摘要： An enhanced, flooding-based link state routing protocol is described that provides pruning of link state data and, when needed, rate-controlled refresh of the pruned link state data from other routers of the flooding domain. A routing device comprises a network interface to send and receive packets over a layer-two (L2) communication medium. The routing device includes a control unit coupled to the network interface, and a flooding-based link state routing protocol executing on a processor of the control unit. The link-state routing protocol establishes an adjacency with a peer router. A database of the routing device includes entries that store a plurality of link state messages for a flooding domain of the link state routing protocol, wherein at least one of the entries in the database stores a partial link state message having a header portion and a payload having pruned link state data.

摘要： An enhanced, flooding-based routing protocol is described that provides burst-rate and average-rate flow control. A routing device comprises a network interfaces configured to send and receive packets over a layer-two (L2) communication medium. A flooding-based link state routing protocol executes on a processor of the routing device to maintain network topology information for a network and establish an adjacency with a peer router over the layer-two (L2) communication medium. A database of the routing device stores a minimum packet interval and a credit specified by the peer router for the adjacency. When sufficient credit has been allocated to the L2 communication medium, a scheduler of the router dequeues link state messages from an outbound packet queue and floods each of the link state messages to the L2 communication medium while maintaining at least the specified minimum packet interval between each of the plurality of link state messages.

摘要： Disrupting a biological cell includes freezing, boiling or perhaps alternately freezing and boiling material containing the biological cell using a thermoelectric cell with a working face, and a base face whereof is contiguous with a heat source/sink at a substantially constant temperature. Apparatus for the disruption process includes a peltier cell, a base face, which is flexibly attached to a heat source/sink held at a constant temperature, and a working face contiguous with a reaction vessel or holder thereof. Reversal of the voltage in the peltier cell enables the working face alternately to reach below freezing and above boiling temperatures, and/or with use of a resistive wire on the vessel or holder for heating, with the TEC used purely for cooling. The materials of the base face tend to inhibit disintegration of the peltier cell brought about by expansion and contraction by heat.

摘要： Systems, methods, software for monitoring usage of a recording medium in an image forming apparatus. In one embodiment, a usage monitor receives a raster image, and identifies thresholds that distinguish different intensity levels reproduced by different drop sizes of the recording material. The usage monitor identifies a set of pixel values for a block of pixels from the raster image, performs a vectorized comparison of the set of pixel values to each of the thresholds to generate sets of comparison bits, determines a number of set bits in each of the sets of comparison bits, and updates a threshold counter for each of the thresholds based on the number of set bits. The usage monitor may then compute drop counts for different drop sizes based on the threshold counter for each of the thresholds.

摘要： Embodiments herein describe a two-phase printing process that utilizes page-to-resource tracking during the first rip-to-spool phase in order to perform resource scheduling during the second print-from-spool phase. In one embodiment, compute nodes include a RIP and a raster builder. A controller receives a print job, identifies a distribution of logical pages in the print job to the compute nodes, and generates page assignment information that maps the logical pages to the compute nodes based on the distribution. The compute nodes rasterize the logical pages to generate intermediate data using the RIPs, and store the intermediate raster data at a RIP spool. The controller directs a distribution of the intermediate raster data from the RIP spool to the compute nodes based on the page assignment information, and the compute nodes assemble the intermediate raster data into complete raster data using the raster builders.

摘要： System and methods for processing and printing print jobs with a single sheet job model job model. In one embodiment, a print controller includes an interface that receives a print job, and a processing unit that initiates a processing task for a group of pages in the print job. The print controller also includes a sheet controller that establishes a single sheet job model in memory for the processing task, and that iteratively inserts sheet properties of a set of pages of the group into the single sheet job model, provides the single sheet job model with the sheet properties to the processing task, and erases the sheet properties from the single sheet job model.

摘要： In one example, a network device receives a packet to be forwarded according to a label switching protocol, determines a service to be performed on the packet by a service network device, sends a label request message to the service network device, wherein the label request message indicates support for labels having a particular length, wherein the particular length is larger than twenty bits (e.g., forty bits), and wherein the label request message specifies the service to be performed on the packet, receives, in response to the label request message, a label mapping message defining a label of the particular length, appends the label to the packet to form a Multi-Protocol Label Switching (MPLS)-encapsulated packet, and forwards the MPLS-encapsulated packet according to the label switching protocol.

摘要： Systems and methods are provided for labeling inserted pages within a print preview of a print job. The system receives print data comprising logical pages, and receives instructions for inserting pages among the logical pages of the print data. The system further receives a request for a print preview for the print data, identifies inserts for the print data based on the instructions, rasterizes the logical pages of the print data and the inserts to generate sheet images for the print preview, and includes non-printing marks in the sheet images for the inserts that distinguish the inserts from rasterized logical pages of the print data. The system further transmits the sheet images of the print preview.
