1. LISP for Satellite Networks
Publication URL: https://datatracker.ietf.org/doc/html/draft-farinacci-lisp-satellite-network/

2. Considerations for Benchmarking Network Performance in Satellite Internet Constellations
Publication URL: https://datatracker.ietf.org/doc/html/draft-lai-bmwg-sic-benchmarking/
This draft describes our basic considerations as specifications to guide the network performance benchmark for SICs. A satellite network constructed upon emerging SICs in low earth orbit has many unique characteristics as compared to existing terrestrial networks. Specifically, our considerations include multiple networking models of emerging SICs, a data-driven benchmarking approach which may enable testers to build a laboratory benchmark environment with acceptable flexibility and fidelity to support various experiments, critical configuration parameters that might affect the SIC network performance, and several suggested test cases for network performance benchmarking.
3. Problems and Requirements of Satellite Constellation for Internet
Publication URL: https://datatracker.ietf.org/doc/html/draft-lhan-problems-requirements-satellite-net/
This document presents the detailed analysis about the problems and requirements of satellite constellation used for Internet. It starts from the satellite orbit basics, coverage calculation, then it estimates the time constraints for the communications between satellite and ground-station, also between satellites. How to use satellite constellation for Internet is discussed in detail including the satellite relay and satellite networking. The problems and requirements of using traditional network technology for satellite network integrating with Internet are finally outlined.
4. Semantic Address Based Instructive Routing for Satellite Network
Publication URL: https://datatracker.ietf.org/doc/html/draft-lhan-satellite-instructive-routing/
This document presents a method to do IP routing over satellite network that consists of LEO (Low Earth Orbit) satellites and ground-stations. The method uses the source routing mechanism. The whole routing info is obtained by path calculation. The routing path information is converted to be a list of instructions and embedded into user packet’s IPv6 extension header. At each hop or each satellite, the routing process engine will forward the packet based on the specified instruction for the satellite. Until the packet reaches the edge of satellite network, or the last satellite, the packet will be sent to a ground station.
5. Satellite Semantic Addressing for Satellite Constellation
Publication URL: https://datatracker.ietf.org/doc/html/draft-lhan-satellite-semantic-addressing/
This document presents a semantic addressing method for satellites in satellite constellation connecting with Internet. The satellite semantic address can indicate the relative position of satellites in a constellation. The address can be used with traditional IP address or MAC address or used independently for IP routing and switching.
6. Routing and Addressing Challenges Introduced by New Satellite Constellations
Publication URL: https://datatracker.ietf.org/doc/html/draft-kw-rtgwg-satellite-rtg-add-challanges/
This document summerises near-to-mid-term space-networking problems; it outlines the key components, challenges, and requirements for integrating future space-based network infrastructure with existing networks and mechanisms. Furthermore, this document highlights the network control and transport interconnection, and identify the resources and functions required for successful interconnection of space-based and Earth-based Internet infrastructure.
7. Problems and Requirements of Addressing in Integrated Space-Terrestrial Network
Publication URL: https://datatracker.ietf.org/doc/html/draft-li-istn-addressing-requirement/
This document presents a detailed analysis of the problems and requirements of network addressing in “Internet in space” for terrestrial users. It introduces the basics of satellite mega- constellations, terrestrial terminals/ground stations, and their inter-networking. Then it explicitly analyzes how space-terrestrial mobility yeilds challenges for the logical topology, addressing, and their impact on routing. The requirements of addressing in the space-terrestrial network are discussed in detail, including uniqueness, stability, locality, scalability, efficiency and backward compatibility with terrestrial Internet. The problems and requirements of network addressing in space-terrestrial networks are finally outlined.
8. Problems and Requirements of Source Address Spoofing in Integrated Space and Terrestrial Networks
Publication URL: https://datatracker.ietf.org/doc/html/draft-jliu-istn-savi-requirement/
This document presents the detailed analysis about the problems and requirements of dealing with the threat of source address spoofing in Integrated Space and Terrestrial Networks (ISTN). First, characteristics of ISTN that cause DDos are identified. Secondly, it analyzes the major reasons why existing terrestrial source address validation mechanism does not fit well for ISTN. Then, it outlines the major requirements for improvement on source address validation mechanism for ISTN.
9. Enhancing Transport Protocols over Satellite Networks
Publication URL: https://datatracker.ietf.org/doc/html/draft-jones-tsvwg-transport-for-satellite/
This document follows the terminology proposed in [I-D.irtf-panrg-path-properties] to describe the current characterises of common satellite paths. This document also describes considerations when implementing and deploying reliable transport protocols that are intended to work efficiently over paths that include a satellite system. It discusses available network mitigations and offers advice to designers of protocols and operators of satellite networks.
10. Network Coding for Satellite Systems
Publication URL: https://datatracker.ietf.org/doc/html/rfc8975/
This document is a product of the Coding for Efficient Network Communications Research Group (NWCRG). It conforms to the directions found in the NWCRG taxonomy (RFC 8406). The objective is to contribute to a larger deployment of Network Coding techniques in and above the network layer in satellite communication systems. This document also identifies open research issues related to the deployment of Network Coding in satellite communication systems.
11. Time Variant Routing Problem Statement
Publication URL: https://datatracker.ietf.org/doc/html/draft-taylor-tvr-prb-stmt/
This document attempts to describe the problems perceived with existing routing protocols and act as a “Problem Statement” to be addressed by the proposed Time-Variant Routing (TVR) working group.
12. TVR (Time-Variant Routing) Use Cases
Publication URL: https://datatracker.ietf.org/doc/html/draft-birrane-tvr-use-cases/
This document introduces use cases where TVR computations could improve message exchange in a network.
13. DTN Management Architecture
Publication URL: https://datatracker.ietf.org/doc/html/draft-ietf-dtn-dtnma/
This document describes a DTN management architecture (DTNMA) suitable for managing devices in any challenged environment but, in particular, those communicating using the DTN Bundle Protocol (BPv7). Operating using BPv7 require that the architecture not presume any synchronized transport behavior. This means that the DTNMA cannot operate as a query-response system across the network. This allows implementations compliant with the DTNMA to operate in extremely challenging conditions, such as over uni-directional links and other places where BPv7 is the preferred transport.
14. Bundle Protocol Version 7
Publication URL: https://datatracker.ietf.org/doc/html/rfc9171/
This document presents a specification for the Bundle Protocol, adapted from the experimental Bundle Protocol specification developed by the Delay-Tolerant Networking Research Group of the Internet Research Task Force and documented in RFC 5050.
15. Delay-Tolerant Networking TCP Convergence-Layer Protocol Version 4
Publication URL: https://datatracker.ietf.org/doc/html/rfc9174/
This document describes a TCP convergence layer (TCPCL) for Delay- Tolerant Networking (DTN). This version of the TCPCL protocol resolves implementation issues in the earlier TCPCL version 3 as defined in RFC 7242 and provides updates to the Bundle Protocol (BP) contents, encodings, and convergence-layer requirements in BP version 7 (BPv7). Specifically, TCPCLv4 uses BPv7 bundles encoded by the Concise Binary Object Representation (CBOR) as its service data unit being transported and provides a reliable transport of such bundles. This TCPCL version also includes security and extensibility mechanisms.
