A new Request for Comments is now available in online RFC libraries. RFC 8182 Title: The RPKI Repository Delta Protocol (RRDP) Author: T. Bruijnzeels, O. Muravskiy, B. Weber, R. Austein Status: Standards Track Stream: IETF Date: July 2017 Mailbox: tim@ripe.net, oleg@ripe.net, bryan@cobenian.com, sra@hactrn.net Pages: 24 Characters: 52486 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-ietf-sidr-delta-protocol-08.txt URL: https://www.rfc-editor.org/info/rfc8182 DOI: 10.17487/RFC8182 In the Resource Public Key Infrastructure (RPKI), Certificate Authorities (CAs) publish certificates, including end-entity certificates, Certificate Revocation Lists (CRLs), and RPKI signed objects to repositories. Relying Parties retrieve the published information from those repositories. This document specifies a new RPKI Repository Delta Protocol (RRDP) for this purpose. RRDP was specifically designed for scaling. It relies on an Update Notification File which lists the current Snapshot and Delta Files that can be retrieved using HTTPS (HTTP over Transport Layer Security (TLS)), and it enables the use of Content Distribution Networks (CDNs) or other caching infrastructures for the retrieval of these files. This document is a product of the Secure Inter-Domain Routing Working Group of the IETF. This is now a Proposed Standard. STANDARDS TRACK: This document specifies an Internet Standards Track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the Official Internet Protocol Standards (https://www.rfc-editor.org/standards) for the standardization state and status of this protocol.
