DENVER, 10/6/2017 – Jim Sabey, head of connect and compute sales specialists at BT Americas, talks with Light Reading's Carol Wilson about how virtualization has changed the telco's relationships with its vendors during this video from Light Reading's NFV and Carrier SDN event in Denver. Instead of the traditional siloed approach where each manufacturer had its own piece of hardware on the network, BT is now requiring vendors to share their software applications -- such as virtual routers and virtual firewalls -- on a single x86 server or box.
