This research explores methods to increase the performance of HTTP traffic when operating on a network that is prone to disrup-tions. The SmartNet architecture is presented as an open and extensible software framework for experimenting with and deploying application-transparent network optimization solutions, including the incorporation of the disruption tolerant networking (DTN) and split TCP (SplitTCP) technologies into an IP network. The architecture fashions a plugin-based system architecture where each plu-gin implements a small set of application or transport protocol specific network adaptations that can be chained with other plugins to form a packet processing pipeline. The SmartNet framework is implemented along with plugins to route packets through native-IP, the Bundle Protocol, or SplitTCP. Performance of the SmartNet is measured under five network disruption patterns and five link speeds. The results conclude that HTTP performance can be increased by using the SmartNet to transparently route packets over the DTN bundle protocol or SplitTCP when the network is prone to disruptions.
