A Fast and Scalable Inter-Domain MPLS Protection Mechanism
White Paper With the fast growth of Internet and a new widespread interest in optical networks, the unparalleled potential of Multi-Protocol Label Switching (MPLS) is leading to further research and development efforts. [04 Aug 2008]
Preconfiguring IP-Over-Optical Networks to Handle Router Failures and Unpredictable Traffic
White Paper In implementing this scheme, the first and second phase paths are realized at the optical layer with router packet grooming at a single intermediate node only. This paper considers the realization of traffic-oblivious routing in IP-over-Optical... [18 Jul 2008]
Multimedia Polska SA (Poland) Choose Allied Telesis for Triple Play
White Paper After evaluating a number of vendors, Multimedia selected two products from Allied Telesis - the AT-9924T, a 24 copper port Gigabit Layer 3 switch, and the AT-9924SP switch, an SFP port version that is compatible with a wide range of optical modules. [18 Jul 2008]
Optical Switching: Switch Fabrics, Techniques, and Architectures
White Paper All-optical switch fabrics play a central role in the effort to migrate the switching functions to the optical layer. Optical packet switching provides an almost arbitrary fine granularity but faces significant challenges in the processing and... [18 Jul 2008]
WDM and SDM in Future Optical Networks
White Paper It is prompted by the fact that both SDM and WDM are viable options for the optical layer of all-optical networks. To meet these demands, optical techniques are being introduced in public networks but on a link-to-link basis. [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]
Multi-Objective Optimization of Bandwidth Broker With Evolutionary Algorithm
White Paper The bandwidth allocation and reconfiguration of topology in Optical Transport Networks (OTN) with DWDM and lambda switching is a process of rearranging a virtual topology to meet traffic demands that change over a period of time. [11 Jul 2008]
RF Bandwidth Capacity and SCM in a Radio-Over-Fibre Link Employing Optical Frequency Multiplication
White Paper Since these standards specify the radio interface access and physical layer in single cells, a dedicated access architecture to fixed networks, like the ones defined in mobile cellular networks, is missing, and the integration of the spots into... [11 Jul 2008]
Bidirectional Optical Ring Network Having Enhanced Load Balancing and Protection
White Paper Massive growth of the Internet traffic in last decades motivated the design of high-speed optical network for traffic aggregation from different access technologies. OTDM technology is used for statistical traffic multiplexing while reservation... [10 Jul 2008]
Dynamic LSP Provisioning in Overlay, Augmented, and Peer Architectures for IP/MPLS Over WDM Networks
White Paper This paper considers an IP/MPLS over WDM network, in which Label Switched Routers (LSRs) in the IP/MPLS layer are interconnected through Optical cross-Connects (OXCs) in the optical core network (WDM layer) providing an end-to-end wavelength... [10 Jul 2008]
Protected Ethernet Rings for Optical Access Networks
White Paper This paper proposes a centralized link layer architecture for providing low latency fault recovery for optical access rings. Consequently, when compared with a standardized Rapid Spanning Tree Protocol implementation, the design of the proposed... [08 Jul 2008]
An Experiment of Controlling Gigabit Wide Area Ethernet by GMPLS Supporting Layer-2 Switching Capability
White Paper High speed and large capacity Ethernet technologies have been developed as represented by Gigabit Ethernet (GE) and 10 Gigabit Ethernet (10GE). Currently, due to the growth of Ethernet technologies, Ethernet has been deployed in Wide Area Network... [04 Jul 2008]
Business Impact of Transparent Optical Switching
White Paper At the optical layer, WDM offers enormous bandwidth and increasingly sophisticated reconfiguration capabilities. As capabilities grow rapidly in both technologies, it becomes appealing to bypass intermediate-layer technologies such as SONET/SDH and... [03 Jul 2008]
Optical Wireless Systems and Network Security
White Paper LightPointe's optical wireless networking equipment is based on physical layer transport. Such network security concerns involve the lowest network layer, typically referred to as the physical layer (layer one), as well as higher software layers of... [03 Jul 2008]
