摘要:
Methods and apparatus are provided for creating a secure zone having multiple servers connected to a resource virtualization switch through I/O bus interfaces, such as PCI Express or PCI-AS. Servers connected to the resource virtualization switch using I/O bus interfaces share access to one or more virtualized cryptographic accelerators associated with the resource virtualization switch. Applications on a server or system images running on hypervisor inside server can use cryptographic accelerators associated with the resource virtualization switch as though the resources were included in the server itself. Connections between multiple servers and the resource virtualization switch are secure non-broadcast connections. Data provided to a resource virtualization switch can be cryptographically processed using one or more shared and virtualized cryptographic accelerators.

Methods and systems are provided for routing traffic through a virtual router-based network switch. According to one embodiment, a method for routing packets in a router includes establishing a flow data structure, which identifies a packet flow through a virtual router in the router. When a packet is received, a comparison is performed between a subset of at least one packet header associated with the packet and a subset of the flow data structure. If the subset of the packet header matches the subset of the flow data structure, then the packet can be hardware accelerated to a network interface. Otherwise, the packet may be either dropped or forwarded to a general purpose processor for processing.
摘要:
Methods and apparatus are provided for transferring data between servers and a remote entity having multiple peripherals. Multiple servers are connected to a remote entity over an Remote Direct Memory Access capable network. The remote entity includes peripherals such as network interface cards (NICs) and host bus adapters (HBAs). Server descriptor rings and descriptors are provided to allow efficient and effective communication between the servers and the remote entity.
摘要:
Methods and systems are provided for routing traffic through a virtual router-based network switch. According to one embodiment, a flow data structure is established that identifies current packet flows associated with multiple virtual routers in the virtual router-based network device. When an incoming packet is received by the virtual router-based network device, it is then determined whether the incoming packet is associated with a current packet flow by accessing the flow data structure based on a header associated with the incoming packet. If it is determined that the incoming packet is associated with the current packet flow, then the incoming packet is hardware forwarded via a network interface of the virtual router-based network device without intervention by a processor of the virtual router-based network device, otherwise the incoming packet is forwarded to software on the processor for flow learning.
摘要:
Methods and apparatus are provided for improving communication between processors in separate computer systems. Components and peripherals in individual computer systems communicate using input/output (I/O) buses such as PCI Express buses. The I/O buses are extended to allow interconnection between computer systems without having to introduce network infrastructure. A transfer controller supporting Direct Memory Access (DMA) is provided to allow even more efficient communication between computer systems.
