Installment 012 of The Custom Integrator Show is live. We continue our discussions on UPnP Technologies and the whole DLNA platform built into Windows 7. We actually spend much of this Podcast reviewing the ADDCEP architectural model we introduced in Installment 011 (http://thedigitallifestyle.com/cs/blogs/custom/archive/2009/06/16/the-custom-integrator-show-installment-011.aspx), so the text in that blog post covers the topics discussed in this Installment. We complete the ADDCEP layers by covering the Control, Eventing, and Presentation services, but leave out most of the examples because they are more applicable to the A/V features of the DLNA platform, which we will be discussing in more detail in our upcoming Installments.

However, I do want to include the diagrams we will be referencing in our next installment as we move into how UPnP Technologies apply to Internet Gateway Devices (IGDs). One physical IGD actually contains several services inside of it, each addressable and controllable individually. The following diagram shows that there technically can be multiple WAN connections in addition to multiple LAN connections within a single device, although most vendors only incorporate one of each. This also depicts a rather basic implementation. There are several other services that can be included in an IGD for handling features like Remote Access, Management, QoS, etc. You can see that, although there usually is a single check box within an IGD’s (commonly referred to as a broadband router’s) configuration and management user interface for enabling UPnP Technologies, there are several individual UPnP Services within the device as we start to peel away the onion. We will discuss how these pieces fit together and the protocols involved when communicating with them in Installment 013.

THE IGD’S UPnP SERVICES IN MORE DETAIL
The above diagram will be tough to describe in the Podcast, so please use it as a reference as we dive into the individual pieces for the next Installment. These services and how they are controlled and managed are key “ease of use factors” as we look at some of the new features included in Windows Home Server and Windows 7. As always, look for the Windows Logo on these devices to ensure the right “special sauce” is built in.
