AppleTalk is a discontinued proprietary suite of networking protocols developed by Apple Computer for their Macintosh computers. AppleTalk includes a number of features that allow local area networks to be connected with no prior setup or the need for a centralized router or server of any sort. Connected AppleTalk-equipped systems automatically assign addresses, update the distributed namespace, and configure any required inter-networking routing.
Wake-on-LAN is an Ethernet or Token Ring computer networking standard that allows a computer to be turned on or awakened from sleep mode by a network message.
A network operating system (NOS) is a specialized operating system for a network device such as a router, switch or firewall.
Xerox Network Systems (XNS) is a computer networking protocol suite developed by Xerox within the Xerox Network Systems Architecture. It provided general purpose network communications, internetwork routing and packet delivery, and higher level functions such as a reliable stream, and remote procedure calls. XNS predated and influenced the development of the Open Systems Interconnection (OSI) networking model, and was very influential in local area networking designs during the 1980s.
The Address Resolution Protocol (ARP) is a communication protocol used for discovering the link layer address, such as a MAC address, associated with a given internet layer address, typically an IPv4 address. This mapping is a critical function in the Internet protocol suite. ARP was defined in 1982 by RFC 826, which is Internet Standard STD 37.
LocalTalk is a particular implementation of the physical layer of the AppleTalk networking system from Apple Computer.
GeoPort is a serial data system used on some models of the Apple Macintosh that could be externally clocked to run at a 2 megabit per second data rate. GeoPort slightly modified the existing Mac serial port pins to allow the computer's internal DSP hardware or software to send data that, when passed to a digital-to-analog converter, emulated various devices such as modems and fax machines. GeoPort could be found on late-model 68K-based machines as well as many pre-USB Power Macintosh models and PiPPiN. Some later Macintosh models also included an internal GeoPort via an internal connector on the Communications Slot. Apple GeoPort technology is now obsolete, and modem support is typically offered through USB.
A broadcast address is a network address used to transmit to all devices connected to a multiple-access communications network. A message sent to a broadcast address may be received by all network-attached hosts.
AppleShare is a discontinued product from Apple Computer which implements various network services. Its main purpose is to act as a file server, using the AFP protocol. Other network services implemented in later versions of AppleShare included a print server using the Printer Access Protocol (PAP), web server, electronic mail server, and SMB / CIFS server to support file sharing to Microsoft Windows clients.
AppleTalk Remote Access, or ARA, was a protocol stack that allowed AppleTalk to be run over modems. It became a fairly major product for Apple Computer in the early to mid-1990s when their first portable and laptop computers were available. ARA slowly disappeared in the late 1990s when TCP/IP took over the vast majority of networking needs, notably remote access.
A LocalTalk-to-Ethernet Bridge is a network bridge that joins the physical layer of the AppleTalk networking used by previous generations of Apple Computer products to an Ethernet network. This was an important class of products in the late 1980s and early 1990s, before Ethernet support became universal on the Mac lineup.
MacIP refers to a standard for encapsulating Internet Protocol (IP) packets within the AppleTalk DDP protocol. This allows Macintosh computers with LocalTalk networking hardware to access the normally Ethernet-based connections for TCP/IP based network services. This was an important bridging technology during the era when Ethernet and TCP/IP were rapidly growing in popularity in the early 1990s.
The GatorBox is a LocalTalk-to-Ethernet bridge, a router used on Macintosh-based networks to allow AppleTalk communications between clients on LocalTalk and Ethernet physical networks. The GatorSystem software also allowed TCP/IP and DECnet protocols to be carried to LocalTalk-equipped clients via tunneling, providing them with access to these normally Ethernet-only systems.
The Macintosh Office was an effort by Apple Computer to design an office-wide computing environment consisting of Macintosh computers, a local area networking system, a file server, and a networked laser printer. Apple announced Macintosh Office in January 1985 with a poorly received sixty-second Super Bowl commercial dubbed Lemmings. In the end, the file server would never ship and the Office project would be cancelled. However, the AppleTalk networking system and LaserWriter printer would be hugely successful in launching the desktop publishing revolution.
TOPS is a peer-to-peer LAN-based file sharing system best known in its Macintosh implementation, but also available for DOS and able to interoperate with Unix's NFS. Originally written by Centram Systems West, the company was purchased by Sun Microsystems as part of Sun's development of the NFS ecosystem. The Centram company was renamed to TOPS after its acquisition by Sun. Sales of TOPS dried up after the introduction of System 7, which featured a similar file sharing system built-in, and Sun spun off their NFS developments to Sitka.
Kinetics Internet Protocol (KIP) is a network protocol used for the encapsulation and routing of AppleTalk data packets over IP. It also controls the routing tables.
Excelan was a computer networking company founded in 1982 by Kanwal Rekhi, Inder Singh and Navindra Jain. Excelan was a manufacturer of smart Ethernet cards, until the company merged with, and was acquired by Novell in 1989. The company offered a line of Ethernet "front end processor" boards for Multibus, VMEbus, Q-Bus, Unibus, and IBM AT Bus systems. The cards were equipped with their own processor and memory, and ran TCP/IP protocol software that was downloaded onto the cards from the host system. Excelan offered software like LAN Workplace that integrated the cards into a variety of operating system environments, including many flavors of UNIX, RSX-11, VMS, and DOS. The hardware and software were sold under the EXOS brand. In 1987, Excelan also acquired Kinetics, a small networking company that manufactured and sold a variety of Ethernet networking products for Apple Macintosh environments, most notably an AppleTalk-to-Ethernet gateway called the FastPath.
The Power Macintosh 6400 is a personal computer designed, manufactured and sold by Apple Computer from August 1996 to August 1997. It is the only Macintosh mini-tower system to be branded as a Performa, and alongside the Performa 6360 was the last new Performa-branded model introduced by Apple.
RTP-MIDI is a protocol to transport MIDI messages within Real-time Transport Protocol (RTP) packets over Ethernet and WiFi networks. It is completely open and free, and is compatible both with LAN and WAN application fields. Compared to MIDI 1.0, RTP-MIDI includes new features like session management, device synchronization and detection of lost packets, with automatic regeneration of lost data. RTP-MIDI is compatible with real-time applications, and supports sample-accurate synchronization for each MIDI message.
SoftEther VPN is free open-source, cross-platform, multi-protocol VPN client and VPN server software, developed as part of Daiyuu Nobori's master's thesis research at the University of Tsukuba. VPN protocols such as SSL VPN, L2TP/IPsec, OpenVPN, and Microsoft Secure Socket Tunneling Protocol are provided in a single VPN server. It was released using the GPLv2 license on January 4, 2014. The license was switched to Apache License 2.0 on January 21, 2019.
