Abstract: Systeme und Verfahren werden für ein Aufsetzen eines virtuellen Netzwerks auf ein physisches Netzwerk in einer Rechenzentrumsumgebung bereitgestellt. Ein Überlagerungssystem ist in einem aufgesetzten virtuellen Netzwerk angeordnet und enthält einen Überlagerungs-Agent und ein Überlagerungs-Hilfeprogramm. Der Überlagerungs-Agent wird in einem Zugriffsschalter umgesetzt. Das Überlagerungs-Hilfeprogramm wird in einer Endstation umgesetzt, die mit dem Zugriffsschalter Daten austauschen kann. Überlagerungsparameter werden in Übereinstimmung mit einem Inband-Protokoll zwischen dem Überlagerungs-Agent und dem Überlagerungs-Hilfeprogramm übertragen.

Abstract: An approach is provided which a system selects a first virtual function from a plurality of virtual functions executing on a network adapter that includes a memory area. Next, the system allocates, in the memory area, a memory corresponding to the first virtual function. The system then stores one or more translation entries in the allocated memory partition, which are utilized to send data traversing through the first virtual function. As such, the system sends, utilizing one or more of the translation entries, the data packets from the network adapter to one or more destinations. In turn, the system dynamically resizes the memory partition based upon an amount of the memory partition that is utilized to store the one or more translation entries.

Abstract: A method for providing location independent dynamic port mirroring on distributed virtual switches is disclosed. A controller is provided to configure one or more virtual switches within a group of physical machines to appear as a set of distributed virtual switches. In response to the receipt of a data packet at a port of a physical machine, a determination is made whether or not the port has a monitor port located on the physical machine. If the port has a monitor port located on the same physical machine, a copy of the data packet is sent to the monitor port of the physical machine. If the port has a monitor port located on a different physical machine, a copy of the data packet along with an identification (ID) of the port and an ID of the monitor port are encapsulated, and the encapsulated information are sent to a controller.

Abstract: Systems and methods are provided for overlaying a virtual network on a physical network in a data center environment. An overlay system is arranged in an overlay virtual network to include an overlay agent and an overlay helper. The overlay agent is implemented in an access switch. The overlay helper is implemented in an end station that is in communication with the access switch. Overlay parameters in compliance with an in-band protocol are transmitted between the overlay agent and the overlay helper.
