Abstract:

Current intra-domain transmission in the overlay network ignores the leader-followers game characteristic between the Internet service providers and user. This will result in the problem of not achieving the best optimization state because the intra-domain transmission in real network applications may lack a reasonable equilibrium point. To solve this problem, a hierarchical overlay network architecture based on multi-agent game was proposed. Through constructing the leader-followers stackelberg game model between Internet service provider agent and user agent. Based on this model, the existence and uniqueness of Nash equilibrium was analyzed to get the best price and transmission rate under the Nash equilibrium state. Then, a quantitative description of the network’s best running was given. Finally, the effect of network topology parameters on the best running state was analyzed.

Key words: overlay network, hierarchical architecture, multi-agent, leader-followers game
