摘要： A method and system for protecting a service available on a broadcast domain. A sub-domain is established within the broadcast domain. The sub-domain includes a group of nodes used to provide a communication path to the service. A primary sub-domain maintenance association and a back-up sub-domain maintenance association are monitored. The primary and sub-domain maintenance associations are a set of primary and back-up paths, respectively, representing connectivity between nodes acting as edge nodes in the sub-domain. A fault is detected within the primary sub-domain maintenance association and a switch to the back-up sub-domain maintenance association occurs.

摘要： Described are a system and method for identifying private resources associated with a communications network. A structured address format is defined having a plurality of character positions. Each character position is associated generally with a property of a managed resource in the communications network. A structured private address, constructed according to the structured address format, is assigned to the managed resource. Each character position of the assigned structured address has a value that identifies a specific instance of the property of the managed resource associated with that character position. Operations Systems Support (OSS) gives a common name to the managed resource and maintains an association between the common name and the structured address. The structured address format can follow a four-byte dotted decimal notation similar to IPv4 addresses. For addresses following this format, the OSS can use standard domain name system services to translate between common names and structured addresses.

摘要： The present disclosure provides protection systems and methods that provide a mechanism to identify/determine when an interconnection node has been isolated (i.e. when there is no connectivity between a pair of interconnection nodes), from a data path perspective. If/when this condition exists, actions are triggered on the subtending sub-ring that essentially perform a protection switch (which causes the subtending sub-ring nodes to cleanse their forwarding tables), and, more importantly, that remove any channel blocks on the subtending sub-ring. Extensions to the ITU-T G.8032 state machine are also provided that include support for operator command interactions (e.g. DNR, force switch, manual switch, etc.). The protection systems and methods of the present disclosure enable the reliable application of ITU-T G.8032 and the like to more complex (i.e. meshed) deployment environments, among other significant advantages.

摘要： Maintenance entities may be defined between customer and provider flow points to allow performance management to take place on an Ethernet network. The maintenance entities may be defined for access link, intra-domain, and inter-domain, and may be defined on a link or service basis. The maintenance entities may be used to monitor performance within a network or across networks, and may be used to monitor various performance parameters, such as frame loss, frame delay, frame delay variation, availability, errored frame seconds, service status, frame throughput, the number of frames transmitted, received or dropped, the status of a loopback interface, the amount of time a service has been unavailable, and many other parameters. Several management mechanisms may be used, and the measurements may be collected using a solicited collection method, in which a response is required and collected, or an unsolicited collection method in which a response is not required.

摘要： Protection switching in an Ethernet packet-switched network includes establishing first and second virtual circuits. The first virtual circuit carries packet traffic associated with a different service instance from packet traffic carried by the second virtual circuit. Packet traffic of the first virtual circuit is transmitted from a source network element to a sink network element through a first Ethernet tunnel. Packet traffic of the second virtual circuit is transmitted from the same source network element to the same sink network element through a second Ethernet tunnel. The second Ethernet tunnel is a different path through the Ethernet packet-switched network from the first Ethernet tunnel. During a protection switch, the first virtual circuit is switched from the first Ethernet tunnel to the second Ethernet tunnel. After the switch, packet traffic of the first virtual circuit and packet traffic of the second virtual circuit are transmitted over the second Ethernet tunnel.

摘要： Ethernet OAM connectivity check may be used to detect connectivity failures across a given pair of network elements on an Ethernet network. Connectivity check frames are generated and sent to a specific unicast DA or to a multicast DA. Once a network element begins to receive connectivity check frames, it expects to continue to receive further periodic connectivity check frames from that network element. If the network element stops receiving periodic connectivity check frames, it detects that connectivity to the sending network element is broken. Once a fault is identified, the fault may be verified using a loopback function, which causes a network element receiving an Ethernet frame to transmit a corresponding frame back to the original network element. Loopback may be intrusive such that all received frames are looped back except OAM frames, or non-intrusive where only OAM frames are looped back.
摘要翻译：以太网OAM连接检查可用于检测以太网上给定的一对网络上的连接故障。生成连通性检查帧并将其发送到特定的单播DA或多播DA。一旦网络元件开始接收连接性检查帧，它将期望从该网络元件继续接收进一步的周期性连接性检查帧。如果网络元件停止接收周期性连接检查帧，则它检测到与发送网元的连接断开。一旦识别到故障，就可以使用环回功能验证故障，这使得接收以太网帧的网络单元将相应的帧传送回原始网络单元。环回可能是侵扰性的，使得除了OAM帧之外，所有接收到的帧都被环回，或者只有OAM帧被环回的非侵入帧。

摘要： Connectivity fault notification is provided by generating an alarm indication signal at a device that is logically adjacent to the fault, and forwarding the alarm indication signal upward through various levels to at least one client level entity. The alarm indication signal may be suppressed at any level for a service instance if service is restored at that level, or if a protection path prevents disruption of the service instance at that level, or auto-suppressed at an originating node based on number of times transmitted or elapsed time. The alarm indication signal may include a point of failure indicator such as the MAC address of the device that generates the alarm indication signal, or a failed resource identity such as an IEEE 802.1AB LLDP MAC Service Access Point (“MSAP”). Further, the alarm indication signal may be employed to trigger use of the protection path.
摘要翻译：通过在与故障逻辑上相邻的设备处产生报警指示信号，并将报警指示信号向上通过各种级别转发到至少一个客户端级实体来提供连接故障通知。如果服务在该级别被恢复，或者如果保护路径防止在该级别的服务实例的中断或者在始发节点处基于次数自动抑制，则可以在服务实例的任何级别上抑制警报指示信号传送或消逝时间。报警指示信号可以包括诸如生成报警指示信号的设备的MAC地址或诸如IEEE 802.1AB LLDP MAC服务接入点（“MSAP”）之类的故障资源标识的故障点指示器。此外，可以采用报警指示信号来触发保护路径的使用。
