<hr><a name="_details"></a><h2>Detailed Description</h2>
Abstraction for a DTN link, i.e.
<p>
a one way communication channel to a next hop node in the DTN overlay.<p>
The state of a link (regarding its availability) is described by the <a class="el" href="classdtn_1_1Link.html#1bf2479a21276737f73204a3c46508a3" title="The possible states for a link.">Link::state_t</a> enumerated type.<p>
All links in the OPEN state have an associated contact that represents an actual connection.<p>
Every link has a unique name associated with it which is used to identify it. The name is configured explicitly when the link is created.<p>
Creating new links: Links are created explicitly in the configuration file. Syntax is: <div class="fragment"><pre class="fragment"> link add <name> <<a class="code" href="classdtn_1_1Link.html#5bffae252da80b32679686d826f4d4cf" title="Accessor to next hop string.">nexthop</a>> <<a class="code" href="classdtn_1_1Link.html#75dad1b5cff2bd5e84b06ffc57504c65" title="Return the type of the link.">type</a>> <conv_layer> <args>
</pre></div> See <a class="el" href="LinkCommand_8cc.html">servlib/cmd/LinkCommand.cc</a> for implementation of this TCL cmd.<p>
----------------------------------------------------------<p>
Links are of three types as discussed in the DTN architecture ONDEMAND, SCHEDULED, OPPORTUNISTIC.<p>
The key differences from an implementation perspective are "who" and "when" manipulates the link state regarding availability.<p>
ONDEMAND links are initializd in the AVAILABLE state, as one would expect. It remains in this state until a router explicitly opens it.<p>
An ONDEMAND link can then be closed either due to connection failure or because the link has been idle for too long, both triggered by the convergence layer. If an ONDEMAND link is closed due to connection failure, then the contact manager is notified of this event and periodically tries to re-establish the link.<p>
For OPPORTUNISTIC links the availability state is set by the code which detects that there is a new link available to be used.<p>
SCHEDULED links have their availability dictated by the schedule implementation.<p>
----------------------------------------------------------<p>
Links are used for input and/or output. In other words, for connection-oriented convergence layers like TCP, a link object is created whenever a new connection is made to a peer or when a connection arrives from a peer.
