Abstract: A watch bezel provides a GMT function and a count-up time-tracking function. The watch bezel includes a first set of indicia to indicate 24 hours associated with the GMT function of the watch and a second set of indicia to indicate 60 minutes in an hour. When mounted or attached to the watch casing or body, the bezel is rotatable in the clockwise direction and in the counter-clockwise direction. The watch bezel enables a user to read or set the time associated with a secondary time zone without adjusting any hands on the watch. The second set of indicia comprises a plurality of incremental minute markers and allows a user to track elapsed time. The capability of tracking elapsed time allows the watch to be used in activities that require tracking of elapsed time such as diving or other sporting events.

Abstract: A virtual router spans a number of physical routing devices. A set of physical ports on one of the physical routing devices is logically represented as a trunk. A respective port priority value is associated with each of those ports, and a device priority value is associated with the physical routing device. If a port in the trunk is out-of-service, then the device priority value can be adjusted by the port priority value associated with the out-of-service port. A corrective action can be implemented if the device priority value fails to satisfy a condition. For example, the physical routing device may failover to another one of the physical routing devices spanned by the virtual router.

Abstract translation: 虚拟路由器跨越多个物理路由设备。 其中一个物理路由设备上的一组物理端口在逻辑上表示为中继。 相应的端口优先级值与这些端口中的每一个相关联，并且设备优先级值与物理路由设备相关联。 如果中继端口不工作，则可以通过与停止端口关联的端口优先级值来调整设备优先级。 如果设备优先级值不能满足条件，则可以执行纠正措施。 例如，物理路由设备可以故障切换到由虚拟路由器跨越的另一个物理路由设备。
