Why a Delay Tolerant Network?
Intermittent Connectivity: TCP/IP protocols fail when network partitioning occurs.
Long or Variable Delays: Long delays between nodes and variable queuing delays contribute to end to end delays defeating internet protocols and applications.
Asymmetric Data Rates: Large asymmetries in data rates are not supported by the Internet.
High error Rates: The error rate increases with the end-end retransmission of packets.
