Method, device, and network system of establishing a tunnel

摘要

A method, a device, and a network system of establishing a tunnel are provided in embodiments of the present disclosure. The method of establishing the tunnel includes: obtaining, by a WTP, an address of an AC and an address of a BRAS from a DHCP server; using, by the WTP, the address of the AC to establish a CAPWAP control tunnel with the AC; and using, by the WTP, the address of the BRAS to establish a CAPWAP data tunnel with the BRAS. By using the technical scheme provided in the embodiments of the present disclosure, the CAPWAP data tunnel may be established between the WTP and the BRAS.

1. At a wireless termination point (WTP) in a mobile communication network that uses an access control point (AC) to access the internet, a method of mitigating a bottleneck effect of the AC when a large number of terminal devices want to access the Internet by establishing a tunnel, the method comprising:
obtaining, by the WTP, an address of an access control point (AC) and an address of a broadband remote access server (BRAS) from a dynamic host configuration protocol (DHCP) server; using, by the WTP, the address of the AC to establish a control and provisioning of wireless access points protocol (CAPWAP) control tunnel with the AC; and using, by the WTP, the address of the BRAS to establish a CAPWAP data tunnel with the BRAS.
