Systems and methods for many-to-one bi-directional auto-discovery

Abstract:

A method of many-to-one auto-discovery between modules includes: a source (sender) module sends the same source-ID on all its connected ports (many). The module may not know on which port the ID is sent. A sink (receiver) module is capable of receiving IDs on its port (one). The sink port identifies the association-ID (AID) of one end of the association (between sender and receiver). The association may be established based on each module discovering the sink AID of the sender in both directions (bi-directional). Both directions may be required for the source signal to get received on a respective sink. The source signal may be sent asynchronously in each direction.
