  1. I believe that Advertisement and Discovery happen automatically, please correct me if I am wrong.
  2. In the case of multi-point sessions where more than one devices are connecting to a single service, a) How many concurrent devices can connect to a single server? b) What is the permissible bandwidth and data rate?

Applications built on top of an AllJoyn Client library (whether Standard or Thin) need to trigger advertisements (via AdvertiseName) or discovery (via FindAdvertisedName). Discovery does not happen automatically.

Even with the newer/recommended way of using About functionality, applications need to trigger advertisements (via Announce) or discovery (via WhoImplements).

The number of concurrent devices that can connect to one multi-point session host (or even multiple point-to-point sessions) can be set via Routing node configuration parameter max_completed_connections. The default value is 16 and as mentioned it can be configured to a different value.

AllJoyn sessions are built on top of AllJoyn transports which are abstractions on top of network layer functionality (essentially sockets) provided by the platform. Hence, AllJoyn doesn't place any limits on bandwidth or data rate, other than those in place due to the platform / medium itself.
