Voice over Internet Protocol (VoIP) refers to a family of hardware and software technologies that deliver voice communications over the internet rather than the public, switched telephone network. To make it work, technologists have to convert traditional analog signals into a digital format and then translate that signal into IP packets for transmission over a private or public network.
At the October 28 Lunch ‘n Learn, Dave Wirth, Manager of Operations within the Office of Information Technology’s (OIT) Networking/Telephony group, reviewed the technology, its present implementation at Princeton, and the University’s plans for the future.
The new Peter B. Lewis Library contains a new OIT-operated Broadcast Center with a high definition video studio that features a green room with a 65 inch LCD screen, a professional audio recording studio, as well as the hardware and software to edit video, color correct footage, and sweeten and edit audio. The Studio also has a Broadcast van with full, mobile production capabilities.
The Broadcast Studio staff is happy to assist members of the University community from the beginning through the end of their A/V projects, from the actual shoots through video editing and the final distribution. Some of the projects involve location shoots (from single camera shoots through full production), live event productions (such as Commencement and Opening Exercises), and in-studio shoots that aid in control of lighting and other key conditions. The Center also manages lecture recordings (including he integration of lecture A/V and speaker slides), podcasts, and rich media content.
At the March 7 Lunch ‘n Learn, OIT’s Senior Manager of Networking, Peter Olenick presented Campus Networking and the Internet: How They Work.
“Most people really don’t care how networking works… they simply care that it does work,” summarized Olenick.
During his hour session, Olenick reviewed the technologies involved in campus and internet networking with some focus upon how that technology is actually used on campus and why this complex environment sometimes does not operate as users expect it to.
This image of a network pipe illustrates some of the complexity. There are electronics, logical components, there are network services, and then there are the actual applications that run on top… together, they make up what most users think of as their network connection. All aspects must work in order to provide useful service.
