    Abstract: Methods, apparatus and program products for controlling a flow of a plurality of packets in a computer network are disclosed. The computer network includes a device defining a queue. The methods, apparatus and program products include determining a queue level for the queue and determining an offered rate of the plurality of packets to the queue. They also include controlling a transmission fraction of the plurality of packets to or from the queue, based on the queue level, the offered rate and a previous value of the transmission fraction so that the transmission fraction and the queue level are critically damped if the queue level is between at least a first queue level and a second queue level. Several embodiments are disclosed in which various techniques are used to determine the manner of the control.

    Abstract: A system and method of moving information units from a network processor toward a data transmission network in a prioritized sequence which accommodates several different levels of service. The present invention includes a method and system for scheduling the egress of processed information units (or frames) from a network processing unit according to stored priorities associated with the various sources of the information units. The priorities in the preferred embodiment include a low latency service, a minimum bandwidth, a weighted fair queueing and a system for preventing a user from continuing to exceed his service levels over an extended period. The present invention includes a plurality of calendars with different service rates to allow a user to select the service rate which he desires. If a customer has chosen a high bandwidth for service, the customer will be included in a calendar which is serviced more often than if the customer has chosen a lower bandwidth.

    Abstract: PROBLEM TO BE SOLVED: To provide a bandwidth maintenance queue manager for (first-in first-out)FIFO buffer provided with another DRAM storage device for maintaining a FIFO queue. SOLUTION: A FIFO buffer is used on an ASIC chip so that plural queue entries can be stored and retrieved. As long as the total size of queues does not exceed a usable storage device in the buffer, any data storage device is not required more. When supplied data exceeds the buffer storage space of a certain prescribed quantity in the FIFO buffer, however, these data are written in the other data storage device in the form of packet and read from that storage device. That packet has an optimal size for maintaining the peak performance of the data storage device and is written in the data storage device in a way such as queuing with the address sequence of FIFO.
