in granular one-minute increments. Most importantly, the newer, more complex network needed to preserve the simple, customer controlled service model. Since most of the video transport services The Switch offers are of uncompressed nature (1.5 Gbps HD-SDI or 270 Mbps SD-SDI), the connectivity between cities needed to have high bandwidth. In the metro, star-topology network, bandwidth was not a problem; connectivity consisted of the video router backplane inside The Switch facility. The high intercity bandwidth demands of the new network mandated a transmission platform that could take advantage of the low costs involved, and DWDM-based services. The new network also needed to provide a cost-effective alternative to uncompressed HD in the form of JPEG2000 video encoding. Faced
