Abstract: Encapsulated packets may be generated for different packets transmitted between a source instance and destination instance in a computer system. The source instance and destination instance may be implemented by different physical hosts linked by multiple network paths. Congestion of the multiple network paths may be determined and path-balancing polices may be implemented in response to the determined congestion. Each encapsulation packet comprises contents of a corresponding packet, and one or more data values selected in accordance with a path-balancing policy. The data values added to one encapsulation packet may differ from those added to another. Different network paths to the destination may be selected for different encapsulation packets of a given transmission based at least in part on the added data values.

Abstract: A humidification assembly includes an enclosure, for example, arranged around a component of a datacenter. A base extends through a wall of the enclosure. Inside the enclosure, the base includes a well. Outside the enclosure, the base receives a container having a total volume that includes water and air. Water may flow from the container through a passage in the base to the well, for example, until equilibrium is reached and a predetermined water level in the well is thereby maintained. Water from the well thus provides a replenishing source of water to be evaporated for humidifying the air within the enclosure.
