This part of ISO\/IEC 9314 specifies the Station Management (SMT) for the Fibre Distributed Data<\/p>\n
Interface (FDDI).<\/p>\n
FDDI provides a high bandwidth (100 megabits per second) general purpose interconnection among<\/p>\n
computers and peripheral equipment using optical fibre as the transmission medium in a ring<\/p>\n
configuration. FDDI can be configured to support a sustained transfer rate of approximately<\/p>\n
80 megabits (10 megabytes) per second. The use of dual attachment stations with dual MACs allows<\/p>\n
these rates to be doubled under the circumstance of a fault-free FDDI ring.<\/p>\n
FDDI establishes the connection among many stations (nodes) distributed over distances of several<\/p>\n
kilometres in extent. Default values for FDDI were calculated on the basis of 1 000 physical<\/p>\n
connections and a total fibre path length of 200 km.<\/p>\n
The FDDI consists of<\/p>\n
a) A Physical Layer (PL), which provides the medium, connectors, optical bypassing,<\/p>\n
and driver\/receiver requirements. PL also defines encode\/decode and clock<\/p>\n
requirements as required for framing the data for transmission on the medium or to<\/p>\n
the higher layers of the FDDI. For the purposes of this part of ISO\/IEC 9314,<\/p>\n
references to the PL are made in terms of the Physical Layer protocol (PHY) and the<\/p>\n
Physical Layer Media Dependent (PMD) entities which are the upper and lower<\/p>\n
sublayers of PL, respectively.<\/p>\n
b) A Data Link Layer (DLL) which controls the accessing of the medium and the<\/p>\n
generation and verification of frame check sequences to assure the proper delivery<\/p>\n
of valid data to the higher layers. DLL also concerns itself with the generation and<\/p>\n
recognition of device addresses and the peer-to-peer associations within the FDDI<\/p>\n
network. For the purposes of this part of ISO\/IEC 9314, references to the DLL are<\/p>\n
made in terms of the Media Access Control (MAC) entity which is the lowest<\/p>\n
sublayer of DLL.<\/p>\n
c) A Station Management (SMT) standard, this part of ISO\/IEC 9314, which provides<\/p>\n
the control necessary at the station (node) level to manage the processes underway<\/p>\n
in the various FDDI layers such that a station may work cooperatively as a part of<\/p>\n
an FDDI network. SMT shall provide services such as connection management,<\/p>\n
station insertion and removal, station initialization, configuration management, fault<\/p>\n
isolation and recovery, communications protocol for external authority, scheduling<\/p>\n
policies, and collection of statistics.<\/p>\n
The definition of SMT as contained herein includes the set of services that it provides for, and receives<\/p>\n
from, the other entities that are contained within a node. Within SMT resides both knowledge of the<\/p>\n
uniqueness of this node and the current network structure to the extent that this node's function is<\/p>\n
affected.<\/p>\n
The set of International Standards for FDDI, ISO\/IEC 9314, specifies the interfaces, functions and<\/p>\n
operations necessary to insure interoperability between conforming FDDI implementations. This part<\/p>\n
of ISO\/IEC 9314 is a functional description. Conforming implementations may employ any design<\/p>\n
technique which does not violate interoperability.<\/p>\n","protected":false},"excerpt":{"rendered":"
