Problems solved by technology

[0004] If a single load balancer is assumed in front of this group of load balancers, the link bandwidth and processing power of this load balancer will become a bottleneck and cannot provide scalability for application server clusters

Embodiment Construction

[0042] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0043] figure 1 It is a flow chart of the load balancing method provided by the embodiment of the present invention. like figure 1 As shown, the method includes the following steps:

[0044] Step 101, the router selects the first load balancer from the first load balancer group according to the path weight vector;

[0045] Step 102, the first load balancer receives the first data packet sent by the router, encapsulates the first data packet, and obtains the second data packet;

[0046] Step 103, the load balancing manager assigns a virtual network address to the second load balancer in the second load balancer group;

[0047] Step 104, the load balancing manager queries the first IP address and the first port information of the second load balancer, and sends them to the first load balancer;

[0048] Step 105, the...

Abstract

The invention relates to a load balancing method and a system. The load balancing method comprises the steps: a router selects a first load balancer from a first load balancer group; the first load balancer receives a first data packet sent by the router and performs packaging treatment to obtain a second data packet; a load balancing manager distributes a virtual network address for a second load balancer in a second load balancer group, inquiries a first IP address and first port information of the second load balancer and sends the first IP address and first port information to the first load balancer; the first load balancer sends the second data packet to the second load balancer according to the first IP address and first port information; the second load balancer processes the second data packet to obtain a third data packet. The system comprises the router, the load balancing manager, the first load balancer and the second load balancer. The bandwidth bottleneck problem of the load balancer groups under a large-scale scene can be solved.

Description

technical field [0001] The invention relates to the field of computers, in particular to a load balancing method and system. Background technique [0002] With the rapid development of mobile Internet and cloud computing, the number of users of network applications is increasing day by day. The application and research of how the corresponding application server cluster can be expanded to carry massive data has attracted widespread attention. [0003] The load balancing technology sets up a load balancer at the front end of the server cluster, and reasonably forwards application requests to the corresponding servers according to the load balancing algorithm, which provides certain scalability for the application server cluster. However, in the face of today's huge user scale, a single load balancer cannot carry user requests. Therefore, a group of load balancers are needed to jointly undertake load balancing tasks, and each load balancer is in the same subnet as an applicat...
