Heuristics for Scheduling Virtual Machines for Improving QoS in Public Computing Utilities 2006-11-10 McGill University

Computing utilities based on Virtual Machines (VMs) migrating among distributed computing resources are becoming increasingly practical and emerging as a viable infrastructure for outsourcing computer services. Here, the paper presents a large scale distributed computing architecture named Public Computing Utility (PCU), where non-dedicated public resources are augmented with privately owned dedicated resources to obtain higher levels of Quality of Service (QoS) for compute intensive applications. Virtual machines are used to isolate foreign applications from the host systems and to facilitate seamless migrations. The paper has proposed several heuristics for scheduling VMs among the resources in PCU.

Building the Business Case for Application Portfolio Management 2006-11-04 01:00:15 IBM

This Forrester Report, "Building the Business Case for Application Portfolio Management," will help you build a business case for Application Portfolio Management (APM) in your enterprise.

Sponsored by IBM, the report explains why firms that use APM tools shave 10 to 30 percent or more from their maintenance budgets and achieve ROI within the first 12 months.

Enhanced Subscriber Management for Triple Play: Applying Programmable Subscriber Configuration Policies 2006-11-29 01:00:19 Alcatel

This paper explains the role and application of Programmable Subscriber Configuration Policies (PSCP) to support enhanced, scalable and unified subscriber management for triple play. PSCP harnesses the full deployment flexibility of Alcatel's Triple Play Service Delivery Architecture, and enables fully dynamic provisioning of subscriber access, Quality of Service (QoS) and security aspects, using Dynamic Host Configuration Protocol (DHCP). PSCP is an Alcatel innovation that is fully compatible with existing Remote Authentication Dial-In User Service (RADIUS) and DHCP environments, and leverages their combined strengths to give service providers a seamless migration path to an integrated and unified subscriber-management framework with superior flexibility and features.

Distributed Algorithms for Dynamic Bandwidth Provisioning in Communication Networks 2006-11-01 Academy Publisher

Efficient dynamic resource provisioning algorithms are necessary to the development and automation of Quality of Service (QoS) networks. The main goal of these algorithms is to offer services that satisfy the QoS requirements of individual users while guaranteeing at the same time an efficient utilization of network resources. This paper introduces a new service model that provides quantitative per-flow bandwidth guarantees, where users subscribe for a guaranteed rate; moreover, the network periodically individuates unused bandwidth and proposes short-term contracts where extra-bandwidth is allocated and guaranteed exclusively to users who can exploit it to transmit at a rate higher than their subscribed rate. To implement this service model the paper proposes a dynamic provisioning architecture for intra-domain Quality of Service networks.

Global Recycler Provides Reliable, Centralized Services 2006-11-01 Cisco Systems

Sims Hugo Neu Corporation is the U.S. division of The Sims Group, a global metal recycler with 160 sites. The company wanted to consolidate its separate networks, ensure application availability and reduce bandwidth costs. They also wanted a network with the Quality-of-Service (QoS) capability needed for its IP telephony, video conferencing, and ERP system. The firm selected Sprint Global MPLS Service which is a member of the Cisco Powered Network program and has received the QoS certification, indicating that it has built the service over an end-to-end Cisco infrastructure and has undergone a third-party assessment to determine that it meets Cisco best practices and standards for QoS.

IBM Tivoli Software Demo: Availability Management for the SMB 2006-10-19 01:00:15 IBM

By the time an unhappy user contacts your help desk about an availability issue or other problem, the damage to your customer satisfaction levels has already been done. That's why today's small and mid-sized businesses (SMBs) need a premier-grade infrastructure management tool. To learn about one such solution, view this Macromedia Flash demo from IBM. You'll see how IBM Tivoli software, a powerful and easy-to-use monitoring solution, helps you to:

Proactively manage infrastructure availability

Quickly diagnose and resolve bottlenecks, performance impacts,
and outages
Reduce the complexity of managing your IT environment

Monitor, analyze, correlate, and automate functions from a centralized and robust portal environment

QoS Issues With the L-Store Distributed File System 2006-10-19 Vanderbilt University

As the flood of data associated with leading edge instruments, sensors, and simulations continues to escalate, the challenge of supporting the distributed collaborations that depend on these huge flows becomes increasingly daunting. The chief obstacles to progress on this front lie less in the synchronous elements of the process, which have been reasonably well addressed by new global high performance networks, than in the asynchronous elements, where appropriate shared storage infrastructure seems to be lacking. To address this problem, the Advanced Computing Center for Research and Education (ACCRE) at Vanderbilt is developing a flexible storage framework called Logistical Storage (L-Store). L-Store is conceptually designed as a complete virtual file system.

Study of Network on Chip Resources Allocation for QoS Management 2006-10-18 Science Publications

The increasing complexity of integrated circuits and application requirements drive the research of new on-chip interconnection architectures. A network on chip draws on concepts inherited from distributed systems and computer networks subject areas to interconnect IP cores in a structured and scalable way. The main goal pursued is to achieve superior bandwidth when compared to conventional on-chip bus architectures. The complexity of Systems-on-Chip (SoC) is growing; meeting real-time requirements is becoming increasingly difficult. Predictability for computation, memory and communication components are needed to build up real-time SoC. To achieve guaranteed throughput and bounded delivery delay, buffers in Network Interfaces (NIs) must be dimensioned to hide round-trip latency and rate difference between computation and IPs communication.
