AI Technical Summary
In load balancing devices, during port reuse, port reuse may fail because the initial sequence number of the next communication session is less than the FIN sequence number of the previous communication session. This is especially true in scenarios involving long connections or high-speed uploading of large files, where successful port reuse cannot be guaranteed.
By obtaining the FIN packet sequence number of the first communication session, the retention period is determined based on a preset relationship, and the initial sequence number of the second communication session is adjusted within this period to be greater than the sequence number of the first communication session, thus ensuring successful port multiplexing.
This effectively avoids port reuse failures, improves the port reuse success rate, and ensures normal handshakes and data transmission between different client devices and the server.
