If you are behind a unique network topology with some firewalls that are blocking UDP packets OR a symmetric NAT, the direct connection using UDP hole punching will fail. Under such conditions, the COCONet will provision a fallback to a NAT traversal technique using a relay node. The security architecture in the COCONet is such that every node exchanges keys when they form the connection, and so even the relay node is unable to decrypt the data and the security of the network is maintained. Such an architecture, empowers Device makers (OEMs) and App developers to provide connectivity to their customers that is designed-for-privacy. The COCO platform handles all the communication routing, network transitions, security, encryption, and graph management so that the nodes remain connected to the P2P network with very high availability.
