Abstract
In this chapter, the authors discuss the motivation, challenges, and solutions for network and Internet quality of service management. While network and Internet service providers traditionally ensured sufficient quality by simply overprovisioning their internal infrastructure, more economic solutions are required to adapt the network infrastructures and their backbones to current and upcoming traffic characteristics and quality requirements with sustained success. The chapter outlines real-world scenarios to analyze both the requirements and the related research challenges, discusses the limitations of existing solutions, and goes into the details of practitioners’ current best practices, promising research results, and the upcoming paradigm of service level management aware network connections. Special emphasis is put on the presentation of the various facets of the quality assurance problem and of the alternative solutions elaborated with respect to the technical heterogeneity, restrictive information sharing policies, and legal obligations encountered in international service provider cooperation.
