As of October 2009, the CNGI effort comprises six nationwide backbone networks and 39 GigaPOPs (Gigapop is short for gigabit point-of-presence, an access point to Internet2), which extends the next generation footprint to over 20 major cities and over 300 academic, industrial, and government research campuses within China. Five backbones are commercial (operated by China Telecom, China Unicom, China Netcom/CSTNET, China Mobile, and China Railcom), with an additional academic research network operated by CERNET, which is known as CNGI-CERNET2. CNGI also encompasses two exchange points (IX) in Beijing (named CNGI-6IX) and Shanghai for interconnecting these backbones and for international links to APAN (Asia Pacific Advanced Network), GEANT, and Internet2.
