High Speed Token Ring, or HSTR, is a new token ring standard that
promises to push token ring speeds to 100 Mbps and 1 Gbps. The High
Speed Token Ring Alliance consists of 3Com, Bay Networks, IBM,
Madge, Olicom, UNH Interoperability Lab, and Xylan.
The first HSTR specification will allow for 100 Mbps token ring
speeds over both Type 1 and UTP copper cabling. Further
specifications will tackle 100 Mbps token ring over fiber. These
standards are due for completion in June or July of 1998. Another
HSTR specification will allow for 1 Gbps HSTR over fiber, and this
standard is due to be completed at the end of 1998.
