Humble ISD's Centralized, Clustered Network Infrastructure Is Improving the Quality of Education Through 20-Fold Faster Data Access, Greater Uptime, More Reliable Data Backup and a 40% Reduction in IT Administration Time 2008-03-01 Dell

The Humble Independent School District is named for a pioneering Texas settler, not for its approach to education. The fast-growing Humble Independent School District needed to improve network bandwidth and uptime, make data backup faster and more reliable, and reduce the time its IT staff spent on repairs and routine maintenance. Dell Services helped Humble ISD implement a highly robust, scalable server cluster, based on Dell PowerEdge servers. The cluster consolidates e-mail, office software and educational tools from 40 separate servers and offers dramatically faster access and simplified maintenance. The district turned its old data center into a mirrored disaster recovery site using Dell and EMC technology.

Microsoft Dynamics CRM 4.0: Performance and Scalability - Bandwidth Utilization Improvements 2008-03-01 Microsoft

Microsoft Dynamics CRM business software is designed to help enterprise organizations achieve a 360-degree view of their customers across marketing, sales, and service. Engineered to deliver performance that meets the needs of the largest global deployments, Microsoft Dynamics CRM has been tested for user scalability, data scalability, and network performance. This white paper focuses on network scalability improvements.

Microsoft has made significant enhancements to the architecture of Microsoft Dynamics CRM 4.0 to improve network performance. Test results demonstrate network bandwidth utilization improvements of up to 94%. Improvements were evaluated in the number of round trips, bytes sent, and bytes received. Because the bandwidth utilization associated with a page can change after the first time the page is loaded, both initial (cold) and subsequent (warm) page loads were tested.

Bandwidth Constrained IP Multicast Traffic Engineering Without MPLS Overlay 2008-01-01 University of Surrey

Existing multicast Traffic Engineering (TE) solutions tend to use explicit routing through MPLS tunnels. This paper shifts away from this overlay approach and address the bandwidth constrained IP multicast TE directly based on link state IGP routing protocols. The objective is that, through plain PIM-SM shortest path routing with optimized Multi-topology IS-IS (MISIS) link weights, the resulting multicast trees are geared towards minimal consumption of bandwidth resources. The paper applies Genetic Algorithms (GA) to the calculation of optimized M-ISIS link weights that specifically cater for engineered PIM-SM routing with bandwidth guarantees.

Chulalongkorn University Deploys Cisco Service Control Engine to Optimize Bandwidth Usage for Researchers, Students and Staff 2007-10-25 Cisco Systems

Chulalongkorn has been an early adopter of networking and Internet technologies, but the popularity of Peer-to-Peer (P2P) networking applications was beginning to consume a disproportionate amount of campus bandwidth, as well as posing security risks to the network. Affirming its vision to take advantage of Information and Communications (ICT) Technology, Chulalongkorn University has put in place a service control solution from Cisco to optimize bandwidth usage and prioritize network traffic for researchers, students and staff. The new solution allows researchers to efficiently use the Internet and Chulalongkorn's own network, which is also built with Cisco equipment, to collaborate with their colleagues in other institutions, while ensuring sufficient bandwidth on the network for students to communicate with their lecturers and peers and to access academic resources.

Dealing With Sudden Bandwidth Changes in TCP 2007-09-29 Korea Advanced Institute of Science and Technology

This paper proposes a novel technique to deal with sudden bandwidth changes in TCP. In the current Internet, sudden bandwidth changes may occur due to vertical handovers between heterogeneous access networks or routing path changes. The current implementation of TCP is designed and optimized for stable networks, and does not adapt well upon sudden bandwidth changes. Consequently, it might suffer from packet losses in burst upon sudden decrements of bandwidth and under-utilization upon sudden increments of bandwidth. To resolve this problem, the paper proposes to modify the current TCP algorithm to include a new phase, called Fast Adaptation (FA).

Smaller File Format Saves Service Company 300-Plus Hours Per Week on Data Backups 0000-00-00 Microsoft

Hobart Service delivers, installs, and maintains equipment for the foodservice and food retail industries. With nearly 1,400 employees working from 97 locations across the United States, Hobart needed a more efficient way to transmit, store, and back up user data on the company's central server computers. When the IT department saw how much server space and bandwidth it could save by taking advantage of the smaller file formats used in the 2007 Microsoft Office release, the company decided to upgrade its desktops to Microsoft Office Professional Plus 2007.

A Strategy to Manage Cache Consistency in a Distributed Mobile Wireless Environment 0000-00-00 Colorado State University

Mobile computing environments are characterized by slow wireless links and relatively underprivileged hosts with limited battery powers, predisposed to frequent disconnections. Caching data at the Mobile Hosts (MHs) in a wireless network helps alleviate problems associated with slow, limited bandwidth wireless links, by reducing latency and conserving bandwidth. Battery power is conserved by reducing the number of up-link requests. A mobile computing environment is a distributed system, thus when data at the server changes, the client hosts must be made aware of this fact in order for them to invalidate their cache otherwise the host would continue to answer queries with the cached values returning incorrect data.

MobiNet: A Scalable Emulation Infrastructure for Ad Hoc and Wireless Networks 0000-00-00 Duke University

The current state of the art in evaluating applications and communication protocols for ad hoc wireless networks usually involves either simulation or small-scale live deployment. Larger-scale live deployment is typically costly and difficult to run under controlled circumstances. Simulation allows more flexibility in varying system configurations, but requires the duplication of application and network behavior within the simulator. While simulation and live deployment will clearly continue to play important roles in the evaluation of mobile systems, the paper presents MobiNet, a third point in this space.

Establishing a Trade-Off Between Unicast and Multicast Retransmission Modes for Reliable Multicast Protocols 0000-00-00 Universidade Federal de Pernambuco

The conventional approach to reliable multicast in computer networks relies on the retransmission on demand of lost packets. Existing multicast protocols adopt a static packet retransmission scheme (unicast or multicast) to retransmit these packets, often leading to performance loss due to wasting bandwidth resources. This is worse if it consider the limited bandwidth resources wireless interfaces currently offer. Therefore, careful continuous monitoring and control is fundamental in these wireless mobile environments. This paper looks at solutions to the retransmission problem while taking into consideration network topology and the number of fixed and mobile users. Precise conditions and rules for packet retransmission are set taking into account the dynamics of the network state.
