Tariffs and Traffic
The reliable operation of a public multiservice broadband
network raises design issues both within the subnetworks
run by individual network operators, and at the interfaces
between these subnetworks. Some of these issues are of an
engineering nature, concerning stability and control over
fast timescales. Others are of an economic nature,
involving coordination between distinct commercial
entities. In future networks the intelligence embedded
in end-systems, acting on behalf of users, is likely to
lessen the distinction between engineering and economic
issues. We illustrate the resulting interactions between
tariffs and traffic with a discussion of a few specific
topics: characterization effort for guaranteed services,
routing procedures initiated by end-systems, and rate
control algorithms for elastic traffic.
in communication networks: shadow prices, proportional
fairness and stability.
