IEEE 802.5) 4 or 16Mbps (30,000 64 byte packets per second theoretical limit). Ring type of LAN, currently (1993) connecting 10 million computers.
(1) Network technology that controls media access by passing a token (special packet or frame) between media-attached machines. (2) A network with a ring topology that passes tokens from one attaching device (node) to another. (3) The IBM Token-Ring LAN connection allows the RS/6000 system unit to participate in a LAN adhering to the IEEE 802.5 Token-Passing Ring standard or the ECMA standard 89 for Token-Ring, baseband LANs.
Network protocol for PCs, developed by IBM.
