Abstract: One aspect relates to a communication protocol for communicating between one or more entities, such as devices, hosts or any other system capable of communicating over a network. Another aspect relates to a system architecture that permits more than one slave system (e.g., a slave device) to be connected to a master system (e.g., a master device) in a communication system implementing a master/slave protocol. In one aspect, a pass-through device is provided that facilitates communication and authentication to one or more downstream slave devices. Yet another aspect relates to a star-based configuration of slave devices coupled to the master, and protocols for communicating and authenticating slave devices. Another aspect relates to a protocol that allows communication between entities without a priori knowledge of the communication protocol. In such a protocol, for example, information describing a data structure of the communication protocol is transferred between communicating entities.
