Alleviating Bundle Throughput Constriction for Delay Tolerance Networking (DTN) Bundles with Software-Defined Networking (SDN)A load-balancing technique is proposed, executed, and tested against a Delay Tolerant Network (DTN) implementation with well-known characteristics. This would prove that transparently inserting software defined networking (SDN) to achieve load balancing without re-configuring the DTN portion is possible.

Two routes were taken to alleviate a DTN bottleneck threat. The first used a P4 networking switch. This manual load-balancing test will balance the incoming packets without the users at the end-points knowing that its original packet destination and/or source may have been changed. The second route utilized a High-rate Delay Tolerant Networking (HDTN) receiving node instead of the typical the delay tolerance networking (DTN) implementation used. Bench-marking results of the DTN implementation receiving node and the HDTN receiving node will be compared.
