Internet. VoIP enables a router to deliver voice traffic (e.g. phone calling and
facsimile) over an IP network. Over VoIP, DSP decomposes voice signals into
frames, and a pair of the decomposed frames is grouped. Then, the grouped frames
are saved in a voice packet. The voice packet is forwarded by using an IP under the
ITU-T standard, H.323.
VPN
Stands for Virtual Private Network. VPN allows you to encrypt entire traffic that
moves from a network to another network so that IP traffic can safely move over a
public TCP/IP network. On VPN, all data is encrypted in an IP level by using the
‘tunneling’ technique.
WAN
Stands for Wide-Area Network. WAN is a data communication network that provides
services to the users in a wide area and that uses transmission services provided by
regular service providers. Examples of WAN include frame relay, SMDS, and X.25.
