Abstract: A system for configuring with an overlay configuration, a datacenter network of networking devices comprising at least an underlay fabric, an edge, and a ToR switch interconnecting one or several hosts on a rack, communicably connected to each other with an underlay configuration. The system comprises an API providing a user with a set of primitives providing instantiation capability of respective generic networking resources, the primitives being configured to be invoked and assembled by the user so as to provide an abstracted view of the overlay configuration. The system further comprises a Workflow engine to compute the overlay configuration according to the abstracted view, and an Overlay configuration builder to push the overlay configuration to the ToR switch and the edge. The pushed overlay configuration configures a NVE in the datacenter network as one of the ToR switch, depending on the business use case of the datacenter associated with the identity of the user.

Abstract: A method is devised of deploying a network configuration in a datacenter. The network configuration includes one of more points of interconnection, a point of presence of the datacenter being one of the one or more points of interconnection. Each of the one or more points of interconnection in the network configuration is modeled through objects comprising, for each given point of interconnection, a node object representing the point of interconnection, an interface object hierarchically inferior to the node object and representing a connection to the point of interconnection, an evpnEdge object representing the transport to/from of the point of interconnection in the network, and a layer object hierarchically inferior to the evpnEdge object, and representing the characteristics of the protocol of transport to/from the point of interconnection. The network configuration is set up by a succession of commands on the objects and then pushed to the datacenter.

Abstract: A wall element having at least one cooling channel formed therein, the wall element presenting an inside surface and an outside surface, the channel comprising a hole and a diffusion portion, the hole opening out at one end in the inside surface, and at the other end in a diffusion portion where it forms an orifice, the diffusion portion flaring around said orifice and being defined by a bottom wall and a side margin. Said bottom wall presents a first plane portion into which the hole opens out, and a second plane portion situated in front of the first plane portion, said first and second plane portions being inclined in the thickness of the wall. The oriented angle of inclination of said first plane portion is less than the positive oriented angle of inclination of said second plane portion.

Abstract: A portable towel having a rectangular sheet and a relatively smaller head piece. The head piece has a two layer section, forming a pocket with an openmouth, extending from a one layer section attached to the top edge of the sheet and to the inside of the pocket. In its folded state, the rectangular sheet is folded up and rolled inside of the pocket along with the one layer section of the head piece. The pocket is therefore being closed at its openmouth and carried over with a belt like handling feature. With the sheet being in its unfolded state, the pocket may be filled with any type of clothing articles to form a pillow or the like attached to the sheet. Also, the towel has a few pouches that can be filled with weights such as sand to hold it in place on the ground.
