X-Bone dynamically deploys and manages Internet
overlays to reduce their configuration effort and
increase network component sharing. It discovers,
configures, and monitors network resources to
create overlays over existing IP networks. It uses
two-layer IP-in-IP tunneled overlays and supports
existing applications and unmodified routing,
multicast, and DNS services in unmodified
operating systems. X-Bone also support IPsec
within overlays.
