Removed IPv6 Header Comparison with IPv4 bit 0 bit 0 8 16 24 31 4 12 16 24 31 Version Class Flow Label IHL Service Type Total Length Version Identifier Flags Fragment Offset Next Header Payload Length Hop Limit Time to Live Protocol Header Checksum 32 bit Source Address 128 bit Source Address 32 bit Destination Address Options and Padding IPv4 Header 20 octets, 12 fields, including 3 banner bits + altered max number of choices 128 bit Destination Address Changed IPv6 Header 40 octets, 8 fields + Unlimited Chained Extension (choices) Header June 2003 Page 9

Slide 10

Design Philosophy Learning as a matter of fact Recognizable yet streamlined header configuration Reduce basic case preparing expense of bundle taking care of Keep transmission capacity overhead low regardless of expanded size of the location Flexible and extensible backing for alternative headers IP choices have been moved to an arrangement of discretionary Extension Headers Extension Headers are affixed together June 2003 Page 10

Slide 11

IPv6 Header Performance Wins Layout Fixed Size IPv6 Header Fewer fields in essential header speedier handling of fundamental parcels 64 Bit Alignment Header/Options Efficient choice preparing Option fields handled just when present Options not restricted at 40 bytes Processing of most choices constrained performed just at destination June 2003 Page 11

Slide 12

IPv6 Header Performance Wins Processing Remove checksum from Network Layer Datalinks are more dependable nowadays Upper Layer checksums are currently compulsory (for instance, TCP, UDP, ICMPv6) No discontinuity in the system Reduce load on switches Easier to actualize in equipment Easy for Layer 3 exchanging of IP June 2003 Page 12

Slide 13

Link-Local Global Site-Local Addressing Model (RFC 2373) Many sorts of Address No change from IPv4 model Addresses alloted to Interfaces have different locations IPv6 locations have degree and lifetime June 2003 Page 13

Slide 14

IPv6 Unicast Address = prefix of n bits + interface ID of 128-n bits Separate “who you are” from “where you are joined to” Aggregatable Global Unicast Address position 128-n bits n bits prefix Interface ID Prefix Representation <prefix>::/<n-bits> 3FFE:0301:DEC1:: 0A00:2BFF:FE36:701E June 2003 Page 14

Slide 15

With NAT (IPv4): Need to learn IP address “outside the NAT” Need to give that deliver to peer third gathering enrollment servers could be expected to discover associates Because NAT changes the IP address, IPSec won\'t work With IPv6 Just utilize the IPv6 address IPSec in IPv6: It’s obligatory Provides end-to-end security Authentication Encryption Peer-to-Peer Apps: Instant informing Interactive amusements VoIP IPv6 Advantage Restoration of End-to-End Model June 2003 Page 15

Slide 16

IPv6 Advantage Automatic Connectivity Provides Network Stateless and Stateful attachment and-play Link Local Address (No switch or server obliged) Stateless instrument - Router commercials give prefix Stateful component - Server gives address (DHCP) Simplified Network Administration Lower system upkeep Easy Renumbering Designed to happen! Enhanced Competition and a n end of ISP “lock in”! June 2003 Page 16

Slide 17

IPv6 Advantage Improved Mobile IP support IPv6 Mobility depends on center elements of IPv6 is intended to bolster Mobility is not a “Add-on” highlights No single purpose of disappointment More Scalable : Better Performance June 2003 Page 17

Slide 18

IPv6 Advantage Mandates IP Security elements are institutionalized and ordered All executions must offer them Extensions to the IP convention suite Operates at the IP layer Invisible to applications Protects all upper layer conventions June 2003 Page 18

Slide 19

IPv6 Advantage Inbuilt Quality of Service Support for DiffServ (Differentiated Service) Class field empowers a source to distinguish craved class of administration/conveyance need of its parcels Correspond to Type-Of-Service in IPv4 Support for IntServ (Integrated Service) Enable a source to recognize streams requiring extraordinary QoS Flow is a grouping of bundles which require unique taking care of Not completely characterized yet June 2003 Page 19

Slide 20

IPv6 Advantage Simple IPv4/IPv6 Interoperations Many answers for convey IPv6 administrations One size does not fit every Many instrument Dual IP layer Tunnels Configured, programmed, 6to4, ISATAP, Teredo DSTM Protocol Translation June 2003 Page 20

Slide 21

Facts: Millions of hubs are running IPv4 today Some hubs will never move up to IPv6 Large interest in IPv4 applications Consequences: IPv4 and IPv6 will exist together for an amplified period Transition ought to forestall confinement of IPv4 hubs No interruption - no Flag Day IPv6 and IPv4 switches and hosts can interoperate No Dependencies - Incremental update and organization IPv6 switches and hosts can be sent in an exceptionally diffused and incremental form Low start-up expenses Make move as simple as could be expected under the circumstances for end-clients, framework executives, and system administrators IPv6 Deployment - Facts Keys to Deploying IPv6 Successfully June 2003 Page 21

Slide 22

Analyze your foundation Obtain addresses Your IPv6 Internet Service Provider will assign a piece of location space Pick proper arrangement situation Routing/subnet design DNS Network Management And then arrangement for hosts ….. Expect most frameworks will be programming upgradeable Beware of IPv4 usage in equipment Ask your sellers about their IPv6 arranges before purchasing new equipment New and altered programming IP stack, DNS, DHCP, directing conventions Transparent for end clients Network Administrator Quite a long way to go, however much has a commonplace vibe Practical Aspects of IPv6 Deployment June 2003 Page 22
