摘要： Method and apparatus for integration of network address translation and source address security, including, but not limited to, determining whether a gateway computer is integrated for network address translation and source address security, is described. A client computer requests a first address from the gateway computer and then requests a second address from the gateway computer. The latter request is done with a different client identifier that is nearly equivalent, except for one bit, to the client identifier used for the prior address request. If the gateway computer is integrated for network address translation and source address security, in response to the latter request a public address will be provided from the gateway computer to the client computer.

摘要： Method and apparatus for Internet Protocol Security (IPSec) and Network Address Translation (NAT) integration is described. A client obtains a public address from a gateway for IPSec communication. A mapping table is used to form associations between a local address for the client and a destination address for a peer, an Internet Security Association and Key Management Protocol (ISAKMP) Initiator Cookie and a Security Parameters Index associated with communication between the client and the peer. Incoming and outgoing routing may be done at the gateway using the mapping table.

摘要： A method for selecting a network interface card (NIC) to be used to send an outgoing data packet from a server computer system having a plurality of NICs coupled thereto. The outgoing data packet is addressed using an Internet Protocol (IP) address and a Transmission Control Protocol (TCP) port number. A load balancing scheme is executed in order to select a NIC from the plurality of NICs. In one embodiment, the load balancing scheme is a function of the IP address; in alternate embodiments, the load balancing scheme is a function of the IP address and either the destination or source TCP port number. The media access control (MAC) address that represents the selected NIC is inserted in the outgoing data packet. The data packet is then sent using the selected NIC.

摘要： A method and apparatus for reducing a contention window range of a client device located in a wireless network is described. In one embodiment, network conditions present in the wireless network are monitored. The network conditions are subsequently utilized to determine if the wireless network is small or if traffic in the wireless network is low. Afterwards, the contention window range of the client device is reduced if either of the wireless network is small or if the traffic in the wireless network is low.

摘要： A method for load balancing incoming data packets in a server computer system adapted to have a plurality of network interface cards coupled thereto and communicatively coupled to client computer systems in a network. A first media access control (MAC) address for a first NIC is selected using a load balancing scheme. A first directed data packet containing the first MAC address and a network address for the server computer system is sent to a first client computer system. The first MAC address and the network address are stored in a protocol cache of the first client computer system. A second MAC address for a second NIC is also selected using the load balancing scheme. A second directed packet containing the second MAC address and the network address is sent to a second client computer system. The second MAC address and the network address are stored in a protocol cache of the second client computer system. Thus, the server computer system will receive an incoming data packet from the first client computer system over the first NIC and from the second computer system over the second NIC.

摘要： A method includes operating a computing device in a first power mode and a first operating state. The first operating state includes first operating state information stored in a volatile memory. The method includes receiving a first request to change the power mode from the first power mode to a second power mode. In response to receiving the first request, a sub-portion of the first operating state information that includes less than all of the first operating state information is stored in a non-volatile memory. The method includes receiving a second request to change the power mode from the second power mode to the first power mode. In response to receiving the second request, the computing device is restored to the first power mode, and is placed in a second operating state, by re-creating a portion of the first operating state information.

摘要： A method for selecting a network interface card (NIC) to be used to send and receive data packets in an Internetwork Protocol Exchange (IPX) environment using a server computer system having a plurality of NICs coupled thereto. An outgoing data packet is addressed using an IPX address and a socket number. A load balancing scheme is executed in order to select a NIC from the plurality of NICs. In one embodiment, the load balancing scheme is a function of the IPX address; in alternate embodiments, the load balancing scheme is a function of the IPX address and either the destination or source socket number. The media access control (MAC) address that represents the selected NIC is inserted in the outgoing data packet. The data packet is then sent using the selected NIC. In one embodiment, the present invention also provides a system and method for fault tolerance and fail over support. The plurality of NICs each include a filter that is adapted to mask a portion of a MAC address in an incoming data packet received at a NIC such that the MAC address in the incoming data packet is equivalent to the MAC address representing the NIC.

摘要： A computer-implemented computer shut-down method includes identifying that a computing device has been moved from an open configuration in which input and output mechanisms on the computing device are accessible to a user, to a closed configuration in which at least some of the input and output mechanisms are inaccessible to a user; starting a shut-down timer in response to identifying that the computing device has been moved from the open configuration to the closed configuration; waiting a predefined time period, as established by the shut-down timer, and determining from the shut-down timer that the computing device can be transitioned from an active state into a sleep state in which power consuming components of the computing device are powered down; and transitioning the computing device from the active state to the sleep state upon determining that the computing device can be transitioned.
