Detailed Description

Used to cache information about packets whose responses have not yet been received.

We keep a map of send times keyed by identifiers. The identifier for a destination is incremented each time we send a packet to the destination, after which we insert a map entry with AddSent(). ProcessReceive() is called when we receive a packet, to look up the time at which the request packet was sent and hence calculate a round-trip time.
