IEEE Std 802.5v-2001 Part 5: Token Ring access method and Physical Layer specifications Amendment 5: Gigabit Token Ring operation -Description
Abstract: This amendment specifies the changes required to 802.5, 1999 Edition (8802-5:1998 base standard), 802.5r and 802.5j, 1998 Edition (8802-5:1998/Amd. 1:1998), and 802.5t-1999, to support 1000 Mbit/s Dedicated Token Ring (DTR) operation. The base standard together with Amendment 1 specifies shared and dedicated (point-to-point) Token Ring operation at both 4 and 16 Mbit/s using either the TKP Access Protocol or the TXI Access Protocol. 802.5t-2000 extends Token Ring operation to 100 Mbit/s for the DTR C-Port and Station using the TXI Access Protocol. This standard extends Token Ring operation to 1000 Mbit/s for the DTR C-Port and Station using the TXI Access Protocol. Extensions to the Media Access Control have been made to accommodate the requirements for the 1000 Mbit/s media rate.
Keywords: Token Ring operation, TKP Access Protocol, TXI Access Protocol, DTR C-Port and Station
