The Diffusion of Networking Technologies
نویسندگان
چکیده
There has been significant interest on the impact of cascade effects on the diffusion of networking technology upgrades in the Internet. Thinking of the global Internet as a graph, where each node represents an economically-motivated Internet Service Provider (ISP), a key problem is to determine the smallest set of nodes that can trigger a cascade that causes every other node in the graph to adopt the protocol. We design the first approximation algorithm with a provable performance guarantee for this problem, in a model that captures the following key issue: a node’s decision to upgrade should be influenced by the decisions of the remote nodes it wishes to communicate with.
