Happy Eyeballs Version 2: Better Connectivity Using Concurrency
Many communication protocols operating over the modern Internet use hostnames. These often resolve to multiple IP addresses, each of which may have different performance and connectivity characteristics. Since specific addresses or address families (IPv4 or IPv6) may be blocked, broken, or sub-optimal on a network, clients that attempt multiple connections in parallel have a chance of establishing…

This memo introduces an informational HTTP status code that can be used to convey hints that help a client make preparations for processing the final response.
Encapsulation for Bit Index Explicit Replication (BIER) in MPLS and Non-MPLS Networks
Bit Index Explicit Replication (BIER) is an architecture that provides optimal multicast forwarding through a "multicast domain", without requiring intermediate routers to maintain any per-flow state or to engage in an explicit tree-building protocol. When a multicast data packet enters the domain, the ingress router determines the set of egress routers to which the packet needs to be sent. The in…
EST (Enrollment over Secure Transport) Extensions
The EST (Enrollment over Secure Transport) protocol defines the Well-Known URI (Uniform Resource Identifier) -- /.well-known/est -- along with a number of other path components that clients use for PKI (Public Key Infrastructure) services, namely certificate enrollment (e.g., /simpleenroll). This document defines a number of other PKI services as additional path components -- specifically, firmwar…
Common YANG Data Types for the Routing Area
This document defines a collection of common data types using the YANG data modeling language. These derived common types are designed to be imported by other modules defined in the routing area.
A Framework for Multicast in Network Virtualization over Layer 3
This document provides a framework for supporting multicast traffic in a network that uses Network Virtualization over Layer 3 (NVO3). Both infrastructure multicast and application-specific multicast are discussed. It describes the various mechanisms that can be used for delivering such traffic as well as the data plane and control plane considerations for each of the mechanisms.
Voluntary Application Server Identification (VAPID) for Web Push
An application server can use the Voluntary Application Server Identification (VAPID) method described in this document to voluntarily identify itself to a push service. The "vapid" authentication scheme allows a client to include its identity in a signed token with requests that it makes. The signature can be used by the push service to attribute requests that are made by the same application ser…
Message Encryption for Web Push
This document describes a message encryption scheme for the Web Push protocol. This scheme provides confidentiality and integrity for messages sent from an application server to a user agent.
The Flow Queue CoDel Packet Scheduler and Active Queue Management Algorithm
This memo presents the FQ-CoDel hybrid packet scheduler and Active Queue Management (AQM) algorithm, a powerful tool for fighting bufferbloat and reducing latency. FQ-CoDel mixes packets from multiple flows and reduces the impact of head-of-line blocking from bursty traffic. It provides isolation for low-rate traffic such as DNS, web, and videoconferencing traffic. It improves utilisation across t…
Controlled Delay Active Queue Management
This document describes CoDel (Controlled Delay) -- a general framework that controls bufferbloat-generated excess delay in modern networking environments. CoDel consists of an estimator, a setpoint, and a control loop. It requires no configuration in normal Internet deployments.
Web Linking
This specification defines a model for the relationships between resources on the Web ("links") and the type of those relationships ("link relation types"). It also defines the serialisation of such links in HTTP headers with the Link header field.
Label Switched Path (LSP) Ping/Traceroute for Segment Routing (SR) IGP-Prefix and IGP-Adjacency Segment Identifiers (SIDs) with MPLS Data Planes
A Segment Routing (SR) architecture leverages source routing and tunneling paradigms and can be directly applied to the use of a Multiprotocol Label Switching (MPLS) data plane. A node steers a packet through a controlled set of instructions called "segments" by prepending the packet with an SR header. The segment assignment and forwarding semantic nature of SR raises additional considerations for…
RTP/RTCP Extension for RTP Splicing Notification
Content splicing is a process that replaces the content of a main multimedia stream with other multimedia content and that delivers the substitutive multimedia content to the receivers for a period of time. The splicer is designed to handle RTP splicing and needs to know when to start and end the splicing. This memo defines two RTP/RTCP extensions to indicate the splicing-related information to th…
A General Mechanism for RTP Header Extensions
This document provides a general mechanism to use the header extension feature of RTP (the Real-time Transport Protocol). It provides the option to use a small number of small extensions in each RTP packet, where the universe of possible extensions is large and registration is decentralized. The actual extensions in use in a session are signaled in the setup information for that session. This docu…
