TOKYO, JAPAN, September 19, 2002 --- NTT DoCoMo, Inc. announced today that the company, working jointly with Hewlett-Packard Company and Hewlett-Packard Japan, has developed world's first technologies for a highly advanced multimedia content delivery network suited specifically to third-generation (3G) and future mobile communications services.
The Mobile Streaming Media Content Delivery Network (MSM-CDN) is the result of the three companies' joint research into future mobile communications systems, for which they signed a memorandum of understanding in December 2000.
It is expected that 3G and future mobile communications services will be used for the delivery of extremely large volumes of content, such as video, via the internet. Technologies for large-scale content delivery are being developed, but so far they have not resolved key problems peculiar to the mobile environment, such as following the movements of wireless users and servers being overloaded as millions of customers access them simultaneously.
MSM-CDN represents the first set of large-scale content-delivery technologies designed exclusively for 3G and future mobile communications services. A key feature of MSM-CDN is its delivery servers, which are optimized for effectively delivering content from the internet, especially streamed content, via mobile networks.
In addition, management servers monitor network traffic and delivery-server loads in the MSM-CDN to dynamically control and modify how content is delivered to mobile users, resulting in a highly efficient and reliable method of delivery. With dynamic selection of the best delivery server for each task, network load remains evenly balanced even in times of peak use. Moreover, the management servers enable switching from one delivery server to another for the uninterrupted transfer of content as mobile users move around.
Another major advantage of the MSM-CDN is that it will enable the servers of content-providers to reliably host millions of mobile customers simultaneously for the downloading of large-scale content without delay and content quality degradation.
