Ethernet also has preamble and inter-frame gap when transmitting. The preamble takes up 8 bytes (byte), or 64 bits. The first 7 bytes of the preamble are separated by 10101010, 1 and 0. However, the eighth byte becomes 10101011. When the host detects two consecutive 1s, it will know that there is data at the beginning. During network transmission, the data structure is as follows:

1927年对共产党来说是血雨腥风的一年。在不到半年的时间内，中共中央两次被迫迁移。第一次是从上海迁往武汉，第二次则是从武汉迁回上海。两次迁移，都是因为猝不及防地遭到过去的盟友国民党的突然袭击。 中共武装反蒋后把中央领导机关秘密建立在上海。首先是因为中共没有稳定的根据地，只能选择在群众基础较好的大上海；其次是因为上海有租界，租界区华洋杂居、政出多门，各种势力矛盾重重，且租界区不查户口、交通便利。在租界区，国民党的警察、宪兵和特务不能随便执行“公务”，更不能开枪、捕人。租界巡捕房捉到共产党，国民党当局只能通过法律程序进行“引渡”。“国中之国”的这种特性正好可以加以利用，寻找掩护的职业和场所，设立党的机关，进行秘密活动。 在这种错综复杂、暗流涌动的大历史背景下，如何有效地保卫处于秘密状态下的首脑机关，成为中共中央一切工作重中之重。于是，由周恩来首倡，在原中央军委特务工作处的基础上，筹建了“中央特科”这个政治保卫机构。 电视连续剧《江南锄奸》正是以此为背景，表现了那个年代中共特科在党

In TCP implementation, when receiving the SYN request from the client, the server needs to reply the SYN + ACK packet to the client, and the client also needs to send the confirmation packet to the server. Usually, the initial serial number of the server is calculated by the server according to certain rules or adopts random numbers. However, in SYN cookies, the initial serial number of the server is obtained by hash operation and encryption of the client IP address, client port, server IP address, server port and other security values, which is called cookie. When the server suffers from SYN attack and makes the backlog queue full, the server does not reject the new SYN request, but replies the cookie (SYN serial number of the reply packet) to the client. If it receives the ACK packet from the client, the server subtracts 1 from the ACK serial number of the client to obtain the cookie comparison value, and performs a hash operation on the above elements to see if it is equal to the cookie. If equal, complete the three-way handshake directly (Note: At this time, you don't need to check whether this connection belongs to the backlog queue).
