Store and forward is a data communication technique in which a message transmitted from a source node is stored at an intermediary device before being forwarded to the destination node.
The store and forward process enables remote hosts, data connectivity and transmission, even if there is no direct connection between the source and destination nodes.
Store and forward is primarily implemented in telecommunication networks, where remote subscribers lack direct or dedicated connections. The store and forward technique works by storing the message transmitted by the source device on an intermediary device, generally a server. The server then locates the destination device from it database of subscribers, initiates a connection and transmits the data packet that was originally sent by the source device.
Store and forward is implemented in scenarios where the subscribing devices are geographically distant, lack direct connectivity and/or where the network is experiencing high error rates.
