Frame Relay

<communications> A DTE-DCE interface specification based on LAPD (Q.921), the Integrated Services Digital Network version of LAPB (X.25 data link layer). A common specification was produced by a consortium of StrataCom, Cisco, Digital, and Northern Telecom. Frame Relay is the result of wide area networking requirements for speed; LAN-WAN and LAN-LAN internetworking; "bursty" data communications; multiplicity of protocols and protocol transparency. These requirements can be met with technology such as {optical fibre} lines, allowing higher speeds and fewer transmission errors; intelligent network end devices (personal computers, workstations, and servers); standardisation and adoption of ISDN protocols. Frame Relay could connect dedicated lines and X.25 to ATM, SMDS, BISDN and other "fast packet" technologies. Frame Relay uses the same basic data link layer framing and Frame Check Sequence so current X.25 hardware still works. It adds addressing (a 10-bit Data Link Connection Identifier (DLCI)) and a few control bits but does not include retransmissions, link establishment, windows or error recovery. It has none of X.25's session layer but adds some simple interface management. Any network layer protocol can be used over the data link layer Frames. {Frame Relay Resource Center (http://alliancedatacom.com/framerelay.asp)}. (2000-07-14)

Frame Relay assembler/disassembler

Frame Relay Assembler/Disassembler; Frame relay assembler/disassembler

A FRAD (Frame Relay access device or Frame Relay assembler/disassembler) is a device that turns data packets into Frame Relay frames that can be sent over a Frame Relay network and turns the received Frame Relay frames into data packets. Its assembly and disassembly functionality is similar to a packet assembler/disassembler (PAD), which is used for accessing X.

Hive frame

STRUCTURAL ELEMENT IN A BEEHIVE

Beehive frame; Frame (beehive); Honey frame

A hive frame or honey frame is a structural element in a beehive that holds the honeycomb or brood comb within the hive enclosure or box. The hive frame is a key part of the modern movable-comb hive.

Frame Relay

Frame Relay is a standardized wide area network (WAN) technology that specifies the physical and data link layers of digital telecommunications channels using a packet switching methodology. Originally designed for transport across Integrated Services Digital Network (ISDN) infrastructure, it may be used today in the context of many other network interfaces.

Network providers commonly implement Frame Relay for voice (VoFR) and data as an encapsulation technique used between local area networks (LANs) over a WAN. Each end-user gets a private line (or leased line) to a Frame Relay node. The Frame Relay network handles the transmission over a frequently changing path transparent to all end-user extensively used WAN protocols. It is less expensive than leased lines and that is one reason for its popularity. The extreme simplicity of configuring user equipment in a Frame Relay network offers another reason for Frame Relay's popularity.

With the advent of Ethernet over fiber optics, MPLS, VPN and dedicated broadband services such as cable modem and DSL, Frame Relay has become less popular in recent years.
