摘要： According to one embodiment, a method includes performing functionality of a management plane and a control plane for a switch system using a processor of an external host coupled to the switch system via one or more peripheral component interconnect express (PCIe) ports. The method also includes providing a direct memory access (DMA) facility between the external host and switching logic of the switch system. The switch system includes a PCIe interface block coupled to PCIe ports configured to couple to external PCIe devices. Also, the PCIe interface block includes logic configured to provide DMA for each PCIe lane thereof. The switch system also includes multiple switched Ethernet ports configured to couple to one or more external Ethernet devices and switching logic configured to switch between the multiple switched Ethernet ports and the PCIe ports using DMA and a local processor coupled to the PCIe interface block.

摘要： Embodiments of the invention relate to providing quantized congestion notification (QCN) in networks. One embodiment includes a method that includes determining a traffic flow congestion by a particular congestion point (CP) unit of multiple CP units that communicate with at least one end unit, at least one reaction point (RP) unit and at least one controller in a network. A first congestion notification message (CNM) and a second CNM are generated by the particular CP unit. The particular CP unit sends the first CNM directly to the controller and the second CNM directly to the RP unit. Traffic flow is managed among the multiple CP units by the controller based on the first CNM.

摘要： A method includes determining, by a congestion point (CP) unit, traffic flow congestion in an Open Flow environment network. The CP unit comprises an Open Flow switch including a device including logic where an action is associated with each flow entry in the device. A congestion point (CP) unit sends a first congestion notification message (CNM) directly to at least one controller and sends a second CNM directly to at least one reaction point (RP) unit. The CP unit communicates with the at least one controller through a secure channel via Open Flow protocol.
