Digital Envoy Introduces Topology-Based Routing Technology
March 1, 2002 -- (WEB HOST INDUSTRY REVIEW) -- Digital Envoy (digitalenvoy.net) has announced the
availability of its RealPath intelligent routing technology allowing instant
Internet traffic management decisions to be made for global load balancing
or content distribution network applications, based on the analysis of
network topology and city-level geographic location.

RealPath, which is covered in seven separate patent filings, was
specifically designed for incorporation into content networking switches and
appliances to enable quickest-path routing decisions based on topology, as
well as to allow for content targeting and restriction based on the
geographic location of an Internet user.
RealPath allows enterprises to increase network performance and enhance
traffic management while optimizing bandwidth and decreasing processing
costs, the company says. With real-time measurement and analysis, routing
decisions can be made up to 500 times faster. Current infrastructure
technologies usually make decisions based on fewest-hop analysis and probing
techniques, whereas RealPath's topological view enables companies to more
effectively route and balance Web traffic with real-time decisions, as well
as serve and restrict content.
According to Rob Batchelder, research director with Gartner Group,
geographic traffic management is pushing the networking technology envelope
because it brings a new dimension to how content is individualized and
delivered.
"Ideally, the optimum approach to content delivery is to analyze the
characteristics of the network from the core to the edge and dynamically
alter not only how, but what content is delivered. The more refined that
analysis is, the more efficient and personalized that delivery can be," said
Batchelder. "Increasing the 'IQ' of a network, not only injects new levels
of relevance to content, but enables better routing, storage, placement and,
ultimately, end-user experience."
Companies including Digital Island, AOL Time Warner, Williams
Communications, Siemens and Coyote Point are already using RealPath in
infrastructure applications including global load balancing and traffic
management, content distribution and intelligent caching, and content
localization , which allows enterprises to automatically serve language- and
currency-specific content and products.
In addition, Digital Envoy's geo-location technology is featured in
Speedera's SpeedSuite offering.
