD is a key Windows Rally technology. In every version of Windows Vista, LLTD is on and enabled by default. 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. Avalon hill game rules. When LLTD is invoked, it provides metadata about the device that contains static or state information, such as the MAC address, IPv4/IPv6 address, signal strength, and so on, as well as a scaleable icon that represents the industrial design or form factor of the device.
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 ability to know network topology is important for diagnosing and solving networking problems, and it is especially important for streaming content over a wireless connection. Providing a centralized Network Map ensures that a user-friendly view is easily available to show the overall network state and device health, to either the end user or a support assistant. LLTD is meaningful for device vendors who:
- Want to reduce support costs and product returns due to setup problems.
- Would like their products’ industrial design or form factor to appear to users in Windows Vista.
LLTD enables easy, one-click access to the device’s setup and management Web UI. The Windows Vista Network Map exposes the device UI as a right-click option, thereby providing easy access to the device, regardless of whether the customer installed a custom setup utility.
QoS Extensions: Prioritizing Audio/Video Streams to Devices
QoS refers to the mechanisms used to provide a desired level of network service to an application on IP-based networks. On a home network, A/V streaming traffic competes with other data and best-effort traffic. QoS support for A/V on home IP networks is advanced through new support in Windows Vista: qWAVE and QoS Extensions to LLTD.
qWAVE provides an API that allows applications to dynamically adapt to changing network conditions in real time. This technology enables A/V applications to provide a quality user experience, especially on wireless home networks. qWAVE provides new features that focus on streaming multimedia and real-time content over variable bandwidth networks, including:
- Auto-discovery of end-to-end QOS compatibility
- End-to-end bandwidth estimation of maximum link capacity (bottleneck bandwidth) and real-time available bandwidth
- Intelligent packet prioritization
- Congestion notification
- Flow shaping (rate throttling)
- Distributed admission control to enable multisource stream coexistence
qWAVE-enabled applications work together with devices that implement the LLTD QoS Extensions to greatly improve an end user’s experience of streaming video by safely and intelligently prioritizing traffic and reducing the impact of network-related transient issues.
I was recently reminded that Windows 8 is missing the Network Map feature that was introduced in Windows Vista and included in Windows 7. When I first discovered that the Network Map feature wasn't included in Windows 8, I developed an alternative technique that I have been happily using ever since. The other day I happened to field a question for a reader that reminded me of the missing Network Map feature and made me realize that I should write an article about the technique that I have been taking for granted all this time.The Network Map
The Network Map feature's visual representation of the network was its most recognizable characteristic. However, there were other more substantial benefits just under the surface. Of course, what I am referring to is that when you hovered your mouse pointer over any computer or network device shown in the map, you could instantly see the MAC and IP addresses assigned to that item. Being able to easily obtain this information for all the computers on a network can come in very handy in any number of troubleshooting situations.
When I first discovered that the Network Map feature was no longer a part of the operating system, I immediately went to the Network section of File Explorer hoping that Microsoft might have added a similar hover feature to the computer or network device icons that appear there. However, I quickly discovered that was not the case. Then, I stumbled onto the fact that when you switch the View setting of the Network from its default Tiles view to the Details view, you can add more column headings to the display. And, I found that MAC Address and IP Address were among the available column headings.
I also recently discovered a neat little Windows 8 app in the Windows Store called Lanscan that will scan you network and display the IP addresses assigned to every device on your network. While it doesn't show MAC addresses, it is still a very handy tool.
In this article, I'll show you how to take advantage of the Details view in the Network section of File Explorer. I'll also introduce you to the Lanscan app and show you how it works.
In Windows 7
Even though the focus of this article is on Windows 8 and the Network Map feature that is not available in this operating system version, it is worth taking a look at how it functions in Windows 7 for the sake of comparison.
When you access the Network and Sharing Center in Windows 7, you see a small basic map, or diagram, of your system on the network. Adjacent to that basic map you'll find a link titled See full map, as shown in Figure A.
Figure A
The Network and Sharing Center shows a basic map and provides you access to the full Network Map.
When you click See full map, you'll find a more detailed screen that shows how all the devices on your network are connected, as shown in Figure B. You can also hover your mouse pointer over any icon and find out the MAC and IP addresses assigned to that device.
Figure B
The Network Map feature does a reasonable job of creating a visual representation of your network.
To create this map, the Network Map feature uses a special network protocol called Link-Layer Topology Discovery (LLTD) that essentially queries every device on the network in order to determine how the network is organized. More specifically the LLTD protocol relies on two components in order to do the job.
To begin with, each device on the network uses the LLTD Responder component which allows it to be discovered by another computer running the Network Map feature. The computer on which you run the Network Map feature uses the LLTD Mapper I/O component to seek out and discover devices on your network and to create a diagram that shows how the devices on your network are connected. Unfortunately, this isn't a perfect system and not all devices are recognized. Those that aren't recognized get clumped together down at the bottom of the screen with this caption: The following discovered device(s) cannot be placed in the map. Click here to see all other devices.
Network and Sharing Center Windows 8
Now that you know how the Network Map feature worked in Windows 7, let's take a brief look at Windows 8's Network and Sharing Center for comparison. As you can see in Figure C, Windows 8 doesn't even include a basic map of your system on the network nor is there a See full map link. There's not even an icon next to the network name.
Figure C
Windows 8's Network and Sharing Center doesn't even include a basic map of your system on the network.
However, if you check out the Ethernet Properties as shown in Figure D, you'll find that the entire Link-Layer Topology Discovery protocol is present and functioning in Windows 8. Since the LLTD is functioning, we know that the network information it contains is available.
Figure D
The entire Link-Layer Topology Discovery protocol is present in Windows 8.
The Network Explorer
Let's now take a look at the Network section of File Explorer. As you can see in Figure E, the default List view shows just the name of the device and the context menu is devoid of a Properties command. As such, on the surface it appears as though the Network won't be of much assistance.
Figure E
In the default List view, only the device name is available.
However, if you change the View to Details and then access the Choose Details dialog box from the Current view tab, you can add more network based information to the display. As you can see in Figure F, I have selected the IP Address and MAC Address check boxes.
Figure F
The Choose Details dialog box will allow you to select network specific details including the IP Address and the MAC Address.
After clicking OK, you'll see the IP Address and MAC Address for each device on your network, as shown in Figure G. Keep in mind that that you may see IPv6 addresses for some or all of your devices, but if you click the Refresh button, you will eventually see the IPv4 addresses.
Figure G
Using the Details view, you can see the IP Address and MAC Address for each device on your network.
As you can see, there are two special cases in my example. The first one is that the computer named Asteroid is running Windows XP, which by default doesn't have the Link-Layer Topology Discovery protocol. (Note that you can download and install a version of the LLTD protocol for Windows XP.) The second special case is the computer on which you are working, which instead of its actual IP address, will show the Localhost IP Address.

The Lanscan app
As I mentioned, in addition to using the modified Network section of File Explorer to seek out IP addresses, I recently discovered a Free app on the Windows Store called Lanscan. Once you have installed Lanscan, you can launch it, specify start and end addresses, and click the Scan button. When you do, Lanscan will traverse your network and create a list showing every device's name, IP address, and port number, as shown in Figure H.
Figure H
The Lanscan app builds a detailed list of all the devices on your network.
If you don't wish to see all of the IP ports, you can go to the Services screen and select just those that you want to see.
