The
Internet is the greatest communications development
of the 20th century's.
All Communications over the Internet could not ever exist
without an “intelligent” piece of equipment called: the
Router.
The Router is the crucial device that let messages flow between
networks and determines the next network point
to which a data packet should be forwarded enroute toward
its destination.
Routers are specialized software based devices that send your
messages over the Internet to their destinations along thousands
of pathways and determines which way to send each data packet
based on its current understanding of the state of the networks
it is connected to. Routers create or maintain a routing
table of the available routes and use this information
to determine the best route for a given data packet.
 The
routers link two networks together and at the same time connect
both networks to the Internet. The router has two separate
- related jobs:
· The router makes sure that information does make it to the
intended destination.
· The router ensures that information doesn't go where it's
not needed.
The router
can route traffic in one of two ways; statically, or dynamically.
For a small network with few routes, static is a fine solution.
Static routing requires an administrator to manually enter
the parameters for routing traffic. This would be known as
a static routing table. A
static routing table can be implemented in such
a way as to allow all traffic from an entire network or subnet
to be routed to a particular destination or out a particular
interface. Additionally individual addresses or all traffic
for that matter can be routed in the same way. This method
does not scale well though. It is for this reason that we
have conceived Routing Protocols. A routing
protocol is a standard means for network-connected
equipment to share information concerning networks that they
have knowledge of.
The routers are passing information from one to the other
and at the same time are protecting the networks from one
another as well as performing translations of various
routing protocols between networks.
A router running a routing protocol can dynamically
discover, store, and share information about networks that
it is directly connected to, or is informed of, by other routers
running the same protocol. Routing
protocols, all have their own properties, and
uses. Some are fine for routing on a small to medium network;
others have been engineered to handle networks with tens of
thousands of nodes. Others are made to handle transitions
from internal routing environments to external environments
or on the Internet at large. Some of the most common routing
protocols include
RIP, IGRP, OSPF, and BGP. All of these routing
protocols have their advantages and drawbacks.
Some routing protocols transmit large routing tables to one
another. Others do complex calculations based on a number
of different metrics in order to find the best route to send
information to their destination.Knowing where and how to
send a message is the most important job of a router.
 Since
the Internet is one huge network made up
of tens of thousands of smaller networks, its use of routers
is an absolute necessity. Internet data, whether in the form
of a Web page, a downloaded file, an e-mail message, a voice
or video conversation, travels over a system known as a
packet-switching network. In this system the data,
in a message or file, is broken up into packages about 1,500
bytes long. Each of these packages gets a wrapper that includes
information on the sender's address, the receiver's address,
the package's place in the entire message, and how the receiving
computer device can be sure that the package arrived intact.
Each data package, called a packet, is then
sent off to its destination via the best available route;
a route that might be taken by all the other packets in the
message or by none of the other packets in the message. If
there is a problem with one piece of equipment in the network
while a message is being sent, packets can be routed around
the defective piece of equipment, ensuring the delivery of
the entire message.
To make these decisions the routers must know two kinds of
information about every piece of equipment that connects to
a network: network
addresses and network
structure. The routers know the format of the
addresses, how many bytes are in the basic packet of data
sent out over the network, and how to make sure that all the
packets reach their Destination and get Reassembled.
The job of the Routers in the
network is to look at the destination address and compare
it to their lookup table to find out where to send the packets.
Manufacturers, such as Cisco
Systems, have designed the majority of their
routers to be modular in nature. This philosophy not only
protects the end user in terms of allowing them to use new
interface or module technology on an existing platform chassis,
but also in the short term, allows them to re-deploy their
routers anywhere across their networks, they desire. By simply
purchasing the card or module that is designed to interface
with that type of physical link can save tens of thousands
of dollars over the life of the router. Cisco
Systems is the largest router manufacturer in
world.
 Everyone
who has a network needs a router; this is the one constant.
The thing that needs to be considered when looking for a router
is scalability, reliability, functionality and performance.
