TL;DR: In this paper, the authors propose a method of allocating available bandwidth between stations configured in a write token controlled loop communications network, where each station on the loop adds to the field the amount of its currently reserved bandwidth.
Abstract: Disclosed in a method of allocating available bandwidth between stations configured in a write token controlled loop communications network. When a station desires to reserve additional bandwidth to itself, it captures the write token and transmits a bandwidth allocation token which includes a field indicating the originating station's amount of currently reserved bandwidth. Each station on the loop adds to the field the amount of its currently reserved bandwidth. When the allocation token arrives back at the originating station, the write token is regenerated and transmitted. If the total amount or currently reserved bandwidth indicated in the allocation token plus the desired additional bandwidth sought to be reserved is less than the allocatable bandwidth, then the reservation is granted. The additional bandwidth desired is then added to the total reserved by the originating station.

TL;DR: This satellite system provides integrated voice and digital data communication services for corporations via a geosynchronous satellite IBM was contracted to build the Satellite Communications Controller (SCC) for the earth stations The SCC provides signal conversion, traffic switching, data multiplexing and TDMA control for the system Each SCC also determines its satellite bandwidth requirement and transmits this requirement to a special SCC callad the reference SCC The reference computes bandwidth allocations for all SCCs using the received requirements and periodically transmits these allocations to all Sccs.

TL;DR: Experimental methodology and control are discussed as possible reasons for the failure of additive factors methodology to discover the pool of resources demanded when tracking bandwidth is increased.
Abstract: Additive factors methodology was applied to dual task data to discover the pool of resources demanded when tracking bandwidth is increased. Ten subjects tracked signals of both low and high bandwidth and performed a cognitive loading task that was constructed to demand either central processing or response execution resources. The hypothesis that bandwidth increases demand response execution resources was not supported. Experimental methodology and control are discussed as possible reasons for the failure.
