Storeandforward
Store-and-forward is a method of relaying data in which data is temporarily stored at intermediate nodes before being forwarded to the next hop or recipient. The approach contrasts with cut-through or circuit-forwarding methods that begin forwarding as soon as enough of a message is received. In a store-and-forward system, the complete unit of data—such as a frame, packet, or message—is typically stored, error-checked, and then transmitted onward when the next link or node is ready.
In computer networks, store-and-forward switching refers to a network device buffering full frames or packets, performing
In email and messaging systems, store-and-forward describes how messages are delivered by intermediate servers. A sender
Store-and-forward is also used in delay-tolerant networks and in telemedicine. In delay-tolerant networks, data is buffered
Advantages include improved reliability, error checking, and decoupling of sender and receiver. Disadvantages include higher latency
