VoIP
Voice over IP enables Cisco routers to carry voice
traffic (for example, telephone calls and faxes)
over an IP network. In Voice over IP, the digital
signal processor segments the voice signal into
frames, which are then coupled in groups of two
and stored in voice packets.

VPN
WebVPN: This feature enables secure remote
access through SSLVPN on Cisco IOS routers.
access through SSLVPN on Cisco IOS routers.
IPSec: IPSec provides security for transmission of
sensitive information over unprotected networks
such as the Internet. IPSec acts at the network
layer, protecting and authenticating IP packets
between participating IPSec devices (“peers”),
such as Cisco routers.

IKE: The Internet Key Exchange (IKE) protocol is
a key management protocol standard which is
used in conjunction with the IPSec standard.
IPSec is an IP security feature that provides robust
authentication and encryption of IP packets. IPSec
can be configured without IKE, but IKE enhances
IPSec by providing additional features, flexibility,
and ease of configuration for the IPSec standard.

L2TP: Layer 2 Tunneling Protocol
MPLS: Multiprotocol label switching, MPLS (or
Tag Switching), combines the performance and
capabilities of Layer 2 (data link layer) switching
with the proven scalability of Layer 3 (network
layer) routing. MPLS enables service providers to
meet the challenges of explosive growth in
network utilization while providing the
opportunity to differentiate services without
sacrificing the existing network infrastructure.
The MPLS architecture is flexible and can be
employed in any combination of Layer 2
technologies. MPLS support is offered for all
Layer 3 protocols.
