Delay Tolerant Networks

Definition ∞ Delay Tolerant Networks are computer networks designed to operate effectively despite frequent disconnections and long transmission delays. These networks utilize a “store-carry-forward” approach, where data is held by intermediate nodes until a connection to the next hop is established. They are engineered to function in environments lacking continuous end-to-end network paths, such as interplanetary communication or remote sensor deployments. This architecture prioritizes eventual delivery over real-time connectivity.
Context ∞ The principles of Delay Tolerant Networks are gaining relevance in discussions about decentralized infrastructure, particularly for connecting remote or intermittently available nodes. Applications in blockchain could involve extending network reach to challenging environments or enhancing resilience against censorship. Research continues on integrating these concepts with distributed ledger technologies to bolster robustness.
