The Internet revolution. Once, the public was delighted with 14.4 modem access and
fascinated by low-tech Web site content. But not for long. Technology has raced to keep up …

We consider the problem of designing a network of optical cross-connects (OXCs) to provide
end-to-end lightpath services to large numbers of label switched routers (LSRs). We present …

In this paper, we investigate the problem of quality-of-service (QoS) multicast routing for
multimedia group communications. We first develop a unified framework for achieving QoS …

Virtualization of optical networks is key enabler of cloud computing. A main part of optical
network virtualization is virtual network mapping on the physical infrastructure. One major …

给定组播请求与用户QoS 需求, 提出的算法基于遗传算法GA 来构造一棵柔性QoS 组播树 …

The continuous growth of broadband communications, multimedia services and Internet is
absolutely related to the deployment and operation of optical networks. Despite optical …

In this paper, we consider the problem of designing virtual topologies for multihop optical
WDM networks when the traffic is self-similar in nature. Studies over the last few years …

Over the past few decades the use of telecommunication services has been growing
dramatically, and many new and advanced services will be brought to the market in the …

Lifeline systems, such as water distribution and gas supply networks, usually cover large
areas. For these systems, seismic design is always a difficult problem because of the …

Optical networks based on WDM technology are potential candidates for future networks.
The design of virtual topology using routing and wavelength assignment algorithms is the …
