Network Connection Description
Last updated:2026-01-23 17:34:04
TDMQ for RocketMQ supports both private network access and public network access, with different connection requirements for different network types.
Connection Description
Connection Method | Connection Description | 5.x Cluster | 4.x Exclusive Cluster and General Cluster | 4.x Virtual Cluster | Documentation |
Private network connection | If the client and the TDMQ for RocketMQ cluster are deployed in the same Virtual Private Cloud (VPC) network, they can interconnect with each other by default, and no additional configuration is required. | ✓ | ✓ | ✓ | / |
| If the client and the TDMQ for RocketMQ cluster are deployed in different VPC networks, they cannot communicate with each other directly because different VPC networks are logically isolated. To enable VPC networks in different regions under the same account to communicate with each other, use Cloud Connect Network (CCN). | ✓ | ✓ | ✓ | |
Public network connection | A dedicated public network route needs to be configured for clients to connect to the TDMQ for RocketMQ cluster through the public network. Since public networks are accessible from any environment, security policies need to be configured to ensure connection security. | ✓ | ✓ | × | |
Normally, it is recommended that you prioritize private network access to achieve lower network latency, higher transmission bandwidth, and better security isolation, especially for core businesses in production environments. Public network access can be enabled when your businesses need to provide services or conduct development and debugging through the public network. When public network access is enabled, it is recommended that you configure security policies to strictly restrict access to IP addresses to ensure data security.
Port Description
The following table lists the ports that need to be enabled before a client connects to a TDMQ for RocketMQ cluster. These ports are enabled by default when you use TDMQ for RocketMQ features.
Direction | Protocol | Port | Source IP Address | Description |
Inbound | TCP | 8080 | IP address or address group where the TDMQ for RocketMQ client resides. | Port for accessing TDMQ for RocketMQ 5.x clusters using Transmission Control Protocol (TCP). |
Inbound | TCP | 9876 | IP address or address group where the TDMQ for RocketMQ client resides. | Port for accessing TDMQ for RocketMQ 4.x clusters using TCP. |
Inbound | TCP | 5576 | IP address or address group where the TDMQ for RocketMQ client resides. | Port for accessing TDMQ for RocketMQ 4.x clusters using Hypertext Transfer Protocol (HTTP). |
