Virtualizing Storage for VMware Success
White Paper Storage infrastructure and operational practices that were designed for physical server architectures are not well suited to meet the demands of a virtual infrastructure. Server virtualization has made day-to-day life a whole lot simpler for... [24 Jul 2008]
A Review of Traffic Grooming in WDM Optical Networks: Architectures and Challenges
White Paper Various network and node architectures for different traffic-grooming scenarios are compared and discussed. The transmission capacity of a link in today's optical networks has increased significantly due to Wavelength-Division Multiplexing (WDM... [18 Jul 2008]
Middleware and Management Support for Programmable QoS-Network Architectures
White Paper In particular, the paper describes a middleware for programmable Differentiated Service (DiffServ) architectures. DiffServ architectures are envisaged by the standardization body of the IETF to be open to an evolutionary process and to facilitate... [18 Jul 2008]
On the Throughput-Cost Tradeoff of Multi-Tiered Optical Network Architectures
White Paper This paper conducts a throughput-cost study of several optical network architectures: Optical Flow Switching (OFS), Tell-and-Go (TaG), Electronic Packet Switching (EPS), and Generalized MultiProtocol Label Switching (GMPLS). [18 Jul 2008]
On the Capacity of Optical Networks: A Framework for Comparing Different Transport Architectures
White Paper This paper compares three optical transport network architectures: Optical Packet Switching (OPS), Optical Flow Switching (OFS), and Optical Burst Switching (OBS). It characterizes the capacity regions of the transport architectures, and show that... [18 Jul 2008]
Optical Switching: Switch Fabrics, Techniques, and Architectures
White Paper The switching speeds of electronics cannot keep up with the transmission capacity offered by optics. All-optical switch fabrics play a central role in the effort to migrate the switching functions to the optical layer. [18 Jul 2008]
End-to-End QoS Control Architectures From a Wholesale and Retail Perspective: Benefits and Challenges
White Paper Providing an equal or better grade of service compared to legacy networks is essential for an NGN operator as insufficient service quality severely reduces the value of the network. Also, cost-effectiveness and rapid service deployment are two... [18 Jul 2008]
Study of Network on Chip Resources Allocation for QoS Management
White Paper The increasing complexity of integrated circuits and application requirements drive the research of new on-chip interconnection architectures. The main goal pursued is to achieve superior bandwidth when compared to conventional on-chip bus... [18 Jul 2008]
A Comparison Between IPsec and Multiprotocol Label Switching Virtual Private Networks
White Paper Two unique and complementary VPN architectures based on IP security (IPsec) and MultiProtocol Label Switching (MPLS) technologies are emerging to form the predominant foundations for delivery of New World services. [18 Jul 2008]
A QoS-Aware Selection Model for Semantic Web Services
White Paper Automating Service Oriented Architectures by augmenting them with semantics will form the basis of the next generation of computing. Selection of service still is an important challenge, especially, when a set of services fulfilling user's... [18 Jul 2008]
IP Over All-Optical Networks - Issues
White Paper IP over Optical is being envisioned as one of the most attractive architectures for the new Internet. There have been various proposals in IETF and other international standards organizations regarding the interaction of IP routers and Optical core... [18 Jul 2008]
10 Gbps NRZ-DPSK Modulation in SOA-Based Optical Packet Switching Networks
White Paper In most OPS network architectures, Semiconductor Optical Amplifiers (SOA) are the predominant technology used in switching elements due to their fast switching time, broad gain bandwidth and potential for hybrid integration with optical and... [18 Jul 2008]
The Meta-QoS-Class Concept: A Step Towards Global QoS Inter-Domain Services
White Paper Indeed, several architectures have been designed in order to introduce QoS that violate the fundamental features of the best-effort Internet. IP QoS (Quality of Service) is commonly presented as a radical shift in the IP paradigm and therefore, in... [18 Jul 2008]
Bluetooth Device Manager Connecting a Large Number of Devices With Different QoS Requirements in a Bluetooth Network
White Paper A reason why Bluetooth is even considered for a Service Oriented Architectures (SOAs) network consisting of a large number of resource-constraint devices. The unique advantages of Bluetooth such as low power consumption capability, cheap hardware... [18 Jul 2008]
QoS in Mobile Multimedia Networks
White Paper This paper develops an abstract framework for different architectures of network layer mobility support like Mobile IP, Cellular IP, IPv6, GSM, UMTS etc.and discusses their appropriateness for QoS handling. [18 Jul 2008]
