چکیده

In this paper, we present subcaching, a method for reducing the size of the caches in the recursive decomposition while maintaining the runtime of recursive conditioning with complete caching. We also demonstrate a heuristic for constructing recursive decompositions that improves the effects of subcaching, and show empirically that the savings in space is quite substantial, with very little effect on the runtime of recursive conditioning.

CQP-Miner: Mining Conserved XML Query Patterns For Evolution-Conscious Caching

Existing xml query pattern-based caching strategies focus on extracting the set of frequently issued query pattern trees (qpt) based on the support of the qpts in the history. These approaches ignore the evolutionary features of the qpts. In this paper, we propose a novel type of query pattern called conserved query paths (cqp) for efficient caching by integrating the support and evolutionary f...

Efficient Setup for Multicast Connections Using Tree-Caching

* Corresponding author. AbstractThe problem of finding a minimum-cast multicast tree ( Steiner tree) is known as NP-complete. Heuristic-based algorithms for this problem to achieve good performance are usually time-consuming. In this paper, we propose a new strategy called tree-caching for efficient setup of multicast connections in connection-oriented networks. In this scheme, the tree topolog...

In-Network Caching vs. Redundancy Elimination

Network-level Redundancy Elimination (RE) techniques have been proposed to reduce the amount of traffic in the Internet. and the costs of the WAN access in the Internet. RE middleboxes are usually placed in the network access gateways and strip off the repeated data from the packets. More recently, generic network-level caching architectures have been proposed as alternative to reduce the redun...
