Metro Ethernet has been widely adopted lately. One of its goals is to provide clients with VPN services, and in this context, loadbalancing and protection have become important issues. This paper presents an original formulation of these problems in Metro Ethernet, and introduces an algorithm for load balancing which provides good numerical results.

As current sustained traffic growth is expected to strain capacity of today’s metro network, novel content distribution architectures where contents are placed closer to the users are being investigated. In that regard, telecom operators can deploy datacenters (DCs) in metro areas, thus reducing the impact of the traffic going from users to DCs. However, effective solutions to distribute conten...

To study the impact of information dissemination on public's risk perception in metro emergencies, we carried out an empirical study among Shanghai Metro passengers. Though an investigation of passengers’ response to the frequency, type and channel of information dissemination, we developed a Logit model measuring public response for future manipulation.

The development of metro infrastructure projects (MIP) has been playing an important role in the economic growth in China through improving urban transportation condition. The economic benefits from MIP in China have been well appreciated.

Most successful crime prevention efforts take the approach of "designing out crime" through the identification of highly specific crime problems and the development of preventive efforts to reduce them (Clarke, 1992). A study of the design, maintenance and management of "Metro," Washington, DCs subway system, allows for the novel approach of evaluating an effort to design in security at the out...

Nowadays, the majority of construction projects can be considered as complex and ambiguous endeavours. Each kind of construction project has its own characteristics and complexities whereas then specific management approaches and solutions are needed. Regarding the rapid development of cities, underground constructions at urban regions, such as metro construction, have been largely used for ext...
