The port numbers in the range from 0 to 1023 (0 to 2 10 − 1) are the well-known ports or system ports. [3] They are used by system processes that provide widely used types of network services. On Unix-like operating systems, a process must execute with superuser privileges to be able to bind a network socket to an IP address using one of the ...
Sun Microsystems Cascade, which became known as PC-Netlink, represents a port of Advanced Server for Unix. Sun took over two years making the code useful, due to the poor quality of the original port. [citation needed] Novell NetWare version 6 and newer has a CIFS server implementation providing access to NetWare volumes for Microsoft Network ...
The most common transport protocols that use port numbers are the Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP); those port numbers are 16-bit unsigned numbers. A port number is always associated with a network address of a host, such as an IP address, and the type of transport protocol used for communication. It ...
This article lists protocols, categorized by the nearest layer in the Open Systems Interconnection model.This list is not exclusive to only the OSI protocol family.Many of these protocols are originally based on the Internet Protocol Suite (TCP/IP) and other models and they often do not fit neatly into OSI layers.
In 1996, Microsoft published a version of SMB 1.0 [4] with minor modifications under the Common Internet File System (CIFS / s ɪ f s /) moniker. CIFS was compatible with even the earliest incarnation of SMB, including LAN Manager's. [4] It supports symbolic links, hard links, and larger file size, but none of the features of SMB 2.0 and later.
UPnP logo as promoted by the UPnP Forum (2001–2016) and Open Connectivity Foundation (2016–present). Universal Plug and Play (UPnP) is a set of networking protocols on the Internet Protocol (IP) that permits networked devices, such as personal computers, printers, Internet gateways, Wi-Fi access points and mobile devices, to seamlessly discover each other's presence on the network and ...
It is also a concept used in Queueing Network Analyzers (QNAs) or in packet tracing. Applied to Internet routers, a flow may be a host-to-host communication path, or a socket-to-socket communication identified by a unique combination of source and destination addresses and port numbers, together with transport protocol (for example, UDP or TCP).
Port numbers are categorized into three basic categories: well-known, registered, and dynamic or private. The well-known ports are assigned by the Internet Assigned Numbers Authority (IANA) and are typically used by system-level processes. Well-known applications running as servers and passively listening for connections typically use these ports.
