    Abstract: Traffic engineering and bandwidth management of bundled links may, at times, require the selection of one of a plurality of component links in a bundled link to use in admitting a connection requiring admission. While performing the selection it may be determined that more than one of the component links has the resources required to admit the connection. An admission policy may then be selected from among a plurality of admission policies. Based on the selected admission policy, a particular component link may then be selected. Such bandwidth management, based on admission policies, may be seen to be well suited to balancing and component link recovery in traffic engineered, connection-oriented MPLS networks.

    Abstract: The two types of virtual local area networks (VLANs) may be defined: p-bits-Inferred-scheduling class VLAN (p-VLAN); and VLAN-ID-Only-Inferred-scheduling class VLANs (v-VLAN). As such, upon receipt of an Ethernet frame, the type of VLAN associated with the Ethernet frame may be determined. The type of VLAN provides the receiving node with an indication of a method of determining a scheduling class. A p-VLAN supports multiple scheduling classes. For a p-VLAN, the scheduling class and drop precedence for the received Ethernet frame may be determined based on a “service map” that describes the relationship between the p-bits and forwarding treatment. A v-VLAN supports a single scheduling class. As such, the scheduling class for a received Ethernet frame may be determined based on the VLAN-ID of the received Ethernet frame. The described VLAN QoS information may be configured or signaled across the network. Advantageously, the methods may be applied in connectionless, connection-oriented and path-oriented Ethernet networks.

    Abstract translation: 可以定义两种类型的虚拟局域网（VLAN）：p-bits-Inferred-scheduling class VLAN（p-VLAN）; 和VLAN-ID-Only-Inferred-scheduling类VLAN（v-VLAN）。 因此，在接收到以太网帧时，可以确定与以太网帧相关联的VLAN的类型。 VLAN的类型为接收节点提供了确定调度类的方法的指示。 p-VLAN支持多个调度类。 对于p-VLAN，可以基于描述p位和转发处理之间的关系的服务映射来确定所接收的以太网帧的调度类别和丢弃优先级。 v-VLAN支持单个调度类。 因此，可以基于接收的以太网帧的VLAN-ID来确定接收到的以太网帧的调度类。 所描述的VLAN QoS信息可以通过网络配置或发信号通知。 有利地，该方法可以应用于无连接，面向连接和面向路由的以太网。

    Abstract: A method of supporting multiple quality of service (QoS) levels for data being transmitted between two networking devices, such as customer equipment (CE), that use Ethernet and Frame Relay (FR). The method supports multiple QoS services in a network where a first CE is connected to a first edge device (interworking unit) using the Ethernet protocol and a second CE is connected to a second edge device using the FR protocol. The edge devices may be directly connected together or they may be connected through a network backbone using any generally accepted network protocol. The first CE may be connected to the first edge device using a single Ethernet port, multiple Ethernet ports, a single virtual local area network (VLAN), or multiple VLAN's. The second CE is connected to an edge device using a single data link connection (DLC), or multiple DLC's. The method ensures QoS for data transmitted between the first and the second CE via the Ethernet protocol to the FR protocol and vice versa.

    Abstract translation: 支持使用以太网和帧中继（FR）的两个网络设备（例如客户设备（CE））之间传输的数据的多个服务质量（QoS）级别的方法。 该方法支持使用以太网协议将第一CE连接到第一边缘设备（互通单元）的网络中的多个QoS服务，并且使用FR协议将第二CE连接到第二边缘设备。 边缘设备可以直接连接在一起，或者它们可以使用任何普遍接受的网络协议通过网络主干连接。 第一个CE可以使用单个以太网端口，多个以太网端口，单个虚拟局域网（VLAN）或多个VLAN连接到第一个边缘设备。 第二个CE使用单个数据链路连接（DLC）或多个DLC连接到边缘设备。 该方法通过以太网协议向FR协议确保在第一和第二CE之间传输的数据的QoS，反之亦然。

    Abstract: A service aware policer considers conformance to committed parameters before considering conformance to excess parameters. Such a flexible policer, which may be considered to be concerned with two rates and three colors, may find application in IP DiffServ, Metro Ethernet, etc. In particular, the policer, given a service associated with a given received packet, uses a profile specific to the associated service, where the profile provides values for the two rates. Subsequently, a token bucket rate algorithm allows the policer to transmit the given received packet for marking with one of the three colors. The policer may operate in a Color Blind mode in which the one of three colors (green, yellow, red) already associated with a packet is not considered or a Color Aware mode in which the color already associated with a packet is considered together with the size of the packet. Advantageously, the parameters may be defined in such a way that the efficiency of handling in-profile traffic is improved for predominant service scenarios over a wide range of traffic parameters.
