Abstract: Techniques are disclosed for exchanging anonymized information between autonomous systems. In one example, a method comprises accessing an eigenvalue, wherein the eigenvalue is based on topology data associated with the first autonomous system; encoding the eigenvalue into a message; and transmitting, by a network element located in the first autonomous system, the message to an external edge router located in the second autonomous system. A further method can comprise receiving, by a network component located in a first autonomous system, a message, wherein the message comprises an eigenvalue and the message is received from an external network element located in a second autonomous system; accessing another other eigenvalue, the another eigenvalue corresponding to an autonomous system different from the first autonomous system; analyzing the another eigenvalue and the eigenvalue; and executing, by the network element, an action based on the analyzing.
