A multi-operators sharing links authentication method based on PPPoE and virtual private network

The traditional operators' access authentication methods are hard to realize the link sharing of multi-operators. According to the university campus with multiple network operators including Telecom, Unicom, Mobile and local network, an authentication method based on PPP over Ethernet (PPPoE) and virtual private network (VPN) is proposed to share a same link for multiple network operators. A uniform network sharing architecture for multi-operators is designed and the multi-operators dial-up authentication client programs for Windows and Linux are realized. Experimental results show the method has good secure performance and meets requirements of different users.
