Control over the movement of packets is exercised by edge nodes of a network mapping the addresses of incoming packets in accordance with a prespecified functional mapping P. Remote sources of packets are provided address information that is mapped with a prespecified functional mapping Q, where mappings P and Q are such that P(Q(j)=j. The mapping change at regular intervals, or upon the occurrence of specified events, and with each change, the communicating the remote source is provided with a different mapped address to be used.

A method of automatically matching schemas begins by extracting schemas from sources and targets. Then, source and target attributes are extracted from the schemas. Each source schema will have multiple source attributes and each target schema will also have multiple target attributes. The source attributes and the target attributes are presented as nodes in a bipartite graph. This bipartite graph has edges between nodes that are related to each other. A plurality of similarity scores are defined between each set of related nodes. Each of the similarity scores is based on a different context-specific cue of the attributes that the nodes represent. These context-specific cues can comprise lexical name, semantic name, type, structure, functional mappings, etc. An overall weight is computed for each edge in the bipartite graph by combining the similarity scores of each set of nodes that form an edge.

A configuration for a programmable device is determined to implement an incomplete function using at least two logic cells. Function inputs are partitioned into portions associated with first and second logic cells. The partitioning is screened to determine if it is potentially acceptable by determining if a portion of the function can be implemented using a complete look-up table. If the partitioning of the function inputs is potentially acceptable, the function inputs are assigned to the input ports of the logic cells. Variables are assigned to look-up table locations and a correspondence is determined between function input and output values, the variables, and the look-up table locations. Boolean tautology rules are applied to the correspondence to simplify the variables. If the simplified variables are consistent, a configuration is output that includes assignments of function inputs to input ports and look-up table data based on the simplified variables.

The invention discloses a method for optimizing the fair allocation of dominant resources in the Internet of Vehicles based on a utility function. Firstly, a utility function with QoS indicators (packet delay and packet loss rate, etc.) as independent variables is constructed; and then the M / D The / 1 queuing model establishes the functional mapping relationship between the QoS index and the number of wireless network resources (bandwidth and cache, etc.); then designs an allocation algorithm for a dominant resource fairness mechanism, aiming at maximizing vehicle user utility, and assisting The user's dominant resources are allocated fairly and reasonably based on user weight priority. The utility function of the present invention can effectively represent the satisfaction degree of the user to the service. By establishing a mapping model for the QoS index and the resource quantity, the user's QoS performance requirement can be converted into the required resource quantity to be allocated. While allocating on-demand, it maximizes user satisfaction with QoS requirements, improves user priority, and maximizes resource utilization.
