The changing role of the Internet Engineering Task Force (IETF) standard
setting process, from designing and implementing the best effort transmission
control protocol/Internet Protocol (TCP/IP) as a universal standard towards a
platform for dealing with the increasing need for variety in the design of a Quality
of Service (QoS) differentiated traffic management architecture, is demonstrated.
The IETF’s contributions to flexible open transmission architecture, able to
provide the required traffic qualities for the different applications, constitute the
relevant pillars of a Generalized Differentiated Service (DiffServ) architecture.
Further, the role of entrepreneurial traffic management within the Generalized
DiffServ architecture, and the division of labor between the IETF and entrepreneurial traffic management, is analyzed. Within the “umbrella” architecture of Generalized DiffServ with the potential to combine basic elements of QoS differentiated traffic architectures, a flexible framework for entrepreneurial traffic quality differentiation strategies is evolving. Its basic characteristic is marketdriven network neutrality with all applications bearing the opportunity costs of their required traffic capacities. Consequently, an artificial market split between
best effort TCP/IP and managed services would conflict with the integrated
service approach of the IETF. Finally, the implementation of Generalized
DiffServ via Next Generation Networks is considered.
