Spoke–hub distribution paradigm

The spoke–hub distribution paradigm (also known as the hub-and-spoke system) is a form of transport topology optimization in which traffic planners organize routes as a series of "spokes" that connect outlying points to a central "hub".

Delta Air Lines pioneered the spoke–hub distribution model in 1955,[1] and the concept revolutionized the transportation logistics industry after Federal Express demonstrated its value in the early 1970s.

Another method is to use focus cities to implement point-to-point service for high-traffic routes and to bypass the hub entirely.

The 1951 Security Treaty Between the United States and Japan, the 1953 U.S.–South Korea Status of Forces Agreement and the 1954 Mutual Defense Treaty between the United States and the Republic of China (later replaced by the Taiwan Relations Act) are some examples of such bilateral security relationships.

The meeting was the first time the US hosted the forum and was part of a US attempt to get the countries to strengthen military ties between themselves.
