Abstract
A persistent peer-to-peer network is implemented over a network with master-slave topology. Data being sent from master to slave or from slave to master are sent in one transmission, but data sent from one slave to another is received by the master and retransmitted to the slave. A session table is kept at each device includes an ordered list of devices, where the first device is the master device. When a master device drops out of the network the slave devices promote the next device in the ordered list of devices to master. A master device may also receive a request from a slave device to become master, and update its session table and send the updated session table to all devices. The slave device requesting master status is then treated as master by all devices in the network.
