Dynamic Discovery

enables a sending access point at corner 2 in a four corner model to dynamically discover the IP address and receiving capabilities of the receiver at corner 4. The sender consults a Service Metadata Publisher (SMP) where information about a participant in the exchange network is maintained. There could be multiple SMPs, maintaining a unique ID (URL) for its participants, which are published by the Service Metadata Locator (SML) on the network’s Domain Name System (DNS). By knowing this URL, the sender is able to dynamically locate the right SMP appropriate to a specific receiver.
