The design for Ethernet Access Concentrator

Increasing residential and business demand for faster Internet connections has resulted in huge incremental revenue opportunities for broadband access providers. Ethernet is a good technology to provide broadband access service to users. The key problem for Ethernet LAN access is how to support authentication, authorization and accounting features.
