Sedona

Device Discovery

Introduction

Sedona Framework (starting with version 1.2) provides a mechanism for performing Sedona device discovery using a special DASP message directed to a multicast address. Any Sedona device on the network that has joined the multicast group then responds to the message with its platform ID and IP address.

Basic Operation

  1. Join: Each Sedona device that supports DASP device discovery joins a specific IP multicast group at startup.
  2. Discover: The Sox client kicks off a device discovery process by sending a DASP DISCOVER request to the multicast group address.
  3. Respond: When a device receives the DISCOVER message, it sends a response containing its address and platform ID.
  4. Process: The client processes any DISCOVER responses it receives, and maintains a cached list of devices that responded.
