Windows Rally
I had to talk about Windows Rally, really
. I don’t have any clear opinion on this technology but I’ll try to give the main ideas around it.
Here is some Microsoft propaganda about it :
The Microsoft® Windows® Rally™ technologies provide device manufacturers with the best platform for creating effortless, secure and reliable connectivity between their devices and PCs, support for new connectivity scenarios, and richer experiences for their customers while reducing the cost and time of development.
Device manufacturers who take advantage of the Windows Rally technologies can reduce their development and support costs, while increasing their ability to innovate with devices that offer new user experiences in media networking, Internet communications, and device-to-PC and device-to-device data exchange.
Microsoft® Windows® Rally™ technologies provide device manufacturers with an architecture and toolset for improving the security, reliability, and usability of network-connected devices. Windows Rally technologies enable effortless setup and more secure and manageable connectivity to other devices and PCs.
Devices that incorporate Windows Rally technologies give users access to richer, more secure experiences. Windows Rally technologies enable easier integration of devices with the end user’s digital environment, while advancing control of network Quality of Service (QoS) and diagnostics.

Basically, Microsoft Rally is based on 4 protocols:
- LLTD : Link Layer Topology Discovery protocol : enables to quickly discover devices at the data-link layer
- Windows Connect Now : enables simple and secure configuration of wireless networks and provisioning of wireless hardware
- Devices Profile for Web Services : a set of Web Service specifications and constraints that define a core set of Web Services functionality
- Plug And Play Extensions (PnP-X): network-connected devices as discoverable as those that are connected directly to a computer over a bus such as Universal Serial Bus
This protocol stack is royalty-free… so I guess I’ll have a look at those as at least the LLTD looks interesting !
