    • A policy-driven automatic network remediation service is described, which resides on the network and is triggered when a network fault is detected. Once triggered, the service automatically connects to network devices in the topological locale of the detected fault and collects diagnostic information from the affected area, running diagnostics which are appropriate to the fault type. The service can validate a set of preconditions prior to taking remedial action. For example, the service can empirically validate that the network topology is actually as expected and that automatic remediation would be safe and would not compromise network availability or redundancy. Diagnostic information can be recorded in a trouble ticket to support post-event auditing. Once the preconditions have been validated, the service can automatically take corrective action based on the type of the fault, such as shutting down an interface on a particular network device.
    • 描述了一种策略驱动的自动网络修复服务,它驻留在网络上,并在检测到网络故障时触发。 一旦触发,服务将自动连接到检测到的故障的拓扑区域中的网络设备,并从受影响的区域收集诊断信息,运行适用于故障类型的诊断。 该服务可以在采取补救措施之前验证一组先决条件。 例如,该服务可以经验地验证网络拓扑实际上是如预期的那样,并且自动修复将是安全的,并且不会损害网络可用性或冗余。 诊断信息可以记录在故障单中以支持事件后审核。 一旦先决条件得到验证,服务就可以根据故障的类型自动采取纠正措施,例如关闭特定网络设备上的接口。

    • A vibratory roller is provided with an exciter assembly that need not be lubricated by an oil bath because the exciter gears need not be lubricated. At least an outer ring portion of at least one gear of the exciter assembly is formed from a non-metallic material. In one embodiment, a first gear is a composite gear having an outer toothed ring portion formed from a machined nylon material imbedded with at least one of a heat stabilizer and a lubricant, and a second, mating gear is formed from metal and acts as heat sink for the first gear. In another embodiment, both the first and second gears are composite gears having an outer toothed ring formed from a robust and thermally stable molded polymer. The gears can survive when the roller is operated at least 8 hours at a duty cycle of at least 50% while operating the roller at an ambient temperature of over 38° C. (100° F.) and while the exciter shaft is driven at a velocity of over 2,000 RPM and the exciter housing is subjected to over 31.13 kN (7,000 lbf) of centrifugal forces at a vibrational frequency of over 40 Hz.
