Juniper engineers nowrefer to “multiplay,” which adds services such as online gaming to the list of what providers candeliver.Regardless of how many “plays” service providers offer, video is the most demanding servicethat Internet Protocol (IP) based networks must deliver. As IP video (TV and games) isdeployed, service providers need to test their network configurations. That’s where JuniperNetworks’ Westford lab plays a vital role. The lab consists of several test beds, one of which isan entire IPTV network containing everything from video sources to TV screens. Consultingengineer Chandra Shekhar Pandey administers this network, called the IPTV and MultiplayCenter of Excellence.
