Link-Layer Address Assignment Mechanism for DHCPv6
In certain environments, e.g., large-scale virtualization deployments, new devices are created in an automated manner. Such devices may have their link-layer addresses assigned in an automated fashion. With sufficient scale, the likelihood of a collision using random assignment without duplication detection is not acceptable. Therefore, an allocation mechanism is required. This document proposes a…
Personal Assertion Token (PASSporT) Extension for Diverted Calls
The Personal Assertion Token (PASSporT) is specified in RFC 8225 to convey cryptographically signed information about the people involved in personal communications. This document extends PASSporT to include an indication that a call has been diverted from its original destination to a new one. This information can greatly improve the decisions made by verification services in call forwarding scen…
Secret Key Transaction Authentication for DNS (TSIG)
This document describes a protocol for transaction-level authentication using shared secrets and one-way hashing. It can be used to authenticate dynamic updates to a DNS zone as coming from an approved client or to authenticate responses as coming from an approved name server. No recommendation is made here for distributing the shared secrets; it is expected that a network administrator will stati…
This document defines a YANG data model for Layer 2 network topologies. In particular, this data model augments the generic network and network topology data models with topology attributes that are specific to Layer 2.
Concise Binary Object Representation (CBOR) Tags for Date
The Concise Binary Object Representation (CBOR), as specified in RFC 7049, is a data format whose design goals include the possibility of extremely small code size, fairly small message size, and extensibility without the need for version negotiation. In CBOR, one point of extensibility is the definition of CBOR tags. RFC 7049 defines two tags for time: CBOR tag 0 (date/time string as per RFC 3339…
HTTP defines proactive content negotiation to allow servers to select the appropriate response for a given request, based upon the user agent's characteristics, as expressed in request headers. In practice, user agents are often unwilling to send those request headers, because it is not clear whether they will be used, and sending them impacts both performance and privacy. This document defines an…
This document describes a set of data types and associated algorithms that are intended to make it easier and safer to define and handle HTTP header and trailer fields, known as "Structured Fields", "Structured Headers", or "Structured Trailers". It is intended for use by specifications of new HTTP fields that wish to use a common syntax that is more restrictive than traditional HTTP field values.
Extensible Authentication Protocol (EAP) Session-Id Derivation for EAP Subscriber Identity Module (EAP-SIM), EAP Authentication and Key Agreement (EAP-AKA), and Protected EAP (PEAP)
RFC 5247 is updated to define and clarify EAP Session-Id derivation for multiple Extensible Authentication Protocol (EAP) methods. The derivation of Session-Id was not given for EAP Subscriber Identity Module (EAP-SIM) or EAP Authentication and Key Agreement (EAP-AKA) when using the fast reconnect exchange instead of full authentication. The derivation of Session-Id for full authentication is clar…
This document specifies the Deterministic Networking (DetNet) data plane operation for IP hosts and routers that provide DetNet service to IP-encapsulated data. No DetNet-specific encapsulation is defined to support IP flows; instead, the existing IP-layer and higher-layer protocol header information is used to support flow identification and DetNet service delivery. This document builds on the De…

This document provides an overall framework for the Deterministic Networking (DetNet) data plane. It covers concepts and considerations that are generally common to any DetNet data plane specification. It describes related Controller Plane considerations as well.
Randomness is a crucial ingredient for Transport Layer Security (TLS) and related security protocols. Weak or predictable "cryptographically secure" pseudorandom number generators (CSPRNGs) can be abused or exploited for malicious purposes. An initial entropy source that seeds a CSPRNG might be weak or broken as well, which can also lead to critical and systemic security problems. This document de…
Poll-Based Security Event Token (SET) Delivery Using HTTP
This specification defines how a series of Security Event Tokens (SETs) can be delivered to an intended recipient using HTTP POST over TLS initiated as a poll by the recipient. The specification also defines how delivery can be assured, subject to the SET Recipient's need for assurance.
Push-Based Security Event Token (SET) Delivery Using HTTP
This specification defines how a Security Event Token (SET) can be delivered to an intended recipient using HTTP POST over TLS. The SET is transmitted in the body of an HTTP POST request to an endpoint operated by the recipient, and the recipient indicates successful or failed transmission via the HTTP response.
PCE Communication Protocol (PCEP) Extensions for Label Switched Path (LSP) Scheduling with Stateful PCE
This document defines a set of extensions to the stateful PCE Communication Protocol (PCEP) to enable Label Switched Path (LSP) path computation, activation, setup, and deletion based on scheduled time intervals for the LSP and the actual network resource usage in a centralized network environment, as stated in RFC 8413.
Update to the Cryptographic Message Syntax (CMS) for Algorithm Identifier Protection
This document updates the Cryptographic Message Syntax (CMS) specified in RFC 5652 to ensure that algorithm identifiers in signed-data and authenticated-data content types are adequately protected.
This document presents operational, policy, and security considerations for DNS recursive resolver operators who choose to offer DNS privacy services. With these recommendations, the operator can make deliberate decisions regarding which services to provide, as well as understanding how those decisions and the alternatives impact the privacy of users. This document also presents a non-normative fr…
IPv6 over Low-Power Wireless Personal Area Network (6LoWPAN) Selective Fragment Recovery
This document updates RFC 4944 with a protocol that forwards individual fragments across a route-over mesh and recovers them end to end, with congestion control capabilities to protect the network.
On Forwarding 6LoWPAN Fragments over a Multi-Hop IPv6 Network
This document provides generic rules to enable the forwarding of an IPv6 over Low-Power Wireless Personal Area Network (6LoWPAN) fragment over a route-over network. Forwarding fragments can improve both end-to-end latency and reliability as well as reduce the buffer requirements in intermediate nodes; it may be implemented using RFC 4944 and Virtual Reassembly Buffers (VRBs).
This document updates RFCs 6775 and 8505 in order to enable proxy services for IPv6 Neighbor Discovery by Routing Registrars called "Backbone Routers". Backbone Routers are placed along the wireless edge of a backbone and federate multiple wireless links to form a single Multi-Link Subnet (MLSN).
Address-Protected Neighbor Discovery for Low-Power and Lossy Networks
This document updates the IPv6 over Low-Power Wireless Personal Area Network (6LoWPAN) Neighbor Discovery (ND) protocol defined in RFCs 6775 and 8505. The new extension is called Address-Protected Neighbor Discovery (AP-ND), and it protects the owner of an address against address theft and impersonation attacks in a Low-Power and Lossy Network (LLN). Nodes supporting this extension compute a crypt…
This document proposes a format, called JSON Type Definition (JTD), for describing the shape of JavaScript Object Notation (JSON) messages. Its main goals are to enable code generation from schemas as well as portable validation with standardized error indicators. To this end, JTD is intentionally limited to be no more expressive than the type systems of mainstream programming languages. This inte…
Network virtualization involves the cooperation of devices with a wide variety of capabilities such as software and hardware tunnel endpoints, transit fabrics, and centralized control clusters. As a result of their role in tying together different elements of the system, the requirements on tunnels are influenced by all of these components. Therefore, flexibility is the most important aspect of a …
This document specifies a DHCPv4 option to indicate that a host supports an IPv6-only mode and is willing to forgo obtaining an IPv4 address if the network provides IPv6 connectivity. It also updates RFC 2563 to specify DHCPv4 server behavior when the server receives a DHCPDISCOVER not containing the Auto-Configure option but containing the new option defined in this document.
