RSS circuitEffects of Corner Frequency on Bandwidth and Resonance Amplitude in Designing PZT Thin-Film Actuators
White Paper As an electromechanical device, a PZT thin-film actuator's bandwidth and resonance amplitude depend not only on the lowest natural frequency un of the actuator's mechanical structure but also on the corner frequency uc of the actuator's RC-circuit. [11 Jul 2008]
Datanet UK Case Study: ABSL Power Solutions
White Paper As a large, multi-site company wishing to have a highly robust, secure and dedicated line for their sites, the ideal solution was an MPLS (Multi Protocol Label Switching) circuit. ABSL Power Solutions existing WAN connections were no longer meeting... [11 Jul 2008]
A Reconfigurable Ethernet/SONET Circuit-Based Metro Network Architecture
White Paper Primary among these is that it allows a metro optical circuit-switched network to be operated at a high utilization, which is important to achieve a cost-effective bandwidth-efficient network. This paper proposes a service concept in which high... [10 Jul 2008]
Optical-Label Switching, MPLS, MPLambdaS, and GMPLS

Modeling GMPLS Domains in MPLS Networks
White Paper This paper describes how optical circuit switched, GMPLS-based networks can be incorporated in such multi-domain, MPLS-based scenarios and how it could be modeled with the OPNET MPLS model. A consequence of migrating the existing Internet... [10 Jul 2008]
Performance and Implementation of Dynamic Frequency Hopping in Limited-Bandwidth Cellular Systems
White Paper Voice-only circuit-switched operation is assumed. This paper evaluates the performance of recently proposed Dynamic Frequency Hopping (DFH) when applied to cellular systems with a limited total bandwidth. [10 Jul 2008]
Preserving End-to-End Quality of Service for IP VPNs Over MPLS Satellite Networks
White Paper Enterprise users increasingly look to MPLS providers for services to replace traditional leased lines and as less ex-pensive alternatives to virtual circuit services, mostly Frame Relay and ATM. The entire telecommunications industry has expressed... [10 Jul 2008]
Voice Trunking and Toll-Bypass Trunking Using Cisco MPLS DiffServ-Aware Traffic Engineering
White Paper Service providers need to integrate their packet- and circuit-switched infrastructures to save costs and offer data and voice services. Trunking voice traffic using a data infrastructure is less expensive than using dedicated circuit-switched... [09 Jul 2008]
Mitigating Attacks in VoIP Environments
White Paper Service providers are deploying packet telephony technologies as an alternative to traditional circuit-switched telephone networks in order to shift traditional voice services to packet-based networks and to create new services that combine data... [09 Jul 2008]
A Flexible Solution for Industrial Ethernet

Challenges and Opportunities for Transport Providers & Mobile Operators
White Paper They can buy TDM services from the transport providers, but then they need Ethernet bridging and circuit bonding for emerging services; or, they can buy Ethernet services, but then they must verify their SLAs and utilize pseudowire technology for... [04 Jul 2008]
Integrating Ethernet in Carrier Class Networks
White Paper A variety of circuit-oriented constraints such as oversubscription and committed/peak transmission rates - traditionally associated with WAN technologies such as ATM and frame relay - have also emerged as Ethernet requirements. [04 Jul 2008]
Near-Optimal Delay Constrained Routing in Virtual Circuit Networks
White Paper In this paper, we consider the problem of minimizing the average cross-network packet delay in virtual circuit networks subject to an end-to-end delay constraint for each origin-destination user pair. [03 Jul 2008]
