The ATM network reference model approximately maps to the three lowest layers of the OSI model: physical layer, data link layer, and network layer. [7] ATM is a core protocol used in the synchronous optical networking and synchronous digital hierarchy (SONET/SDH) backbone of the public switched telephone network and in the Integrated Services ...
An internetwork is the connection of multiple different types of computer networks to form a single computer network using higher-layer network protocols and connecting them together using routers. The Internet is the largest example of internetwork. It is a global system of interconnected governmental, academic, corporate, public, and private ...
A computer network diagram is a schematic depicting the nodes and connections amongst nodes in a computer network or, more generally, any telecommunications network. Computer network diagrams form an important part of network documentation.
ATM Adaptation Layer 2 (AAL2) is an Asynchronous Transfer Mode (ATM) adaptation layer, used primarily in telecommunications; for example, it is used for the Iu interfaces in the Universal Mobile Telecommunications System, and is also used for transporting digital voice. The standard specifications related to AAL2 are ITU standards I.363.2 and ...
IDT 77155, a 155 Mbit/s ATM SAR controller chip. Segmentation and reassembly (SAR) is the process used to fragment and reassemble variable length packets into fixed length cells so as to allow them to be transported across Asynchronous Transfer Mode (ATM) networks or other cell based infrastructures. Since ATM's payload is only 48 bytes, nearly ...
FORE Systems, Inc., was a computer network switching equipment company based in Pittsburgh, Pennsylvania.Founded in 1990 to supply Asynchronous Transfer Mode (ATM) cards for workstation computers, it soon branched out to become a major supplier in the ATM switch market and the extended those product lines to add Internet Protocol switching and other devices.
For example, in ATM networks, in the form of the generic cell rate algorithm, it is used to compare the bandwidth and burstiness of traffic on a virtual channel (VC) or virtual path (VP) against the specified limits on the rate at which cells may arrive and the maximum jitter, or variation in inter-arrival intervals, for the VC or VP.
Conformance to this BAG (and maximum transmission jitter) is then checked in the network switches in a similar way to UPC in ATM networks. However, the token bucket algorithm is recommended for AFDX, and a version that allows for variable length frames (one that counts bytes) is preferred over one that only counts frames and assumes that all ...
