IGMP means Internet Group Management Protocol. This protocol is used to establish and maintain multicast group membership between IP host and its directly adjacent multicast routers, but does not include the dissemination and maintenance of group membership information between multicast routers.

Therefore, when buying the network cable, you can reduce a 0.5 meter long network cable and pull it to both sides. See if there is a crack in the middle or if the epidermis can extend to both ends. If there is no crack in the middle during the pulling process, and the epidermis can also extend to both ends, then the epidermis of this network cable meets the standard. In addition, we should pay attention to a problem. In the process of pulling, although some network cables have no cracks, there are obvious signs of whitening and thinning in the middle, which is also not in line with the standard.

It reduces the coupling degree between data structures and operations acting on data structures, making the set of operations relatively free to change. The specific structure diagram is as follows:
