GL-15
protocol: A set of rules for communication, sometimes made up of
several smaller sets of rules also called protocols. AppleTalk is a
protocol that includes the LocalTalk, EtherTalk, and TokenTalk
protocols.
Q.922 A (Q.922 Annex A): The international draft standard that
defines the structure of frame relay frames. Based on the Q.922A
frame format developed by the CCITT. All frame relay frames
entering a frame relay network automatically confiorm to this
structure. Contrast with LAPB (Link Access Procedure Balanced).
Q.922 A Frame: A variable-length unit of data, formatted in
frame-relay (Q.922A) format, that is transmitted through a frame
relay network as pure data (i.e., it contains no flow control
information). Contrast with Packet. See also
Frame Relay Frame.
remapping: See network number remapping.
RFC (Request for Comment): A series of documents used to
exchange information and standards about the Internet.
RIP (Routing Information Protocol): A protocol used for the
transmission of IP routing information.
RJ-11: A telephone-industry standard connector type, usually
containing four pins.
RJ-45: A telephone-industry standard connector type usually
containing eight pins.
router: A device that supports LAN-to-LAN communications. A
router can connect identical network types, such as
LocalTalk-to-LocalTalk, or dissimilar network types, such as
LocalTalk-to-Ethernet. However—unless a gateway is available—a
common protocol, such as AppleTalk, must be used over both
networks. Routers may be equipped to provide frame relay or ISDN
line support to the LAN devices they serve. A frame-relay-capable
router encapsulates LAN frames in frame relay frames and feeds
those frames to a frame relay switch for transmission across the
network. See also
Bridge and gateway.
