摘要： The problem of allocating bandwidth on the upstream channel (26) of an HFC cable network (10) for contention-based transmission of requests that are us ed to reserve upstream bandwidth (26) for transmission of user data is solved b y a method of allocation which dynamically adapts to the prevailing offered lo ad of reservation requests. In one embodiment this is done by determining an appropriate size for a contention interval in each upstream transmission fra me by attempting to balance the rates of flow of user data into and out of a virtual global data queue using a fluid approximation method that is based o n a solution to a balanced equation relating the demand and supply of slots fo r data transmission within each frame.

摘要： An apparatus and method for an adaptive initial ranging scheme. The scheme (Fig. 4) takes a first and second system performance measurement using a fir st (404) and a second (406) backoff window size. The scheme then determines a third (408) backoff window size based on the above measurements (408). The scheme (Fig. 5) first provides ranging opportunities and specifies a first backoff window size for collision resolution (504), counts a first number of success outcomes in a first sample of ranging opportunity slots, and determines a first probability of success outcomes (506). The scheme then provides additional ranging opportunities and specifies a second backoff window size for collision resolution (508), skips a number of ranging opportunity slots at least equal to the first backoff window size (510), counts a second number of success outcomes in a second sample of ranging opportunity slots, determines a second probability of success outcomes (512) , determines a ratio R having a numerator equal to the second probability of success outcomes minus the first probability of success outcomes and a denominator equal to the second backoff window size minus the first backoff window size (514), and selects a third backoff window size based on at least the ratio R (516, 518).
