directory services

In many Internet of Things (IoT) applications, direct discovery of resources is not practical due to sleeping nodes or networks where multicast traffic is inefficient. These problems can be solved by employing an entity called a Resource Directory (RD), which contains information about resources held on other servers, allowing lookups to be performed for those resources. The input to an RD is composed of links, and the output is composed of links constructed from the information stored in the RD. This document specifies the web interfaces that an RD supports for web servers to discover the RD and to register, maintain, look up, and remove information on resources. Furthermore, new target attributes useful in conjunction with an RD are defined.

This document specifies the procedures for interoperation between Multicast Virtual Private Network (MVPN) Source-Active (SA) routes and customer Multicast Source Discovery Protocol (MSDP) SA 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 Provider Edge (PE) routers that are customer MSDP peers. This document updates RFC 6514.

This document describes how data center networks can benefit from non-RBridge nodes performing TRILL (Transparent Interconnection of Lots of Links) encapsulation with assistance from a directory service.

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.

Edge TRILL (Transparent Interconnection of Lots of Links) switches currently learn the mapping between MAC (Media Access Control) addresses and their egress TRILL switch by observing the data packets they ingress or egress or by the TRILL ESADI (End-Station Address Distribution Information) protocol. When an ingress TRILL switch receives a data frame for a destination address (MAC&Label) that the switch does not know, the data frame is flooded within the frame's Data Label across the TRILL campus.

This document describes the framework for using directory services to assist edge TRILL switches in reducing multi-destination frames, particularly unknown unicast frames flooding, and ARP/ND (Address Resolution Protocol / Neighbor Discovery), thus improving TRILL network scalability and security.

Voice messaging is traditionally addressed using telephone number addressing. This document describes two techniques for routing voice messages based on a telephone number. The complete service uses the Voice Profile for Internet Mail (VPIM) Directory service to lookup a VPIM email address with a telephone number and confirm that the address is both valid and associated with the intended recipient. However, this service will take time to become widely deployed in the near term. This document also describes a basic send-and-pray service that routes and delivers messages using only the ENUM telephone number resolution service and the existing DNS mail routing facilities.

This document provides details of the Voice Profile for Internet Mail (VPIM) directory service. The service provides the email address of the recipient that is given a telephone number. It optionally provides the spoken name of the recipient and the media capabilities of the recipient.

The VPIM directory Schema provides essential additional attributes to recreate the voice mail user experience using standardized directories. This user experience provides, at the time of addressing, basic assurances that the message will be delivered as intended. This document combines two earlier documents, one from Anne Brown and one from Greg Vaudreuil, that define a voice messaging schema into a single working group submission. [STANDARDS-TRACK]

This document is one of a set of documents that together describe all aspects of the Internet Printing Protocol (IPP). IPP is an application-level protocol that can be used for distributed printing on the Internet. There are multiple parts to IPP, but the primary architectural components are the Model, the Protocol, and an interface to Directory Services. This document provides a statement of the requirements for notifications as an optional part of an IPP Service. This memo provides information for the Internet community.

This document describes the Mesh-enhanced Service Location Protocol (mSLP). mSLP enhances the Service Location Protocol (SLP) with a scope-based fully-meshed peering Directory Agent (DA) architecture. Peer DAs exchange new service registrations in shared scopes via anti- entropy and direct forwarding. mSLP improves the reliability and consistency of SLP DA services, and simplifies Service Agent (SA) registrations in systems with multiple DAs. mSLP is backward compatible with SLPv2 and can be deployed incrementally. This memo defines an Experimental Protocol for the Internet community.

The overarching goal of this project is to develop the necessary technical infrastructure to provide a single-access-point service for searching for whitepages information on Swedish Internet users. This memo provides information for the Internet community.

This document defines the basic principle for establishing a mesh, that interoperating services should exchange index objects, according to the architecture of the mesh (e.g., hierarchical, or graph-like, preferably without loops!). The Common Indexing Protocol (CIP) is designed to facilitate the creation not only of query referral indexes, but also of meshes of (loosely) affiliated referral indexes. The purpose of such a mesh of servers is to implement some kind of distributed sharing of indexing and/or searching tasks across different servers. So far, the TISDAG (Technical Infrastructure for Swedish Directory Access Gateways) project has focused on creating a single referral index; the obvious next step is to integrate that into a larger set of interoperating services. This memo provides information for the Internet community.

This document catalogues some of the experiences gained in developing the necessary infrastructure for a national (i.e., multi-organizational) directory service and pilot deployment of the service in an environment with off-the-shelf directory service products. This memo provides information for the Internet community.

Drawing from experiences with the TISDAG (Technical Infrastructure for Swedish Directory Access Gateways) project, this document outlines an approach to providing the necessary infrastructure for integrating such widely-scattered servers into a single service, rather than attempting to mandate a single protocol and schema set for all participating servers to use. This memo provides information for the Internet community.

This memo defines a portion of the Management Information Base (MIB) for use with network management protocols in the Internet community. [STANDARDS-TRACK]

This report describes the results of a meeting held at the November IETF (Internet Engineering Task Force) in Houston, TX, on November 2, 1993, to discuss the future of and approaches to a white pages directory services for the Internet. This memo provides information for the Internet community. This memo does not specify an Internet standard of any kind.

This document defines a mechanism by which a user-interface may access a textual DAP-like interface over a TCP/IP connection. This is a local mechanism. This memo provides information for the Internet community. It does not specify any standard.

This memo proposes a program to develop a directory service for the Internet. It reports the results of a meeting held in February 1989, which was convened to review requirements and options for such a service. This proposal is offered for comment, and does not represent a committed research activity of the Internet community.
