TLDR
In this paper, a credit manager circuit determines whether a stored packet complies with predetermined traffic parameters such as average arrival rate and maximum burst rate, based on a packet's arrival time and its virtual channel identifier (VCI).Abstract:Â
A method and system are provided for controlling user traffic to a fast packet switching system using the leaky bucket scheme. Each of the packets (53 byte length cell) originates at a source of packets and has a virtual channel identifier (VCI). The method includes the step of receiving the packets, each of the packets having associated therewith an arrival time. The packets are stored at an addressable location in a first memory. The first memory having a plurality of addressable locations. In a second memory, there are stored addresses corresponding to the addressable locations in the first memory in which a packet is not yet stored. The addresses stored in the second memory are utilized in the step of storing the received packets. A credit manager circuit determines whether a stored packet complies with predetermined traffic parameters such as average arrival rate and maximum burst rate. This determination is based on a packet's arrival time and its VCI to obtain a validated packet. The credit manager circuit retrieves the validated packet from the first memory and the retrieved packet is then transmitted to the packet switching system.read more

Traffic scheduling system and method for packet-switched networks
Anujan Varma,Dimitrios Stiliadis +1 more
TL;DR: In this article, a traffic scheduling system and method for packet-switched communications networks where multiple sessions share an outgoing communications link is presented, in which packets are assigned a time-stamp and placed into a priority queue in order of ascending timestamps so that the packet with the smallest timestamp is placed at the head of the queue.

Bandwidth management and congestion control scheme for multicast ATM networks
TL;DR: In this article, a buffer reservation and congestion control scheme for multi-cast ATM networks is proposed, which includes buffer reservation mechanism comprised of a state machine for association with each virtual circuit set up through the network, the state machine being adapted to monitor the number of available buffer slots at a data link and reading an encoding scheme for cells comprising a burst of data in order to control its switching from an active to an idle state to control the flow of data through the virtual circuit.
