-<p>Collection provides a best-effort, multihop delivery of packets to one
-of a network's tree roots: it is an <em>anycast</em> protocol. The semantics
-is that the protocol will make a reasonable effort to deliver the
-message to at least one of the roots in the network. By picking a
-parent node, a collection protocol inductively joins the tree its
-parent has joined. Delivery is best effort, and there can be
-duplicates delivered to one or more roots. Collection provides no
-ordering guarantees. Collection does not provide real-time guarantees,
-although specific implementations may extend the basic functionality
-to do so.</p>
