The Line Printer Daemon protocol/Line Printer Remote protocol (or LPD, LPR) is a network printing protocol for submitting print jobs to a remote printer. The original implementation of LPD was in the Berkeley printing system in the BSD UNIX operating system; the LPRng project also supports that protocol. The Common Unix Printing System (or CUPS), which is more common on modern Linux distributions and also found on Mac OS X, supports LPD as well as the Internet Printing Protocol (IPP). Commercial solutions are available that also use Berkeley printing protocol components, where more robust functionality and performance is necessary than is available from LPR/LPD (or CUPS) alone (such as might be required in large corporate environments). The LPD Protocol Specification is documented in RFC 1179.

Port mirroring is used on a network switch to send a copy of network packets seen on one switch port (or an entire VLAN) to a network monitoring connection on another switch port. This is commonly used for network appliances that require monitoring of network traffic such as an intrusion detection system, passive probe or real user monitoring (RUM) technology that is used to support application performance management (APM). Port mirroring on a Cisco Systems switch is generally referred to as Switched Port Analyzer (SPAN) or Remote Switched Port Analyzer (RSPAN). Other vendors have different names for it, such as Roving Analysis Port (RAP) on 3Com switches.

Network engineers or administrators use port mirroring to analyze and debug data or diagnose errors on a network. It helps administrators keep a close eye on network performance and alerts them when problems occur. It can be used to mirror either inbound or outbound traffic (or both) on single or multiple interfaces.

The Global Information Grid (GIG) is a network of information transmission and processing maintained by the United States Department of Defense. More descriptively, it is a worldwide network of information transmission, of associated processes, and of personnel serving to collect, process, safeguard, transmit, and manage this information. It is an all-encompassing communications project of the United States Department of Defense. The GIG makes this immediately available to military personnel, to those responsible for military politics, and for support personnel. It includes all infrastructure, bought or loaned, of communications, electronics, informatics (including software and databases), and security. It is the most visible manifestation of network-centric warfare. It is the combination of technology and human activity that enables warfighters to access information on demand.

It is defined as a "globally interconnected, end-to-end set of information capabilities for collecting, processing, storing, disseminating, and managing information on demand to warfighters, policy makers, and support personnel".

The GIG includes owned and leased communications and computing systems and services, software (including applications), data, security services, other associated services, and National Security Systems. Non-GIG Information Technology (IT) includes stand-alone, self-contained, or embedded IT that is not, and will not be, connected to the enterprise network.

This new definition removes references to the National Security Systems as defined in section 5142 of the Clinger-Cohen Act of 1996. Further, this new definition removes the references to the GIG providing capabilities from all operating locations (bases, posts, camps, stations, facilities, mobile platforms, and deployed sites). And lastly, this definition removes the part of the definition that discusses the interfaces to coalition, allied, and non-Department of Defense users and systems.

The DoD's use of the term "GIG" is undergoing changes as the Department deals with new concepts such as Cyberspace Operations, GIG 2.0 (A Joint Staff J6 Initiative), and the Department of Defense Information Enterprise (DIE).

The GIG is managed by a construct known as NetOps. NetOps is defined as the operational framework consisting of three essential tasks, Situational Awareness (SA), and Command & Control (C2) that the Commander (CDR) of United States Strategic Command (USSTRATCOM), in coordination with DoD and Global NetOps Community, employs to operate and defend the GIG to ensure information superiority.

Web Cache Communication Protocol (WCCP) is a Cisco-developed content-routing protocol that provides a mechanism to redirect traffic flows in real-time. It has built-in load balancing, scaling, fault tolerance, and service-assurance (failsafe) mechanisms. Cisco IOS Release 12.1 and later releases allow the use of either Version 1 (WCCPv1) or Version 2 (WCCPv2) of the protocol.

WCCP allows utilization of Cisco Cache Engines (or other caches running WCCP) to localize web traffic patterns in the network, enabling content requests to be fulfilled locally. Traffic localization reduces transmission costs and download time.

The International Cable Protection Committee (ICPC) is a submarine cable protection non-profit organization. It was formed in 1958 to promote the protection of international telecommunications and power submarine cables against human and natural hazards. It provides a forum for the exchange of technical, legal, and environmental information about submarine cables and engages with stakeholders and governments globally to promote submarine cable protection. The ICPC has approximately 170 Members from over 60 nations, including cable operators, owners, manufacturers, industry service providers, as well as governments. The ICPC provides information related to submarine cables generally, best practices for cable protection, and applicable international law and treaties.

Nearly 100% of the world's intercontinental electronic communications traffic is carried by the undersea cable infrastructure. Likewise, submarine power cables underpin the global expansion of offshore renewable energy generation. As such, the impact of failures of these critical telecommunications and power cables can be devastating to social and economic stability. This is why submarine cables are classified as "critical infrastructure" that is to be protected from physical damage due to manmade or natural causes.

Real-Time Messaging Protocol (RTMP) is a communication protocol for streaming audio, video and data over the Internet. Originally developed as a proprietary protocol by Macromedia for streaming between a Flash player and a server, Adobe (which acquired Macromedia) has released an incomplete version of the specification of the protocol for public use.

The RTMP protocol has multiple variations:

While the primary motivation for RTMP was to be a protocol for playing Flash video, it is also used in some other applications, such as the Adobe LiveCycle Data Services ES.

The Intelligent Platform Management Interface (IPMI) is a set of computer interface specifications for an autonomous computer subsystem that provides management and monitoring capabilities independently of the host system's CPU, firmware (BIOS or UEFI) and operating system. IPMI defines a set of interfaces used by system administrators for out-of-band management of computer systems and monitoring of their operation. For example, IPMI provides a way to manage a computer that may be powered off or otherwise unresponsive by using a network connection to the hardware rather than to an operating system or login shell. Another use case may be installing a custom operating system remotely. Without IPMI, installing a custom operating system may require an administrator to be physically present near the computer, insert a DVD or a USB flash drive containing the OS installer and complete the installation process using a monitor and a keyboard. Using IPMI, an administrator can mount an ISO image, simulate an installer DVD, and perform the installation remotely.

The specification is led by Intel and was first published on September 16, 1998. It is supported by more than 200 computer system vendors, such as Cisco, Dell, Hewlett Packard Enterprise, Intel, OnLogic, Marvell Semiconductor, NEC Corporation, Supermicro and Tyan.

The successor to the IPMI is Redfish.

Direct Access File System (DAFS) is anetwork file system that is based on NFSv4 and the Virtual Interface (VI) data transfer mechanism. DAFS uses remote direct memory access (RDMA) to perform efficient network access to data in remote files. This lowers latency by reducing the number of steps needed to process and transfer remote data. File locking is cached on the client side, eliminating the need to access the file server for subsequent data access.

The DAFS was initially developed by Network Appliance Inc. An 85-member industry association named the DAFS Collaborative was assembled to complete the specification. With the draft release of v1.0, it was then passed to the Internet Engineering Task Force (IETF). Version 1.0 of the DAFS application programming interface was completed in 2001. The same year, a working version of DAFS was demonstrated using the Oracle database. DAFS beta version 1.0 is available from SourceForge under the BSD license. It was last updated in 2004.
