InfiniBand uses a switched fabric topology, as opposed to early shared medium Ethernet. All transmissions begin or end at a channel adapter. Each processor contains a host channel adapter (HCA) and each peripheral has a target channel adapter (TCA). These adapters can also exchange information for security or quality of service (QoS).
It was introduced by IBM in 1984, and standardized in 1989 as IEEE 802.5. It uses a special three-byte frame called a token that is passed around a logical ring of workstations or servers . This token passing is a channel access method providing fair access for all stations, and eliminating the collisions of contention -based access methods.

FDDI provides a 100 Mbit/s optical standard for data transmission in local area network that can extend in length up to 200 kilometers (120 mi). [2] Although FDDI logical topology is a ring-based token network, it did not use the IEEE 802.5 Token Ring protocol as its basis; instead, its protocol was derived from the IEEE 802.4 token bus timed token protocol.
Mellanox Technologies announced the first 100 Gbit/s network adapter with PCIe 4.0 on 15 June 2016, [75] and the first 200 Gbit/s network adapter with PCIe 4.0 on 10 November 2016. [76] In August 2016, Synopsys presented a test setup with FPGA clocking a lane to PCIe 4.0 speeds at the Intel Developer Forum. Their IP has been licensed to several ...
UHBR 13.5: 4 × 13.5 Gbit/s = 54.00 Gbit/s bandwidth (data rate of 52.22 Gbit/s or 6.52 GB/s) UHBR 20 : 4 × 20.0 Gbit/s = 80.00 Gbit/s bandwidth (data rate of 77.37 Gbit/s or 9.69 GB/s) The transmission mode used by the DisplayPort main link is negotiated by the source and sink device when a connection is made, through a process called Link ...
USB4 has, from the start, referenced the PCI Express Specification Revision 4 and with USB4 Version 2.0 added references to PCI Express Specification Revision 5.0. PCIe tunneling has had a significant limitation in USB4 Version 1.0 and also Thunderbolt 3: PCIe Express has a variable maximum payload size , which applies end-to-end to a transmission.
