摘要： The present invention provides a method, computer-readable medium and device for dynamically managing allocation of bandwidth in a packet network using a Dynamic Setting Scheme (DSS) for Class Based Queuing (CBQ). The method includes the steps of maintaining a minimized reserved portion of bandwidth to minimize delay jitter and maximizing a shared portion of bandwidth to maximize overall bandwidth utilization. Allocation of bandwidth may be based on a sharing tree hierarchical scheme that provides for temporary borrowing of bandwidth by real-time applications from bandwidth of non-real-time applications and blocks borrowing of bandwidth by non-real-time applications from bandwidth of real-time applications. DSS typically provides for using measurable parameters, such as queue length and number of borrowing attempts per a predetermined length of time/observation window, as control triggers for implementing adjustment of bandwidth allocation. In one embodiment, the steps include measuring a predetermined parameter at predetermined observation window times and dynamically adjusting allocated bandwidth for parent classes of real-time traffic by adjusting an average of the predetermined parameter to have a value within a predetermined stable region.

摘要： In a node that receives cells for many connections, a method discards entire packets when the node's buffer is full. The selected connection is one that includes at least one cell that corresponds to the beginning of a packet. In another embodiment, the connection is chosen by first making an initial selection, determining whether that selection can stand, and if not, by making an alternate selection. When an alternate selection is made, a credit factor associated with the initial selection is decremented, while the credit factor of the alternate selection is incremented. The initial selection can be carried out by considering the overall traffic load at the node, the individual traffic loads that comprise the overall traffic load of the node, and the QoS that is desired for the various connections that are active in the node.

摘要： In a node that receives cells for many connections, a method selects cells for discarding when the node's buffer is full. The connection from which a cell is discarded is chosen based on the individual traffic loads of all the connections, on the traffic load of the chosen connection, and on the desired Quality-of-Service for the various connections. An embodiment is presented where a fair ratio of loss is defined for each of the set of connections that are active in the node based on the aforementioned traffic and QoS considerations. When an incoming cell finds the buffer full, a connection is selected in accordance with the computed fair ratio of loss values. When the connection thus selected does not have a cell to be discarded, another connection is selected for discarding a cell. To maintain the desired “fairness”, a credit factor is maintained in association with each of the subqueues in the buffer, and when the initially selected subqueue is replaced with a substitute subqueue, the credit factor of the former is decremented, and the credit factor of the latter is incremented.

摘要： An arrangement where a policy manager automatically generates configuration file updates for the routers in the network, as necessary, sends those updates to the appropriate routers, and causes the routers to install the configuration file updates in real-time. The automatic generation of configuration file updates is carried out in response to information that is delivered to the policy manager from a traffic measurement and flow analysis system that replaces the prior art analyzer system. The information that is generated by the traffic measurement and flow analysis system is sensitive to thresholds that the policy manager installs in the traffic measurement and flow analysis system.

摘要： A telecommunications method and system for providing and monitoring multiple classes of service to users seeking dial-up access to a given resource. Incoming calls from two user groups, one group subscribing to a first service level and the other group subscribing to a second service level, are initially assigned to open circuits in a first shared dial hunt group. When all circuits are busy, only calls from users subscribing to the second service level are routed to open circuits in a second dedicated dial hunt group so that second level service subscribers will have fewer calls blocked than first level service subscribers. In an alternative implementation, calls from users subscribing to a first service level are routed only to open circuits in a first dial hunt group and calls from users subscribing to a second service level are routed initially to open circuits in a second dial hunt group. When all circuits in the second dial hunt group are busy, calls from second level service subscribers are routed to the first dial hunt group. Service levels are monitored by placing test calls and measuring the number of blocked calls. Hunt group capacities can then be adjusted accordingly.

摘要： The invention provides methods and systems for providing priority processing to critical data as the data is transmitted across a network. A plurality of Internet protocol (IP) packets, each of which contains data and priority information, are received at a first router. The data contained in the IP packets is then encapsulated into frame relay frames containing the priority information. The frame relay frames are transmitted from the first router to a frame relay network in a manner determined by the priority information included in the frame relay frames. The frame relay flames are then transmitted across a frame relay network to a second router in a manner determined by the priority information included in the frame relay frames.
