Extending Internet into SpaceESA DTN Testbed Implementation and Evaluation
Mobile Lightweight …, 2009
As the number and complexity of space missions increases, space communications enter a new era, where internetworking gradually replaces or assists traditional telecommunication protocols. The Delay Tolerant Network (DTN) architecture has recently emerged as a communication system for challenged networks, originally designed for the Interplanetary Internet. In the context of our project with ESA called "Extending Internet into Space -ESA DTN Testbed Implementation and Evaluation" we intend to deploy a distributed, flexible and scalable DTN testbed for space communications. The testbed will provide the supportive infrastructure for the design and evaluation of space-suitable DTN protocols, architectures, and routing policies to allow efficient deep-space communications. Throughout the project, we will demonstrate the operational capabilities of the DTN protocols in space; design and evaluate novel transport protocols and architectures for reliable data transfer in space; and investigate routing algorithms that comply with ESA's policies and resource status.
Space for Internet and Internet for Space
Space flight and Internet service are technologies that are currently complementary but seem to be on the verge of integration into a new “space internetworking” discipline. The authors believe a comprehensive realization of space internetworking technology could dramatically enhance space exploration, augment terrestrial industry and commerce, benefit the economically disadvantaged, and nurture human and civil rights.
