This disclosure provides a message transmission method, apparatus, electronic device, related medium, and program product. The message transmission method includes: generating a data packet; wherein a first field in the data packet has a first original port number; determining that a first original path from the sending device to the receiving device is congested based on a congestion window value corresponding to the current routing period of the sending device; selecting a first virtual port number corresponding to the current routing period from a first set of candidate port numbers, updating the first field with the first virtual port number, and placing the first original port number in a second field of the data packet; the first virtual port number is used for routing calculations to obtain a first alternative path from the sending device to the receiving device; and sending the data packet so that after receiving the data packet, the receiving device extracts the first original port number from the second field and updates the first field with the first original port number for transport layer protocol processing. This disclosure can effectively improve message transmission efficiency.

The utility model relates to the technical field of freshwater fish culture, and discloses a wastewater treatment device for a freshwater fish culture pond, the wastewater treatment device comprises a base, a treatment shell is arranged in the middle of the upper surface of the base, and a first liquid storage structure and a second liquid storage structure are symmetrically arranged on the two sides of the treatment shell; a first treatment cavity and a second treatment cavity which are inclined are formed in the treatment shell, the first treatment cavity and the second treatment cavity are distributed in the treatment shell in an up-down cross mode, and a first filtering mechanism and a second filtering mechanism are detachably installed in the first treatment cavity and the second treatment cavity correspondingly; and a rotating shaft is fixedly mounted at the bottom of the treatment shell, and one end of the rotating shaft penetrates out of the rotating groove and is fixedly provided with a crank. The first filtering mechanism is cleaned, meanwhile, the waste water treatment work is not affected, and the waste water treatment efficiency is improved.

The utility model discloses a workpiece clamping tool which comprises two rocker arms, one end of each rocker arm is provided with a jacking column used for jacking a workpiece, and the other end of each rocker arm is provided with an opening and closing column used for controlling the rotating motion of the rocker arms. The device further comprises a control rod, a control circular truncated cone is arranged at the end of the control rod, an opening and closing circular truncated cone is arranged at the end of each opening and closing column, the opening and closing circular truncated cones of the two opening and closing columns are aligned, the control circular truncated cones are perpendicular to the two opening and closing circular truncated cones and make contact with the two opening and closing circular truncated cones respectively, and when the control rod extrudes the two opening and closing circular truncated cones, the opening and closing circular truncated cones are opened and closed. And the two opening and closing circular truncated cones are separated outwards, so that the two rocker arms rotate outwards, and the jacking columns rotate inwards to clamp a workpiece. A workpiece is clamped and fixed from the side face, machining of the top face is not affected, manual control clamping is suitable for various box bodies of different specifications and sizes, and convenience and practicability are achieved.
