The patent in question, which was filed in the US, is for a host-to-host adoptive routing protocol which detects internet congestion and determines the best ‘routing’ of data from a customer’s origin servers across the internet, to enable quick delivering all types of text and images.
Internet packet routing can be disrupted by a number of things, including hardware and line failures, configuration errors, incorrect routing policies and network congestion.
Host-to-host adoptive routine protocol systems, on the other hand, work with standard routing protocols to avoid routing paths where these problems exist.
In a separate lawsuit, which has yet to be heard, C&W has alleged that Akamai’s EdgeSuite and Akamaizer tools infringe its new patent relating to content delivery networks.
In a statement released yesterday, C&W characterised the latest lawsuit as “one aspect of what is expected to be a multi-year effort to protect [Cable and Wireless’]intellectual property.”
Akamai is reported to have rejected C&W’s allegations.
