<h2 class="mdl-card__title-text">How It Works</h2>
|

</div>
|
||||
<div class="mdl-card__supporting-text">
|
||||
|
||||
<p>
|
||||
The Internet isn't exactly like radio waves:
|
||||
it still goes at near the speed of light,
|
||||
but there are multiple hops between endpoints,
|
||||
which buffer up transmissions, and multiplex them onto a single uplink connection.
|
||||
These repeaters (routers)
|
||||
are also allowed to just drop things if they need to.
|
||||
It's the responsibility of the communicating parties
|
||||
to work out whether something needs to be retransmitted.
|
||||
Because of this,
|
||||
there's no telling how long it will take for a transmission to get to a destination.
|
||||
</p>
|
||||
|
||||
<p>
|
||||
Each Vail transmission (packet) consists of:
|
||||
</p>
|
||||
<ul>
|
||||
<li>timestamp (milliseconds since 1 Jan 1970, 00:00:00 in Reykjavík)</li>
|
||||
<li>transmission duration (milliseconds)</li>
|
||||
<li>silence duration (milliseconds, optional)</li>
|
||||
<li>transmission duration (milliseconds, optional)</li>
|
||||
<li>silence duration (milliseconds, optional)</li>
|
||||
<li>Repeat as necessary</li>
|
||||
</ul>
|
||||
|
||||

|
||||
The repeater does nothing but broadcast everything it gets
|
||||
to every connected Vail client,
|
||||
including the one that sent the packet.
|
||||
When your client gets back the exact same thing it sent,
|
||||
it compares the current time to the time in the packet.
|
||||
This is the <i>round-trip time</i>:
|
||||
the time it takes for a packet to get from your computer to the repeater and back.
|
||||
</p>
|
||||
|
||||
<p>
|
||||
When the client gets a packet it didn't send,
|
||||
it adds the <i>receive delay</i> to the timestamp,
|
||||
and schedules to play the tones and silences in the packet
|
||||
at that time.
|
||||
</p>
|
||||
|
||||
<p>
|
||||
By adding the maximum round-trip time to the <i>longest recent transmission</i>
|
||||
(the length of a dah, hopefully),
|
||||
your client can make a guess about how much time needs to be added to a received timestamp,
|
||||
in order to have it play back in the future at the time it comes in.
|
||||
This is just a guess.
|
||||
If you're communicating with somebody with a higher round-trip time than you have,
|
||||
you'll need to raise your receive delay to account for it.

||||

<div class="mdl-card__supporting-text">
|

<p>
|
||||
This is the "drop tone", and will be accompanied by an error.
|
||||
</p>
|
||||
|
||||
<p>
|
||||
This means the packet arrived so late, it can't be played in time.
|
||||
In technical terms: the timestamp of the packet plus the receive delay
|
||||
is less than the current time.
|
||||
It can't be scheduled to play, because we can't go back in time.
|
||||
</p>
|
||||
|
||||
<p>
|
||||
This could be happening for three reasons:
|
||||
</p>
|
||||
|
||||
<ol>
|
||||
<li>You (the person hearing the drop tone) need a larger receive delay</li>
|
||||
<li>The receiving computer's clock is in the future (running fast)</li>
|
||||
<li>The sending computer's clock is in the past (running slow)</li>
|
||||
</ol>
|
||||
|
||||
<p>
|
||||
Make sure your clock is synced with an Internet time server.
|
||||
Accurate time is very important to how Vail works.
