VoIP
Sevice
VoIP service is
unlike the standard telephony systems that we
use
today. Instead of using the
old system of circuit switching, data is sent via the internet
using a protocol called packet switching. This means that instead
of you waiting for a connection to a website, information flows
constantly throughout the network via thousands of possible connections.
Ppackets (messages
or fragments of messages) are individually
routed between nodes, with no previously established communication
path. This makes packet switching fast and efficient.
The computer that sends
the data, creates small packets of data with individual unique
addresses. Each packet represents one part of the overall file,
which could be a page, text document or music file.
Once all the packets have been received by the recipient computer, it uses
their unique addresses to reassemble the file. This is the same process
that VoIP uses to make a call. Your voice is converted into thousands of
compressed packets that are sent to another computer, then reassembled
on arrival.
