摘要： A data security device for providing a network transport connection via a transparent network proxy that employs different encryption security mediums along a communications session between two endpoints by emulating one of the endpoints at an intermediate node such that the communication session appears as an atomic, secure connection to the endpoints yet provides appropriate security over the end-to-end connection. A sender node sends a connection request to establish a secure communication session with an intended receiver node. A transparent proxy on an intermediate node receives the request and establishes the link employing an encryption mechanism. The transparent proxy establishes a second link with the intended receiver, and applies a second, less expensive encryption mechanism. The transparent proxy combines the two links to form the trusted, secure connection but incurring only the mitigated expense over the second link.

摘要： A system and method are disclosed for providing a network service. A first criteria specifying a first set of flows from a first service manager is received at a forwarding agent. The first criteria specifies an expiration time interval. The first criteria is stored on the forwarding agent. A second criteria is received that specifies a second set of flows from a second service manager at the forwarding agent. The second set of flows includes flows that are in the first set of flows and the second criteria is designated as a lower priority criteria. The second criteria is stored on the forwarding agent. The first criteria is deleted from the forwarding agent upon the expiration of the expiration time interval. A packet is received that belongs to a flow that is included in the first set and the second set. It is determined that the packet matches the second set ant the packet is forwarded to the second service manager.

摘要： A funnel in fan out network device includes a fast uplink port operating at a first data rate. A plurality of slow ports operate at a second data rate. The second data rate is slower than the first data rate. A processor is configured to direct a packet received on one of the slower ports directly to the fast uplink port without looking up the destination address of the packet.

摘要： A network appliance is configured to store and retrieve instructions for handling a packet corresponding to a connection. The network appliance includes a connection storing processor configured to hash an incoming flow identifier for incoming packets to obtain an incoming hash; to hash an outgoing flow identifier for outgoing packets to obtain an outgoing hash; to insert an incoming entry corresponding to the incoming hash in a bidirectional hash table; and to insert an outgoing entry corresponding to the outgoing hash in a bidirectional hash table. A connection finding processor is configured to hash a packet identifier to obtain a packet hash; and to determine a matching entry in the bidirectional hash table that corresponds to the packet hash. A memory is configured to store the bidirectional hash table.

摘要： A system and method are disclosed for controlling access to a server. Instructions are sent to a forwarding agent that instruct the forwarding agent to forward packets to a service manager from clients attempting to establish a client connection to the server. A client connection is established with the client. A server connection is established from the service manager to the server and data is transferred from the server connection to the client connection.
