Problems solved by technology

[0008] In the prior art, there is no way to issue QoS (Quality of Service) to clients. When there are a large number of clients online, the instantaneous traffic will be very large (for example, the size of a single webpage is about 500K, and when 50 clients are simultaneously When accessing, the instantaneous traffic reaches 24M), and because QoS cannot be realized, it will affect the receiving traffic of the client and seriously affect the user experience

Embodiment Construction

[0025] The present invention proposes an SSL VPN-based data forwarding method, which is applied to a system including SSLVPN equipment, a client, and an intranet server. The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. by figure 1 To refer to the network model diagram, the SSL VPN device is in the figure 1 The middle one is the SSL VPN gateway. The client connects to the SSL VPN gateway through the Internet, and then connects to the intranet server.

[0026] In the present invention, when defining the client on the SSL VPN device, QoS identification information can be set for the client according to the type of the client (such as an important client, a client with high real-time requirements, etc.), and the QoS identification information is represented by qos -local-id value (qos-local-id value can be any data between 1-4095 in actual application) as an example, so that the QoS classifier can d...

Abstract

The invention discloses a method and equipment for forwarding data based on a security socket layer (SSL) virtual private network (VPN). The method comprises: when SSL VPN equipment receives the data sent from an intranet server to a client, the SSL VPN equipment inquires a session table item through address information carried in the data, distinguishes the data of the client through inquiring the corresponding quality of service (QoS) identification information in the conversation table item and forwards the distinguished data based on a QoS strategy. In the invention, the bandwidth of a network can be reliably utilized, and the safety of the equipment is improved.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to an SSL VPN-based data forwarding method and equipment. Background technique [0002] SSL (Security Socket Layer, secure nested word layer) VPN (Virtual Private Network, virtual private network) is an emerging VPN technology, with HTTPS (Secure Hyper Text Transfer Protocol, secure hypertext transfer protocol, that is, the HTTP protocol that supports SSL) It is widely used in Web-based remote security access, providing security guarantee for clients to remotely access the company's internal network. [0003] The typical networking architecture of SSL VPN is as follows: figure 1 As shown in the figure, the administrator creates resources corresponding to the enterprise's intranet server on the SSL VPN gateway. When a remote access user (that is, a client) accesses the intranet server, an HTTPS connection is established with the SSL VPN gateway, and the resource to be ...
