About the CORE

The PHNET Common Routing Exchange (CORE) is a not-for-profit, settlement-free, layer 2, exchange point for routing Intra-Philippine traffic. PHNET provides the rack space, 100 mbps switch, route reflector, and all other facilities for CORE participants. Participants provide their own router, router cables, and telecom circuit terminated at PHNET. Through PHNET's route reflector, the participants are able to exchange BGP4 routes with each other and exchange Internet traffic through the PHNET 100 mbps switch.

  2. CORE is a Telco-neutral exchange. Participants can choose their favorite telco to provision the circuit to PHNET.

  3. Faster access to and from other Philippine Internet sites.

  4. For research and academic institutions, transit to the Asia-Pacific Advanced Network

  5. Superior network management services provided by PHNET's technical staff.
