Abstract: A system and method for providing automated bottleneck identification in networks and networked application environments by processing using end-to-end quality of service measurements in combination with knowledge of internal resource dependency information generated by a network administrator. In one aspect, a method for identifying bottleneck resources in a network having a plurality of resources comprises the steps of: specifying a plurality of probe transactions in the network; generating resource dependency information representing dependent resources for each of the probe transactions; executing the probe transactions; measuring end-to-end quality of service data resulting from the executing of the probe transactions; and processing the resource dependency information and measured end-to-end quality of service data to identify bottleneck resources in the network.

Abstract: A structure and technique are provided for improving the average access time in a bubble lattice file (BLF) storage, and for providing reordering capability in the lattice file. The bubble lattice arrangement includes a translation structure for moving bubble domains in the lattice to various access channels where columns of bubble domains can be removed from the lattice. These are double access channels which remove two adjacent columns of bubble domains at the same time. A read means and a write means are associated with each channel of the double channel access for reading the information in each column removed from the lattice, and for writing new information into these columns. A transposition structure is provided for transposing the information represented by bubble domains in each of the removed columns, in response to a signal from associated control circuitry.
