A method for improved spreading of information in a network is described, together with corresponding methods with the opposite aim, namely to hinder the spreading of harmful information in a network. The harmful information may be (for example) a data virus. The first method includes as its characterizing feature to connect at least one node of high Eigenvector Centrality Index in a first region with at least one node of high Eigenvector Centrality Index in a second region. These connections may be made using direct links, or with the help of a new node lying between the nodes to be connected. One method for preventing spreading of information or physical traffic in a network may include as its characterizing feature to inoculate at least one center node by blocking any transmission of unwanted information on all links in/out of said center node. Another method for preventing spreading of information or physical traffic may be to inoculate all nodes in a ring of nodes surrounding a center node by blocking any transmission of unwanted information on all links in/out of said nodes. Still another method may be to inoculate at least one bridge link connecting two regions by blocking any transmission of unwanted information on said link.
