DTN may not be of use in many environments and applications
- Depends on ideal data policies
- No point bundling, retransmitting PLI when it'll just be broadcast again shortly
- Only key parts of streaming media should be rebroadcast
Attempts to apply knowledge of application semantics to recover data as appropriate
- Application state snapshots
- Transcripts
- Segments of streaming media
Extends HIF
- Many MANETs interconnected by quasi-static upper-echelon backbone with higher bandwidth
- This is where filtering really needs to happen
Network-based data transformation
Interest aware content distribution
Users manually request a resync; responses are unicast back to node
- Spoofed locally, multicast with TTL 1 in order to avoid changing c2mincs API
MPEG7 can embed metadata that would be useful for only caching segments of interest
Current implementation simply replays most recent n seconds
- Separate media stream since the original may be in use
