- SRv6 BGP based Overlay services (draft-ietf-bess-srv6-services)
By Gaurav Dawra, Clarence Filsfils, Patrice Brissette, Swadesh Agrawal, John Leddy, daniel.voyer@bell.ca, daniel.bernier@bell.ca, Dirk Steinberg, Robert Raszuk, Bruno Decraene, Satoru Matsushima, Shunwan Zhuang, Jorge Rabadan, 2019-10-16 TXT HTML PDF
Abstract: This draft defines procedures and messages for SRv6-based BGP services including L3VPN, EVPN and Internet services. It builds on RFC4364 "BGP/MPLS IP Virtual Private Networks (VPNs)" and RFC7432 "BGP MPLS-Based Ethernet VPN".
- Using Multicast DNS to protect privacy when exposing ICE candidates (draft-ietf-rtcweb-mdns-ice-candidates)
By Youenn Fablet, Jeroen Borst, Justin Uberti, Qingsi Wang, 2019-10-16 TXT HTML PDF
Abstract: WebRTC applications collect ICE candidates as part of the process of creating peer-to-peer connections. To maximize the probability of a direct peer-to-peer connection, client private IP addresses are included in this candidate collection. However, disclosure of these addresses has privacy implications. This document describes a way to share local IP addresses with other clients while preserving client privacy. This is achieved by concealing IP addresses with dynamically generated Multicast DNS (mDNS) names.

- Segment Routing for Enhanced VPN Service (draft-dong-spring-sr-for-enhanced-vpn)
By Jie Dong, Stewart Bryant, Takuya Miyasaka, Yongqing Zhu, Fengwei Qin, Zhenqiang Li, 2019-10-16 TXT HTML PDF
Abstract: Enhanced VPN (VPN+) is an enhancement to VPN services to enable it to support the needs of new applications, particularly applications that are associated with 5G services. These applications require better isolation from both control and data plane's perspective and have more stringent performance requirements than can be provided with overlay VPNs. The characteristics of an enhanced VPN as perceived by its tenant needs to be comparable to those of a dedicated private network. This requires tight integration between the overlay VPN and the underlay network topology and resources in a scalable manner. An enhanced VPN may form the underpinning of 5G network slicing, but will also be of use in its own right. This document describes how to use segment routing based mechanisms to provide the enhanced VPN service with the required network topology and resources. The overall mechanism of providing segment routing based enhanced VPN service is also described. The proposed mechanism is applicable to both segment routing with MPLS data plane (SR-MPLS) and segment routing with IPv6 data plane (SRv6).
- MVPN and MSDP SA Interoperation (draft-ietf-bess-mvpn-msdp-sa-interoperation)
By Zhaohui Zhang, Leonard Giuliano, 2019-10-16 TXT HTML PDF
Abstract: This document specifies the procedures for interoperation between Multicast Virtual Private Network (MVPN) Source Active routes and customer Multicast Source Discovery Protocol (MSDP) Source Active routes, which is useful for MVPN provider networks offering services to customers with an existing MSDP infrastructure. Without the procedures described in this document, VPN-specific MSDP sessions are required among the PEs that are customer MSDP peers. This document updates RFC6514.

- DNS Privacy Considerations (draft-ietf-dprive-rfc7626-bis)
By Stephane Bortzmeyer, Sara Dickinson, 2019-10-16 TXT HTML PDF
Abstract: This document describes the privacy issues associated with the use of the DNS by Internet users. It is intended to be an analysis of the present situation and does not prescribe solutions. This document obsoletes RFC 7626.
- Delay-Tolerant Networking TCP Convergence Layer Protocol Version 4 (draft-ietf-dtn-tcpclv4)
By Brian Sipos, Michael Demmer, Joerg Ott, Simon Perreault, 2019-10-16 TXT HTML PDF
Abstract: This document describes a revised protocol for the TCP-based convergence layer (TCPCL) for Delay-Tolerant Networking (DTN). The protocol revision is based on implementation issues in the original TCPCL Version 3 of RFC7242 and updates to the Bundle Protocol contents, encodings, and convergence layer requirements in Bundle Protocol Version 7. Specifically, the TCPCLv4 uses CBOR-encoded BPv7 bundles as its service data unit being transported and provides a reliable transport of such bundles. Several new IANA registries are defined for TCPCLv4 which define some behaviors inherited from TCPCLv3 but with updated encodings and/or semantics.
- Extended BGP Administrative Shutdown Communication (draft-ietf-idr-rfc8203bis)
By Job Snijders, Jakob Heitz, John Scudder, Alexander Azimov, 2019-10-16 TXT HTML PDF
Abstract: This document enhances the BGP Cease NOTIFICATION message "Administrative Shutdown" and "Administrative Reset" subcodes for operators to transmit a short freeform message to describe why a BGP session was shutdown or reset. This document updates RFC 4486 and obsoletes RFC 8203 by defining an Extended BGP Administrative Shutdown Communication to improve communication using multibyte character sets.
- Implicit IV for Counter-based Ciphers in Encapsulating Security Payload (ESP) (draft-ietf-ipsecme-implicit-iv)
By Daniel Migault, Tobias Guggemos, Yoav Nir, 2019-10-16 TXT HTML PDF
Abstract: Encapsulating Security Payload (ESP) sends an initialization vector (IV) in each packet. The size of IV depends on the applied transform, being usually 8 or 16 octets for the transforms defined by the time this document is written. Some algorithms such as AES-GCM, AES-CCM and ChaCha20-Poly1305 when used with IPsec, take the IV to generate a nonce that is used as an input parameter for encrypting and decrypting. These algorithms require a unique IV but do not require an unpredictable IV. As a result, the value provided in the ESP Sequence Number (SN) can be used instead to generate the nonce. This avoids sending the IV itself, and saves in the case of AES-GCM, AES-CCM and ChaCha20-Poly1305 8 octets per packet. This document describes how to do this.
- Hierarchical HITs for HIPv2 (draft-moskowitz-hip-hierarchical-hit)
By Robert Moskowitz, Stuart Card, Adam Wiethuechter, 2019-10-16 TXT HTML PDF
Abstract: This document describes using a hierarchical HIT to facilitate large deployments of managed devices. Hierarchical HITs differ from HIPv2 flat HITs by only using 64 bits for mapping the Host Identity, freeing 32 bits to bind in a hierarchy of Registering Entities that provide services to the consumers of hierarchical HITs.
- Subscription to Multiple Stream Originators (draft-zhou-netconf-multi-stream-originators)
By Tianran Zhou, Guangying Zheng, Eric Voit, Alexander Clemm, Andy Bierman, 2019-10-16 TXT HTML PDF
Abstract: This document describes the distributed data export mechanism that allows multiple data streams to be managed using a single subscription. Specifically, multiple data streams are pushed directly to the collector without passing through a broker for internal consolidation.

- Additional Units for SenML (draft-ietf-core-senml-more-units): Publication Requested » In Last Call
By Carsten Bormann, 2019-10-12 TXT HTML PDF
Abstract: The Sensor Measurement Lists (SenML) media type supports the indication of units for a quantity represented. This short document registers a number of additional unit names in the IANA registry for Units in SenML. It also defines a registry for secondary units that cannot be in SenML's main registry as they are derived by linear transformation from units already in that registry; RFC 8428 is updated to also accept these units.

By Andy Bierman, Martin Bjorklund, Kent Watsen, 2019-07-15 TXT HTML PDF
