Abstract

The RADAR protocol and its underlying neighbourhood discovery framework extend the ANTS toolkit by giving active nodes the ability to discover dynamically other active nodes close to them without relying on any con.guration .le. Such an automatic discovery is the key to administration of large or sparse active networks and the first step towards an e.cient active routing. Active nodes will use their local IP routing table to run an extended ring search in their domain. An Additive Increase Multiplicative Decrease control allows RADAR to discover several neighbours per physical interface without searching too far away or .xing a maximum distance a priori. The protocol is complemented by a traffic-driven discovery that can grab capsules coming from unknown nodes (mainly outside the local domain) and trigger targetted probing of those addresses.
