OpenSky service under Linux

OpenSky is the latest satellite service and it offers 300 MB at month (for

Firstly, VoIP doesn't use TCP because it is too heavy for real time applications,
|
||||
so instead a UDP (datagram) is used.
|
||||
</p>
|
||||
<p>
|
||||
In UDP we cannot ordering packets in arrive time (which is a must in VoIP)
|
||||
because there isn't connection idea, each packet is independent from others
|
||||
(datagram concept); so we have to introduce a new protocol, such as RTP, able
|
||||
to manage this.
|
||||
Secondly, UDP has no control over the order in which packets arrive at
|
||||
the destination or how long it takes them to get there (datagram concept).
|
||||
Both of these are very important to overall voice quality (how well you can
|
||||
understand what the other person is saying) and conversation quality (how easy
|
||||
it is to carry out a conversation). RTP solves the problem enabling the receiver
|
||||
to put the packets back into the correct order and not wait too long for packets
|
||||
that have either lost their way or are taking too long to arrive (we don't
|
||||
need every single voice packet, but we need a continuous flow of many of them
|
||||
and ordered).
