"Network Computing Architecture" which became Network Computing System (NCS) and then a major part of DCE/RPC itself. The naming convention for transports that can be designed (as architectural plugins) and then made available to DCE/RPC echoes these origins, e.g. ncacn_np (SMB Named Pipes transport); ncacn_tcp (DCE/RPC over TCP/IP) and ncacn_http to name a small number. DCE/RPC's history is such that it's sometimes cited as an example of design by committee. It is also

DCE/RPC was originally commissioned by the Open Software Foundation, an industry consortium to set vendor- and technology-neutral open standards for computing infrastructure. None of the Unix vendors (now represented by the Open Group), wanted to use the complex DCE or such components as DCE/RPC at the time. Microsoft's Component Object Model is based heavily on MSRPC, adding

based systems. By integrating security, RPC and other distributed services on a single "official" distributed computing environment, OSF could offer a major advantage over SVR4, allowing any DCE-supporting system (namely OSF/1) to interoperate in a larger network. The DCE system was, to a large degree, based on independent developments made by each of the partners. DCE/RPC was derived from the "Network Computing System" (NCS) created at Apollo Computer. The naming service was derived from work done at Digital.

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. DCE/RPC was commissioned by the Open Software Foundation in a "Request for Technology" (1993 David Chappell). One of the key companies that contributed was Apollo Computer, who brought in NCA -

Microsoft RPC


Microsoft RPC (Microsoft Remote Procedure Call) is a modified version of DCE/RPC. Additions include partial support for UCS-2 (but not Unicode) strings, implicit handles, and complex calculations in the variable-length string and structure paradigms already present in DCE/RPC. The DCE 1.0 reference implementation only allows such constructs as "size_is(len)", or possibly "size_is(len-1)". MSRPC allows much more complex constructs such as "size_is(len / 2 - 1)" and even "length_is ((max & ~0x7)

DFS used DCE as the RPC, and DFS derived from the Andrew File System (AFS); DCE itself derived from a suite of technologies, including Apollo's NCS and Kerberos. Sun Microsystems and the Internet Society (ISOC) reached an agreement to cede "change control" of ONC RPC so that the ISOC's engineering-standards body, the Internet Engineering Task Force (IETF), could publish standards documents (RFCs)

The Open Group has stated it will work with the DCE community to make DCE available to the open source development community, as well as continuing to offer the source through The Open Group’s web site. DCE/RPC's reference implementation (version 1.1) was previously available under the BSD-compatible (Free Software) OSF/1.0 license, and is still available for at least Solaris,

DCE/RPC has strictly defined rules regarding marshalling and who is responsible for freeing memory. DCOM was a major competitor to CORBA. Proponents of both of these technologies saw them as one day becoming the model for code and service-reuse over the Internet. However, the difficulties involved in getting either of these technologies to work over Internet firewalls, and on unknown and

Later, the IETF chose to extend ONC RPC by adding a new authentication flavor based on Generic Security Services Application Program Interface (GSSAPI), RPCSEC GSS, to meet IETF requirements that protocol standards have adequate security. Later, Sun and ISOC reached a similar agreement to give ISOC change control over NFS, although writing the contract carefully to exclude NFS version 2 and

ESIOPs can also be used to layer CORBA on top of some non-CORBA technology stack, such as Distributed Computing Environment (DCE). DCE Common Inter-ORB Protocol (DCE-CIOP) is an ESIOP for use in DCE. It maps CORBA to DCE RPC and CDR (Command Data Representation). DCE-CIOP is defined in chapter 16 of

Badlock () is a security bug disclosed on April 12, 2016 affecting the Security Account Manager (SAM) and Local Security Authority (Domain Policy) (LSAD) remote protocols supported by Windows and Samba servers. Both SAM and LSAD are layered onto the DCE 1.1 Remote Procedure Call (DCE/RPC) protocol. As implemented in Samba and Windows, the RPC services allowed an attacker to become man in the middle. Although the vulnerability was discovered during the development of Samba, the namegiving SMB protocol itself is not affected

DCEThreads


DCEThreads is an implementation of POSIX Draft 4 threads. DCE/RPC was under development, but the POSIX committee had not finalised POSIX threads at the time. The Open Group had to make a decision about what to stick with, and unfortunately the final POSIX threads were different from their selection. POSIX Draft 4 threads were limited to begin with (the final standard fixed these). Microsoft adopted DCE/RPC wholesale in Windows NT as MSRPC and also in DCOM. Most of the stability and reliability problems that programmers associate with

DCEThreads


DCOM services - especially memory leaks, exception handling problems and thread cancellation stability issues - can be traced back to the use of POSIX Draft 4 threads. DCE/RPC is sufficiently complex that the issue of updating it to solve and modernise the POSIX Draft 4 threading problem requires highly skilled and highly specific programming knowledge. Consequently, for all that it can accomplish, the reference implementation of DCE/RPC languishes due to a lack of information and resources. The key difference between POSIX Draft 4 threads and the final POSIX threads specification

One of the major uses of DCE today is Microsoft's DCOM and ODBC systems, which use DCE/RPC (in MSRPC) as their network transport layer. OSF and its projects eventually became part of The Open Group, which released DCE 1.2.2 under a free software license (the LGPL) on 12 January 2005. DCE 1.1 was available much earlier under the OSF BSD license, and resulted in FreeDCE being

DCE/RPC utilises thread cancellation to propagate signals across the "Remote" of RPC, such that for example a client application terminating a thread results in its corresponding thread on the server also being terminated in the same way. Unfortunately, the final POSIX specification does not include such sophisticated cancellation methodology, and, given the difficulties that the Unix vendors had in correctly implementing the POSIX threads specification, it is not surprising that it was

COM was the major software development platform for Windows and, as such, influenced development of a number of supporting technologies. It was likewise heavily influenced by earlier technologies. As a cross-language component model, COM relies on an interface definition language, or IDL, to describe the objects and associated functions. The COM IDL is based heavily on the feature-rich DCE/RPC IDL, with object-oriented

While OLE 1 was focused on compound documents, COM and OLE 2 were designed to address software components in general. Text conversations and Windows messages had proved not to be flexible enough to allow sharing application features in a robust and extensible way, so COM was created as a new foundation, and OLE changed to OLE2.

It allows for multiplexing of the handlers as the kernel take care of initiating extra worker threads if the load is increased and vice versa, if the load is decreased it destroys the extra worker threads.

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. The addition of the "D" to COM was due to extensive use of DCE/RPC (Distributed Computing Environment/Remote Procedure Calls) – more specifically Microsoft's enhanced version, known as MSRPC.

In 2015, the DCE/SP was responsible for the eradication of 3,932,201 cultivated outdoor cannabis plants and 325,019 indoor plants for a total of 4,257,220 marijuana plants. In addition, the DCE/SP accounted for 6,278 arrests and the seizure in excess of $29.7 million of cultivator assets.

There is no corresponding signal that the DTE could use to temporarily halt incoming data from the DCE. Thus RS-232's use of the RTS and CTS signals, per the older versions of the standard, is asymmetric. This scheme is also employed in present-day RS-232 to RS-485 converters.

The practical difference is just that XML-RPC is much more structured, which means common library code can be used to implement clients and servers and there is less design and documentation work for a specific application protocol. One salient technical difference between typical RESTful protocols and XML-RPC is that the RESTful protocol uses the HTTP URI for parameter information whereas with XML-RPC, the URI just identifies the server.

A Signal Transfer Point (STP) is a router that relays SS7 messages between "signaling end-points" (SEPs) and other signaling transfer points (STPs). Typical SEPs include "service switching points" (SSPs) and "service control points" (SCPs). The STP is connected to adjacent SEPs and STPs via signaling links. Based on the address fields of the SS7 messages, the STP routes the messages to the appropriate outgoing signaling link. Edge STPs can also route based upon message body content using

JSON-RPC


JSON-RPC is a remote procedure call protocol encoded in JSON. It is a very simple protocol (and very similar to XML-RPC), defining only a few data types and commands. JSON-RPC allows for notifications (data sent to the server that does not require a response) and for multiple calls to be sent to the server which may be answered out of order. JSON-RPC works by sending a request to a server implementing this protocol. The client in that case is typically software intending to

Two types of RPC are implemented on DART: traditional RPC, and ONC RPC. Due to DART’s multi-threaded architecture, traditional RPC has been implemented on DART with several modifications. For example, on a SUN OS, the RPC code generator, RPCGEN, assumes a single-threaded UNIX process that calls into the library directly.

XML-RPC


XML-RPC is a remote procedure call (RPC) protocol which uses XML to encode its calls and HTTP as a transport mechanism. The XML-RPC protocol was created in 1998 by Dave Winer of UserLand Software and Microsoft, with Microsoft seeing the protocol as an essential part of scaling up its efforts in business-to-business e-commerce. As new functionality was introduced, the standard evolved into what is now SOAP. UserLand supported XML-RPC from version 5.1 of its Frontier web content management system, released

Data circuit-terminating equipment


A data circuit-terminating equipment (DCE) is a device that sits between the data terminal equipment (DTE) and a data transmission circuit. It is also called data communication(s) equipment and data carrier equipment. Usually, the DTE device is the terminal (or computer), and the DCE is a modem. In a data station, the DCE performs functions such as signal conversion, coding, and line clocking and may be a part of the DTE or intermediate equipment. Interfacing equipment may be required to couple the

Omitting key attributes typically causes respondents to make inferences (guesses) about those missing from the DCE, leading to omitted variable problems. The levels must typically include all those currently available, and often are expanded to include those that are possible in future – this is particularly useful in guiding product development.

In computing, the Distributed Computing Environment (DCE) software system was developed in the early 1990s from the work of the Open Software Foundation (OSF), a consortium (founded in 1988) that included Apollo Computer (part of Hewlett-Packard from 1989), IBM, Digital Equipment Corporation, and others. The DCE supplies a framework and a toolkit for developing client/server applications. The framework includes: DCE represented a big step in the direction of standardization of architectures, which had previously been manufacturer-dependent.
