Abstract: A method and system for reassignment of packet-pipes at a telecommunications switch. Upon detection of an increase in capacity of a packet-pipe (originating from a cell-site, for instance) and determination that the increase would overload a handler-module at the switch, a processor may analytically identify one or more packet-pipe reassignments that should be made at the switch so as to accommodate the increase in capacity. The processor may do so by successively considering the viability and impact of various possible reassignments. And the processor may produce an output report that indicates the reassignment(s) to make in order to accommodate the increase in capacity.

Abstract: A searching method for optimizing the rate of penetration of a drill into a given medium based upon the two drilling parameters of thrust and speed of revolution. Preset base values of both parameters are input into the drilling control mechanism at the start of the process. Thereafter, based upon readings from an automatic penetration rate calculator, incremental changes are automatically made to one of the parameters, the other being held constant, until a maximized rate of penetration is established. Subsequently, the other parameter, previously held constant, is changed until a new maximized penetration rate is found. This optimized penetration rate searching is continuously and automatically effected until the drilling process is completed. The method additionally provides for the allowance of a wait period between successive incremental changes for accommodating response times of the system as well as instabilities which may occur as the result of nonlinear process dynamics.
