Abstract
A technology is described for distributing a publication message. An example method may include receiving a message at a first device gateway to broadcast to devices subscribed to a broadcast topic. The first device gateway maintains a first subscription table indicating which devices connected to the first device gateway are subscribed to the broadcast topic. The first device gateway distributes the message to the devices indicated in the first subscription table as being subscribed to the broadcast topic. In addition, the first device gateway may distribute the message to a second device gateway which maintains a second subscription table indicating which devices connected to the second device gateway are subscribed to the broadcast topic, and the second device gateway distributes the message to the devices indicated in the second subscription table as being subscribed to the broadcast topic.
