Method, system and device for accessing campus network to external network

Abstract

The invention discloses a method, a system and a device for accessing a campus network to an external network. The method comprises the following steps that: A) an authentication gateway receives a network access request transmitted by a terminal, a step B) is executed if the destination address of the request is an address inside the campus network, and a step C) is executed if the destination address of the request is not an address inside the campus network; B) the authentication gateway routes a data packet of the terminal accessed network to the inside of the campus network; C) the authentication gateway pushes a web authentication page to a user using the terminal, and receives an account type and an account number which are returned by the page, a step D) is executed if the account number is a type I account number, and a step E) is executed if the account number is not the type I account number; D) the authentication gateway initiates an authentication request to a local authentication accounting server, and controls the user to access the external network through a first outlet of the campus network after passing the authentication; and E) the authentication gateway initiates an authentication request to a remote authentication accounting server, and controls the user to access the external network through a second outlet of the campus network after passing the authentication. The invention is used for realizing a cooperatively operating campus network.

Description

technical field [0001] The invention relates to the interconnection technology between different networks, in particular to a method, system and device for realizing campus network access to an external network. Background technique [0002] With the continuous improvement of the network demand of colleges and universities, the campus network of colleges and universities usually has an additional network export of operators in addition to the export of China Education and Research Network (CERNET, China Education&Research Net); it has also become a trend for colleges and universities to cooperate with other social forces to build and operate campus networks . The campus network has gradually shifted from single-exit (CERNET), single-authentication and billing management (school) to multi-exit (CERNET and one or more operator network exits), multi-authentication and billing management (school and cooperative With the development of the campus network, multiple outlets, multi...

Problems solved by technology

[0006] For the simplified network structure of the campus network, due to the different network usage conditions of campus network users and home network users, there are a large number of internal data exchange and resource sharing in the campus network, and the use of the two-layer network and PPPOE authentication makes the BAS overburdened. And it is not conducive to the security of the campus network;

[0007] For simplified authentication management, the campus network jointly established by multiple parties is independently authenticated and billed by one party. Even if the other party is given the client query authority, it is still difficult to achieve comprehensive supervision due to the workload; Part of the campus network invested and constructed is independently managed, and there are problems such as redundant construction, inability to share resources, and the inability of the school to manage and supervise the use of some campus networks. For the academic database resources purchased by the school based on the school’s IP address certification, non-school certification users have difficulty accessing

[0008] To sum up, for a campus network with multiple exits and multiple authentications, the existing methods cannot access the external network under the rules set above
