In distributed computing, a remote procedure call (RPC) is when a computer program causes a procedure (subroutine) to execute in a different address space, which is written as if it were a normal (local) procedure call, without the programmer explicitly writing the details for the remote interaction. That is, the programmer writes essentially the same code whether the subroutine is local to the executing program, or remote. This is a form of client–server interaction, typically implemented via a request–response message passing system. In the object-oriented programming paradigm, RPCs are represented by remote method invocation (RMI). The RPC model implies a level of location transparency, namely that calling procedures are largely the same whether they are local or remote, but usually, they are not identical, so local calls can be distinguished from remote calls. Remote calls are usually orders of magnitude slower and less reliable than local calls, so distinguishing them is important.
Samba is a free software re-implementation of the SMB networking protocol, and was originally developed by Andrew Tridgell. Samba provides file and print services for various Microsoft Windows clients and can integrate with a Microsoft Windows Server domain, either as a Domain Controller (DC) or as a domain member. As of version 4, it supports Active Directory and Microsoft Windows NT domains.
Network File System (NFS) is a distributed file system protocol originally developed by Sun Microsystems (Sun) in 1984, allowing a user on a client computer to access files over a computer network much like local storage is accessed. NFS, like many other protocols, builds on the Open Network Computing Remote Procedure Call system. NFS is an open IETF standard defined in a Request for Comments (RFC), allowing anyone to implement the protocol.
Distributed Component Object Model (DCOM) is a proprietary Microsoft technology for communication between software components on networked computers. DCOM, which originally was called "Network OLE", extends Microsoft's COM, and provides the communication substrate under Microsoft's COM+ application server infrastructure.
In computer science, inter-process communication (IPC), also spelled interprocess communication, are the mechanisms provided by an operating system for processes to manage shared data. Typically, applications can use IPC, categorized as clients and servers, where the client requests data and the server responds to client requests. Many applications are both clients and servers, as commonly seen in distributed computing.
An interface description language or interface definition language (IDL) is a generic term for a language that lets a program or object written in one language communicate with another program written in an unknown language. IDLs are usually used to describe data types and interfaces in a language-independent way, for example, between those written in C++ and those written in Java.
A Universally Unique Identifier (UUID) is a 128-bit label used for information in computer systems. The term Globally Unique Identifier (GUID) is also used, mostly in Microsoft systems.
In distributed computing, General Inter-ORB Protocol (GIOP) is the message protocol by which object request brokers (ORBs) communicate in CORBA. Standards associated with the protocol are maintained by the Object Management Group (OMG). The current version of GIOP is 2.0.2. The GIOP architecture provides several concrete protocols, including:
In computing, a named pipe is an extension to the traditional pipe concept on Unix and Unix-like systems, and is one of the methods of inter-process communication (IPC). The concept is also found in OS/2 and Microsoft Windows, although the semantics differ substantially. A traditional pipe is "unnamed" and lasts only as long as the process. A named pipe, however, can last as long as the system is up, beyond the life of the process. It can be deleted if no longer used. Usually a named pipe appears as a file, and generally processes attach to it for IPC.
The Distributed Computing Environment (DCE) is a software system developed in the early 1990s from the work of the Open Software Foundation (OSF), a consortium founded in 1988 that included Apollo Computer, IBM, Digital Equipment Corporation, and others. The DCE supplies a framework and a toolkit for developing client/server applications. The framework includes:
Cairo was the codename for a project at Microsoft from 1991 to 1996. Its charter was to build technologies for a next-generation operating system that would fulfill Bill Gates's vision of "information at your fingertips." Cairo never shipped, although portions of its technologies have since appeared in other products.
Open Network Computing (ONC) Remote Procedure Call (RPC), commonly known as Sun RPC is a remote procedure call system. ONC was originally developed by Sun Microsystems in the 1980s as part of their Network File System project.
Distributed File System (DFS) is a set of client and server services that allow an organization using Microsoft Windows servers to organize many distributed SMB file shares into a distributed file system. DFS has two components to its service: Location transparency and Redundancy. Together, these components enable data availability in the case of failure or heavy load by allowing shares in multiple different locations to be logically grouped under one folder, the "DFS root".
Microsoft RPC is a modified version of DCE/RPC. Additions include partial support for UCS-2 strings, implicit handles, and complex calculations in the variable-length string and structure paradigms already present in DCE/RPC.
DCE/RPC, short for "Distributed Computing Environment / Remote Procedure Calls", is the remote procedure call system developed for the Distributed Computing Environment (DCE). This system allows programmers to write distributed software as if it were all working on the same computer, without having to worry about the underlying network code.
DCEThreads is an implementation of POSIX Draft 4 threads. DCE Stands for "Distributed Computing Environment" DCEThreads allowed users to create multiple avenues of execution in a single process. It is based on pthreads interface.
The DCE Distributed File System (DCE/DFS) is the remote file access protocol used with the Distributed Computing Environment. It was a variant of Andrew File System (AFS), based on the AFS Version 3.0 protocol that was developed commercially by Transarc Corporation. AFS Version 3.0 was in turn based on the AFS Version 2.0 protocol originally developed at Carnegie Mellon University.
Microsoft Interface Definition Language (MIDL) is a text-based interface description language from Microsoft, based on the DCE/RPC IDL which it extends for use with the Microsoft Component Object Model. Its compiler is also called MIDL.
The Network Computing System (NCS) was an implementation of the Network Computing Architecture (NCA). It was created at Apollo Computer in the 1980s. It comprised a set of tools for implementing distributed software applications, or distributed computing. The three principal components of NCS were a runtime environment for remote procedure calls, a network interface definition language (NIDL) compiler, and a location broker service. The location broker differentiated NCS from similar offerings, such as the rival Open Network Computing technology from Sun Microsystems, by permitting services to be distributed in a dynamic fashion and offering the possibility of "location independence".
Badlock is a security bug disclosed on April 12, 2016 affecting the Security Account Manager (SAM) and Local Security Authority (LSAD) remote protocols supported by Windows and Samba servers.
