`
`Resilient Overlay Networks
`
`Today's Internet backbone is effectively non-transitive. You may be able to visit
`MIT, and MIT may be able to visit a site in which you're interested, but that's no
`guarantee that you can visit that site.
`Relaxing that a bit farther, there is considerable evidence that for technical and
`political reasons, routing on the internet frequently ignores paths which may be
`better able to carry traffic. From a security perspective, an attacker's job is made easier because restricted routing creates
`more single points of failure which an end-user is unable to simply "route around."
`The resilient overlay networks project is designing a framework which can be used by either applications or network routers
`to take advantage of these traffic shunts to improve performance. RON nodes will self-configure an overlay network to
`transmit packets over the underlying Internet infrastructure which will automatically select paths to avoid network problems.
`Because of their relatively small size (under 50 nodes), RONs will be able to take advantage of more aggressive path
`selection and detection methods than conventional internet routers. Because RONs are administered in a single domain, they
`can incorporate additional security features (like a secure VPN), and they can base their path selection upon their own
`requirements, not a global approximation such as shortest path.
`Components of the project:
`End-to-end low-impact active performance measurement
`Routing and topology maintenance (courtesy of INS)
`Integration of performance data in an easily accessible performance database.
`Libraries for easy application use of overlay networks.
`RON router nodes, using Click to provide transparent encapsulation of packets into the overlay network.

`"I'm happy to announce the release of v2.0b1 of the SPAND toolkit. SPAND (Shared Passive Network Performance
`Discovery) is a system that allows applications to measure the application-level network performance to distant
`network sites, share that information with other clients, and use the information to make intellegent application-level
`decisions."
`A USITS paper by Srini and Mark describes SPAND [ps] [local ps]
`Mark Stemm's thesis is available: [html] [ps] [local ps] , and it discusses SPAND in detail.

`The Detour Project at the University of Washington. They developed "sting", which uses TCP to determine forward
`and reverse path packet loss rates.
`Yallcast is an open-source project to develop software allowing hosts to form a content distribution topology. Their
`architecture paper is available in [html] [ps] [local ps] formats. They want to position themselves above TCP/IP but
`below the application. They create a tunnelled shared tree topology and a tunnelled mesh
`Commercial products
`There are several commercial products which use some of the techniques we're exploring. VisualRoute measures per-
`hop loss and delays. VitalSigns' NetMedic product uses bprobes and application-specific metrics to report network
`performance.
