(10KB) This memo updates the IANA IPv4 and IPv6 Special-Purpose Address Registries to address issues raised by the definition of a \"global\" prefix. It also corrects several errors in registry entries to ensure the integrity of the IANA Special-Purpose Address Registries.
(39KB) In some scenarios, MPLS Transport Profile (MPLS-TP) pseudowires (PWs) (RFC 5921) may be statically configured when a dynamic control plane is not available. A fast protection mechanism for MPLS-TP PWs is needed to protect against the failure of an Attachment Circuit (AC), the failure of a Provider Edge (PE), or a failure in the Packet Switched Network (PSN). The framework and typical scenarios of dual- homing PW local protection are described in RFC 8184. This document proposes a dual-homing coordination mechanism for MPLS-TP PWs that is used for state exchange and switchover coordination between the dual- homing PEs for dual-homing PW local protection.
(24KB) This document describes a framework and several scenarios for a pseudowire (PW) dual-homing local protection mechanism that avoids unnecessary switchovers and does not depend on whether a control plane is used. A Dual-Node Interconnection (DNI) PW is used to carry traffic between the dual-homing Provider Edge (PE) nodes when a failure occurs in one of the Attachment Circuits (AC) or PWs. This PW dual-homing local protection mechanism is complementary to existing PW protection mechanisms.
(33KB) This memo introduces a content coding for HTTP that allows message payloads to be encrypted.
(116KB) This memo defines a portion of the Management Information Base (MIB) for use with network management protocols in internets based on TCP or IP. In particular, it defines objects for managing networks using the Precision Time Protocol (PTP), specified in IEEE Std. 1588-2008.
(107KB) Many protocols make use of points of extensibility that use constants to identify various protocol parameters. To ensure that the values in these fields do not have conflicting uses and to promote interoperability, their allocations are often coordinated by a central record keeper. For IETF protocols, that role is filled by the Internet Assigned Numbers Authority (IANA).
(174KB) When routing devices rely on modems to effect communications over wireless links, they need timely and accurate knowledge of the characteristics of the link (speed, state, etc.) in order to make routing decisions. In mobile or other environments where these characteristics change frequently, manual configurations or the inference of state through routing or transport protocols does not allow the router to make the best decisions. This document introduces a new protocol called the Dynamic Link Exchange Protocol (DLEP), which provides a bidirectional, event-driven communication channel between the router and the modem to facilitate communication of changing link characteristics.
(127KB) This document describes mechanisms for providing directory service to TRILL (Transparent Interconnection of Lots of Links) edge switches. The directory information provided can be used in reducing multi-destination traffic, particularly ARP / Neighbor Discovery (ND) and unknown unicast flooding. It can also be used to detect traffic with forged source addresses.
(30KB) The \"amr\" (Authentication Methods References) claim is defined and registered in the IANA \"JSON Web Token Claims\" registry, but no standard Authentication Method Reference values are currently defined. This specification establishes a registry for Authentication Method Reference values and defines an initial set of Authentication Method Reference values.
(34KB) This document describes a mechanism that allows a single router to share one or more circuits among multiple Intermediate System to Intermediate System (IS-IS) routing protocol instances.
(45KB) This document describes the key chain YANG data model. Key chains are commonly used for routing protocol authentication and other applications requiring symmetric keys. A key chain is a list containing one or more elements containing a Key ID, key string, send/accept lifetimes, and the associated authentication or encryption algorithm. By properly overlapping the send and accept lifetimes of multiple key chain elements, key strings and algorithms may be gracefully updated. By representing them in a YANG data model, key distribution can be automated.
(54KB) The IEC 61850 power utility automation family of standards describes methods using Ethernet and IP for distributing control and data frames within and between substations. The IEC 61850-90-5 and IEC 62351-9 standards specify the use of the Group Domain of Interpretation (GDOI) protocol (RFC 6407) to distribute security transforms for some IEC 61850 security protocols. This memo defines GDOI payloads to support those security protocols.
(93KB) TRILL (Transparent Interconnection of Lots of Links) supports multi-access LAN (Local Area Network) links where a single link can have multiple end stations and TRILL switches attached. Where multiple TRILL switches are attached to a link, native traffic to and from end stations on that link is handled by a subset of those TRILL switches called \"Appointed Forwarders\" as originally specified in RFC 6325, with the intent that native traffic in each VLAN be handled by at most one TRILL switch. This document clarifies and updates the Appointed Forwarder mechanism. It updates RFCs 6325 and 7177 and obsoletes RFC 6439.
(17KB) This document describes an OPTIONAL feature for active performance measurement protocols that allows use of the Precision Time Protocol timestamp format defined in IEEE 1588v2, as an alternative to the Network Time Protocol that is currently used.
(209KB) DHCPv6 as defined in \"Dynamic Host Configuration Protocol for IPv6 (DHCPv6)\" (RFC 3315) does not offer server redundancy. This document defines a protocol implementation to provide DHCPv6 failover, a mechanism for running two servers with the capability for either server to take over clients\' leases in case of server failure or network partition. It meets the requirements for DHCPv6 failover detailed in \"DHCPv6 Failover Requirements\" (RFC 7031).
(65KB) This document specifies a new Generic Associated Channel (G-ACh) for Residence Time Measurement (RTM) and describes how it can be used by time synchronization protocols within an MPLS domain.
(64KB) The IETF policies about Intellectual Property Rights (IPR), such as patent rights, relative to technologies developed in the IETF are designed to ensure that IETF working groups and participants have as much information as possible about any IPR constraints on a technical proposal as early as possible in the development process. The policies are intended to benefit the Internet community and the public at large, while respecting the legitimate rights of IPR holders. This document sets out the IETF policies concerning IPR related to technology worked on within the IETF. It also describes the objectives that the policies are designed to meet. This document updates RFC 2026 and, with RFC 5378, replaces Section 10 of RFC 2026. This document also obsoletes RFCs 3979 and 4879.
(59KB) This document describes a minimal mode of operation for an IPv6 over the TSCH mode of IEEE 802.15.4e (6TiSCH) network. This minimal mode of operation specifies the baseline set of protocols that need to be supported and the recommended configurations and modes of operation sufficient to enable a 6TiSCH functional network. 6TiSCH provides IPv6 connectivity over a Time-Slotted Channel Hopping (TSCH) mesh composed of IEEE Std 802.15.4 TSCH links. This minimal mode uses a collection of protocols with the respective configurations, including the IPv6 Low-Power Wireless Personal Area Network (6LoWPAN) framework, enabling interoperable IPv6 connectivity over IEEE Std 802.15.4 TSCH. This minimal configuration provides the necessary bandwidth for network and security bootstrapping and defines the proper link between the IETF protocols that interface to IEEE Std 802.15.4 TSCH. This minimal mode of operation should be implemented by all 6TiSCH-compliant devices.
(21KB) DHCPv6 Prefix Delegation allows a client to include a prefix-length hint value in the IA_PD option to indicate a preference for the size of the prefix to be delegated, but it is unclear about how the client and server should act in different situations involving the prefix-length hint. This document provides a summary of the existing problems with the prefix-length hint and guidance on what the client and server could do in different situations.
(26KB) This document describes how to use secure DNS to associate an S/MIME user\'s certificate with the intended domain name, similar to the way that DNS-Based Authentication of Named Entities (DANE), RFC 6698, does for TLS.
