Towards Stateless Core: Improving SIP Proxy Scalability
White Paper This paper examines the implementation of these core IMS proxies. The Third Generation Partnership Project (3GPP) specified the IP Multimedia Subsystem (IMS) standard. This standard uses the Session Initiation Protocol (SIP) to setup and teardown... [11 Jul 2008]
Bandwidth Requirement and State Consistency in Three Multiplayer Game Architectures
White Paper This paper examines these architectures from two perspectives: bandwidth requirement at the server and players, and latency to resolve any player state inconsistencies. Multiplayer games become increasingly popular, mostly because they involve... [11 Jul 2008]
Chip Multi-Processor Scalability for Single-Threaded Applications
White Paper This paper examines the scalability potential for exploiting the parallelism in single-threaded applications on these CMP platforms. The exponential increase in uniprocessor performance has begun to slow. [11 Jul 2008]
Traffic Engineering Using MPLS for Best Effort Traffic
White Paper It examines a different and in some senses a "More complex" problem of traffic engineering in the remaining network bandwidth which is utilized by best effort traffic. By examining the best effort traffic class, this paper assumes the large volume... [11 Jul 2008]
Cache and Bandwidth Aware Matrix Multiplication on the GPU
White Paper This paper examines the use of the GPU (graphics processing unit) as a tool for scientific computing, by analyzing techniques for performing large matrix multiplies in GPU hardware. This paper examines more efficient algorithms that make the... [10 Jul 2008]
Dynamic Load Balancing for Distributed Search
White Paper This paper examines how computation can be mapped across the nodes of a distributed search system to effectively utilize available resources. It specifically address computationally intensive search of complex data, such as content-based retrieval... [10 Jul 2008]
Load Balancing for a Distributed CORBA-Based SCP
White Paper This paper examines load balancing issues relating to a distributed CORBA-based Service Control Point. Two types of load balancing strategies are explored through simulation studies. One is a novel ant-based load balancing algorithm, which has been... [10 Jul 2008]
Automatic Backdoor Analysis With a Network Intrusion Detection System and an Integrated Service Checker
White Paper This paper examines how a network intrusion detection system can be used as a trigger for service checking and reporting. This approach reduces the amount of false alerts (false positives) and raises the quality of the alert report. [10 Jul 2008]
The Advantages of Dedicated Virtual Private Network (VPN) Appliances
White Paper This white paper briefly examines several hybrid VPN configurations, including software, firewall, and router-based VPNs, and compares their suitability for certain applications with SafeNet's dedicated VPN appliance, HighAssurance 2000 Gateway. [10 Jul 2008]
On the Scalability-Performance Tradeoffs in MPLS and IP Routing
White Paper This paper investigates by simulations a range of routing solutions and examines the tradeoff between scalability and performance. MPLS (Multi-Protocol Label Switching) has recently emerged to facilitate the engineering of network traffic. [10 Jul 2008]
Managing Internal Controls: The Path to Ongoing Sarbanes-Oxley Compliance
White Paper This paper examines SOX maintenance and the role that ChannelFlex's Internal Control Management (ICM) Application plays in enabling the cost effective management of SOX. The ICM application includes a complete control model adapted from Ernst & Young. [09 Jul 2008]
Data Protection Strategies Leveraging Replication
White Paper This paper examines four data protection strategies and compares their merits for the most common business continuance scenarios including providing high availability, providing effective disaster recovery, enhancing backup and restore, and data... [09 Jul 2008]
Worth the Wait: Why SQL Server 2008 is Great
White Paper In this paper, Kevin Kline examines SQL Server 2008 and picks his top 10 capabilities and features that relate specifically to you and your job as DBA and developer. SQL Server 2008, released in the first half of 2008, is intended to provide a... [09 Jul 2008]
A Reference Architecture for Web Browsers
White Paper This paper examines the history of the web browser domain and identifies several underlying phenomena that have contributed to its evolution. Reference architecture for a domain captures the fundamental subsystems common to systems of that domain... [09 Jul 2008]
Investigation of Ethernet Switches Behavior in Presence of Contending Flows at Very High-Speed
White Paper This paper examines the interactions between high speed Ethernet switches and TCP in high bandwidth delay product networks. First, the behavior of a range of Ethernet switches when two long lived connections compete to the same output port is... [08 Jul 2008]
