End-to-End Quality of Service Architectures for Internet Protocol based satellite communication are evolving. Cisco Systems, Inc. Next Generation Global Services Space-based Internet provides an integration challenge for providing end-to-end Quality of Service utilizing the first full Internet Routing in Space payload router located in geostationary orbit. This first Space-Based Internet consists of a payload router/modem ground based terminals and Network Operations Center. The payload is hosted on the Intelsat IS-14 geostationary satellite, due to be launched in 2009. Internet Routing In Space Next Generation Global Services are being developed as a Joint Capability Technology Demonstration for the US Department of Defense. The Space-based Internet introduces an advanced Quality of Service Architecture in support of providing Service Level Agreement based managed services. We first introduce the QoS functionality and propose a simplified QoS model to integrate the components for an end-to-end architecture. Integration challenges are discussed and are being studied in a high fidelity proof of concept lab. Future QoS integration research areas are introduced.
