Short for gigabit Point of Presence, a network access point that supports data transfer rates of at least 1 Gbps. Currently, only a few gigaPOPs exist, and they're used primarily for accessing the I2 network. Each university that connects to I2 must do so through a gigaPOP, which connects the university's LANs and WANs to the I2 network. Originally, 12 gigaPOPs were planned, each one serving half a dozen I2 members, but the number of gigaPOPs is likely to grow.
Whereas the POPs maintained by ISPs are designed to allow low-speed modems to connect to the Internet, gigaPOPs are designed for fast access to a high-speed network, such as I2.
