摘要:
A method is provided in one example embodiment and includes generating a first document and a second document associated with video data that includes a group of pictures (GOPs). The method also includes hashing a plurality of video frames associated with the video data. Additionally, the method includes appending each of the video frames' respective hash and respective display times to the first document, and appending each of a plurality of I-frames' respective hash and respective display times to the second document. The method further includes communicating the first document and the second document in a reliable manner over a network to a next destination.

A network content service apparatus includes a set of compute elements adapted to perform a set of network services; and a switching fabric coupling compute elements in said set of compute elements. The set of network services includes firewall protection, Network Address Translation, Internet Protocol forwarding, bandwidth management, Secure Sockets Layer operations, Web caching, Web switching, and virtual private networking. Code operable on the compute elements enables the network services, and the compute elements are provided on blades which further include at least one input/output port.

In one embodiment a method and apparatus that support virtual services including virtual network interface control functionality for virtual machines running on a server. A method includes receiving a packet at a network interface card from a data communication network, classifying, within the network interface card, the packet to select one of multiple flow tables to which the packet should be assigned to obtain a selected flow table, the classifying being based, at least, on a logical interface with which the packet is associated, processing the packet based on information stored in the selected flow table, and passing the packet to a virtual machine operating on a computer to which the network interface card is communicatively connected, the virtual machine being associated with the logical interface.

A method for enabling secure communication between a client on an open network and a server apparatus on a secure network. The method is generally performed on a intermediary apparatus coupled to the secure network and the open network. The method includes the steps of negotiating a secure communications session with the client apparatus via the open network; negotiating an open communications session with the server via the secure network; receiving encrypted packet application data having a length greater than a packet length via multiple data packets; decrypting the encrypted packet application data in each data packet; forwarding decrypted, unauthenticated application data to the server via the secure network; and authenticating the decrypted packet data on receipt of a final packet of the segment.
摘要:
A system and method for transmitting information between a source host and a destination host. A source host generates a message and forwards the message via a label switched path to the destination host so that when a central routing module receives the message, the message includes a label. A central routing module establishes a local master mapping table including a plurality of physical addresses, and each of the plurality of physical addresses is associated with a unique identifier such as a label. When a switch egress module receives the message with the label, the switch egress module determines a physical address associated with the label, maps the physical address to the message, and forwards the message to the destination host associated with the label.

In one embodiment, a method includes receiving a request packet at a flow director in communication with a plurality of servers, each server comprising a virtual load balancer module and one or more virtual machines and forwarding the request packet to one of the virtual load balancer modules at one of the servers. The virtual load balancer module is configured to select one of the virtual machines to receive the request packet and transmit a response packet. The response packet is transmitted without passing through the flow director. An apparatus for load balancing in a virtual machine environment is also disclosed.

An acceleration apparatus is adapted to operate in a direct mode and a proxy mode. In the direct mode, the acceleration apparatus decrypts data packets received from a client and forwards the decrypted data packets to a server using a communication session negotiated by the client and the server. In the proxy mode, the acceleration apparatus responds to the client on behalf of the server and forwards the decrypted data packets to the server using a communication session negotiated by the acceleration device and the server. The acceleration apparatus automatically switches from the direct mode to the proxy mode upon detection of a communication error associated with the communication session negotiated by the client and the server.
