Summary of Papers covered:
The first paper in the group [1] discusses the issues with networks that are non traditional, relative to Internet Protocols and their application towards those networks, classified as challenged networks. The papers identifies the characteristics by which these networks operate, argues why traditional IP cannot be directly applied to these networks. The paper then proposes an generic network architecture for communication over these challenged networks, such that they are interoperable with the traditional IP based networks that we all are aware of. The network architecture proposed can be made interoperable, by abstracting out dependencies of the transport from the application itself and having the application interface to an well known set of APIs, which are consistent across multiple challenged networks. The goal of such abstraction allows the author to provide a vision for communication between multiple networks of internets, which is discussed in the second paper [2]. Interplanetary Internet provides a architecture (first paper is generalization of the second paper in the group) for communication between computer nodes connected to earth stations and then on to long haul satellites and eventually to orbiters and their associated space vehicles. The goal of such architecture is to have interoperability at multiple levels of the communication stack between space agencies, that promotes higher level of cooperation and hence better research. The model proposed in the second paper has been actively prototyped on Linux based systems.
