摘要： Techniques for determining a problem location or otherwise characterizing a network comprising a plurality of processing elements, including at least one processing element associated with performance of a packet encapsulation operation of an encapsulation protocol. The packet encapsulation operation is performed on a test packet to generate an encapsulated packet, the test packet having a time to live (TTL) value and an identifier. In conjunction with performance of the packet encapsulation operation, the TTL value and the identifier of the test packet are copied to a header of the encapsulated packet. The encapsulated packet is transmitted, and a determination is made as to whether a reply packet has been received responsive to transmission of the encapsulated packet. The reply packet, if any, is processed to obtain information utilizable in determining the problem location or otherwise characterizing the network. By way of example, these operations may be repeated, for subsequent test packets with increasing TTL values, until an amount of router hop information sufficient to determine the problem location is obtained.

摘要： During operation, a client node can receive a network's topology. Next, the client node can detect a change in an interface's state. The client node can then create an interface state change message which indicates the change in the interface's state. Next, the client node can send the interface state change message to the master node, which can cause the master node to notify other client nodes about the change in the interface's state. If a client node's copy of the link state database (LSD) is out of sync with the master node's LSD, the client node can request the master node to send a full LSD update message to the client node. The master node can multicast messages to the client nodes, and each node in the network can include one or more interfaces that are dedicated for sending and receiving control messages, thereby creating a separate control network.

摘要： Methods and systems to implement voltage level shifting with interim-voltage-controlled contention-interruption. A voltage level shifter (VLS) may include voltage level shift circuitry to level shift an input logical state from an input voltage swing to an output voltage swing. The VLS may include contention circuitry, a contention interrupter, and an interrupt controller to generate a contention-interrupt control having an interim voltage swing. A lower limit of the interim voltage swing may correspond to a lower limit of the output voltage swing. An upper limit of the interim voltage swing may correspond to an upper limit of the input voltage swing. The VLS may be implemented to level shift true and complimentary logical states, such as with cascode voltage switch logic (CVSL). The interim-voltage-controlled contention interrupter may help to maintain voltages within process-based voltage reliability limits of the contention interrupter, with relatively little delay, and relatively little power and area consumption.

摘要： The pricing of a product is programmatically managed by defining a plurality of pricing states for the product. Each pricing state has a pricing mechanism associated therewith. A pricing mechanism can be a variable pricing mechanism such as an auction. It can also be a fixed pricing mechanism for the sale, rental, or subscription of the product. One or more triggers are defined, each of which may include one or more trigger parameters, to enable the pricing of the product to transition from one pricing state to another pricing state. In this manner, an automated, systematic approach to pricing management is provided.
