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. This proposal enables the use of hybrid Ethernet... [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). Motivated by the incommensurate complexity/cost of comparable transport... [18 Jul 2008]
Optical Burst Switching (OBS): A New Area in Optical Networking Research
White Paper This paper gives an introduction to optical burst switching (OBS) and compares it with other existing optical switching paradigms. Algorithms used at an OBS core node for burst scheduling as well as contention resolution strategies are presented next. [11 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]
Intelligent Packet Service Delivery
White Paper As core networks increasingly become enabled with optical fiber capacity, the focus of many communications providers worldwide is now turning to the access networks over which they reach their revenue sources — their subscribers. [03 Jul 2008]
FSO and Fiber: Complementary Technologies for Today’s Networks
White Paper Despite new technologies that enable legacy copper telephone lines to carry information more efficiently, optical networks remain the most ideal medium for ultra high-bandwidth communications and true connectivity. [03 Jul 2008]
The King is Dead - Recommendations for a New Monarch in the Quest for an Integrated Voice/Data Network
White Paper An optical core provides highly efficient, scalable core networking and is the goal of any migration and build out, but we must integrate current circuit switching (SONET/SDH) to be cost-effective. Providers today must figure out how to survive in... [03 Jul 2008]
3G Via Optical Core Networking
White Paper The convergence of voice, data, and video services and the close integration with the fixed networks is raising issues of network inter-working, interoperability, mobility management and the provision of dynamic and flexible bandwidth in the core... [03 Jul 2008]
Virgin Media to ramp up capacity on core network
News As web users' thirst for bandwidth soars, cable broadband purveyor Virgin Media is looking to squeeze four times the capacity out of its optical network - but without the expense of ripping out and upgrading its fibre. [09 May 2008]
Performance Evaluation of TCP Over Optical Burst-Switched (OBS) WDM Networks
White Paper Typically, an OBS network consists of optical core routers and electronic edge routers connected by WDM links. This paper studies the performance of TCP transport protocol over an optical burst-switched (OBS) wavelength division multiplexed (WDM... [14 Jan 2008]
Nortel Optical Photonic Solutions: The Adaptive, All-Optical Intelligent Network
In the process, core networks will need a significant overhauling to reliably transport this amount of information on demand. The amount of digital content around us each and every day is constantly accelerating. [09 Jan 2008]

Bill Gates Q&A: On why 'it's all about software'
Comment Obviously, all of the different optical-drive technologies are supported in Windows. I think the core of who we are and what we do [is] believing in a platform. At the core, we are about software and making sure the HD activities get to critical mass. [08 Jan 2008]
The Impact of Burst Switching on TCP Performance
Optical Burst Switching (OBS) has brought a new switching paradigm for transparent all optical networks by getting rid of buffers at core nodes. Main features of OBS are burst assembly and delayed reservation. [06 Dec 2007]
