Compared with SYN cache method, SYN? Cookies technology does not need to allocate space at all when receiving a SYN. Because the most basic data that make up the connection state are encoded and compressed into the sequence number bits of SYN-ACK. For a legitimate connection, the server will receive an ACK message segment with a serial number (actually the serial number has been added by 1), then the basic TCB data will be regenerated, and a complete TCB will confirm that the data will be safely instantiated through decompression. This decompression can be successful even under severe attacks, because there is no storage load at all on the host side, only the load that calculates the encoded data into the ACK sequence number. The disadvantage is that not all TCB data can be added to the 32-bit sequence number segment, so some TCP options required for high performance cannot be encoded. Another problem is that such SYN-ACK message segments will not be forwarded (because forwarding requires complete state data).

The other two schemes are based on SYN cache and SYN? Cookies (see 6.4), simplifies the state initialized when the TCB is generated by receiving the SYN, and delays the instantiation of the full state [4]. In hosts that use SYN caching, a HASH tablespace with a limited size is used to store a subset of data that will be allocated to the TCB. If the ACK is received when the handshake is completed, the data will be copied into a complete TCB, otherwise HASH values exceeding the lifetime will be recycled when needed. In Lemon's FreeBSD, the SYN cache is 160 bytes for a half-open connection, while a full TCB is 736 bytes and supports 15,359 SYN cache spaces.

"The first few hours of the battle were the same as before, We use all kinds of weapons in our hands in our positions. Strike the attacking Vietnamese troops, The exchange of fire was very intense, The front of the position was covered with the bodies of the Vietnamese army. We also have a lot of wounded on our side, However, after all, it is based on strong fortifications. More wounds, less deaths, In particular, the wounded are mainly minor, All of them can continue to fight without getting off the line of fire. At that time, my monitor was quite happy. If you play like this, There's not much pressure to hold position 149, The Vietnamese army that could fight could not even get close 400 meters away from the front of the position, As a result, it was only over an hour after he said this. I remember it was one or two o'clock in the afternoon. Something is wrong, The left and right wings of the position, It's two sparse rain forests, The positive was the same, But before the war, in order to facilitate the offensive forces to assault, All of them have been cut down by Vietnamese troops, But it also broadens our horizons, However, it is still unclear what is going on in the rainforest on both sides. Just when something was wrong, First I heard a "buzzing" sound inside, At first it was a little bit, Later it grew bigger and bigger, At last it was so big that it could almost cover the shot when it was fired. No one in our position knows what's going on, All of them stretched out their heads and looked in the direction of the sound. When the "buzzing" sound reached its peak, they saw that a large area of flying insects flew vertically from the rainforest on both wings. If the number were small, whether the sound or flying insects could not be heard or seen at this distance, but now they could hear clearly.

据导演何群透露，《新青年》将区别于传统主旋律史诗剧的严肃刻板，适当加入轻喜剧的叙事成分，呈现一种幽默的风格。何群曾表示，该剧涉及辛亥革命、二次革命、新文化运动、第一次世界大战、五四运动、中国共产党成立、南昌起义等历史事件，但采取的不是正面强攻的方式，而是聚焦大历史背景中的小人物命运。
