1 NSF CISE/EIA Research Infrastructure PI Workshop MSI: Research Infrastructure for Integrated Quality of Service (QoS) in Computing Environments A.K. Elmagarmid, A. Ghafoor, T. Korb, K. Park, E. Spafford W. Aref, S. Fahmy, S. Prabhakar, D. Yau Purdue University Project Objective To develop an infrastructure that will integrate key information technologies which include database and storage management, networking, and security in order to support a comprehensive end-to-end QoS management framework for distributed multimedia document applications. End-to to-end QoS User-based QoS Specification Meta Data / User Interface - Reliability - Resolution - Rate of Presentation - Display Area - Temporal Synchronization ( Intra/Inter ) Translation Network OS Database Security - End-to-End Delays - Jitter Delay - Bandwidth - Packet Loss Rate - CPU Throughput - Memory Overflow and Reliability - Storage Throughput/ Bandwidth - Storage Delays - Distributed Database Coordination (QoS) - Intrusion Detection - Access Control Negotiation Dependency Model Analysis and QoS Adjustment End-to-End Run Time Resource End-to-End Resource Allocation and Scheduling Networking 1

2 Research Activities for Document Database and Storage document modeling and QoP specification schema Resolution, reliability, rate, synchronization, processing, contents, security attributes Development of efficient clustering, searching and indexing techniques for multimedia documents Distributed Object Network caching techniques for composition of distributed multimedia objects Omasum Abomasum Reticulum Esophagus Protozoa Rumen Stomach Digestive System Small Intestine Salivary Glands Large Intestine Browsing Graph System Exit The Ruminant Digestive Four compartment stomach that: -utilizes complex carbohydrates such as cellulose -utilizes non-protein nitrogen sources -utilizes feeds of no nutritive value for humans Rumen The rumen, the first compartment of the ruminant stomach, is essentially non - functional at birth but develops rapidly when calves are given solid feeds such as hay and grain. Research Activities for Document Database and Storage data placement and caching techniques for hierarchical storage management system Parallel disk array architecture Clustered server architecture QoS-sensitive real-time disk scheduling techniques for multimedia data Networking 2

3 First Year Experimental Activities for DBMS Architecture for distributed multimedia system has been developed GUI and search engine for content-based retrieval of multimedia documents have been partially implemented Several novel data placement and disk scheduling policies have been developed and implemented on a RAID architecture SHORE and PREDATOR object-oriented systems are being extended to serve as video and multimedia document database management systems Architecture of a Distributed Database Developed Partially developed To be developed Visual Tool for Document Generation Database Client Database Interface API for SBS Network Presentation Subsystem Integrated Information Server Meta Data API for SBS Network Database Server Database System Media Server Subsystem Text Image Video Audio Meta Data Database Server Distributed Object Search Engine API for SBS Network...
