Embodiment Construction

[0028] The technical problem to be solved by the present invention is: no special load balancing equipment is needed, but a cluster composed of multiple SSL VPNs can complete the functions of load balancing, redundant backup, and external virtualization as one device.

[0029] The system of the present invention includes one SSL VPN device as a master control node and several SSL VPN devices as working nodes. All SSL VPN devices run with an intra-group synchronization module, and the master control node SSL VPN device runs with four processing modules: a load management module, an address responder, and a data shunt.

[0030] Master control node.

[0031] The master control node is the one with the strongest network connection processing capability among all SSL VPN devices. It is used for establishing external connections and internal load balancing of the entire SSL VPN cluster, and is responsible for establishing and maintaining SSL secure connections for different data str...

Abstract

The invention provides a balanced load SSL VPN (security socket layer, virtual private network) device cluster system and an operating method thereof. The balanced load SSL VPN device cluster system comprises an SSL VPN device serving as a master control node and a plurality of SSL VPN devices serving as worker nodes. An intra-group synchronous module is disposed in each of the SSL VPN devices. The SSL VPN device serving as the master control node is further internally provided with a load management module, an address transponder and a data divider. A cluster centrally provides a globally set virtual IP (internet protocol) address to the outside; the virtual IP address is used as a DNS (domain name server) resolution address for a virtual single SSL VPN device; the whole SSL VPN device cluster is connected with a network node and a server. The balanced load SSL VPN device cluster system and the operating method thereof have the advantages that the operating IP address of the SSL VPN cluster of different SSL VPN devices is unique, load balance and redundant backup are effective, the cost is lowered, and reliability is high.

Description

technical field [0001] The invention belongs to the field of data communication, and relates to a load-balanced SSL VPN device cluster system and a working method thereof. Background technique [0002] SSL VPN: A technology that uses the SSL-Security Socket Layer (Secure Socket Layer) protocol and the TLS-Transport Layer Security (Transport Layer Security) protocol to establish a private network on a public network to provide security and data integrity protection for network communications. A technology that encrypts and protects network connections at the transport layer. SSL VPN is widely used for identity authentication and encrypted data transmission between web browsers and servers. [0003] The typical application mode of SSL VPN is to serve as a secure access server at the central end, providing identity authentication and secure access services for thousands of browser users while protecting the central end Web server. Therefore, SSL VPN devices have very high req...
