Thunderbolt™ Technology
Thunderbolt technology is a new high speed optical data transfer technology developed by Intel Corporation to connect electronic devices to each other in a peripheral bus of a computer.
Intel started this project in 2009. In the initial Stages of this project, they named it as Light Peak.
In 2011 Intel marketed this technology with technical collaboration from Apple with a new name Thunderbolt.
In Feb 2011 Apple released their 4 products MacBook Air, MacBook Pro, iMac, and Mac mini with this technology.
What is Thunderbolt……?
Thunderbolt is a high-speed, Full duplex , Bi-directional optical cable technology designed to connect electronic devices to each other in a peripheral bus of a computer.
It is designed as a single universal replacement for current buses such as USB, SATA, SCSI, FireWire, PCI Express, HDMI, DVI and Display Port.
In comparison to these buses, Thunderbolt is much faster, longer ranged, smaller, and more flexible in terms of protocol support.
Protocol Architecture
Thunderbolt technology is based on a switched fabric architecture with full-duplex links.
Other Technologies use bus-based I/O architectures
Each Thunderbolt port on a computer is capable of providing the full bandwidth of the link in both directions with no sharing of band- width between ports or between upstream and downstream directions.
Protocol Mapping
A protocol adapter detect the external device and identify its protocol.
The identified protocol information is mapped into transport layer packets.
Transport layer packets from source to destination maybe routed over different Thunderbolt controllers.
At destination protocol adapter recreates the mapped protocol from transport layer packets.
