Data Technologies in 3G Access Networks: Meeting the Demand for New Mobile Services
White Paper For most mobile operators this means moving away from running packet-switched services over Time Division Multiplexing (TDM) networks, and running data over an efficient and cost effective data-focused infrastructure. [28 Jul 2008]
Early Drop and Wavelength Grouping Schemes for Providing Absolute QoS Differentiation in Optical Burst-Switched Networks
White Paper A number of schemes have been proposed to support QoS in Optical Burst-Switched (OBS) networks. Most schemes only support relative QoS differentiation instead of absolute QoS guarantee. However, absolute QoS differentiation is a basic requirement... [18 Jul 2008]
Utilizing Path Diversity in Optical Packet Switched Interconnection Networks
White Paper SPINet (Scalable Photonic Integrated Network) was recently introduced as an optical packet switched interconnection architecture for local area applications such as high-performance computing systems and storage-area networks. [18 Jul 2008]
Threshold-Based Burst Assembly Policies for QoS Support in Optical Burst-Switched Networks
White Paper This paper proposes a threshold-based burst assembly scheme in conjunction with a burst segmentation policy to provide QoS in Optical Burst Switched (OBS) networks. Bursts are assembled at the network edge by collecting packets that have the same... [18 Jul 2008]
Dynamic Injection Control Module for Optical Packet Switching Fabrics
White Paper Optical Packet Switched (OPS) networks offer the unique combination of encompassing the enormous capacity of the optical domain while providing versatile connectivity afforded by individual packet routing. [18 Jul 2008]
Preconfiguring IP-Over-Optical Networks to Handle Router Failures and Unpredictable Traffic
White Paper This paper considers the realization of traffic-oblivious routing in IP-over-Optical networks where routers are interconnected over a switched optical backbone. The traffic-oblivious routing the paper considers is a scheme where incoming traffic is... [18 Jul 2008]
Bufferless All-Optical Networking With Erasure Codes
White Paper An idea for enabling all-optical packet switched networks is to use deflection routing together with erasure recovery coding at the packet level. Deflection routing has been generally considered in the past only in highly structured networks. [18 Jul 2008]
10 Gbps NRZ-DPSK Modulation in SOA-Based Optical Packet Switching Networks
White Paper Optical Packet Switched (OPS) networks are a promising means of delivering high bandwidth data communication with the fine granularity enabled by individual packet routing. In most OPS network architectures, Semiconductor Optical Amplifiers (SOA... [18 Jul 2008]
Using Dynamic Optical Networking for High-Speed Access
White Paper Through the use of switched optical circuits the number of hosts that can be supported on a metropolitan area core ring network can be increased significantly at an acceptable grade of service. While LAN and wide-area network link capacities keep... [18 Jul 2008]
Quality of Service in Internet Protocol (IP) Networks
White Paper Termed converged networking, these new IP technologies allow enterprises to convert from separate circuit-switched telephone and ISDN video networks to all IP networks where data, voice, and video all traverse the same network infrastructure. [17 Jul 2008]
Is Your Network Ready for VoIP?
White Paper As vendors and customers begin to implement strategies to move from a traditional TDM-based circuit-switched PBX to a converged IP voice and data network, an increasing number of enterprise organizations are trying to understand how their existing... [15 Jul 2008]
Comparison of Available Bandwidth Estimation Techniques in Packet-Switched Mobile Networks
White Paper The relative contribution of the transport network towards the per-user capacity in mobile telecommunication systems is becoming very important due to the ever increasing air-interface data rates. Thus, resource management procedures such as... [11 Jul 2008]
An Algorithm for Rerouting in Traffic Engineering of MPLS Based IP Networks
White Paper Rerouting and bumping of Label Switched Paths (LSP) are caused by link or node failure or recovery, connection admission or load balancing. MultiProtocol Label Switching (MPLS) enables IP networks with Quality of Service to be traffic engineered well. [11 Jul 2008]
Optimal Granularity of MPLS Tunnels
White Paper This paper considers the problem of tunneling MPLS Label Switched Paths (LSPs) over an optical network in which รข-channels (lightpaths) of a fixed capacity are the main mechanism of transport. While any set of LSPs, each LSP having an arbitrary... [11 Jul 2008]
Network Protection Design for MPLS Networks
White Paper This paper considers the problem of designing partially and fully survivable explicit label switched paths for MPLS networks. These problems are model as Mixed Integer Linear Programs. Furthermore, it presents a survivability assessment of the models. [11 Jul 2008]
