White Rabbit provides sub-nanosecond accuracy and picoseconds precision of synchronization for large distributed systems. It also allows for deterministic and reliable data delivery.
White Rabbit allows you to precision time-tag measured data and lets you trigger data taking in large installations while at the same time using the same network to transmit data.
connecting thousands of nodes
typical distances of 10 km between nodes
Ethernet-based gigabit rate reliable data transfer
fully open hardware, firmware and software
multi-vendor commercially produced hardware
Computer history collections: PDP-10 archive (includes the TECO Emacs), SIMH the computer history simulator and a copy of bitsavers, which contains lots of software and high-resolution scans of many documents (including e.g. data books of electronic parts).
With this posting of the Bell System Technical Journal from volume 1 issue 1 in July 1922 to the final issue published in December 1983, we are pleased to be able to open the vault of this knowledge to our global technical colleagues.
Alcatel-Lucent is now proud to partner with IEEE to provide access to the Bell Labs Technical Journal (1996-present) and all of its predecessors: the Bell Labs System Technical Journal (1922-1983), AT&T Bell Labs Technical Journal (1984), and AT&T Technical Journal (1985-1996).
