TLDR
As networks and internetworks of computers expand in size and scope, discovery and location of resources becomes a primary function of the networked computing environment and dynamic directory services provide more timely and accurate information about network resources than static tables.Abstract:
As networks and internetworks of computers expand in size and scope, discovery and location of resources becomes a primary function of the networked computing environment. Static tables describing network resources have been replaced by dynamic directory services, such as X.500 and the Internet Domain Name System. These dynamic directory services provide more timely and accurate information about network resources than static tables.A wide variety of services address various components of the resource discovery and location problem. These services can be loosely classified as either low-level protocols or high-level services. Low-level protocols, such as RARP and ICMP, are simple delivery protocols and provide limited information; high-level services, such as the Internet Domain Name System and X.500, use complex delivery protocols to answer complex queries. Neither class of directory service is appropriate in all situations. Low-level services are too restrictive in the type of queries and information they support, while high-level services may be too expensive for some low-function networks.read more

Method of accessing a target entity over a communications network
TL;DR: In this article, a method of accessing a target entity over a communication network employs a distributed database system similar top the DNS of the Internet; indeed the DNS may be used as the required distributed database.
Patent
Telecommunications system and method providing generic network access service
Jean-René Bouvier,John O'connell +1 more
TL;DR: In this article, a generic access service is provided in a telephone system to enable users to get dialup access to different network access services, and user profile data showing which access services a user subscribes to is held on a database accessible to the service control subsystem of the telephone system.
Patent
Universal storage management system
TL;DR: In this article, a universal storage management system which facilitates storage of data from a client computer and computer network is described, which facilitates reading and writing of data by handling I/O operations.
Patent
Method and system for incorporating filtered roles in a directory system
TL;DR: In this article, the difference between role types relates to their capabilities, which in turn derive from how they are implemented, and several types of roles are disclosed, including filtered roles, which use an LDAP filter to search a designated portion of the directory system.
Patent
Method of providing telecommunication services
TL;DR: In this article, the authors present a system where the service logic and data placed on a server (51) are accessible over the Internet (50), allowing anyone to access useful telephone data such as time-of-day routing or diversion number information of a user.

User Datagram Protocol
TL;DR: UDP does not guarantee reliability or ordering in the way that TCP does, but its stateless nature is also useful for servers that answer small queries from huge numbers of clients.
Internet Protocol
TL;DR: Along with TCP, IP represents the heart of the Internet protocols and has two primary responsibilities: providing connectionless, best-effort delivery of datagrams through an internetwork; and providing fragmentation and reassembly of data links to support data links with different maximum transmission unit (MTU) sizes.
Domain names - implementation and specification
TL;DR: This RFC is the revised specification of the protocol and format used in the implementation of the Domain Name System and it obsoletes RFC-883.
Domain names - concepts and facilities
TL;DR: This memo describes the domain style names and their used for host address look up and electronic mail forwarding and discusses the clients and servers in the domain name system and the protocol used between them.
