	Cambridge Apostles - Wikipedia, the free encyclopedia
		The Cambridge Apostles, also known as the Cambridge Conversazione Society, is an elite intellectual secret society at Cambridge University, founded in 1820 by George Tomlinson, a Cambridge student who went on to become the Bishop of Gibraltar.
		The Apostles first became well-known outside Cambridge in the years before the First World War with the rise to eminence of the group of intellectuals known as the Bloomsbury Group.
		When he returned to Britain, he in turn recruited other Cambridge students, at the instruction of his KGB handlers, including Straight, though Blunt was not the person who recruited Burgess, Philby, and MacLean, according to writer Russell Aiuto.

		To avoid designating some one ring node as special (and thereby making ring operation depend on that node's continued good health) some algorithm is required whereby all active repeaters can quickly and simply agree upon the need for initialization and recovery, and not fall all over one another trying to accomplish it.
		ring network were compared by measuring the board area required to hold the implementation of the network control logic up to but not including speed-matching buffers.
		In a token-controlled ring, an error may destroy the token at the worst possible time, or when a station nearing a deadline finally receives the token the message it sends may be damaged by an error, and retransmission may be needed.

		In the ring, the virtual token works as follows: each station sets a timer to a value consisting of its station number times 2*T. When this timer finally expires, it is this station's turn to initialize the signal format.
		Therefore, failure to see a flag within one ring transit time (determined by the repeater delay time, the maximum number of repeaters, and the maximum length of wire connecting the repeaters--about 0.5 ms in the present design) is another certain indication that the ring requires reinitialization.
		If joining the ring is accomplished by closing a relay, the jamming time T should be set to the larger of the ring transit time and the relay bounce time, so as to insure that reinitialization is not attempted until there is a chance it will work.

		Ring design problems The three difficult ring engineering problems referred to above appear to have elegant and straightforward solutions, and one of the reasons for trying out ring technology in the field is to verify that these solutions work well in practice.
		Second, when successive ring links are placed in tandem the maximum geographical span is multiplied by half the number of stations-- perhaps a factor of 100.
		For example, in a 50- node ring, one must plan to wait for as many as 50 maximum length messages to be sent until the token arrives.

		In 1937, he was appointed to a junior faculty position at Cambridge in connection with the establishment of a computing laboratory.
		John Lennard-Jones, Plummer Professor of Theoretical Chemistry at Cambridge University, was appointed part-time Director of the Mathematical Laboratory for a period of five years from 1 October 1937, and Wilkes was appointed as University Demonstrator (a post approximately equivalent to Assistant Professor in the United States).
		The Cambridge Ring was an empty-slot ring, which it was believed to be easier to maintain.

		The seminal Ethernet paper by Metcalfe and Boggs was a couple of years off, and in Cambridge Wilkes and Wheeler were actively pursuing their own approach to LAN design in the form of the Cambridge Ring.
		In the interim, Cambridge made the details of the Ring design available to other UK universities, and by the early 1980s the system was widely deployed.

	Chambers Reviews - Modin
		Yuri Modin was the NKVD case officer for the members of the Cambridge Spy Ring for the last three years of its life (1948-1951) before two members were forced to seek asylum in the Soviet Union to escape a counterintelligence hunt spearheaded by the almost equally famous VENONA/BRIDE cryptanalysis case.
		He was soon tasked with being the sole translator of the massive load of documents from the Cambridge Ring and developed an extensive knowledge of its members.
		Modin was also the last case officer of the ring and has to describe the stress mounting on the members as Philby was able to monitor progress in the VENONA case as it was about to unveil MacLean.

		This special token frame is repeated from station to station until arriving at a station that needs to transmit data.

		There were three rings in operation, connected using bridges, with a total of 100 or so hosts.
		Indeed, to avoid the host device driver from having to perform multiplexed reassembly, a hardware autoselect system could be used so that a new transmitter received the busy response from the destination if the destination was mid-block from another source.

		Please note that apparent similarities with either IBM Token Ring or Cambridge Ring are superficial.
		Since we have accepted that the best we can ever manage to do is to reduce the probability of bad packets not being detected, if we wish to do this, we may as well concentrate the effort in improving the CRC as anywhere else in the structure of the program.
		This checks to see if the incoming packet is both from the preceding station in the ring, and nearly finished, in which case it blocks until the token has been received and transmission of the new packet has started.

		The Urban Ring is a 15-mile circular or "circumferential" transit Corridor, which would serve as a "wheel" connecting the "spokes" of Boston's downtown-centered transit system.
		Here, the Ring Corridor crosses two of the city's three "anchor project" areas and is near the third; the Ring would ease transit trips for city residents to nearby jobs and other destinations which can now involve three or more transfers and take two hours.
		In Cambridge, the Ring Corridor passes through East Cambridge, Kendall Square and the proposed new neighborhood of "North Point," and continues through to the Charles River near the BU bridge, substantially improving transit links between the city's residential neighborhoods and major employment centers.
