Abstract: An apparatus and method are described for discovering a configured tunnel between nodes on a path in a data communications network. In an embodiment, an apparatus is arranged to remotely access at least one node on the path, identify whether a tunnel is configured on the access node and, if so, identify whether the identified tunnel has a fault.

Abstract: An apparatus and method for determining availability of a network service having a plurality of end points are described. The apparatus and method are arranged to receive a service notification from the service end point notifying availability of a service at the service end point and indicating other service end points for said service, and to identify said service as available if all service end points for said service have notified availability for said service.

Abstract: In one embodiment, an exploratory linktrace is initiated from an initiating network device with an exploratory linktrace message (ELM) having a target address. Each network device receiving the ELM may then propagate the ELM on a plurality of its ports to a plurality of downstream network devices based on the target address. In addition, each receiving network device returns an exploratory linktrace reply (ELR) for each of the plurality of ports, where each ELR is returned according to one or more mechanisms to mitigate stormed replies to the initiating network device.

Abstract translation: 在一个实施例中，从具有目标地址的探索链路跟踪消息（ELM）的发起网络设备发起探索性链路跟踪。 接收ELM的每个网络设备然后可以基于目标地址将多个其端口上的ELM传播到多个下游网络设备。 另外，每个接收网络设备返回针对多个端口中的每一个的探索性链路跟踪应答（ELR），其中根据一种或多种机制返回每个ELR，以减轻对发起网络设备的暴风骤雨的回复。

Abstract: In one embodiment, an illustrative technique determines when an end-user is within a specified proximity of a client device configured to provide an interface to a virtual machine. In response to the end-user being within the specified proximity of the client device, the technique may then allocate data center resources for the virtual machine.

Abstract translation: 在一个实施例中，说明性技术确定最终用户何时位于被配置为向虚拟机提供接口的客户端设备的指定接近度内。 响应于最终用户在客户端设备的指定接近度内，该技术可以为虚拟机分配数据中心资源。

Abstract: The specification provides information for determining any impacted customers, virtual private networks, circuits, and devices following a path failure. The specification uses an information-gathering component to find system information and uses the system information in determining any impacted units. A report is created that allows a network management system to process the impacted units. If any of the impacted units are customer devices, then the management system calculates the impact on the customer based on a Service Level Agreement.
