Embodiment Construction

[0060] The present invention will be described in detail below in conjunction with specific application scenarios. In this application scenario, the Figure 5 The agent diagram shown is illustrated as an example.

[0061] Wherein, this application scenario includes: (1) the client, that is, the client authenticated by the authentication server, can enable proxy for other clients. (2) Other clients, that is, clients that have not been authenticated by the authentication server, hope to be able to access the network through the client. (3) The access device, that is, the network access device, can work at the network access layer, forward the access protocol information from the client to the authentication server, and grant the client corresponding network access rights according to the result of the authentication server , for example, the access device may be a device such as a switch, a router, or a firewall. (4) The authentication server is used to verify the identity in...

Abstract

The invention discloses a message transmission method and equipment. The method comprises the following steps: when a client receives a message, judging whether a tag is carried in the message or not; if yes, judging whether the tag is legal; and if no tag is carried in the message or the tag is illegal, discarding the message. The invention can effectively prevent other clients from accessing networks through starting an agent client.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a message transmission method and equipment. Background technique [0002] In an ordinary billing network (such as an education network), when a user performs an online operation, a specific user name and password are required to authenticate the online, and perform user fee settlement. If a certain client enables the proxy (Proxy) function, multiple clients can access the Internet through one client, thus avoiding the need for authentication before multiple clients can go online. Similarly, in an enterprise network, a certain server can also be used as a proxy, and other clients can access the Internet through the proxy. [0003] Wherein, the agent is a kind of software working at the application layer, which is used for operations such as message forwarding, and agents of different protocols are used for processing specific protocol messages. For example, an HTTP (Hype...
