Duplex asynchronous communication machine of Enterprise Service Bus

To achieve high system reliability, high availability, and concurrent processing capabilities, we often use some Server Load balancer devices (such as F5) for cluster solutions. However, there may also be some special situations, such as persistent connections and special technical protocols, which are not applicable to devices such as F5. duplex asynchronous communication machines act as soft F5.

The architecture of Duplex asynchronous communication machine is as follows:

 

Based on the deployment architecture, the duplex asynchronous communication machine can support "upstream" or "downstream ". Its main functions are duplex Asynchronization, load balancing, fault detection isolation, dual-machine Hot Standby (Heartbeat), etc. The combination of the upstream communication machine and [email protected] is mainly used for duplex asynchronous access to the ESB, which serves as a multi-path ESB load balancing and can also be used for front-end server access.

Server Load balancer:

1. achieve multi-channel load balancing;

2. Implement the platform's pure asynchronous capability and adopt the Message Queue mode;

3. Support for upstream and downstream loads;

Protocol Adaptation:

1. Supports TCP short-and-short connections (synchronous and asynchronous );

2. support access to HTTP, WebService, and other web protocols;

3. MQ and JMS connections are supported;

4. Support access to other common protocols and custom protocols;

Fault Tolerance:

1. Implement the ESB loop health detection function;

2. implement automatic ESB loop, manual fault isolation and recovery;

3. The communication machine itself detects faults and restarts the service and reconnects to the application;

4. The communication machine supports HA (master-slave dual-host) deployment;

Management and monitoring:

1. Protocol management, dynamic maintenance, expansion, and management of communication protocols;

2. Queue Management;

3. Fault maintenance management;

4. Exception monitoring;
