Library with real-world network topologies (most popular: Abilene) and sometimes traffic/service demands: http://sndlib.zib.de/ Under Library > Dynamic traffic there are realistic traffic traces that are dynamically changing over time. For example traffic matrix from every 5min over 6 months for the Abilene network. Also for every 15min for the larger Geant network
