Token passing data transfer mechanism for reservation based protocols

摘要

Token passing data transfer mechanism for reservation based protocols is provided. In some embodiments, a token passing data transfer mechanism for reservation based protocols includes sharing a reservation between a first device and a second device including transmitting a zone activity frame from the first device to the second device to modify the default allocation of the reservation blocks between the first device and the second device, in which the zone activity frame includes a first bit mask indicating which zone reservation blocks the first device requests for transmitting data to the second device during a plurality of zones of the superframe, in which a zone reservation block includes a plurality of contiguous reserved slots within a zone, and the second reservation includes a plurality of zones.
