Celix Publish Subscribe Codebase Intellectual Property (IP) Clearance Status


A distributed service oriented implementation of the publish subscribe pattern. The design depends on 3 modules. A module for discovery, another module for serialization and transport and lastly a topology manager module which control the other modules. Multiple implementation can of the modules can be used to offer different technologies (e.g discovery using etcd or mdns). This donation contains: A PubSub Topology Manager implementation, A PubSub discovery implementation using etcd, A PubSub transport/serialization implementation using UDP multicast / JSON and an alternative PubSub transport/serialization implementation using ZeroMq / JSON.
