- A Virtual Path Source Routing Procedure:
-
- Expanding on the idea of path building for applications which
- want to open a path within microseconds, send a burst of data,
- then close the path, a protocol could be developed which requires
- some pre-discovery of routes (like source routing) then re-use
- this route map each time a circuit is opened.
-
- Using wave, (of course), a desktop can perform route discovery by
- launching an exploratory wave which uses a user selectable costing
- mechanism to find one main and possible alternate routes to commonly
- used destinations. The discovered routes would be collected in wave
- syntax, allowing the encoded routes to be released in their exact
- form for fast circuit building (again using wave syntax).
-
- Just prior to transmission, a circuit blazer wave would precede the
- data, opening up the path tables to the destination, then closing the
- tables when data transmission is complete. The encoded route would
- be used repeatedly for more of the same.
-
- In this application, the address resolution protocol (ARP) does not
- result in a completed path, just in an encoded route.
