The Core Optical Networks (CORONET) program addresses the development of architectures, protocols, and network control and management to support the future advanced requirements of both commercial and government networks, with a focus on highly dynamic and highly resilient multi-terabit core networks. CORONET encompasses a global network supporting a(More)
—Over the past 25 years, networks have evolved from being relatively static with fairly homogeneous traffic to being more configurable and carrying a heterogeneous array of services. As the applications are ultimately the driver of network evolution , the paper begins with a brief history of circuit, packet, and wave services, along with the development of(More)
At current growth rates, Internet traffic will increase by a factor of one thousand in roughly 20 years. It will be challenging for transmission and routing/switching systems to keep pace with this level of growth without requiring prohibitively large increases in network cost and power consumption. We present a high-level vision for addressing these(More)
We present a logical approach to designing an effective and efficient error detection scheme for ATM. We specifically look at providing error protection for the class C service of ATM, which is a connection oriented, variable bit rate service, with no required timing between source and destination. Our resulting scheme is similar to the scheme proposed by(More)
— While all-optical networking had its origins in the research community a quarter of a century ago, the realization of the vision has not had a straight trajectory. The original goal of the all-optical network was based on keeping the data signals entirely in the optical domain from source to destination to eliminate the so-called electronic bottleneck,(More)
The focus of this paper is the perspectives of people, both employers and employees, who are engaged in lifelong e-learning, within the UK economy. It puts forward two models of lifelong e-learning. One of which reflects employees' approaches to their own e-learning and self development, the employee model. The other model reflects the motivations of(More)
