White Rabbit is the name of a collaborative project including CERN, GSI Helmholtz Centre for Heavy Ion Research, and other partners from universities and industry develop together a fully deterministic Ethernet-based network for general purpose data transfer and sub-nanosecond accuracy synchronization. Its initial use was as a timing distribution network for control and data acquisition timing of the accelerator sites at CERN as well as in GSI's FAIR project. The hardware designs as well as the source code are publicly available at the "White Rabbit Overview". 〔The name of the project is a reference to the White Rabbit appearing first in Lewis Carroll's novel Alice's Adventures in Wonderland. == Focus and goals == White Rabbit provides sub-nanosecond synchronization accuracy, which formerly required dedicated hard wired timing systems, with the flexibility and modularity of real-time Ethernet networks. A White Rabbit network may be used solely to provide timing and synchronization to a distributed electronic system, or be used to provide both timing and real-time data transfer.〔〔 The White Rabbit Project focuses on: * Sub-nanosecond accuracy: synchronization of more than 1000 nodes via fiber or copper connections of up to 10 km of length. * Flexibility: creates a scalable and modular platform with simple configuration and low maintenance requirements. * Predictability and Reliability: allows the deterministic delivery of highest priority messages by using Class of service. * Robustness: no losses of high priority system device control messages. * Open source hardware and software: to avoid vendor lock-in. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「The White Rabbit Project」の詳細全文を読む スポンサード リンク
