Kontiki enhances content delivery network

Kontiki Inc. this week announced version 3.0 of its Delivery Management System (DMS) featuring a new plug-in for secure content delivery and the ability to target content at specific people or groups in an organization. The company is also offering services to help customers deploy software and create video content.

DMS is a software-based content delivery network that uses Windows PCs and origin servers to deliver content, usually large video files, more efficiently. It combines the file-sharing technology of peer-to-peer networks such as Kazaa with the functionality of a typical content delivery network by placing content as close to intended users as possible. After a user requests a file, it is stored on their machine for a set period of time, where other local users can download it. A central Grid Server directs client requests to the closest copies of the content, which can be downloaded from multiple locations simultaneously.

Like with any content management system, this limits strain on a central download server for popular content and helps reduce bandwidth usage charges. Unlike services such as Kazaa, the owner of the DMS controls what content is available on the network. Users cannot add files at will. Though any content type can be delivered with DMS, Kontiki is targeting customers with large video files used in corporate communications and training.

Similar offerings are available from Jibe and Blue Falcon Networks Inc.

For customers concerned with the integrity of the content stored in the DMS, version 3.0 includes a new security plug-in that offers virus checking and digital rights management (DRM) capabilities. The addition of DRM "prevents content from accidentally or intentionally getting out," says Chris Saito, vice president of marketing for Sunnyvale, Calif.-based Kontiki.

A new XML Web services interface allows customers to integrate with existing corporate directories, allowing content stored in the DMS to be accessed only by specific groups or users. Content meant for the sales group will only be viewable by the sales group, for instance.

Also in version 3.0, network administrators will have more control about how the content is delivered. Network managers can limit where content is downloaded from to save a PC in Boston from trying to download a massive file from a PC in Taiwan, Saito says. For internal corporate deployments, administrators can limit the clients to downloading only company data, not from other Kontiki-based networks outside the company.

As part of the 3.0 release, Saito says Kontiki is formalizing its professional services group designed to help customers build a content delivery network and create content for it. The Business Media Services include a service for helping set up in-house studios and producing video content for customers.

DMS 3.0 starts at around US$87 per user with a professional license plus a 22 percent maintenance contract.
