FIELD: physics, computer engineering.SUBSTANCE: group of inventions relates to computer networks. Each mobile device can establish a primary peer-to-peer (P2P) communication channel with one or more other mobile devices. Once the primary channel is established, each mobile device can use the primary channel to exchange secondary channel connection data and can subsequently open one or more secondary P2P communication channels with the other mobile devices. Upon detecting that the primary P2P communication channel has failed or has deteriorated below a specified threshold (e.g., a certain bandwidth or bitrate threshold), one of the secondary P2P communication channels can be automatically promoted to a primary P2P communication channel.EFFECT: establishing, supporting and using backup channels in a P2P network.24 cl, 30 dwg, 3 tbl |
