摘要： PROBLEM TO BE SOLVED: To provide policy-based quality of service (QoS) within a network by adopting a non-deterministic access protocol which not only has a functionality for prioritizing and servicing different traffic classes but also accomplishes additional management of bandwidth and gives a scale with which a service to a packet relating to a specific traffic class can be measured. SOLUTION: A packet forwarding device receives information indicative of a set of traffic groups. The packet forwarding device additionally receives parameters, such as bandwidth and priority order parameters corresponding to the traffic groups. After receiving a packet associated with one of the traffic groups on a first port, the packet forwarding device schedules the packet for transmission from a second port based upon parameters corresponding to the traffic group with which the packet is associated. Advantageously, this method can achieve a weighted equal queueing transport schedule sharing bandwidth based on a series of rules. COPYRIGHT: (C)2007,JPO&INPIT

摘要： A flexible, policy-based, mechanism for managing, monitoring, and prioritizing traffic within a network and allocating bandwidth to achieve true quality of service (QoS) is provided. According to one aspect of the present invention, a method is provided for managing bandwidth allocation in a network that employs a non-deterministic access protocol, such as an Ethernet network. A packet forwarding device receives information indicative of a set of traffic groups, such as: a MAC address, or IEEE 802.1p priority indicator or 802.1Q frame tag, if the QoS policy is based upon individual station applications; or a physical port if the QoS policy is based purely upon topology. The packet forwarding device additionally receives bandwidth parameters corresponding to the traffic groups. After receiving a packet associated with one of the traffic groups on a first port, the packet forwarding device schedules the packet for transmission from a second port based upon bandwidth parameters corresponding to the traffic group with which the packet is associated. According to another aspect of the present invention, a method is provided for managing bandwidth allocation in a packet forwarding device. The packet forwarding device receives information indicative of a set of traffic groups. The packet forwarding device additionally receives information defining a QoS policy for the traffic groups. After a packet is received by the packet forwarding device, a traffic group with which the packet is associated is identified. Subsequently, rather than relying on an end-to-end signaling protocol for scheduling, the packet is scheduled for transmission based upon the QoS policy for the identified traffic group.

摘要： A flexible, policy-based, mechanism for managing, monitoring and prioritizing traffic within a network and allocating bandwidth to achieve true quality of service (QoS) is provided. A method is provided for managing bandwith allocation in a network. A packet forwarding device (100) receives information indicative of a set of traffic groups, such as MAC address, or IEEE 802.1p priority indicator or a 802.1Q frame tag, if the QoS policy is based upon individual station applications; or a physical port if the QoS policy is based purely upon topology. The packet forwarding device additionally receives information defining a QoS policy (210) for the traffic groups. After a packet is received (220), a traffic group id identified (230). The packet is scheduled (260) for transmission based upon the QoS policy for the identified traffic group rather than relying on an end-to-end signalling protocol.
摘要翻译：提供了一种灵活的，基于策略的机制，用于管理，监控和优先化网络中的流量，并分配带宽以实现真正的服务质量（QoS）。根据本发明的一个方面，提供一种用于管理采用诸如以太网之类的非确定性接入协议的网络中的带宽分配的方法。如果QoS策略基于各个站应用，则分组转发设备接收指示一组业务组的信息，诸如：MAC地址或IEEE 802.1p优先级指示符或802.1Q帧标签; 或物理端口，如果QoS策略完全基于拓扑。分组转发设备另外接收对应于业务组的带宽参数。在接收到与第一端口上的一个流量组相关联的分组之后，分组转发设备基于与分组所关联的业务组对应的带宽参数，从第二端口调度分组进行传输。根据本发明的另一方面，提供了一种用于管理分组转发设备中的带宽分配的方法。分组转发设备接收指示一组业务组的信息。分组转发设备另外接收定义业务组的QoS策略的信息。在分组转发设备接收到分组之后，识别与该分组相关联的业务组。随后，不是依靠端到端的信令协议进行调度，而是基于所识别的业务组的QoS策略来调度分组进行传输。
