1.1.

Network Topologies

A networking topology defines how the network is connected. There are several different
topologies that can be defined in this respect


a.

Point
-
to
-
point

(P2P)
:

A single connection between two
devices

to directly
communicate with each other without interface from other devices.

Example:

two routers connected across a dedicated WAN circuit






b.

Star and extended star:

A central device with many P2P connections to other devices.

Example:

many computers connected via a HUB. To communicate with each other, each
device will have to go through the HUB (the central device). An extended star is
basically multiple star topologies interconnected.

10BaseT Ethernet uses star topology.




c.

BUS
:

A single connection or wire to connect all devices. 10Base5 and 10Base2 Ethernet
uses BUS
.




d.

Single and dual ring:

Device 1 connects to device 2, device 2 connects to device 3, and
so on to the last device, which connects back to device 1. It can be im
plemented using
single ring or dual ring. Dual ring is used for redundancy, if one of the device fails, the
other ring can still be functional.

Example:

FDDI (Fiber Distributed Data Interface) uses dual ring to connect computers.

1.1.1.

Physical Network
:

It
describes how devices are physically cabled together. For
instance, 10BaseT has a physical star connection, whereas FDDI has dual ring
topology.

1.1.2.

Logical Network
:

It describes how devices communicate with each other across
physical topology.

1.1.3.

Mesh Network
:

It is another method of connecting devices. It can be partial or full
meshing. It partial mesh, not all devices are connected to each other. Whereas in a
full mesh, all devices are connected to each other
.




1.2.

Network Types

1.2.1.

LAN


Local Area Network
:

LANs are used to connect networking devices that are
in a very close geographic area, such as a floor of a building, a building itself, or a
campus

environment. In a LAN, you’ll find PCs, file servers, hubs, bridges, switches,
routers, multilayer switches
, voice gateways, firewalls and other devices.
Usually a
corporation provides it’s own infrastructure for LAN.
The media types used in LAN
are Ethernet, Fast Ethernet (FE), Gigabit Ethernet (GE), Token Ring and FDDI. In
today’s network environment Ethernet
, FE and GE are very common.


1.2.2.

WAN


Wide Area Network
:

WAN is used to connect LANs together.
WANs are
used
when the LANs that must be connected are separated by large distance. Usually
WANs are leased for an ISP (Internet Service Provider) or carrier netwo
rks, such as


4

telephone company. WANs can be circuit
-
switched, cell
-
switches, packet
-
switched
or dedicated connections. WAN services include dialups, ATM, dedicated circuits,
cables, DSL, frame relay, ISDN, etc.


1.2.3.

MAN


Metropolitan Area Network
:

MAN is
hybrid between a LAN and a WAN.
Like a WAN it interconnects two or more LANs in the same geographic area. A MAN
might connect two different buildings or offices in the same city.

However, whereas
WANs typically provide low
-
to
-
medium speed access, MANs prov
ide high
-
speed
connection, such as T1 (1.544 Mbps) and optical services.


1.2.4.

SAN


Storage Area Network
:

SAN provides a high
-
speed infrastructure to move
data between storage devices and file servers. A storage device, which disk drives,
disk controllers, etc
. SAN can be dedicated to these devices or can be included other
devices. Typically fiber channels are used for the connection.


1.2.5.

RAN


Radio Access Network:

RAN is the ground based infrastructure required for
delivery of 3G (third
-
generation) wireless communication services, including high
-
speed mobile access to the internet. The RAN must be able to manage a wide range
of tasks for each 3G user, including acc
ess, roaming, transparent connection to the
public switched telephone network and the internet, and QoS (Quality of Service)
management for data and web connection.


1.2.6.

Intranet
:

An intranet is basically a network that is local to a company. In other
words

IP Routing Protocol Basics

There are three classes of routing protocols:


Distance Vector:

It finds the best path to a remote network by judging distance. Each time a
packet goes through a router, that’s called a
hop.

The router with the least

number of hops
to the network is determined to be the best route. The vector indicates the direction to the
remote network. Both
RIP

and
IGRP

are distance
-
vector routing protocols.


Link State:

It is also called the
shortest
-
path
-
first (SPF)

protocol.
Each router creates 3
separate tables. One of these tables keeps track of directly attached tables; one determines
the topology of the entire network and the last one used as the routing protocol.
OSPF

is a
link state routing protocol


Hybrid:

It uses aspe
cts of both distance vector and link state.
EIGRP

is a hybrid protocol.


9.2.

RIP


RIPv1,
RIPv2

& RIPng


RI
P (Routing Information Protocol) is a dynamic routing protocol and has been classified
as IGP (Interior Gateway Protocol). It uses distance
-
vector
routing algorithm. It uses “hop

count

as a routing metric.
Every 30 seconds it broadcasts the routing update information.
The hold down time is 180 seconds. The maximum number of hops allowed for RIP is 15.
The hop count 16 is considered an infinite dist
ance.
