QoS in Internet2
John J. Sikora · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2001
Internet2 is a consortium of over 170 universities who are working with industry partners and government agencies to create a high-sped next generation Internet where new research and educational applications and techniques can be tried. The intent is to recreate the spirit of the original Internet to foster innovations in Internet technology and use. Quality of Service (QoS) was built into Internet2 from the beginning. A QoS working group was formed early in the planning stages of Internet2 to define and oversee its QoS approach. This paper gives an overview of the QoS architecture that the QoS working group devised for Internet2, and the resulting Internet2 testbed, known as the Qbone, which the group oversees. The architecture is based on the IETF differentiated services (DiffServ) technique, which was found to meet the requirements that the group formulated. IN particular, the ability of DiffServ to guarantee service levels for individual applications while remaining highly scalable and interoperable was important. Potential uses of the Qbone and some current plans for the Qbone are also discussed.
