    摘要： Aspects of the invention provide a method and system for managing or coordinating data transmission in a Local Area Network (LAN) such that Quality of Service (QoS) concerns are met. A LAN resource manager (LRM) is provided for managing the LAN resources by providing solutions for providing users with several levels of QoS. Once the LRM admits a user at a certain QoS level, the level is assured within the LAN for as long as the user is in the LAN. A user may submit a request to transmit data to the LRM. The LRM may determine if time allocation is possible and allocate the time slots for data transmission. The LRM may send time slot allocation information to an Access Server in a LAN, which may inform the user of the time slot allocation and prepare a queue according to the slot allocation information.

    摘要： A method of controlling a communication network including VC exchange nodes and VP exchange nodes such that the cell flow of each VP can be maintained within the prescribed characteristic while the end-to-end cell transfer quality for VCs can be estimated easily and accurately. In the network, a cell transfer from the VC exchange nodes to the VP exchange nodes is controlled within prescribed traffic characteristics specified to VPs; a cell transfer quality at each of the VC exchange node is specified in terms of a first cell transfer quality dependent on the control of the cell transfer, and a second cell transfer quality independent on the control of the cell transfer: a cell transfer quality at each of the VP exchange node is specified by a third cell transfer quality independent on the control of the cell transfer alone; an end-to-end cell transfer quality for each VC in the network is estimated in terms of the cell transfer quality of each of the VC exchange nodes and the cell transfer quality of each of the VP exchange nodes: and the bandwidth management in the network is carried out such that the estimated end-to-end cell transfer quality becomes higher than a desired quality of service.

    摘要： A packet network in which the qualities of service can be maintained for different communications of different classes of requirement for quality of service, regardless of types of calls and data. In this packet network, a communication resource is subdivided into sub-resources which are to be allocated to communications classified into communication classes, where an amount of communications within each sub-resource is controlled independently to satisfy a required quality of service. Also, first type of calls for which a ratio of a maxium transfer speed of each call with respect to a transfer speed of multiplexed line of the packet network is greater than a predetermined threshold value, and second type of calls which are not the first type of calls are distinguished, and a priority control to favor the first type of calls over the second type of calls is performed.
