INTERNET PROTOCOL VERSION 6 : 

INTERNET PROTOCOL VERSION 6 SOURABH S. AGGARWAL 6TH I.T. ROLL NO. 1

INTRODUCTION : 

INTRODUCTION PROTOCOL : SET OF RULES PRESENT PROTOCOL IPV4 BOTTLENECKING,CONGESTION,LESS ADDRESS SPACE IPV6 WITH INTERNET2 AND QoS WHAT’S IPV6? WHY IPV6? WHY DO I NEED IPV6?

KEY FEATURES : 

KEY FEATURES IPV6 AS A RE-ENGINEERING EFFORT AGAINST IP TECHNOLOGY LARGER IP ADDRESS SPACE DEPLOY MORE RECENT TECHNOLOGIES

DEPLOY MORE RECENT TECHNOLOGIES : 

DEPLOY MORE RECENT TECHNOLOGIES AUTO CONFIGURATION SECURITY FRIENDLY TO TRAFFIC ENGINEERING MULTICAST BETTER SUPPORT FOR AD-HOC NETWORKING A CURE TO ROUTING TABLE GROWTH SIMPLIFIED HEADER STRUCTURE ALLOWS FLEXIBLE PROTOCOL EXTENSIONS SMOOTHEN TRANSITION FROM IPV4 FOLLOWS KEY DESIGN PRINCILES OF IPV4

OBJECTIVES : 

OBJECTIVES CONTINUE TO PROMOTE IPV6 FOCUS ON MOBILE IPV6, IPV6 NETWORKING,QoS DEVELOP,TEST AND VALIDATE IPV6 SEEK COOPERATION

IPV6 ADDRESSING : 

IPV6 ADDRESSING 128 BITS LENGTH ADDRESS SPACING POSSIBLE ADDRESSES 340282366920938463463374607431768211456 THREE HUNDRED FORTY UNDECILLION IPV4 SUPPOTS 4 BILLION NODES 64 BIT NETWORK PREFIX AND 64 BIT HOST ADDRESS

NOTATION FOR IPV6 ADDRESSES : 

NOTATION FOR IPV6 ADDRESSES 3ffe:6a88:85a3:08d3:1319:8a2e:0370:7344 IF 3ffe:6a88:85a3:0000:1319:8a2e:0370:7344 THEN 3ffe:6a88:85a3::1319:8a2e:0370:7344 HERE 2001:2353:0000:0000:0000:0000:1428:57ab 2001:2353:0000:0000:0000::1428:57ab 2001:2353:0:0:0:0:1428:57ab 2001:2353:0::0:1428:57ab 2001:2353:1428:57ab ARE VALID BUT 2001:2353::cad6 IS INVALID

IPV4 ADDRESS IN IPV6 : 

IPV4 ADDRESS IN IPV6 ::ffff:192.168.89.9 IS SAME AS ::ffff:c0a8:5909 IS NOT SAME AS ::192.168.89.9 OR ::c0a8:5909 135.75.43.52 CAN BE CONVERTED TO 0000:0000:0000:0000:0000:0000:374B:2B34 OR ::374B:2B34

IPV6 HEADER : 

IPV6 HEADER

IPV6 AND IPV4 HEADERS : 

IPV6 AND IPV4 HEADERS IPV4 HEADER IPV6 HEADER

IPV6 EXTENSION HEADER : 

IPV6 EXTENSION HEADER HOP- BY-HOP ROUTING FRAGMENT DESTINATION OPTIONS AUTHENTICATION ESP

SECURITY IN IPV6 : 

SECURITY IN IPV6 AUTHENTICATION HEADER

ENCAPSULATING SECURITY PAYLOAD HEADER : 

ENCAPSULATING SECURITY PAYLOAD HEADER

MOBILE IP : 

MOBILE IP

MOBILE IPV4 AND IPV6 : 

MOBILE IPV4 AND IPV6 TRIANGULAR ROUTING DEPLOYMENT PROBLEM INGRESS FILTERING AUTHENTICATION ROUTER ADVERTISEMENT SOLICITATION ADDRESS AUTO- CONFIGURATION NEIGHBOR DISCOVERY IPV4 IPV6

MOBILE IPV6 IN GPRS/WCDMA : 

MOBILE IPV6 IN GPRS/WCDMA MOBILE IPV6 FOR INTER-PLMN MOBILITY THE BASIC OPERATION IN GPRS/WCDMA

MOBILE IPV6 IN 2G AND 3G NETWROKS : 

MOBILE IPV6 IN 2G AND 3G NETWROKS THIS REQUIRES INSTALLING A HOME AGENT CAN BE LOCATED IN OWN OR SOME OTHER NETWORK FEASIBLE IN OPERATORS EDGE ROUTER

MIGRATION FROM 6 TO 4 NEWORK : 

MIGRATION FROM 6 TO 4 NEWORK IPV6 WITHOUT ANY GLOBAL IPV6 PREFIX NO MANUAL CONFIGURATION FOR ISATAP

IPV6 TUNELLING OVER IPV4 : 

IPV6 TUNELLING OVER IPV4

IPV6 IN MOBILE PACKET NETWORKS : 

IPV6 IN MOBILE PACKET NETWORKS PACKET SWITCHING AIDED CAUSE NEW NETWORK IS EASILY FOUND ON FAILURE SECURITY INCREASED ON USING GLOBALLY 3GPP USED IN IM CN DOMAIN THIS DOMIAN WILL PROCESS IN FUTURE 3G NEWORKS

PACKET SIZE ISSUES : 

PACKET SIZE ISSUES IPV6 REQUIRES 1280 OCTET PACKET OR GREATER RECOMMENDED 1500 OCTET PACKET IPV6 FRAGMENT HEADER TO SEND LARGER THAN MTU PACKET IT IS USED FROM IPV6 TO IPV4 TOTAL OF 1232 i.e. 1280 – 40 FOR FRAGMENT HEADER

ADVANTAGES OVER IPV4 : 

ADVANTAGES OVER IPV4 SCALABILITY SECURITY CONSIDERATION TO REALTIMENESS PLUG AND PLAY CLEARER SPECIFICATION AND OPTIMIZATION

DIFFICULTIES : 

DIFFICULTIES INCOMPATIBILITY INCOHERENCE DISTRACTIONS

INTERNET2 AND IPV6 : 

INTERNET2 AND IPV6 1.1 TB OF DATA IN LESS THAN 30 MINUTES LARGE BANDWIDTH FACILITY NEEDS LARGE ADDRESSES ALSO HAND IN HAND DEVELOPMENT

QoS AND IPV6 : 

QoS AND IPV6 COMPROMISE WITH INTERNET SERVICE QUALITY SATELLITE QUALITY TRANSMISSION AND RECEPTION

CONCLUSION : 

CONCLUSION EASY CONFIG,LARGER ADDRESS BITS,QoS BOON FOR COUNTRIES LIKE INDIA AND CHINA NEEDS ABOUT 4 TO 5 YEARS TO COMMERCIALIZE BOTH WILL COEXIST FOR YEARS OF TRANSITION. FUTURE IS VERY BRIGHT
