How does PurePacket work with the Internet Protocol and with routers?
PurePacket provides both layer two and layer three transport services for IP. Layer two transport through the access network is especially useful in cases where the administration of the IP network is not the responsibility of the access network provider. A layer two access network is fully transparent to IP and the need to coordinate configuration between the two administrations is minimized. Layer three transport requires coordination at the IP level but provides more advanced tools for traffic management and troubleshooting. Both IP transport modes are suitable for public Internet Access and for the provisioning of secure corporate LAN-IC services. The connection towards the IP backbone router can be based either on Ethernet, PPP over SONET, MPLS or ATM.
