34、urpose multi-node network and is designed for efficient operation with a peak data rate of100Mbit/s. It uses a Token Ring architecture with optical fibre as the transmission medium. FDDI provides for hundreds of nodes operating over an extent of tens of kilometres. Station Management (SMT) specifies
35、 the local portion of the system management application process for FDDI, including the control required for proper operation of a node in an FDDI ring. SMT provides services such as connection management, station insertion and removal, station initialization, configuration management, fault isolati
36、on and recovery, communications protocol for external authority, scheduling policies, and collection of statistics. When the set of basic FDDI standards, ISO/IEC9314, is completed it will include the following standards: a) A Media Access Control (MAC), which specifies the lower sublayer of the Data
37、 Link Layer of ISO/IEC9314, b) A Physical Layer Media Dependent (PMD), which specifies the lower sublayer of the Physical Layer of ISO/IEC9314, c) A Physical Layer Protocol (PHY), which specifies the upper sublayer of the Physical Layer of ISO/IEC9314. A number of extensions to ISO/IEC9314 are compl
38、eted or in process. One extension, ISO/IEC9314-5, for Hybrid Ring Control (HRC), commonly known as FDDI-II, extends the capability of FDDI to handle isochronous data streams at a multiplicity of data rates. Another extension, ISO/IEC9314-4, provides for a single-mode optical fibre version of PMD (SM
39、F-PMD) and will permit optical links of up60km. Other extensions, addressing alternate PMDs, will provide low-cost attachments for use in concentrator-to-workstation environments. This part of ISO/IEC9314 for SMT represents the final standard in the set of basic FDDI standards. SMT is a sophisticate
40、d document specifying many critical aspects of interoperability in a multi-vendor FDDI network and, as such, has proved to be by far the most difficult of the set of FDDI standards to complete. The successful completion of the work on SMT is the result of a high degree of cooperation between competi
41、ng manufacturers of FDDI equipment. 1 Scope This part of ISO/IEC9314 specifies the Station Management (SMT) for the Fibre Distributed Data Interface (FDDI). FDDI provides a high bandwidth (100megabits per second) general purpose interconnection among computers and peripheral equipment using optical
42、fibre as the transmission medium in a ring configuration. FDDI can be configured to support a sustained transfer rate of approximately80megabits(10megabytes) per second. The use of dual attachment stations with dual MACs allows these rates to be doubled under the circumstance of a fault-free FDDI ri
43、ng. FDDI establishes the connection among many stations (nodes) distributed over distances of several kilometres in extent. Default values for FDDI were calculated on the basis of1000 physical connections and a total fibre path length of200km. The FDDI consists of a) A Physical Layer (PL), which pro
44、vides the medium, connectors, optical bypassing, and driver/receiver requirements. PL also defines encode/decode and clock requirements as required for framing the data for transmission on the medium or to the higher layers of the FDDI. For the purposes of this part of ISO/IEC9314, references to the
45、 PL are made in terms of the Physical Layer protocol (PHY) and the Physical Layer Media Dependent (PMD) entities which are the upper and lower sublayers of PL, respectively. b) A Data Link Layer (DLL) which controls the accessing of the medium and the generation and verification of frame check seque
46、nces to assure the proper delivery of valid data to the higher layers. DLL also concerns itself with the generation and recognition of device addresses and the peer-to-peer associations within the FDDI network. For the purposes of this part of ISO/IEC9314, references to the DLL are made in terms of
47、the Media Access Control (MAC) entity which is the lowest sublayer of DLL.BSISO/IEC9314-6:1998 2 BSI 08-1999 c) A Station Management (SMT) standard, this part of ISO/IEC9314, which provides the control necessary at the station (node) level to manage the processes underway in the various FDDI layers
48、such that a station may work cooperatively as a part of an FDDI network. SMT shall provide services such as connection management, station insertion and removal, station initialization, configuration management, fault isolation and recovery, communications protocol for external authority, scheduling
49、 policies, and collection of statistics. The definition of SMT as contained herein includes the set of services that it provides for, and receives from, the other entities that are contained within a node. Within SMT resides both knowledge of the uniqueness of this node and the current network structure to the extent that this nodes function is affected. The set of International Standards for FDDI, ISO/IEC9314, specifies the interfaces, functions and operations necessary to insure interoperabili
