- Generic Fault-avoidance Routing Protocol for Data Center Networks (draft-sl-rtgwg-far-dcn)
By Bin Liu, Yantao Sun, Jing Cheng, Yichen Zhang, Bhumip Khasnabish, 2019-05-23 TXT HTML PDF
Abstract: This draft proposes a generic routing method and protocol for a regular data center network, named as fault-avoidance routing (FAR) protocol. FAR protocol provides a generic routing method for all types of regular topology network architectures that are proposed for large-scale cloud-based data centers over the past few years. FAR protocol is well designed to fully leverage the regularity in the topology and compute its routing table in a simplistic manner. Fat- tree is taken as an example architecture to illustrate how FAR protocol can be applied in real operational scenarios.

First, this document explains use cases using V2V, V2I, and V2X networking. Next, it makes a problem statement about key aspects in IP-based vehicular networking, such as IPv6 Neighbor Discovery, Mobility Management, and Security & Privacy. For each key aspect, this document specifies requirements in IP-based vehicular networking, and suggests the direction of solutions satisfying those requirements.
- LPWAN Static Context Header Compression (SCHC) for CoAP (draft-ietf-lpwan-coap-static-context-hc)
By Ana Minaburo, Laurent Toutain, Ricardo Andreasen, 2019-05-24 TXT HTML PDF
Abstract: This draft defines the way SCHC header compression can be applied to CoAP headers. The CoAP header structure differs from IPv6 and UDP protocols since CoAP uses a flexible header with a variable number of options themselves of variable length. The CoAP protocol is asymmetric in its message format, the format of the header packet in the request messages is different from that in the response messages. Most of the compression mechanisms have been introduced in [I-D.ietf-lpwan-ipv6-static-context-hc], this document explains how to use the SCHC compression for CoAP.
- RFC8287 Sub-TLV Length Clarification (draft-ietf-mpls-rfc8287-len-clarification)
By Nagendra Kumar, Carlos Pignataro, Faisal Iqbal, Sasha Vainshtein, 2019-05-25 TXT HTML PDF
Abstract: RFC8287 defines the extensions to MPLS LSP Ping and Traceroute for Segment Routing IGP-Prefix and IGP-Adjacency Segment Identifier (SIDs) with an MPLS data plane. RFC8287 proposes 3 Target FEC Stack Sub-TLVs. While the standard defines the format and procedure to handle those Sub-TLVs, it does not sufficiently clarify how the length of the Segment ID Sub-TLVs should be computed to include in the Length field of the Sub-TLVs which may result in interoperability issues.

- LOOPS (Localized Optimizations of Path Segments) Problem Statement and Opportunities (draft-li-tsvwg-loops-problem-opportunities)
By Li Yizhou, Xingwang Zhou, 2019-05-24 TXT HTML PDF
Abstract: In various network deployments, end to end paths are partitioned into multiple segments. In some cloud based WAN connections, multiple overlay tunnels in series are used to achieve better path selection and lower latency. In satellite communication, the end to end path is split into two terrestrial segments and a satellite segment. Packet losses can be caused both by random events or congestion in various deployments.
- Handling Large Certificates and Long Certificate Chains in TLS-based EAP Methods (draft-ms-emu-eaptlscert)
By Mohit Sethi, John Mattsson, Sean Turner, 2019-05-26 TXT HTML PDF
Abstract: EAP-TLS and other TLS-based EAP methods are widely deployed and used for network access authentication. Large certificates and long certificate chains combined with authenticators that drop an EAP session after only 40 - 50 round-trips is a major deployment problem. This memo looks at the this problem in detail and describes the potential solutions available.
- Name-Based Service Function Forwarder (nSFF) component within SFC framework (draft-trossen-sfc-name-based-sff)
By Dirk Trossen, Debashish Purkayastha, Akbar Rahman, 2019-05-26 TXT HTML PDF
Abstract: Adoption of cloud and fog technology allows operators to deploy a single "Service Function" to multiple "Execution locations". The decision to steer traffic to a specific location may change frequently based on load, proximity etc. Under the current SFC framework, steering traffic dynamically to the different execution end points require a specific 're-chaining', i.e., a change in the service function path reflecting the different IP endpoints to be used for the new execution points. This procedure may be complex and take time. In order to simplify re-chaining and reduce the time to complete the procedure, we discuss separating the logical Service Function Path from the specific execution end points. This can be done by identifying the Service Functions using a name rather than a routable IP endpoint (or Layer 2 address). This document describes the necessary extensions, additional functions and protocol details in SFF (Service Function Forwarder) to handle name based relationships.
- Realm Crossover for SASL via Diameter (draft-vanrein-diameter-sasl)
By Rick van Rein, 2019-05-25 TXT HTML PDF

- Using CLA-Specific Endpoint IDs to identify Channel Endpoint (draft-loiseau-dtn-cla-eid)
By Lucien Loiseau, 2018-11-20 TXT HTML PDF
Abstract: This document describes a specific EID scheme namely "cla" that meets the requirement for endpoint identification as defined in the Bundle Protocol and that also uniquely identifies a Convergence Layer Adapter "channel" and is, in essence, an interface identifier (IID). Such IID is comprised of two parts: a "cla-identifier" part that identifies a specific convergence layer adapter, and a "cla- parameters" part that is a cla-specific list of parameter describing a single channel managed by this convergence layer adapter.
- Synthetic IV (SIV) for non-AES ciphers and MACs (draft-madden-generalised-siv)
By Neil Madden, 2018-11-22 TXT HTML PDF
Abstract: This document specifies how the Synthetic Initialization Vector (SIV) block cipher mode of operation can be adapted to non-AES ciphers and message authentication codes (MACs), with block sizes and MAC tag sizes other than 128 bits. Concrete instantiations are defined using the XChaCha20 nonce-extended stream cipher combined with HMAC-SHA256.
- Multiple group membership (draft-park-mls-multiple-groups-requirement)
By Minho Park, 2018-11-20 TXT HTML PDF
Abstract: This document proposes a functional requirement of Message Level Security (MLS) which provide an efficient management for multiple groups. Although MLS defines an architecture and an abstract protocol for a secure group communication, it overlooks the need of multiple groups. This document describes a usecase of the multiple groups, and the need for an efficient multiple group membership management.
- PCEP extension to support reporting of dynamic tunnels (draft-paul-pce-dynamic-tunnel)
By Arijit Paul, 2018-11-20 TXT HTML PDF
Abstract: In a SDN environment, path computation element protocol(PCEP) (RFC 5440) is used between a controller and the network devices, using which controller can setup and tear down Resource ReserVation Protocol (RSVP) based label switched paths(LSPs) in the network having Path Computation Client (PCC) as Label Switched Router (LSR). In an environment where dynamic tunnels are used to provide MPLS based customer services instead of a Label Switched Path, the specifications lacks a method to report the Dynamic tunnels over PCEP session to PCE. This draft defines a method to advertise the dynamic tunnels via PCEP session to PCE.
