Configuring TCP/IP

Understanding the TCP/IP Protocol



Transmission Control Protocol (TCP)



Provides connection
-
oriented, reliable communication
between two hosts, typically involving large amounts of data.



User Datagram Protocol
(UDP)



Used for fast, nonconnection
-
oriented communications with no
guarantee of delivery, typically small short bursts of data.



Internet Protocol (IP)



Handles, addresses, and routes packets between hosts on a networks.



Internet Control Messaging Protoc
ol (ICMP)



Enables hosts on a TCP/IP betwork to share status
and error information.



Address Resolution Protocol (ARP)



Used to resolve the IP addresss of the destination computer
to the physical or Media Access Control address, which is a inique 12
-
digit

hexadecimal number
that is burned into ROM on every network adapter.



IPv6:

o

An efficient hierarchical addressing scheme
: Ipv6 addresses are designed to enable an
efficient, hierarchical, and summarizable routing scheme, making way for multiple levels
of In
ternet service providers (ISPs).

o

Simpler routing tables
: Backbone routers on the Internet are more easily configured for
routing packets to their destinations.

o

Stateful and stateless address configuration
: Ipv6 simplifies host configurations with the
use o
f stateful address configuration (configuring IP addresses in the presence of a
Dynamic Host Configuration Protocol [DCHP] server) or the use of stateless address
configuration (configuration IP addressess in the absence of a DHCP server).

o

Improved securit
y
: Ipv6 includes standards
-
based support for IP Security (IPSec).

o

Support for Link
-
Local Multicast Name Resolution (LLMNR)
: This enables Ipv6 clients on
a single subnet to resolve each other’s names without the need for a DNS server or
using NetBIOS over T
CP/IP.

o

Improved support for Quality of Service (QoS)
: Ipv6 header fields improve the
identification and handling of network traffic from its source to destination, even when
IPSec encryption is in use.

o

Extensibility
: You can add extension headers after the

Ipv6 packet header, which enable
the inclusion of new features as they are developed in years to come.
