This standard specifies protocols, procedures, and managed objects for a Link-local Registration Protocol (LRP) to replicate a registration database from one end to the other of a point-to-point link and to replicate changes to parts of that database. A facility is provided to purge the replicated database if the source becomes unresponsive. Provision is made for a proxy system to operate LRP on behalf of a controlled system. LRP is optimized for databases on the order of 1 Mbyte.

For the purpose of compatible interconnection of data processing equipment via a local area network (LAN) using the token ring access method, this part of ISO/IEC 8802 a) Provides a general description of the token ring local area network (LAN) architecture (clause 2); b) Defines the frame format, including the delimiters, address fields, information field, and framecheck sequence (FCS). Defines the Medium Access Control (MAC) frames, timers, and error counters (clause 3); c) Defines the MAC… read more protocols including finite state machines and state tables (clause 4); d) Defines the system level Physical layer (PHY) signaling specifications that are specific to a ring station (clause 5); e) Defines the managed objects necessary to manage the service and protocol elements that are involved in the management of a token ring station (clause 6); f) Defines the PHY station attachment specification for 4 and 16 Mbit/s operation. This includes the transmitter, receiver, medium interface connector, and transmission channel for both shielded twisted pair (STP) and unshielded twisted pair (UTP) media (clause 7); g) Defines the concentrator, incorporating multiple trunk coupling units (TCUs), for the attachment of a group of stations to the ring (clause 8); h) Includes the protocol implementation conformance statement (PICS) proforma in compliance with the relevant requirements, and in accordance with the relevant guidance, given in ISO/IEC 9646-2 : 19941 (annex A); i) Includes channel design examples and formulas for calculating cabling and concentrator system configurations (annex B); j) Describes jitter components and provides an example of jitter buildup using a phase lock loop recovery circuit (annex C); k) Provides informative transmitter filter design example (annex D); l) Provides recommended guidelines for safety and operating environments (annex E); m) Illustrates the MAC finite state machines in a notation similar to that used in ISO/IEC 8802-5 : 1992 (annex F); n) Describes major improvements made after the first edition of the standard (annex G); o) Provides a sample algorithm for the parsing of MAC frames (annex H); p) Provides recommendations for the use of token ring access priorities to support multimedia traffic (annex I); q) Provides bit error rate (BER) criteria for lobe media testing (annex P). read less

This standard specifies the protocol and procedures used to ensure that the synchronization requirements are met for time-sensitive applications, such as audio and video, across bridged and virtual bridged local area networks consisting of local area network (LAN) media where the transmission delays are fixed and symmetrical; for example, IEEE 802.3TM full-duplex links. This includes the maintenance of synchronized time during normal operation and following addition, removal, or failure of… read more network components and network reconfiguration. It specifies the use of IEEE I588TM specifications where applicable in the context of IEEE Std 802.1DTM-2004 and IEEE Std 802.1QTM-2005. Synchronization to an externally provided timing signal (e.g., a recognized timing standard such as UTC or TAI) is not part of this standard but is not precluded. read less
