See BOC. RCP See "Remote copy program" Read the Fantastic Manual (RTFM) Source: zen Index: This anacronym is often used when someone asks a simple or common question. The word `Fantastic' is usually re- placed with one much more vulgar. Remote Copy Program Source: nnsc Index: protocol,application A program based on the Berkeley UNIX (see BSD) rcmd protocol that permits files to be copied from one computer to another by an extension to the syntax of the UNIX cp (copy) command. This protocol is widely implemented on UNIX machines, but the protocol is general enough that non-UNIX machines may use it. However, rcp does not provide the word-length adaptability and flexibility that the FTP protocol does. Remote Procedure Call (RPC) Source: rfc1208 Index: protocol An easy and popular paradigm for implementing the client-server model of distributed computing. In general, a request is sent to a remote system to execute a designated procedure, using arguments supplied, and the result returned to the caller. There are many variations and subtleties in various implementations, resulting in a variety of different (incompatible) RPC protocols. repeater Source: rfc1208 Index: network A device which propagates electrical signals from one cable to another without making routing decisions or providing packet filtering. In OSI terminology, a repeater is a Physical Layer intermediate system. See also bridge and router. On an ethernet, repeaters are used to connect two or more segments of cable together. The repeater retimes and reamplifies the signal received on one segment before resending it on all other segments. Request For Comments (RFC) Source: hacker Index: The document series, begun in 1969, which describes the Internet suite of protocols and related experiments. Not all (in fact very few) RFCs describe Internet stan- dards, but all Internet standards are written up as RFCs. The RFC series of documents are unusual in that the proposed protocols are forwarded by the Internet research and development community, acting on their own behalf, as opposed to the formally reviewed and standardized protocols that are promoted by organizations such as CCITT and ANSI. Reseaux Associes pour la Recherche Europeenne (RARE) Source: rfc1208 Index: network European association of research networks. Reseaux IP Europeenne (RIPE) Source: rfc1208 Index: network European continental TCP/IP network operated by EUnet. See EUnet. resolver Source: Index: Definition: Reverse Address Resolution Protocol (RARP) Source: malamud Index: protocol A TCP/IP protocol which provides the reverse function of ARP. RARP maps a physical (hardware) address to an Internet address. Often used by diskless nodes when they first initialize to find their Internet address. RFC 822 Source: comer Index: protocol The TCP/IP standard format for electronic mail mes- sage headers. Mail experts often refer to "822 messages." The name comes from RFC 822 that contains the specifica- tion. 822 format was previously known as 733 format. RFC See "Request For Comments" RIP See "Routing Information Protocol" RIPE See "Reseaux IP Europeenne" rlogin Source: nnsc Index: protocol,application A program based on the Berkeley UNIX (see BSD) rcmd protocol that permits a user on one computer to log in to another computer. This protocol is widely implemented among UNIX machines, but the protocol is general enough that non-UNIX machines may use it. For example, Excelan ANNEX terminal concentrators permit users on dumb terminals to use the rlogin protocol to communicate with Internet computers. Round-Trip Time (RTT) Source: malamud Index: A measure of the current delay on a network. route Source: orig Index: general The path that network traffic takes from its source to its destination. Also, a possible path from a given host to another host or destination. routed Source: orig Index: application,unix Route Daemon. A program that runs under 4.2BSD/4.3BSD UNIX systems (and derived operating systems) to pro- pagate routes among machines on a local area network, using the RIP protocol. Pronounced "route-d". router Source: nnsc Index: A device that attempts to choose the best network route for a packet from a group of routes available. This is a generic term and applies to such diverse devices as bridges, lan routers and WAN gateways. Bridges are a primitive form of router that chooses whether or not it will pass packets from one physical network to another. Routers may do fragmentation and reassembly of packets, as necessary. A router is often a special-purpose dedicated computer, to ensure reliability. Routers operate at OSI Level 3, the Network Layer. Routing Domain Source: malamud Index: A set of hosts and routers which operate according to the same routing procedures and which is wholly con- tained within a single administrative domain. Routing Information Protocol (RIP) Source: nnsc Index: protocol An Interior Gateway Protocol provided in the Berkeley UNIX (see BSD) operating system, that permits a group of hosts located on a local network to share routing information. This function is typically provided by the program routed. RIP is used on many LANs and on some of the NSFnet regional networks. Routing Protocol Source: big-lan Index: A protocol sent between routers by which routers ex- change information own how to route to various parts of the network. The TCP/IP family of protocols has a bunch, such as RIP, EGP, BGP, OSPF, and dual IS-IS. routing Source: orig Index: general The process of selecting the correct path (circuit) for a transmission over a network. RPC See "Remote Procedure Call" RTFM See "Read the Fantastic Manual" RTT See "Round-Trip Time" SCALE Source: malamud Index: The TCP window scaling option defined in RFC 1072. Allows window information to be interpreted as being scaled by 1 to 16 powers of 2, thus increasing the size of the effective window. Also, used to indicate growth in computer systems and applicabilty of solutions to larger networks than it is currently working under (e.g. "How well does Kerberos scale to 10,000 users?") Serial Line IP (SLIP) Source: rfc1208 Index: protocol A defacto protocol used to run IP over serial lines such as telephone circuits or RS-232 cables interconnecting two systems. SLIP is now being replaced by PPP. See also Point-to-Point Protocol. SLIP is not an Internet standard but is defined in RFC 1055. server Source: sura Index: general A provider of resources. In a networking context, one often speaks of fileservers (which provide files to client machines), nameservers (which provide address to name lookups, and vice-versa) and other miscellaneous servers. SIG See "Special Interest Group" signature Source: zen Index: The small, usually four-line message at the bottom of a piece of email or a Usenet article. In Unix, it's added by creating a file `.signature' in the user's home directory. Large signatures are a no-no. Simple Mail Transfer Protocol (SMTP) Source: big-lan Index: protocol The protocol in the TCP/IP family used to transfer electronic mail between computers. SMTP mail follows RFC-822 closely. SMTP specifies how two mail systems interact and the format of control messages they exchange to transfer mail. It is not oriented towards a client/server system so other protocols (see "POP") are often used in that context. However, servers will generally use SMTP if they need to transfer a mes- sage to another server. Simple Network Management Protocol (SNMP) Source: big-lan Index: protocol Originally developed to manage IP based network equip- ment like routers and bridges, now extended to wiring hubs, workstations, toasters, jukeboxes, etc. SNMP for IPX and AppleTalk under development. Widely implement- ed. This protocol is defined in RFC 1098. See CMIP. SLIP See "Serial Line IP" SMDS See "Switched Multimegabit Data Service" SMI See "Structure of Management Information" SMTP See "Simple Mail Transfer Protocol" SNA See "Systems Network Architecture" snail mail Source: malamud Index: The traditional postal service. SNMP See "Simple Network Management Protocol" SPAG See "Standards Promotion and Applications Group" Special Interest Group Source: ethics Index: A group of respondents within an electronic mail system that limit communications within the group to a partic- ular subject matter. It is usually preferable to have a leader or coordinator of the group to perform editing, filtering, collection, and administrative functions (such as maintaining a message archive) for the group. split horizon Source: hgi Index: When a router (or group of routers working in consort) accept routing information from multiple external net- works, but do not pass on information learned from one external network to any others. This is an attempt to prevent bogus routes to a network from being propagated because of gossip or counting to infinity. Standards Promotion and Applications Group (SPAG) Source: nnsc Index: organization This European organization collaborates with Corpora- tion for Open Systems (COS) (need COS definition???) to promote testing procedures and techniques for OSI pro- ducts. stream-oriented Source: malamud Index: A type of transport service that allows its client to send data in a continuous stream. The transport ser- vice will guarantee that all data will be delivered to the other end in the same order as sent and without du- plicates. Also known as a reliable transport service. Structure of Management Information (SMI) Source: rfc1208 Index: protocol The rules used to define the objects that can be accessed via a network management protocol. This protocol is defined in RFC 1155. See MIB. subnet address Source: cs-gloss Index: An extension of the Internet addressing system that al- lows a site to subdivide a single Internet address to cover multiple physical net works. This is done by di- viding up the host address part of an IP address into a local network number and host address number. subnet field Source: malamud Index: The bit field in an internet address denoting the sub- net number. The bits making up this field are not necessarily contiguous in the address. [RFC 950] subnet mask Source: rfc1208 Index: address type See address mask. subnet number Source: fyi4 Index: address type A part of the internet address which designates a sub- net. It is ignored for the purposes internet routing, but is used for intranet routing. subnet Source: malamud Index: A term used to denote any networking technology that makes all nodes connected to it appear to be one hop away. In other words, the user of the subnet can com- municate directly to all other nodes on the subnet. A subnet could be X.25, Ethernet, a token ring, ISDN, or a point-to-point link. A collection of subnets, to- gether with a routing or network layer, combine to form a network. subnetting Source: fyi4 Index: A portion of a network, which may be a physically in- dependent network, which shares a network address with other portions of the network and is distinguished by a subnet number. A subnet is to a network what a network is to an internet. Switch See "packet switch" Switched Multimegabit Data Service (SMDS) Source: rfc1208 Index: protocol An emerging high-speed datagram-based public data network service developed by Bellcore and expected to be widely used by telephone companies as the basis for their data networks. Systems Network Architecture (SNA) Source: nnsc Index: A proprietary networking architecture used by IBM and IBM-compatible mainframe computers. Because of its widespread use, SNA is a defacto standard. While it can use packet switched networks for transport, SNA is largely a circuit-switched rather than a packet- switching technology. "e
