What does IPN mean?
Interplanetary Internet Services.
A communication system to provide Internet-like services across interplanetary distances in support of deep space exploration.
It is a “Network of Internets”.
It is a new technology that will extend the need of terrestrial internet into space
The current terrestrial Internet and its technology provide a robust basis to IPN
Where IPN will be used?
It will be used to send & receive emails and data to different planets in outer space.
To communicate with spacecraft using bi-directional radio links so as to be able to send instructions, and to get data back to earth.
It will help in more exploration of solar system.
It will increase the intelligence of human about solar system.


Desiderata of IPN
Go thoughtfully in the knowledge that all interplanetary communication derives from the modulation of radiated energy.
Sometimes a planet will be between the source and the destination.
Therefore no end-to-end connectivity at any time and no relay chatting is possible.
Signal strength drop off by the square of the distance, and there is a lot of distance.
We also need to deal with security issues in the IPN. .
Challenges in IPN
Size, weight and power are the main challenges.
Power limitation may cause asymmetries in data transmission eg. Data rate of earth to mars can be 1 Kilobits/sec and that is of from mars to earth can be 100 Kilobits/sec.
Scheduling of resources is required so that at proper time proper resources should be available to send and receive data to planet and from planet.
IPN operating environment elays:- Scheduling, queuing delay and require special equipments.
Current deep space mission operate with high bit errors due to difficulties in generating power.

What will be change in domain name?
In Simple internet we use Administrative DNS that is converted into IP address and is used for reference in whole network. And for that we use large data base and it’s not possible in case of IPN because of being distributed data base.
But in IPN our DNS will be having two parts :-{Administrative Part, Routing Part}
Administrative Part will be same as that of simple internet and to search out about this will be responsibility of IPN REGION but routing part will specify rout through which data is to be transmitted.
