Problems solved by technology

[0008] However, load balancers are generally expensive, and such settings will greatly increase the deployment cost of SSL VPN gateways
At the same time, the load balancer will also reduce the performance of network communication to a certain extent, especially when the performance of the SSL VPN gateway cluster is high, but the performance of the load balancer is low, and the load balancer becomes a performance bottleneck

Embodiment Construction

[0025] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0026]The invention discloses a method for realizing gateway dynamic load distribution, which mainly includes the following steps: (1) Configure gateway cluster parameters: each gateway in the SSL VPN gateway cluster enables the VRRP protocol, and sets the same VRRP for each gateway Virtual addresses and different priorities; at the same time, different internal network IP addresses and external network IP addresses will be set for the gateway. (2) Select the master gateway: set one of the gateways (for example, the gateway with the highest priority) as the master gateway (Master), and the...

Abstract

The invention relates to the technical field of network data transmission and discloses a method for achieving gateway dynamic load distribution. The method for achieving the gateway dynamic load distribution mainly includes the following steps: (1) parameters of a gateway cluster are configured; (2) a main gateway is chosen; and (3) dynamic load redirection is conducted, wherein after the main gateway with a virtual router redundancy protocol (VRRP) virtual address receives a security socket layer (SSL) access request of a user terminal, the main gateway selects one gateway of the gateway cluster to serve as a target gateway of the access request and sends a message which is redirected to the target gateway to the user terminal. According to the method for achieving the gateway dynamic load distribution, hardware investment of a load distributor is reduced. The main gateway only needs to be set in the gateway cluster, and then the gateway dynamic load distribution can be achieved. Load balancing of an SSL virtual private network (VPN) gateway cluster is achieved to a certain degree, and the cost is lowered. The problems of the high cost caused by the load distributor and a system performance bottleneck are solved. The load distributor is not adopted, and then the gateway dynamic load distribution can be achieved fast.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method for realizing dynamic load distribution of a gateway without a load balancer. Background technique [0002] The Virtual Router Redundancy Protocol (VRRP for short) is a routing protocol proposed by the IETF to solve the single-point failure phenomenon of configuring static gateways in LANs. In 1998, the official RFC2338 protocol standard was released. VRRP is widely used in edge networks. Its design goal is to support the failover of IP data traffic under certain circumstances without causing confusion, allowing the host to use a single router, and maintaining the router in the event that the actual first-hop router fails. connectivity between. [0003] SSL is the abbreviation of Secure Socket Layer (Secure Socket Layer Protocol), which can provide confidential transmission on the Internet. SSL adopts public key technology, and its goal is to ensure the confident...
