Abstract This paper summaries the recent research advance in the field providing congestion control mechanisms as powerful and flexible as the ones implemented by a stateful network. In a partial stateful or stateless network, three kinds of mechanisms are introduced for Internet routers: partial per-flow state, stateless core, congestion pricing and their representative implementation schemes are discussed in detail. The paper summaries this research field from the information and incentive point of view, discusses the internal relationships between these mechanisms and analyzes their performance characteristics.
