Apr 27, 2018 · Named pipes have features not unlike TCP connections, but there are important differences. Because a fifo has a persistent filesystem name you can write to it even when there is no reader, admittedly the writes will block (without async or non-blocking I/O), though you won't loose data if the receiver isn't started (or is being restarted).
TCP/IP Transfer time: 2.5 Seconds Named Pipes Transfer time: 3.1 Seconds. Now, if you go outside the machine and connect to a remote computer on your network the performance for named pipes is much worse: TCP/IP Transfer time: 12 Seconds Named Pipes Transfer time: 2.5 Minutes (Yes Minutes!)
Sep 21, 2015 · For forcing TCP/IP connections instead of Named Pipes connections is to use an IP address (instead of a host-name) as the data source within your connection strings, which forces the use of TCP/IP connectivity or pre-pend "tcp:" to the front of your host names in the data source section of your connection string.
Lasso provides objects for TCP, TCP/SSL and UDP networking. It also provides objects for local communications over named pipes. These networking objects are designed to fit tightly into the language runtime's threading model. Each method call that might block accepts a timeout parameter.
This article tackles the Options section within the TCP Header. Sections covered include: Maximum Segment Size, Improving performance with Window Scaling, Selective Acknowledgements, Timestamps, Nop and much more. All topics include detailed diagrams and examples.

TCP Server: Deselect the Connect to Existing Pipe/Socket check box and specify the port number in the Path/Address field. This is typically 23 or 2023. This is typically 23 or 2023. Note that on UNIX-like systems you will have to use a port a number greater than 1024 for regular users. Anonymous pipe: A unidirectional data channel using standard input and output. Data written to the write-end of the pipe is buffered by the operating system until it is read from the read-end of the pipe. Two-way communication between processes can be achieved by using two pipes in opposite "directions". All POSIX systems, Windows Named pipe

Oct 08, 2002 · SMB, which stands for Server Message Block, is a protocol for sharing files, printers, serial ports, and communications abstractions such as named pipes and mail slots between computers. The earliest document I have on the SMB protocol is an IBM document from 1985. It is a copy of an IBM Personal Computer Seminar Proceedings from May 1985.

IPC binding: The NetNamedPipeBinding class, this uses named pipes as a transport for same-machine communication. It is the most secure binding since it cannot accept calls from outside the machine and it supports a variety of features similar to the TCP binding. It can be used efficiently for cross product communication.

Speed of named pipe vs tcp/ip vs shared memory; Named Pipe communication between two terminals; Named Pipes Client in MQL4 and Server in C++; 40886.
Not regarding this situation specifically but TCP/IP sockets is a less "chatty" protocol than Named Pipes, there's less comunication between cient and server. It has to be said that this is generally not noticeable on a 100MB LAN, it can become apparent on a WAN. Have a look at "Named Pipes vs. TCP/IP Sockets" in BOL HTH Jasper Smith
When Named Pipes was disabled? I had an issue in my production. The following information is from SQL Server logs: 2005-03-20 14:32:22.37 serverSQL server listening on TCP, Shared Memory, Named Pipes. 2005-03-20 15:02:36.32 serverSQL server listening on TCP, Shared Memory, Named Pipes.

The Windows Server 2012 / 2012 R2 Member Server Security Technical Implementation Guide (STIG) is published as a tool to improve the security of Department of Defense (DoD) information systems.
Named Pipes provides easy access to Remote Procedure Calls (RPC) within a single security domain and thus is advantageous to these applications. Usually TCP Protocol is good in practice because you don't have to care about all these on the network.
Speed of named pipe vs tcp/ip vs shared memory; Named Pipe communication between two terminals; Named Pipes Client in MQL4 and Server in C++; 40886.

Here's how you find the port number that's being used by TCP/IP on your machine: Open the SQL Server Configuration Manager. Expand SQL Server Network Configuration and select Protocols for <INSTANCE_NAME>. Double-click on TCP/IP and make sure Enabled is set to Yes. Remember whether Listen All is set to Yes or No and switch to the IP Addresses tab.
In the TCP/IP Properties dialog select the IP Addresses tab and scroll down to IPAII. Set the TCP Dynamic Ports to blank and TCP Port to 1434, and restart the SQL Server<server name> service. When connecting to a SQL Server named instance SQL Server Browser claims the UDP port 1434.
In computing, a named pipe (also known as a FIFO for its behavior) 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).
Sep 12, 2019 · Named Pipes vs. TCP/IP Sockets. In a fast-local area network (LAN) environment, Transmission Control Protocol/Internet Protocol (TCP/IP) Sockets and Named Pipes clients are comparable with regard to performance.
In a nutshell, does a named pipe offer the same performance as regular pipes? Or does it have the overhead of hardisk access? Named pipes do not access the hard disk.

RE: Named Pipes vs TCP/IP in Citrix environment Dukester0122 (IS/IT--Management) 7 Dec 06 16:54 Let me just clarify your statement, when you go to ODBC Data Source Administrator in your Citrix server and open the DSN then go to Client Configuration.
When checking the clients ODBC settings they were set to connect using TCP/IP (just like the other 30 odd clients that are still successfully connecting). I changed the connection protocol to named pipes and the faulting workstations connected instantly.
Named Pipes, Fifos Under Unix as well as under Linux it's possible to create Pipes, which are implemented as files. These Pipes are called "named pipes" or sometimes Fifos (First In First Out). A process reads from and writes to such a pipe as if it were a regular file.

Named pipes have features not unlike TCP connections, but there are important differences. Because a fifo has a persistent filesystem name you can write to it even when there is no reader, admittedly the writes will block (without async or non-blocking I/O), though you won't loose data if the receiver isn't started (or is being restarted). This API provides interfaces to raw UDP sockets, TCP Client sockets and TCP Server sockets. As such, this requires a high level of trust in applications that use this API, since raw sockets can be used to work around the same origin security policy.
