WESTFORD, MA—“Triple play,” the voice, data, and video bundle that communications service
providers promote, is already yesterday’s news at Juniper Networks. Juniper engineers now
refer to “multiplay,” which adds services such as online gaming to the list of what providers can
deliver.
Regardless of how many “plays” service providers offer, video is the most demanding service
that Internet Protocol (IP) based networks must deliver. As IP video (TV and games) is
deployed, service providers need to test their network configurations. That’s where Juniper
Networks’ Westford lab plays a vital role. The lab consists of several test beds, one of which is
an entire IPTV network containing everything from video sources to TV screens. Consulting
engineer Chandra Shekhar Pandey administers this network, called the IPTV and Multiplay
Center of Excellence.
