the data link layer, for example, if you send 512 Byte, received is not necessarily the correct byte, so you have to make the relevant check to ensure correctness, or may not be a complete copy of the byte, but a number of times to collect all the data, then we need to define the relevant structure to ensure the integrity of data transceiver. These details are related to the serial drive implementation, readers are interested in, you can view the relevant documents. In this application, there i

Playing VPS often uses port forwarding to achieve faster speeds. For example OVH computer room network My visit here is very slow, with Remote Desktop will vomit blood type. So they use other routes as a springboard, like Los Angeles, Hong Kong, and so on. Another example if you need a Japanese IP, but local access to Linode, Conoha Japan are detours, and slow, then if you use a Hong Kong VPS to do relays,
