Among the challenges to be addressed are: extremely large delay for transmissions up to tens of Astronomical Units in size; severe asymmetry in the transmission capacity of bidirectional channels linking two communicating platforms; severe variation in interference experienced on the channel(s) - e.g. solar storms; episodic loss of connectivity owing to celestial motions of the platforms and the planets/satellites/asteroids with which they are associated.
Adapting the existing or projected Earth Internet architecture to Interplanetary scale is a significant challenge however, it is also highly speculative and not yet mature enough to merit focused IETF attention as a whole.
The primary focus of these efforts is:
As progress on topics matures, the IPNRG may submit proposals for work items with existing IETF working groups where applicable or recommend to the IETF that a topic be advanced into a BOF and/or working group.
The group will report its progress through a publicly accessible Web site and hold at least one open meeting per year.
As the scope of this working group necessarily overlaps with that of previously established IRTF and IETF working groups, as study items mature this group will coordinate activities with its peer entities whenever possible. For example, the E2E Research Group has dealt with some of the problems of high delay X bandwidth products for protocols such as TCP.
This group will have a diverse, though limited core membership; From time to time it will be necessary to expand the group to form broader study teams in order to address specific topics. In order to solicit information from, and supply information to, the Internet community at large, the group will hold at least one open meeting per year and will have a publicly available web site and mailing list. Membership to this group will be granted by invitation by the chair(s).
IPNRG meets at least 2-3 times a year, at times and locations specific to the group rather than in coordination with other activities, and the rest of the year, work is expected to progress through online interaction.
