Distributed load balancing system, health check method, and service node
First Claim
1. A distributed load balancing system, comprising a cloud management platform, an access node, and at least one service node, wherein the access node, a the first node, and the at least one target service nodes are physical servers, a first virtual load balancer runs on the access node, and at least one backend server runs on each of the one or more target service nodes, wherein a first node programmed to:
- determine, by the cloud management platform, according to an identifier of a service, multiple target backend servers providing the service, and a network address of each target backend server of the multiple target backend servers;
determine, by the cloud management platform, an identifier of one or more target service nodes on which the multiple target backend servers are located; and
send, by the cloud management platform, a check request message to each target service node, wherein each check request message carries a network address of a target backend server running on a target service node that can receive the check request message, and the identifier of the service;
wherein each target service node is programmed to;
receive the check request message sent to the target service node, and send the network address of the target backend server running on the target service node carried in the check request message to a detection module corresponding to the identifier of the service carried in the check request message;
send, by the detection module, according to the received network address, a detection message to the target backend server corresponding to the received network address to detect a status of the target backend server; and
share, by the detection module, the status of the target backend server to the first virtual load balancer on the access node; and
wherein access node is programmed to;
obtain, by the first virtual load balancer, a status of the target backend server on each target service node, and update, according to the status of the target backend server on each target service node, a recorded status of the backend server providing the service.

Abstract
A distributed load balancing system includes a cloud management platform, an access node, and at least one service node, where the access node and the at least one service node are physical servers, a first virtual load balancer runs on the access node, and at least one backend server runs on the service node. A detection message is sent by using a detection module on a target service node to detect a status of a target backend server, and the status of the target backend server is shared to a first virtual load balancer by using the detection module. Therefore, not only a quantity of detection messages in the load balancing system is reduced, but also signaling load on the access node is reduced.

9. A health check method in a distributed load balancing system, comprising:
-
determining, by a first node according to an identifier of a service, multiple target backend servers providing the service, and a network address of each target backend server of the multiple target backend servers; determining, by the first node, an identifier of each target service node on which the multiple target backend servers are located; and sending, by the first node, a check request message to each target service node, wherein each check request message carries a network address of a target backend server running on a target service node that receives the check request message, and the identifier of the service; receiving, by each target service node, the check request message, and sending the network address of the target backend server running on the target service node to a detection module corresponding to the identifier of the service carried in the check request message; sending, by each target service node according to the received network address, a detection message to the target backend server corresponding to the received network address to detect a status of the target backend server; and sharing, each target service node, the status of the target backend server to a first virtual load balancer on an access node; and obtaining, by the access node, a status of the target backend server on each target service node, and updating, according to the status of the target backend server on each target service node, a recorded status of the backend server providing the service. - View Dependent Claims (10, 11, 12, 13, 14)
