A SEMINAR REPORT ON INTERPLANTERY INTERNET
INTRODUCTION CCSDS (CONSULTATIVE COMMITTEE FOR SPACE DATA SYSTEM) NASA (NATIONAL AERONAUTICS AND SPACE ADMINISTRATION) DSN (DEEP SPACE NETWORK) PROTOCOLS FOR MARS EXPLORATION
PRELIMINARY CONSIDERATION • TCP/IP NOT WORK AT INTERPLANATORY DISTANCE DUE TO DELAY • WHAT IS COMMUNICATION CHANNEL • REQUIREMENT OF IPN BACKBONE • SCHEDULING OF RESOURCE REQUIRED “TIME-SYNCHRONIZATION”
IPN OPERATING ENVIRONMENT • DIFFERENCE OF IPN AND TERRESTRIAL COMMUNICATION • DELAY • LOW AND ASSYMETRY OF BANDWITH • HIGH BIT ERROR RATE • INTERMITANT CONNECTIVITY
BANDWITH FOR IPN IS MODEST COMPARE TO TERRESTRIAL COMM. • DIFFICULTY TO GENERATE POWER CAUSE HIGH BIT ERROR RATE • IPN WILL IN NEAR FEATURE BE KNOWN AS INTERMITANT CONNECTIVITY BETWEEN PLANET
NAME CONTAINS ADMINISTRATIVE & ROUTING PART • DNS ( DOMAIN NAME SYSTEM ) NAME INTO NUMERIC ADDRESS 1 ZONE TRANSFER TECHNIQUE 2 TOP LAVEL DOMAIN “.SOL”TRANSFER TECHNIQUE
ROUTING PART IDENTIFIED PARTICULAR INTERNET • NAME {ADMINISTRATIVE , ROUTING} • ROUTING ANY IPN NODE • ADMINISTRATIVE ADDRES IN IPN NODE • EX. { WWW.IPNSIG.ORG , EARTH.SOL }
BUNDLE LAYER TERMINATES LOCAL TRANSPORT PROTOCOLS • STORE – AND – FORWORD MICHANISM • SCHEDULE OF NODES • INTRUPT TRAFFIC • DATA HOLD AT HIGER LAYER • TO TERMINATE LOCAL TRANSPORT PROTOCOLS
INFORMATION CARRIED BY BUNDLE LAYER • BUNDLE IDENTIFIER • REMOTE ENTITY NAME • SOURCE ENTITY NAME • AUTHANTICATION INFORMATION • SIZE OF DATA • TIME – TO – LIVE
TO TRANSFER DATA FROM EARTH MARS 1BUNDLE CREATION AND FIRST HOPE DESTINATION 2BUNDLE PROCESSING AT FIRST HOPE DESTINATION { IPNGW1.JPL.NASA.GOV , EARTH.SOL } 3BUNDLE FROM G\W TO DESTINATION IPN REGION { IPNGW2.NASA.MARE.ORG , MARS.SOL } 4BUNDLE PROCESSING AT DESTINATION
SECURITY IN IPN • ASSUMPSION REGARDING REQUIRED IPN SECURITY MECHANISM. • SECURE E-MAIL TECHNOLOGY. • APPLICATION OF SECURE E-MAIL TECH TO THE IPN. • PROTECTING IPN DATA & IPN INFRASTRUCTURE.
ASSUMPTION REGARDING REQUIRED IPN SECURITY MECHNISM • ACCESS CONTROL. • AUTHENTICATION. • DATA INTEGRATY. • DATA PRIVACY. TWO SECURITY PARADIGM. • HOP BY HOP PARADIGM. • END TO END PARADIGM.
SECURE E-MAIL TECHNOLOGY • USE OF PUBLIC KEY CRYPTOGRAPHY. SOME PROBLEM • QUITE CONSUMPTIVE OF PROCESSOR POWER • CONSUMPTIVE AS A BANDWIDTH
APPLICATION OF SECURE E-MAIL TECH.TO IPN • THE MASSEGE CONTENTS ARE “CONTAINERISED”. • BODY PART CONTAIN ENCRYPTED SYMMETRIC KEY & INFO. NEEDED FOR ENCRYPTION. • CERTIFICATES CONTAIN DIGITAL SIGNED PUBLIC KEY.
PROTECTING IPN DATA AND INFRASTRUCTURE • VARIOUS INFRASTRUCTURE INFO. NEED TO PROTECTION. • BUNDLE AGENT MIGHT ENCRYPT FOR HOP-BY-HOP SECURITY PROTECTION.
BUILDING A STABLE BACKBONE FOR IPN • BACKBONE – A SET OF HIGH CAPACITY, HIGH AVAILABILITY LINK BETWEEN POINT OF ACCESS TO HIGH ACTIVITY SUBNETS. IPNTERRESTRIAL • MEDIA OF RF OR COPER WIRE OR TRANSMISSION OPTICAL OPTICAL FIBER • NATURE OF OPERATIONAL, STRUCTURAL & CONNECTIVITY DIRECTLY,DYNAMIC STATIC • COST HIGHER LOWER
BACKBONE DESIGN CONSIDERATION • BANDWIDTH IS NOT FREE OR EVEN CHEAP. • INTERACTIVE PROTOCOL DON’T WORK AT LEAST NOT WELL. • LONG HOUL PROTOCOL & BUNDLE PROTOCOL. • OPERATE CLOCK SYNCHRONISATION.
CONCLUSION • WE NEED TO USE A “PONY-EXPRESS” MODEL. • CURRENT ADVANCE LIKE MOBILE IP,SCPC,RDI & THEIR ENVIRONMENT WILL USE IN THESE ENVIRONMENT.
