Although the final version won't be ready to ship to developers until the summer, Palm wants developers to start making sure their programs will work on version 5 of the Palm OS.
With the OS upgrade, Palm is moving to a new class of processors. Emulation software is designed to allow older programs to work in the new OS, but Palm estimates that only about 80 percent of programs will be compatible--the remainder will be shut out because of nonstandard programming techniques used by developers to make their programs run better on Palm's current chip, the relatively slow Dragonball processor from Motorola.
Although Palm has been the market leader, analysts have been eagerly awaiting the move to a more modern chip architecture, as well as other features that Palm has promised for OS 5, including improved security, virtual private networking software and support for 802.11b wireless networks.
"Our philosophy is to keep the OS tight and reliable," said Steve Sakoman, PalmSource chief product officer.
At the PalmSource Conference, which runs Feb. 5-8, developers will receive a Palm OS 5 Compatibility CD that provides a preliminary version of Palm OS 5, tools, and 20 compatible applications. Tools include the Palm OS 5 Simulator, Palm Universal Debugger, Constructor and PalmRez, Conduit Development Kit for Microsoft Visual Studio .NET / Mac OS X and Third-party developer tools. Members of the Palm OS
Developer Program will be able to download the following tools from the Palm
OS website ( http://www.palmos.com ).
Super-Net has overcome these problems by implementing Nortel's Quality of Service on Ethernet switching.
QoS allocates priorities to some streams of data so critical applications get higher priority during periods of network congestion. To test the difference in performance, CeNTIE loaded Super-Net lightly at 9Gbps -- roughly the same as Sydney's phone system traffic at peak-hour.
Then, without using QoS, it put the last 1Gbps in, so the network was totally congested.
"First the video freezes, the haptics disappear, then the remote end starts wobbling and jerking and you're wondering what the hell's happening," Dr Economou said.
"Then we increase the QoS for the video stream and after about 10 seconds the video resyncs and bang, you've got video. But the haptics link is still broken so we increase the priority on the haptics traffic and bang, it's working again.
"The critical applications have a high priority so they're getting through no matter what."
The 10Gbps Ethernet will become very important in the next few years.
It's competing head-on with Sonet, the current standard in metropolitan area networks, Dr Economou said.
