Latest Patents

Radu's latest patents include "Caching with selective multicasting in a publish-subscribe network" and "Method and apparatus for implementing query-response interactions in a publish-subscribe network." The first patent addresses packet routing via payload inspection at routers within a distributed network. It details how packets include subjects and attributes alongside routing information. The subjects correspond to specific content types for subscriptions, while the attributes encapsulate the data. Routers store filters that correspond to content subscriptions. Upon receiving a packet, a router inspects the payload section to retrieve attributes and apply them to the filters. If an attribute satisfies a filter, the packet is routed accordingly; otherwise, it is discarded. This method allows for distributed routing decisions among routers in the network core, with local caching of data.

The second patent outlines a method for implementing query-response interactions in a publish-subscribe network. It describes how an advertisement related to a data set and a query representing a logical expression are received. The advertisement is mapped to a corresponding subscription, while the query is mapped to a notification. These elements work together to facilitate the advertisement and query within the network.
