Interconnection WG: Charter

Address the multidisciplinary problems of connectivity in a multicarrier Internet:

-- Economic/business models-- Empirical research-- Architecture

to promote healthy growth across the value chain, sound policy, and a better understanding of key challengesposed by growth of broadband traffic and transition to NextGen Internet

Network Interconnection: Theory and Models

Understanding incentives to interconnect in multicarrier Internet

Economic theory: 2-sided markets and network platform competition

Industry structure: Understanding overlay networks-- Content delivery -- Security overlays-- Routing overlays

Evolution of interconnection: from peering & transit to ??
