摘要： System flexibility and ease-of-design is greatly enhanced in a network wireless/RFID switching device by using a multicore abstraction layer (MCAL) to interface between a multicore hardware platform, a device operating system and the packet transfer functions of the system. Such an architecture may be particularly useful in constructing switches capable of switching wireless networking (e.g. IEEE 802.11, 802.16), RFID or other network protocols, particularly using multi-core processors. A classification handler initially classifies the data packet. A plurality of protocol handlers each associated with a data protocol processes the data packet if the classification of the data packet matches the data protocol associated with the protocol handler, and one of several application handlers each associated with a user applications processes the data packet if the classification of the data packet matches the user application associated with the application handler. The MCAL is configured to send the data packet to the classification handler after the packet is initially received, and to subsequently direct the packet toward one of the protocol or application handlers in response to the classification of the data packet. MCAL further contains a set of the containers for handlers. Real application, protocol and classification handlers register with MCAL and are modules developed outside of the MCAL.

摘要： System flexibility and ease-of-design is greatly enhanced by using a multicore abstraction layer (MCAL) to interface between a multicore hardware platform, a device operating system and the packet transfer functions of the system. Systems and techniques are described for processing a data packet received at a network interface of a network infrastructure device (such as a wireless switch) or other computing system, particularly using multi-core processors. A classification handler initially classifies the data packet. A plurality of protocol handlers each associated with a data protocol processes the data packet if the classification of the data packet matches the data protocol associated with the protocol handler, and one of several application handlers each associated with a user applications processes the data packet if the classification of the data packet matches the user application associated with the application handler. The MCAL is configured to send the data packet to the classification handler after the packet is initially received, and to subsequently direct the packet toward one of the protocol or application handlers in response to the classification of the data packet. MCAL further contains a set of the containers for handlers. Real application, protocol and classification handlers register with MCAL and are modules developed outside of the MCAL.

摘要： A handheld device (e.g., an RFID reader, mobile computer, or the like) is configured to periodically scan its environment for the presence of RFID tags, determine whether any of the RFID tags within range include a valid security code, then disable operation (e.g., by preventing access to stored data) when it is determined that there are no RFID tags with a valid security code within the operational range. The RFID tags may be placed strategically at secure locations within the environment, such as within other network devices (access ports, switches, etc.).

摘要： A method for automated testing of a device (e.g., a router, switch, mobile terminal, barcode reader, or the like) includes creating a metafile, establishing a network connection to the device, parsing the metafile to determine a device command and an expected result, apply a terminology substitution process to the device command based on a terminology block associated with the device, thereby creating a modified device command; issuing the modified device command to the command line interface of the device via the network connection; receiving a response from the command line interface of the device via the network connection; comparing the response to the expected result, then logging, to a test summary file, a test result based on the comparing step. The metafile language has a relatively simple vocabulary and syntax, and is thus easy to learn and implement.

摘要： Wireless switches in a cluster are managed by providing a configuration server for storing common configuration files and a DHCP server for storing cluster-specific configuration files corresponding to each cluster. A method for configuring the wireless switches then includes requesting, from the DHCP server, an IP address for the wireless switch; receiving, from the DHCP server, the IP address and the cluster-specific configuration file; receiving, from the configuration server, the common configuration file; and executing, at the wireless switch, the cluster-specific configuration file and the common configuration file.

摘要： A wireless data communication system includes an access port configured to wirelessly communicate with a plurality of mobile units within multiple basic service sets (BSS), and a wireless switch having multiple predefined wireless local area networks (WLANs). The wireless switch is configured to automatically map the WLANs to the basic service sets and transmit to the access port a configuration template depending upon the type of access port. In one embodiment, there are n basic service sets, each having a corresponding basic service set identifier (BSSID), and m WLANs, each having a corresponding WLAN index, wherein the m WLAN indices are uniformly mapped to the n BSSIDs such that each BSSID has substantially the same number of WLAN indices mapped thereto. In a particular embodiment, there are n=4 BSSIDs per access port and m=16 pre-mapped WLANs. In this way, the wireless switch and respective access ports can be set-up in a simplified manner, in much the same way that set-up is performed with traditional access points.
