A cornerstone of DIDO networks is the transport component, enabling nodes to communicate with a very high degree of trust and reliability. Although it is possible to create a network of nodes that do not use Internet Protocol (IP), the breadth and acceptance of such an endeavor is questionable.

DIDO relies on the transport layer as defined by the Open Systems Interconnection (OSI) Model. The transport layer is the layer in the open system interconnection (OSI) model responsible for end-to-end communication over a network. It provides logical communication between application processes running on different hosts within a layered architecture of protocols and other network components. The transport layer is also responsible for the management of error correction, providing quality and reliability to the end user. This layer enables the host to send and receive error corrected data, packets or messages over a network and is the network component that allows multiplexing.¹⁾.
