Filed:

Jan 22, 2009

Appl. No.:

12/358050

Inventors:

Heather D. Achilles - Hudson NH, US
Joseph H. Allen - Belmont MA, US
David J. Hoeweler - Cambridge MA, US
Jeffrey M. Peters - Leominster MA, US

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G06F 17/00

US Classification:

715234, 715235, 715236

Abstract:

A method, computer program product, and system are disclosed for supporting variable data structures and constant data structures in a hardware-based XML PPE. The method may include inserting one or more constant Type-Length-Attributes (TLAs) into an output stream. The constant TLAs are inserted from one or more constant node-sets referenced from a constant table. The method may also include creating one or more variable node-sets. Each variable node-set includes one or more variable TLAs (TLAs saved from a base XML document) and is mapped to a variable table. The method may also include inserting one or more variable TLAs into the output stream inserted from one or more variable node-sets referenced from the variable table.

International Classification:

G06F 9/455

US Classification:

703 26

Abstract:

The system and method of the present invention “emulates” the TCAM function using a data structure which is stored in an SDRAM device in such way that the size of emulated TCAM is substantially larger than the original TCAM device, thereby allowing the increase of the number of PPE programs which can be resident in memory. The present invention provides a new “emulCAM” algorithm which builds partially on BaRT, but is extended by providing multiple results per hash table entry with flexible assignment to “match-condition-combinations”, by utilizing MUX control vectors for extracting hash index instead of “index-mask-based extraction”, by moving part of CAM function to invoking emulCAM instruction and by providing “Pathological case handling” using multiple emulCAM instructions.

International Classification:

H04L 12/56

US Classification:

370252, 370400, 370328

Abstract:

Methods and apparatus for direction routing between nodes of networks are disclosed. An example method includes identifying a destination node of first data received at a first node; calculating a logical distance from the first node to the destination node; and, when the logical distance meets a threshold condition and when a direct route from the first node to the destination node is blocked according to a protocol setting, overriding the protocol setting to enable transmission of the first data from the first node to the destination node via the direct route.

International Classification:

H04L 41/0813
H04L 41/08
H04W 12/50
H04W 12/102

Abstract:

An example computing device is configured to (i) establish a connection to a secure wireless network (ii) determine that one or more playback devices of a media playback system are not connected to the secure wireless network (iii) receive, via a graphical display, a user input indicating a request to update the one or more playback devices with network configuration parameters for the secure wireless network, (iv) retrieve, from storage, a list of the one or more playback devices, (v) receive an input indicating a first playback device to be updated from the list, (vi) establish an initial communication path with the first playback device, (vii) transmit a set of one or more messages to the first computing device collectively comprising the network configuration parameters for the secure wireless network, and (viii) receive an indication that the first computing device has established a connection to the secure wireless network.

International Classification:

H04R 27/00
H04R 29/00

Abstract:

Low-latency audio networking is disclosed. In one embodiment, an example playback device includes a processor and memory having stored thereon instructions executable by the processor. The example instructions are to cause the first playback device to perform functions comprising: receiving audio information; selecting a first frequency channel of a first spectrum based on a threshold latency associated with the audio information; transmitting to the second playback device via a second frequency channel of a second spectrum, control information that identifies the first frequency channel of the first spectrum; and transmitting to the second playback device via the first frequency channel of the first spectrum, the audio information to be played by the second playback device.
