In one embodiment, this can be accomplished by storing temporarily jobs form a plurality of queues, where each queue a weight is set up, forming a set of elements, wherein the set size is based on the weights assigned to each queue, selecting one element from the formed set in an order, wherein the order can be predefined or random order and serving at least one job from the plurality of queues, wherein selection of the job is from the queue that corresponds to element of the formed set. | 03-21-2013 |
20120002682 | METHOD TO TRANSMIT MULTIPLE DATA-STREAMS OF VARYING CAPACITY DATA USING VIRTUAL CONCATENATION - Instant discloser is a method to transmit multiple data-streams of varying capacity data using Virtual Concatenation (VCAT) over Synchronous Digital Hierarchy (SDH) network, comprising acts of determining number of data bytes to be requested for each Virtual Concatenation Group (VCG) in a row-time of the aggregated bandwidth and storing it in a VCG request configuration memory, reading the requested number of data bytes from each data-stream in order in to a Row Buffer for each row time of an SDH frame, reading data stored in the Row Buffer from memory address determined by one or more connection memory wherein the connection memory is programmed to carry out sequencing of bytes of the Row Buffer based on the VCAT numbering, and inserting path overhead (POH) and pointer information in to the read data streams in previous step to transmit multiple data-streams of varying capacity data using VCAT over SDH network. | 01-05-2012 |
20100290367 | Method to Develop Hierarchical Ring Based Tree for Unicast and/or Multicast Traffic - The present invention provides a novel method for hierarchy of preplanned protected path for both node and link failure in the realm of Carrier Ethernet Technology. In the event of failure in a hierarchy, the traffic is switched from work (primary) path to protected (secondary) path. If such path does not exist within a given hierarchy then traffic is routed through multiple hierarchies until SLA is met YES or no path exists. Hierarchies make the network fault resilient. | 11-18-2010 |
