Which of the following is NOT a component of IPSec?
Security Association (SA)
Encapsulating Security Protocol (ESP)
Authentication Header (AH)
Simple Mail Transfer Protocol (SMTP)
This is a circuit-switched network. A dedicated circuit is established when the call is placed and remains in place throughout the call.
The local loop uses analog signals over POTS (through regular telephone cable wires). The long distance network typically uses digital signaling over fiber optic.
End-to-end speeds are limited to 56 Kbps, a restriction imposed by POTS in the local loop at each end.
A modem is required to convert digital signals to analog.
Remote access clients use this as a way to access the network or as a temporary or backup connection between sites.
Public switched telephone network (PTSN)
Integrated Services Digital Network (ISDN)
Distrubuted switching
Multiprotocol Label Switching (MPLS)
Wavelength-division multiplexing (WDM)
This has the following characteristics:
It is a circuit switching technology.
It is a local loop technology. When calls reach the WAN cloud, they are converted to another protocol for transmission through the WAN.
With BRI, you can use one channel for voice and one channel for data, or both channels for different voice calls. Depending on the implementation, you can also bond the B channels and use them together.
PRI requires a CSU/DSU for the T1 line.

Integrated Services Digital Network (ISDN)
Distrubuted switching
Multiprotocol Label Switching (MPLS)
Wavelength-division multiplexing (WDM)
This is an architecture in which multiple processor-controlled switching units are distributed. There is often a hierarchy of switching elements with a centralized host switch and remote switches located close to concentrations of users. Distributed switching:
Is often used in telephone networks, though it is often called host-remote switching.
Is used in rural areas, where population centers tend to be too small to economically deploy a full-featured dedicated telephone exchange. The distances between these centers make the transmission costs relatively high.
Public switched telephone network (PTSN)
Integrated Services Digital Network (ISDN)
Distrubuted switching
Multiprotocol Label Switching (MPLS)
Wavelength-division multiplexing (WDM)
This lassification and data-carrying mechanism.
It is a packet switching technology that supports variable-length frames.
It adds a label to packets between the existing Network and Data Link layer formats. Labels are added when the packet enters the this type of network and are removed when the packet exits the network.
Information in the label is used to switch the packet through this network to the destination.

Integrated Services Digital Network (ISDN)
Distrubuted switching
Multiprotocol Label Switching (MPLS)
Wavelength-division multiplexing (WDM)
This is a WAN technology that allows multiple signals to be carried along a single fiberoptic cable using different wavelengths of light for each signal.
Dense of this can carry 40 or 80 different signals.
Coarse of this can carry 16 different signals.
Bidirectional of this that enables signals to travel in both directions along a cable.

Distrubuted switching
Multiprotocol Label Switching (MPLS)
Wavelength-division multiplexing (WDM)
This uses a single phone line with a modem.
Dial-up uses a single 64-Kbps channel.
Common data transfer rates include 14.4 Kbps, 28.8 Kbps, 33.3 Kbps, and 56 Kbps.
Dial-up offers a minimum level of network connectivity for a low investment. It is available virtually anywhere that regular voice grade communications are available.
Computers dial an access server at the ISP. You must configure the system with the ISP server's phone number, along with a user name and password to log on.
The phone line cannot be used for voice and for the internet simultaneously.

Fiber
Satellite
This offers digital communications over existing POTS lines.
Data is sent using multiplexed channels over existing telephone wiring.
Implementation requires a specific router or a single network interface connected to the phone line.
This service is not available everywhere; the location must be within a fixed distance of network switching equipment.
There are several variations: asymmetrical, symmetrical, and very high.

Companies that provide cable television access typically offer internet access. Existing cable TV lines provide bandwidth for internet access.
Cable internet uses the Data over Cable Service Interface Specification (DOCSIS) that allows data signals to be sent on existing cable TV infrastructures. DOCSIS specifies channel widths, modulation techniques, and how core components of the network communicate.
A cable modem is a device that connects a computer system to the internet using a cable television network. But a cable modem doesn't function as a modem anymore because it doesn't modulate and demodulate a signal between an analog network and a digital end device. Many cable internet service providers (ISPs) are migrating to a fully digital network, including their television signals. Because of this, cable modems on digital systems are not modems. They are called media converters or cable terminal devices.

Fiber provides internet access using light signals transmitted to the end user on fiberoptic cables.
Fiber optic cables have an extremely low loss of signal, even over long distances, and aren’t at all affected by electromagnetic interference.
Fiber optic internet access requires a fiber optic modem at your location to convert the light signal into something your home router can use, either for Ethernet or Wi-Fi. Like cable internet, the bandwidth provided by fiber optic is shared by everybody who’s on the same segment. But this type of network is so much faster that service providers can often guarantee 1 gigabit per second speeds to every home. With that kind of speed, every computer, tablet, phone, and TV in your house can use the same connection at the same time with little to no buffering or lag.
