The most recent excerpt from the RELEASE-NOTES is included below. As always, this release is available at http://www.dtnrg.org/wiki/Code. Happy bundling! -mike --- 2.4.0 (July 2007) ----------------- - BBN updated the protocol implementation to conform to BP spec version 10, implementing bundle protocol version 5, converting most fixed-length fields to SDNVs and several other changes. - BBN added support for external convergence layers and data stores, matching the DTN reference architecture specification, as well as support for deleting links. - BBN added support for the metadata extension block and improved fragmentation handling. - Added a new router implementation called DTLSR (Delay Tolerant Link State Routing) intended for environments where the inter-node relationships are fairly stable, but links may go up and down. - Added support for forwarding a bundle with a wildcard destination to multiple next-hops, which can be used to implement simple or constrained flooding even with the static router. - Significantly improved the DTN simulator environment including adding support for bandwidth and storage limits on nodes, a structured output format for better post-processing of simulation results, and an internal restructuring making the simulation environment match the real-world environment much more closely. - Reworked the internal class used to represent bundle payloads so that the router can now support fully in-memory bundles which can safely contain binary data in all cases. - Jeff Wilson did a complete rewrite of the Prophet router implementation. - Changed the API to include bundle creation timestamp when receiving a bundle so that it's available to applications that may need it. - Added support for neighbor discovery that uses multicast dns (aka Apple's Bonjour protocol). Reworked the internal structure of the neighbor discovery subsystem. - Made optimizations to the table based routers (including the default static router) to be more efficient when links are coming up and down. - Updated the dtntunnel application to support tunnelling protocols where the server side is the first to send data. Reworked command line arguments to be more intuitive (and similar to ssh tunnels). - Added a dtntraceroute application that sends a single bundle, with a bunch of status report flags turned on and prints out the times embedded in the status reports that come back. - Modified the build environment to enable liboasys and libdtnapi to be built as shared libraries, and thereby used via SWIG export to other programming languages. - Resurrected the Cygwin build though it's not yet back to full functionality.

As you can, see, the difference between a Manet and a DTN is that the latter is much more generic and includes very different kind of challenges (the classical example: you usually do not include Space communications when researching Manets, while this is quite a common environment for those interested in DTN). Manets are a sub-category of DTNs, as Vanets are. Being a DTN many different things, if you want to simulate a DTN maybe you should try to understand to what level of generality you want your simulator to work and on which environment, for example starting for the area (a bluetooth Dtn could run in a km^2 area if tens of nodes are available, but different protocols can exhibit different abilities). Many of the works you mantion work at the link-up/link-down level since this is the most general to work with, and it caters for many different situations. If you want to model different adverse situation, you may be interested in simulating underwater communications or transmissions during electronic storms, say, by considering in the pattern of traffic also the noise, which is of course a more intense simulation than only considering disconnections and reconnections.

Good plan for DNS names, could be problematic for path names, but we can decide now that dtn: ssp's are to be case insenstive whenever they are ascii characters (might be difficult to state that precisely). > Adding the .dtn extension is just a convention that I've adopted in my > examples so that people don't think that they are DNS names by looking > at them (since they're not). Maybe that causes more confusion than it avoids though? Certainly threw me a bit. "_dtn.foo.example.com" would have been less confusing for me anyway (compared to "foo.example.com.dtn"). S.

In my config I get "dtn://Hostname.tcd.ie.dtn/*" because the of the "[info hosthame]" in the dtn.conf. But, the route in my case is set for "dtn://hostname.tcd.ie.dtn/*" which doesn't match (the bundle in this case is a custody ack). So, questions: 1) If I want to make that a case-insensitive SSP match, how'd I do that? 2) Should it be case insensitive or not? DNS names are, but the addition of the ".dtn" means these aren't DNS names really. (Why do we add ".dtn" anyway?
