Lookup Table Arrangement And Related Management Method For Accommodating Concurrent Processors

View page
US Patent:
8271564, Sep 18, 2012
Filed:
Jul 14, 2008
Appl. No.:
12/172780
Inventors:
Nicolas Sebastien Dade - Santa Cruz CA,
Assignee:
Symbol Technologies, Inc. - Holtsville NY
International Classification:
G06F 7/00
G06F 17/00
US Classification:
707999008, 707698
Abstract:
A system and methods of managing entries in a cuckoo hash table that is subject to manipulation by a plurality of concurrent processors are provided. The cuckoo hash table is used to maintain a plurality of keys, along with their data items, in a plurality of entries. In accordance with an operating method, a first command for the cuckoo hash table is processed, and the first command is associated with a first processor of the plurality of concurrent processors. In addition, invalid conditions associated with concurrent processing of a second command for the cuckoo hash table are prevented or minimized. The second command is associated with a second processor of the plurality of concurrent processors. As one example, the operating method manages the situation where concurrent push commands create a race condition. As another example, the operating method manages the situation where a lookup or delete command from one processor competes with a push command from another processor.

Wireless Switches With Jtag Emulators

US Patent:
2007025, Nov 1, 2007
Filed:
Apr 30, 2007
Appl. No.:
11/742231
Inventors:
Edward Geiger - San Martin CA,
Nicolas Dade - Santa Cruz CA,
Assignee:
SYMBOL TECHNOLOGIES, INC. - Holtsville NY
International Classification:
H04B 1/40
US Classification:
455436
Abstract:
A wireless switch includes a multi-core processor comprising a first core and a second core, and a JTAG emulator coupled to the first core and the second core. The JTAG application of the first core is adapted to debug the second core via the JTAG emulator.

Apparatus And Method For Booting A Computing Device From A Nand Memory Device

View page
US Patent:
2007026, Nov 8, 2007
Filed:
Apr 30, 2007
Appl. No.:
11/741953
Inventors:
Nicolas Dade - Santa Cruz CA,
Edward Geiger - San Martin CA,
Assignee:
SYMBOL TECHNOLOGIES, INC. - Holtsville NY
International Classification:
G06F 9/00
US Classification:
713 2
Abstract:
Apparatus and methods are provided for booting a computing device from a NAND flash memory. One apparatus includes a NAND memory device including a boot sector configured to store boot code and an FPGA including an internal memory in communication with the NAND memory device. The FPGA is configured to access the boot sector and load the boot code into the internal memory. A method for booting a computing device having a processor, an FPGA, and a NAND memory device including at least one sector storing boot code and a sector storing operational code includes the steps of the FPGA holding the processor in reset and accessing the boot sector. The FPGA also fetches the boot code from the boot sector and stores the boot code in its internal memory. Also disclosed are machine-readable mediums providing logic, which when executed by an FPGA, causes the FPGA to perform the method.

Wireless Local Area Network Infrastructure Devices Having Improved Firewall Features

View page
US Patent:
2011016, Jun 30, 2011
Filed:
Dec 30, 2009
Appl. No.:
12/649532
Inventors:
Rajesh Vijayakumar - San Jose CA,
Nicolas S. Dade - Santa Cruz CA,
Jacob Thomas - San Jose CA,
Anurag Verma - Bangalore,
Assignee:
Motorola, Inc. - Schaumburg IL
International Classification:
G06F 17/00
US Classification:
726 13, 726 11
Abstract:
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.

Transmission Control Protocol Optimization Systems And Methods For Wireless Networks

US Patent:
2012016, Jun 28, 2012
Filed:
Dec 27, 2010
Appl. No.:
12/978893
Inventors:
Nicolas S. Dade - Santa Cruz CA,
Assignee:
SYMBOL TECHNOLOGIES, INC. - Schaumburg IL
International Classification:
H04L 12/26
US Classification:
370229
Abstract:
The present disclosure provides systems and methods improving Transmission Control Protocol (TCP) network congestion avoidance in wireless networks. Specifically, the present disclosure decouples wired and wireless TCP connections at a wireless access point, thin access point, wireless switch, etc. The wired TCP session is terminated on the wireless access device and a wireless TCP session is automatically started for the last hop to a mobile unit. Advantageously, the wireless TCP session may utilize a congestion avoidance algorithm optimized for wireless network. Furthermore, wireless local area network (WLAN) information may be tied to the TCP stack for improved performed, e.g. an IEEE 802.11 Acknowledgement (ACK) may be considered as equivalent to a TCP ACK from the mobile unit. By splitting a TCP downstream connection into two—wireless and wired, high-jitter, high-loss wireless hops may be hidden from the remote host's TCP socket.

Transitioning A State Of A Connection In Response To An Indication That A Wireless Link To A Wireless Device Has Been Lost

US Patent:
8023985, Sep 20, 2011
Filed:
Jun 7, 2004
Appl. No.:
10/862514
Inventors:
Helge Szwerinski - Cupertino CA,
Nicolas S Dade - Santa Cruz CA,
Vibhu Vivek - Fremont CA,
Kumara Das Karunakaran - Santa Clara CA,
Assignee:
Nortel Networks Limited - St. Laurent, Quebec
International Classification:
H04B 7/00
H04B 1/00
US Classification:
455522, 455 69, 4554351, 455515, 455434, 455401
Abstract:
A method and apparatus of establishing a connection between a wireless device and a second device includes maintaining a state of the connection between the wireless device and the second device, and receiving an indication that a wireless link to the wireless device has been lost or may be lost. In response to the receiving the indication that the wireless link to the wireless device has been lost or may be lost, the state of the connection is transitioned from a first state to a second state.
