Radiance Technologies Patents Boost Bandwidth Efficiency

By DE Editors

Radiance Technologies(Los Altos, CA) announced patents for data-transfer technologies overthe Internet or other IP-based networks. The patents--one forscheduling and executing data transfers and another for controllingdata transfer rates--focus on core components that make Radiance'sflagship TrueDelivery application unique as a vehicle for deliveringcontent in mission-critical environments.

According to a press release, the patents enable users of TrueDeliveryto achieve bandwidth efficiencies as high as 80 percent on a pipe, asopposed to a less than 25 percent efficiency achievable with competingtechnologies on the same pipe. For example, the Radiance file-transferalgorithm breaks files into "linear packages" that are sent asmultiple, parallel data transfers, rather than as a single, monolithicdata transfer typical of other methods.  The result is typically athree-to-one edge or higher in bandwidth efficiency. 

The second patent cites algorithms by which TrueDelivery manages dataflow on a network. Whereas conventional algorithms specify sending dataacross network nodes in a best-effort fashion, TrueDelivery providesnetworking intelligence for sharing of resources on network nodes andfor setting resource objectives such as deadlines for delivery of data,storage space, and minimizing the cost of delivering data. As a result,a TrueDelivery system can provide a guarantee of 100 percent contenttransfer capability. 

"These patent wins demonstrate Radiance's intent to protect itsleadership position in delivery mechanisms for mission-critical digitalcontent," said Tom Engdahl, President and CEO of Radiance.
