A protocol is an agreement between the

communicating parties on how communicationis to proceed.

The glue that holds the whole Internet togetheris the network layer protocol,(Internet

protocol).

The Internet Engineering Task Force (IETF) has developed asuite of protocols and standards known as IP version 6(IPv6).

This new version, previously called IP-The Next Generation(IPng), incorporates the concepts of many proposed methodsfor updating the IPv4 protocol.

The design of IPv6 is intentionally targeted for minimalimpact on upper and lower layer protocols by avoiding the

random addition of new features.

What is IP Version-4.0?IPv4 has proven to be robust, easily implemented and

interoperable, and has stood the test of scaling an internetwork to a global utility the size of today's Internet.

The initial design did not anticipate the following :-

The recent exponential growth of the Internet and theimpending exhaustion of the IPv4 address space.

The growth of the Internet and the ability of Internetbackbone routers to maintain large routing tables.

The need for simpler configuration.

The requirement for security at the IP level.

The need for better support for real-time delivery of dataalso called quality of service (QoS).

The size of an address in IPv6 is 128 bits, which is four times thelarger than an IPv4 address.

A 32-bit address space allows for 232 or 4,294,967,296 possibleaddresses.

A 128-bit address space allows for340,282,366,920,938,463,463,374,607,431,768,211,456 (or3.4*1038) possible addresses.

It is important to remember that the decision to make the IPv6address 128 bits in length was not so that every square meter ofthe Earth could have 6.5*1023 addresses.

The use of 128 bits allows for multiple levels of hierarchy andflexibility in designing hierarchical addressing and routing thatis currently lacking on the IPv4-based Internet.

IPv4 addresses are represented in dotted-decimalformat.

This 32-bit address is divided along 8-bit

boundaries. Each set of 8 bits is converted to itsdecimal equivalent and separated by periods.

For IPv6, the 128-bit address is divided along 16-bitboundaries, and each 16-bit block is converted to a4-digit hexadecimal number and separated bycolons.

Advantages

Same field as in IPV-4 but with different version numbers.

Internet header length Removed in IPv6.

Type of service replaced by the IPv6 Traffic Class field.

Type of service replaced by the IPv6 Payload Length field,which only indicates the size of the payload.

Identification removed in IPv6.

MLD (the replacement for IGMP for IPv4)

Time to Live Replaced by the IPv6 Hop Limit field.

In IPv6, bit-level error detection for the entire IPv6 packet isperformed by the link layer.

Differences

IPv4 IPv6Source and destination

addresses are 32 bits (4

bytes) in length.

Source and destination

addresses are 128 bits (16

bytes) in length.

IPSec support is optional. IPSec support is required.

Header includes a checksum. Header does not include a

checksum.

Fragmentation is supported

at both routers and the

sending host.

Fragmentation is not

supported at routers. It is

only supported at the

sending host.

No identification of packetflow for QoS handling by

routers is present within

the IPv4 header

Packet flow identificationfor QoS handling by routers

is included in the IPv6

header using the Flow Label

field.

ApplicationThe capture and parsing of IPv6 traffic is supported by Microsoft NetworkMonitor, supplied with both Microsoft Systems Management Server (SMS)version 2.0 and Windows 2000 Server.

The Microsoft Research IPv6 Implementation is an IPv6 protocol that runson both Windows NT 4.0 and Windows 2000.

The Microsoft Research IPv6 Implementation runs as a separate protocolcontaining its own versions of Transmission Control Protocol (TCP) andUser Data gram Protocol (UDP).

The Microsoft IPv6 Technology Preview for Windows 2000 is a derivative ofthe Microsoft Research IPv6 Implementation that is intended for applicationdevelopers.

IPv6 Packets are also used in LAN Media.

As its name suggests, the Microsoft IPv6 Technology Preview for Windows2000 can only be installed on a computer running any version of Windows2000 with Service Pack.

ConclusionThis paper discussed the new IPv6 protocol suite by comparing,where possible, the IPv6 protocol suite to similar features orconcepts that currently exist in IPv4. This paper discussed how

IPv6 resolves IPv4 protocol design issues, the new IPv6 headerand extension headers, ICMPv6 (the replacement for ICMP forIPv4), MLD (the replacement for IGMP for IPv4), IPv6 NeighborDiscovery processes that manage interaction betweenneighboring IPv6 nodes, and IPv6 address auto configuration.While not in prevalent use today, the future of the Internet will be

IPv6-based. It is important to gain an understanding of thisstrategic protocol to begin planning for the eventual adoption ofand migration to IPv6.
