摘要： Method and apparatus for dynamically allocating IP addresses in a wireless IP network. IP address servers determine the requisite IP address pools and guard bands for individual network cells to guarantee fair access to the network and facilitate handoff host handoff from a prior cell to a new cell. IP address servers also prioritize handoff and resident hosts that request an IP address from the IP address server. In particular, IP address servers assign a higher priority to handoff hosts over resident hosts that request an IP address from an IP address server in order to maintain a preestablished handoff host network connection instead of dropping a handoff host connection in favor of a new resident host network connection. Finally, each cell is allocated a minimum number of IP addresses to ensure a certain level of fair access to the network regardless of the cell wherein a handoff or resident host resides.

摘要： A virtual structured information system or a virtual database is developed and presented in the framework of an information theory for multiple source information systems such as databases. A virtual tree structure is built from virtual nodes in main memory which contain no raw data. The virtual nodes and virtual trees provide general non-data virtual structure, like cross-table nodes, for systematic information manipulations such as on-line analytical processing in a structured information system.

摘要： Mechanisms are provided for arranging binary code to reduce instruction cache conflict misses. These mechanisms generate a call graph of a portion of code. Nodes and edges in the call graph are weighted to generate a weighted call graph. The weighted call graph is then partitioned according to the weights, affinities between nodes of the call graph, and the size of cache lines in an instruction cache of the data processing system, so that binary code associated with one or more subsets of nodes in the call graph are combined into individual cache lines based on the partitioning. The binary code corresponding to the partitioned call graph is then output for execution in a computing device.
