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]
Light Trails: A Sub-Wavelength Solution for Optical Networking
White Paper All-optical networks are able to transport data from source to destination entirely in the optical domain. MPLS, OBS and OPS have been proposed as solutions to realizing an all-optical network. This is a departure from current optical networks that... [18 Jul 2008]
Effectiveness of Shared Risk Link Group Auto-Discovery in Optical Networks
White Paper This paper evaluates location-based methods for the auto-discovery of SRLGs, guided by the topology and design of AT&T's next generation transport network. Shared Risk Link Groups (SRLGs), introduced in, provide inputs necessary to plan for... [18 Jul 2008]
Shared Protection Routing Algorithm for Optical Network
White Paper In a connection-oriented network such as an all-optical transport network, shared protection provides the same level of protection against single path failures as dedicated protection, with potentially higher network utilization. [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 â-channels (lightpaths) of a fixed capacity are the main mechanism of transport. In other words, the authors believe that it is... [11 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]
QoS Recovery Schemes Based on Differentiated MPLS Services in All-Optical Transport Next Generation Internet
White Paper Given this increasing demand for high bandwidth Internet with QoS assurances in the coming years, an IP/MPLS-based control plane combined with a wavelength-routed Dense Wavelength Division Multiplexing (DWDM) optical network is seen as a very... [10 Jul 2008]
Efficient Network Switching Hierarchy
White Paper In this paper, it is argued that the right granularity for grooming in the next-generation core optical network is STS-48 (2.5 Gbps), while STS-1 (51.8 Mbps) grooming is better suited for the edge of the network and legacy applications. [10 Jul 2008]
A Reconfigurable Ethernet/SONET Circuit-Based Metro Network Architecture
White Paper This paper proposes a service concept in which high-speed Ethernet interfaces from end hosts are dynamically cross-connected to equivalent-rate Ethernet-over-SONET (EoS) optical circuits for transport across metro-area networks and/or wide-area... [10 Jul 2008]
An Experiment of Controlling Gigabit Wide Area Ethernet by GMPLS Supporting Layer-2 Switching Capability
White Paper Therefore Wide Area Ethernet is focused on as a high performance transport network. Currently, due to the growth of Ethernet technologies, Ethernet has been deployed in Wide Area Network (WAN) as well as Local Area Network (LAN). [04 Jul 2008]
Optical Transport Network: Solution to Network Scalability and Manageability
White Paper Synchronous Optical NETwork (SONET)/Synchronous Digital Hierarchy (SDH)has been the major underlying technology for today’s transport networks. With the ever-growing internet and other data-oriented traffic usage,a new scheme of network was needed... [03 Jul 2008]
Borland VisiBroker-RT Adds Flexible Network Management to High-Performance Optical Transport Platform
White Paper Cisco Systems created an immediate sensation in 1998 when it released the Cisco ONS 15454 Optical Transport Platform. The Cisco ONS 15454 provides service providers with outstanding capabilities in the areas of scalability and flexibility at a low... [03 Jul 2008]
Taiwan's New National Research Network Chooses Cisco Optical Solution
White Paper The four network nodes are supported by Cisco ONS 15600 Multiservice Switching Platforms (MSSP) and Cisco ONS 15454 Multiservice Transport Platforms (MSTP) that provide enhanced SDH capabilities and can also support intelligent dense wavelength... [03 Jul 2008]
NTS Testing Labs: SONET (Synchronous Optical Network) GR-253/GR-1377 Test Lab Compatibility & Functionality Test Outline
White Paper Test procedures are designed to verify compliance and conformance of a client’s product (Equipment Under Test) with Synchronous Optical Network (SONET) specifications and requirements, generally outlined herein and defined in Bellcore General... [03 Jul 2008]
Optical Networks for Mobile Backbone and Access: a Flexible, Evolutionary Approach
White Paper Optical transport networking is about to play a significant role in the building of the network infrastructure for third generation (3G) mobile networks. There is much talk about all-IP and all optical networking: to many people these appear to be... [03 Jul 2008]
