    摘要： Methods and systems are provided for improving a firewall implemented at a WLAN infrastructure device (WID). The WID includes a stateful firewall that implements firewall rules based on an ESSID of the WID to specify whether traffic is allowed to or from the ESSID. For example, in one implementation of such a firewall rule, packets that are required to be sent out on all wired ports can be blocked from being flooded out on WLANs (e.g., the packet is allowed to pass only to the wired ports). A method and system are provided for preventing a malicious wireless client device (WCD) that is transmitting undesirable traffic from using RF resources by deauthenticating the malicious WCD to remove it from the WLAN and blacklisting it to prevent it from rejoining the WLAN for a time period. Method and systems are also provided for either “on-demand” and/or predicatively communicating state information regarding an existing firewall session.

    摘要： A system for correcting distortion effects in a distorted image includes a memory controller for reading pixels (corresponding to a subset region in a destination image) of the distorted image from a system memory to local memory. A look-up table stores an offset and interpolation weight for each pixel, and an ALU computes, using stored values only in the local memory, values of each of the pixels in the region in the destination image.

    摘要： Increased security may be provided on an enterprise network by causing a central security server to administer security policy on the network. Agents in hosts on the network authenticate with the central security server to obtain policy information for that particular host user. The policy information may specify whether any special routing, processing, or other features, should occur in connection with particular classes of traffic or in connection with communications with particular other hosts or classes of hosts. In operation, the agents implement the policy by interfacing with the networking layer to cause the traffic to be routed via any other host/server on the network so that appropriate services may occur with respect to that traffic. Additionally, tunnels may be established so that traffic in-between hosts or between a host and server to be encrypted, compressed, or otherwise treated as specified in the policy.
