Abstract: This disclosure describes techniques operating a client device to communicate with a wireless access point. The client device may awake from a low power mode of operation receive a first portion of a beacon from the access point that includes a delivery traffic identification (DTIM) message. According to the techniques described herein, the client device may determine, based on the DTIM message, whether or not one or more packets of data are forthcoming from the access point. If one or more packets of data are forthcoming from the access point, the client device may remain in an active mode of operation to receive the forthcoming packets (and/or a second portion of the beacon). However, if no packets of data are forthcoming from the access point, the client device may return to the low power mode of operation, before receiving and/or processing the second portion of the beacon.

Abstract: The present invention provides a system and method that operates in the link layer and detects connection status in a LAN. The system includes a request frame whose source address is an address of a node transmitting the request frame, a reply frame whose destination address is the source address of the request frame, and a first node and a second node within the LAN for processing the request/reply frame. The method includes the first node transmitting a request frame into the LAN, the second node transmitting a reply frame to the first node if receiving the request frame, and the first node checking whether a destination address of the reply frame comprises an address of the first node when receiving the reply frame. If so, the connection between the first and second nodes is in a normal state.

Abstract: A method used for routing a data packet in a router having a first table used for recording a plurality of destination IP address and second table used for recording destination MAC address, wherein the plurality of destination IP address are different. The method includes: receiving a data packet and retrieving a destination IP address from the data packet; looking up an indication value corresponding to the destination IP address from the first table; selecting a destination MAC address from the second table according to the indication value as a nexthop for the data packet; and transmitting the data packet to the nexthop.

Abstract: The present invention provides an apparatus and method for NAT/NAPT session management used in a network switch controller. The apparatus comprises a translation table for storing related information of NAT/NAPT sessions, a register for storing setting values required by the apparatus, and a control logic for managing the NAT/NAPT sessions based on the setting values stored in the register and the related information in the translation table. The apparatus offers a connection time to each NAT/NAPT session and decreases it every unit time. When it is reduced to zero, the related information of the session is invalidated and the session is then disconnected. The apparatus stores related information of NAT/NAPT sessions and offers associated connection time and unit time based on the protocols used, thereby invalidating the related information timely to empty part of the translation table for storing related information of other sessions.
