How to make your internet work faster at home. Wi-fi or cable?

The quality of real-time video events, such as interactive music masters courses, will improve at Columbia University as a result of a new, high-speed network known as the New York Dark Fiber Network. This is just one example of the benefits of the private network for Columbia and other research, education and medical institutions in New York, which now have state-of-the-art connections to each other and to the Internet and the Internet 2.

In addition to creating faster and more reliable connections, the dark fiber network increases the efficiency and flexibility of institutions' computer networks. In Colombia, the new technology essentially doubles the capacity of its commercial internet service from 155 Mbps (megabits per second) to 300 Mbps; improves its flexibility in the future acquisition of network technology; and provides greater security of network connections in the event of critical infrastructure damage. The network is called "closed fibers" because no telecommunications operator "illuminates" it with its equipment; instead; Columbia "lights up" its fiber yarns with its own equipment, just as it does for fiber cables on nearby and nearby campuses.

The network was built in the last two years by a consortium of institutions in the area, all members of New York, based in NYSERNet, the state education and research network in New York. The Presbyterian Hospital in Columbia and New York played an important role in the project. Other founding members include the American Museum of Natural History, City University of New York, Mt. Sinai-NYU Medical Center and Weill Cornell Medical College. Additional institutions are expected to join to take advantage of the higher service, and the project has expanded to the Bronx. Finally, similar services may include other cities and Long Island.

The network has already benefited Columbia by connecting Columbia University Medical Center (CUMC) in Washington Heights and several CUMC and New York Presbyterian Hospital locations throughout Manhattan to each other and the other participating institutions, as well as the Internet dark fiber cost.

In addition, unlike telecommunications carrier services, which have costs that vary with speed, the price of fiber is fixed, while its capacity is virtually unlimited. "Owning fiber strings will allow us to choose and afford new network technologies as they grow, rather than wait and then pay someone else for better networks," said Alan Crosswell, director of the Columbia Network and Computing systems, adding that the new network allows the University to have the flexibility to implement "future fiber-based technologies that have not yet been developed."
