摘要： Techniques are described for distributing network device tasks across virtual machines executing in a computing cloud. A network device includes a network interface to send and receive messages, a routing unit comprising one or more processors configured to execute a version of a network operating system, and a virtual machine agent. The virtual machine agent is configured to identify a virtual machine executing at a computing cloud communicatively coupled to the network device, wherein the identified virtual machine executes an instance of the version of the network operating system, to send, using the at least one network interface and to the virtual machine, a request to perform a task, and to receive, using the at least one network interface and from the virtual machine, a task response that includes a result of performing the task. The routing unit is configured to update the network device based on the result.

摘要： Systems and methods are provided for implementing adaptive rasterized print data management. The printing system is able to acquire a print job and instructions for printing multiple copies of the job. The control unit is also able to initiate processing of a first copy of the print job, to instruct a Raster Image Processor (RIP) to rasterize a data segment of the print job, and to determine a transfer time to transfer the rasterized data segment to a marking engine if it were stored at the first memory. Further, the control unit is able to determine a threshold value, and to facilitate storage of the rasterized data segment at the second memory if the transfer time is greater than the threshold value.

摘要： A process for the disruption of a biological cell comprising freezing, boiling or perhaps alternately freezing and boiling the material containing the biological cell using a thermoelectric cell a base face whereof is contiguous with a heat sink/source held at a substantially constant temperature and a working face . Apparatus for carrying out the disruption process comprises a peltier cell a base face of which is flexibly attached to a heat sink arranged to be kept at a constant temperature of around 50° C. and a working face of which is contiguous with a reaction vessel or a reaction vessel holder. 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 holder for heating with the TEC used purely for cooling The peltier cell base face is constructed of materials which tend to inhibit disintegration of the peltier cell brought about by expansion and contraction under heat.

摘要： A method is disclosed for dynamically creating encapsulation and decapsulation chains and segmenting the packet-forwarding plane. A distributed router may comprise multiple cards, each exposing a subset of the router's physical interfaces. Some physical interfaces may be configured to send/receive only certain types and destinations of data packets. Some cards might not expose any physical interfaces configured to send/receive a particular type and destination of packet, making encapsulation and/or decapsulation chains for virtual interfaces that process data packets of the particular type useless on those cards. Therefore, instead of always creating both encapsulation and decapsulation chains for a virtual interface on a card, an aspect of the method dynamically determines which of the encapsulation and decapsulation chains are useful for a virtual interface on that card, and creates only those chains that are useful on that card. Thus, the packet-forwarding plane is segmented into independent encapsulation and decapsulation segments.

摘要： In general, techniques are described for using routing information obtained by operation of network routing protocols to dynamically generate network and cost maps for an application-layer traffic optimization (ALTO) service. For example, an ALTO server of an autonomous system (AS) receives routing information from routers of the AS by listening for routing protocol updates outputted by the routers and uses the received topology information to dynamically generate a network map of PIDs that reflects a current topology of the AS and/or of the broader network that includes the AS. Additionally, the ALTO server dynamically calculates inter-PID costs using received routing information that reflects current link metrics. The ALTO server then assembles the inter-PID costs into a cost map that the ALTO server may provide, along with the network map, to clients of the ALTO service.

摘要： A packer provides multiple seals when deployed downhole. Exposed to an activating agent, a swellable element on the packer's mandrel expands radially outward to form a seal with the borehole wall. Deformable elements, are disposed on the mandrel adjacent the swellable element. These deformable elements deform outward to the surrounding borehole wall to at least partially isolate the downhole annulus and the swellable element. Bias units releasable affixed on the tool adjacent the deformable elements can deform the elements. These bias units can be released either by swelling of the swellable element or by fluid pressure. Once released, the bias units are axially biased toward the deformable elements to deform them. In this way, the packer can form multiple seals with the borehole wall, and the deformable elements can isolate the swellable element from the downhole annulus, which can keep the swellable element from degrading or being overly extruded.

摘要： A downhole tool, such as a packer or liner hanger, has a mandrel on which slips are disposed for engaging a surrounding tubular downhole. When the tool is being run in or out of the hole, at least one magnetic component magnetically retains the slip adjacent the mandrel so the slip can be held away from the surrounding tubular. When the tool is set downhole, the initial magnetic retention can be broken, and the slips can be moved away from the mandrel to engage the surface of the surrounding tubular.
