A thin thought: Smart Edges

September 17, 2005 06:01 AM

Topics: Technology

A totally non-actionable, useless, pie-in-the-sky thought.

Old fashioned desk phones are a bit like thin-client web terminals. A limited set of UI functions are communicated to a central, smart server. Management costs are minimised as a result.

The stupid network wants to invert all of this, and make the edges smart. When the telephony application is in a state of rapid flux, replacing a $100 device with a new, smarter $100 device is much less intimidating than risking the upgrade of a $10,000 PBX in the hope you’ve picked the right feature set. We’ve taken to using $1000 laptop PCs as telephones to get the functions we desire, because they’re more adaptable, and the change can be done with free or cheap software upgrades.

But there’s that little niggling issue of manageability of heterogenous distributed network devices. So I just wonder … could the idea of a “thin client” smartphone be feasible? Say you want a desk telephony device that can display Skype buddy presence, for example. Is the device itself the best place to put the Skype-specific application logic? Or is a device with a few softkeys, and a stripped-down web browser or Flash-type interface a better bet, interfacing to a server of some kind out there in the cloud?

There’s an unresolveable tension here. The stupid network is adaptable to change, and small incremental change at the edge is quicker than large change in the core; but change costs money, and co-ordinated change managed centrally can reap economies of scale. So as the level of uncertainty drops about what customers want out of Voice 2.0 over the next 5 or 10 years, expect to see the architecture shift accordingly.

Have a look here, there are folks out there developing some apps along these lines:

At least beginning to push more intelligence to the endpoint.

Definition (This post): Device; the last hardware in the chain of device’s/hardware/apparatus between Skypers. The thing you wear, hold in your hand and speak at, listen to, look at.
”Is the device itself the best place to put the Skype-specific application logic? Or is a device with a few soft keys, and a stripped-down web browser or Flash-type interface a better bet, interfacing to a server of some kind out there in the cloud?”

Now most of us are using a very or thin client, having some smartness in the PC and the rest delivered by the user ;) interacting with the PC.
The smartness is on the move, it is moving to HW housing embedded Skype and some form of remote configuration interfaces and the Device connected to that.
The USB Cordless DUALphone is a first step in this direction, making basic Skype options available from a DECT handset, but keeping Skype and the internet connection work in the PC.
The next step available might be like the LAN Cordless DUALphone with embedded Skype, more than basic Skype options from the HS and web configuration accessible from the internet or the LAN. Further I could see the base moving into the HS, but wouldn’t this also be an option when choose your next mobil-phone/PDA?
I expect the network will remain stupid, add-on services will be at the edge(s) and/or server centric as fits best like now with ex. VM and CF.
About HW will it continue the trend developing into multipurpose devices or singular ones or both?
