Proxy pair optimizations for increased service reliability in DIL networks

Using Commercial off-the-shelf (COTS) software over networks that are Disconnected, Intermittent and Limited (DIL) may not offer acceptable performance. Frequent network interruptions for both shorter and longer periods, as well as long delays, low data and high packet error rates characterize DIL networks. In this paper, we designed and implemented a prototype proxy to improve the performance of Web services in DIL environments. The main idea of our design was to deploy a proxy pair to facilitate robust HTTP communication for Web services. We evaluated using alternative transport protocols to carry information across these types of networks: The Hypertext Transfer Protocol (HTTP), the Advanced Message Queuing Protocol (AMQP) and the Constrained Application Protocol (CoAP). This work was performed in context of the NATO RTG-IST-150 “NATO Core Services profiling for Hybrid Tactical Networks” group.
