A Divert Mechanism for Service Overlays
Shared overlay nodes such as the ones in PlanetLab
enabled a new perspective on overlays, in which a user can subscribe to
arbitrary overlays, each of which implements some network service
on behalf of the user's applications.
We have designed and implemented a general-purpose mechanism to
transparently divert packets belonging to designated applications onto
service overlays, and we demonstrated how our mechanism can be used to
divert packets from applications like http, ssh, sftp onto a
RON-based routing overlay.
