| The Scalable Data Distribution Layer (SDDL) is ContextNet's communication layer that connects stationary DDS nodes in a wired “core” network to mobile nodes (MN) with an IP- based wireless data connection. Some of the stationary nodes are information and context data processing nodes, others are gateways for communication with the mobile nodes, and yet others are monitoring and control nodes operated by humans. SDDL employs two communication protocols: DDS’s Real-Time Publish- Subscribe RTPS Wire Protocol for the wired communication within the SDDL core network, and the Mobile Reliable UDP protocol (MR-UDP) for the inbound and outbound communication between the core network and the mobile nodes. | The Scalable Data Distribution Layer (SDDL) is ContextNet's communication layer that connects stationary DDS nodes in a wired “core” network to mobile nodes (MN) with an IP- based wireless data connection.
