A Petri Net Model for FDDI

1997
Reports

Abstract

Fiber Distributed Data Interface (FDDI) is a high speed local area network operating at 100Mbps using a fiber optic ring transmission medium. The purpose of this paper is to build a Petri net model for the FDDI media access control (MAC) protocol. This model is hierarchically integrated into the Petri net model of the two-phase commitment (2PC) algorithm. By simulating the composed Petri net model we evaluate the latency of the 2PC algorithm. The FDDI model is validated by comparing the data obtained from performance measures and the numerical results derived from simulation.

Fiber Distributed Data Interface

Fiber Distributed Data Interface (FDDI) is a standard for data transmission in a local area network. It uses optical fiber as its standard underlying physical medium, although it was also later specified to use copper cable, in which case it may be called CDDI (Copper Distributed Data Interface), standardized as TP-PMD (Twisted-Pair Physical Medium-Dependent), also referred to as TP-DDI (Twisted-Pair Distributed Data Interface).

Medium access control

In IEEE 802 LAN/MAN standards, the medium access control (MAC, also called media access control) sublayer is the layer that controls the hardware responsible for interaction with the wired, optical or wireless transmission medium. The MAC sublayer and the logical link control (LLC) sublayer together make up the data link layer. The LLC provides flow control and multiplexing for the logical link (i.e. EtherType, 802.1Q VLAN tag etc), while the MAC provides flow control and multiplexing for the transmission medium.

Data link layer

The data link layer, or layer 2, is the second layer of the seven-layer OSI model of computer networking. This layer is the protocol layer that transfers data between nodes on a network segment across the physical layer. The data link layer provides the functional and procedural means to transfer data between network entities and may also provide the means to detect and possibly correct errors that can occur in the physical layer. The data link layer is concerned with local delivery of frames between nodes on the same level of the network.
