Sending message more than 4kB using WAN-TCP tunneling over DDS method

[Tim-ThanaphatJ]

I am currently working on WAN-TCP tunneling over DDS. When running using a integration-service. After subscriber for my topic matched. I see the following message on the subscriber [RTCP_MSG_IN Error] Bad RTCP header identifier, closing connection. -> Function Receive

I am running the following

• A publisher are publishing 15 topics. Each topic contains data with:
  - Size of the message: 2kB
  - Frequency: 40 hz
• wan_config.xml
  - TCPv4
  - Number of listening port: 1

Note If I publish only 2 topics, the error will not came up.

Question

• What is the maximum size of the message and maximum bandwidth that WAN-TCP tunneling over DDS allows for sending message?
