On model-driven self-engineering of inter-domain traffic

Realizing autonomic networking is possible with the clear understanding of required control mechanisms under multiplexing. Attempting such understanding ecosystem is motivated as a novel unit of design, exemplified by the two extreme cases - micro-ecosystem of a single buffer with random early detection mechanism, and macro-ecosystem of a path of autonomous systems sharing traffic handling to the same destination prefix. Both problems are formalised as model-driven information coupling of distributed controllers, implicit for the micro, and explicit for the macro-ecosystems. The main contributions are ecosystem examples and their driving models; the geometry based route view diagram driving self-engineering of traffic is original, while linear bound of packet loss ratio driving the micro-ecosystem is borrowed from the literature and adapted.
