    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 Asynchronous Transfer Mode (ATM). 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 ATM 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 virtual circuit connection (VCC), a single virtual path connection (VPC), or multiple VCC's. The method ensures QoS for data transmitted between the first and the second CE via the Ethernet protocol to the ATM protocol and vice versa.

    Abstract translation: 支持在使用以太网和异步传输模式（ATM）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。 该方法支持网络中的多个QoS服务，其中第一CE使用以太网协议连接到第一边缘设备（互通单元），第二CE使用ATM协议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使用单个虚拟电路连接（VCC），单个虚拟路径连接（VPC）或多个VCC连接到边缘设备。 该方法通过以太网协议向ATM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 method and system for rerouting data in a communication network ring. The ring includes a plurality of nodes and a plurality of links. Each node includes a first port and a second port. Each first port is connected to a neighboring second port through a link of the plurality of links. The topology of the communication network ring is discovered and a forwarding database table is populated with static entries according to the discovered topology. Upon receiving notice of a failed link, which includes a source address of a node adjacent to the failed link, the topology and the source address of the node adjacent to the failed link is used to reconfigure the forwarding database table. Data is forwarded using the reconfigured forwarding database table without flooding the ring.

    Abstract: A method and system for interworking between an Ethernet communication network and an ATM network, in which a first network interface is operable to communicate with the Ethernet communication network using an Ethernet communication protocol. A second network interface is operable to communicate with the ATM communication network using an ATM protocol. A processing unit is in communication with the first network interface and the second network interface, in which the processing unit encapsulates frames received from the Ethernet network into ATM frames, decapsulates frames received from the ATM network to recover Ethernet frames and maps parameters corresponding to the received one of the ATM and Ethernet frames into the other of the ATM and Ethernet frames, the mapped parameters including connection configuration control plane information and data plane parameters corresponding to individual frames.
