Impacts of TCP on High Bandwidth Digital Video Stream
White Paper This paper is about the impact of other flows on the high bandwidth digital video application. Many high bandwidth digital video applications have used UDP as transport layer protocol, and been considered as unresponsive flows. [11 Jul 2008]
Securing Layer 2 in Local Area Networks
White Paper Network security problems have been well known and addressed in the application, transport, or network layers. However, the Data Link Layer (Layer 2) security has not been adequately addressed yet. To secure Local or Metropolitan Area Networks, the... [11 Jul 2008]
Load Balancing on Open Networks: A Mobile Agent Approach
White Paper In order to disperse the load on a Web server, generally the server cluster is configured to distribute access requests, or mirror servers are distributed geographically on different networks. Use of the Internet and the World-Wide-Web (WWW) has... [11 Jul 2008]
Minimum Failure Explanations for Path Vector Routing Changes
White Paper Path vector protocols in routing networks convey entire path information to each destination. When links fail, affected paths are replaced by new paths, and by observing the entire path information, one might hope to infer the failed links that... [11 Jul 2008]
A Rate Control Scheme for H.264 Video Under Low Bandwidth Channel
White Paper The dilemma of the Quantization Parameter (QP) being involved in both rate control and Rate-Distortion Optimization (RDO) prevents using the traditional rate control scheme. Although some rate control schemes are proposed to circumvent the dilemma... [11 Jul 2008]
Advanced Design Methods of Doherty Amplifier for Wide Bandwidth, High Efficiency Base Station Power Amplifiers
White Paper This paper has proposed advanced design methods of Doherty amplifier for high efficiency base station power amplifiers with wide bandwidth. First, the paper develops Doherty amplifier with uneven power drive which is provided more input power to... [11 Jul 2008]
A Class-Based Dynamic Bandwidth Allocation Scheme for EPONs
White Paper In an Ethernet Passive Optical Network (EPON), all Optical Network Units (ONUs) share one uplink channel to transmit multiple traffic. To avoid data collision, a contention-free MAC protocol is needed to schedule the transmission order of different... [11 Jul 2008]
White Paper: Tips for Writing Good Use Cases
White Paper Writing good use cases is more of an art than a science. In this IBM Rational white paper "Tips for writing good use cases," IBM requirements evangelist Jim Heumann explores the history and function of the use case, then provides a set of tips to... [10 Jul 2008]
Object-Based Adaptive Load Balancing for MPI Programs
White Paper Parallel Computational Science and Engineering (CSE) applications often exhibit irregular structure and dynamic load patterns. Many such applications have been developed using procedural languages (e.g. [10 Jul 2008]
Adaptive Load Balancing for MPI Programs
White Paper Parallel Computational Science and Engineering (CSE) applications often exhibit irregular structure and dynamic load patterns. Many such applications have been developed using MPI. Incorporating dynamic load balancing techniques at the application... [10 Jul 2008]
Load Balancing Strategies for Parallel SAMR Algorithms
White Paper Highly resolved numerical solutions of partial differential equations are important in many areas of science and technology. Only adaptive mesh refinement methods reduce the necessary work sufficiently, allowing the calculation of realistic problems. [10 Jul 2008]
A Dynamic Load Balancing in Wireless CDMA Cellular Networks
White Paper With the increase of cellular users the traffic hot spots and unbalanced call distributions are common in wireless networks. The CDMA techniques enables a base tranciever station to connect microcells with optical fibers and to control the channels... [10 Jul 2008]
Improving Performance of a Dynamic Load Balancing System by Using Number of Effective Tasks
White Paper Efficient resource usage is a key to achieving better performance in cluster systems. Previously, most research in this area has focused on balancing the load of each node to use the resources of an entire system more effectively. [10 Jul 2008]
Dynamic Load Balancing Strategy for Grid Computing
White Paper Workload and resource management are two essential functions provided at the service level of the grid software infrastructure. To improve the global throughput of these software environments, workloads have to be evenly scheduled among the... [10 Jul 2008]
A Wireless Secure Remote Access Architecture Implementing Role Based Access Control: WiSeR
White Paper This paper proposes network architecture for providing secure access to information resources of enterprise network from remote locations in a wireless fashion. This proposed architecture offers a very promising solution for organizations which are... [10 Jul 2008]
