The IESG has approved the following document: - 'Bundle Protocol Version 7' (draft-ietf-dtn-bpbis-31.txt) as Proposed Standard This document is the product of the Delay/Disruption Tolerant Networking Working Group. The IESG contact persons are Martin Duke and Magnus Westerlund. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-dtn-bpbis/ Technical Summary Since the publication of the Bundle Protocol Specification (Experimental RFC 5050) in 2007, the Delay-Tolerant Networking Bundle Protocol has been implemented in multiple programming languages and deployed to a wide variety of computing platforms. This implementation and deployment experience has identified opportunities for making the protocol simpler, more capable, and easier to use. The present document, standardizing the Bundle Protocol (BP), is adapted from RFC 5050 in that context. This document describes version 7 of BP. Delay Tolerant Networking is a network architecture providing communications in and/or through highly stressed environments. Stressed networking environments include those with intermittent connectivity, large and/or variable delays, and high bit error rates. To provide its services, BP may be viewed as sitting at the application layer of some number of constituent networks, forming a store-carry-forward overlay network. Key capabilities of BP include: - Ability to use physical mobility for the movement of data - Ability to move the responsibility for error control from one node to another - Ability to cope with intermittent connectivity, including cases where the sender and receiver are not concurrently present in the network - Ability to take advantage of scheduled, predicted, and opportunistic connectivity, whether bidirectional or unidirectional, in addition to continuous connectivity - Late binding of overlay network endpoint identifiers to underlying constituent network addresses Working Group Summary The document is the core specification for the WG and have received significant review and feedback from the participants. At the end of the process there was quite some discussion around this document obsoleting RFC 5050. Which both required new process between IETF and IRTF stream manager as well as being decided with a rough consensus. Document Quality Multiple interoperable implementations of [RFC5050] have been deployed in significant ongoing experiments for many years. At the time of this writing, the only known implementation of the current document is microPCN (https://upcn.eu/). Personnel Document Shepherd: Fred L.
