Abstract:
A packet is classified into a class. A priority value is assigned to the packet wherein packets in a flow are assigned priorities according to some probability distribution within some band. A determination is made, at a network device for a highest latency class, whether a sum of queued packet sizes of previously received packets having an equal or smaller latency class than the packet and larger or equal priority than the packet is larger than a threshold value. When the sum is larger, the packet is dropped, otherwise a determination is made whether a latency class of the packet is less than the latency class of the network device. When the latency class is not less, the packet is stored in a queue for the latency class. When the latency class is less, then the process is repeated until the packet is dropped or stored in a queue.

US Classification:
37039542, 3702301, 370231, 37039521
Abstract:
A method, apparatus and computer program product for non-uniform per-packet priority marking for use with adaptive protocols is presented. A packet is received at a first network device, the packet assigned to a priority band. A priority is determined for the packet between a lowest priority of the priority band and a highest priority of the priority band, the priority for the packet selected based on a target distribution of priorities within the priority band, the target distribution comprising a distribution selected to achieve a desired capacity relationship among groups of packets assigned to different priority bands. The selected priority is assigned to the packet.
Method And System For Converting Files To A Specified Markup Language
INTERNATIONAL BUSINESS MACHINES CORPORATION - ARMONK NY
International Classification:
G10L015/28
US Classification:
704/255000
Abstract:
A method and system for converting a delimited flat file to a markup language specified by a document type definition file. The method comprises the steps of providing a delimited flat file having columns with headings, and providing a map file conforming to said document type definition file and having tags and attributes including references matching said headings. A tree structure is formed from the map file, with each tag representing one or more nodes of the tree. The tree structure is traversed, node-by-node, and for each node, the attributes are entered into said markup language file. When the attributes include one of said references, text is retrieved from one of the columns with one of the matching headings of the flat file, and that text is entered into the markup language file.
Rf Repeater And Method For Semantic-Less Retransmissions
Embodiments of a radio-frequency (RF) repeater configured for semantic-less retransmissions are described herein. The RF repeater performs physical (PHY) layer processing to identify one or more PHY layer features of a received RF signal. The RF repeater may determine whether or not to retransmit the received RF signal based on the one or more PHY features. The determination to retransmit the received RF signal may be based solely on PHY parameters enabling semantic-less retransmissions.
