The selective repeat protocol (SSR) was a protocol used to solve the problem of frame loss or error in data transmission. The sliding window mechanism played an important role in the selective replay protocol. The sender had three things to do: 1. ** Calling from the upper layer **: After receiving data from the upper layer network layer, the sender checks the next sequence number that can be used for the frame. If the sequence number is within the sending window, the data frame will be sent. Otherwise, like GGN (which may be some other protocol), the data will either be stored in the buffer or returned to the upper layer before being transmitted. 2. ** Received an acknowledgment **: If an acknowledgment is received, if the frame number is within the window, the sender will mark the acknowledged frame as received. If the frame number is the lower bound of the window (the number corresponding to the leftmost window), then the window moves forward to the unconfirmed frame with the smallest number. If the window has moved and there are unsent frames with sequence numbers in the window, these frames are sent. 3. ** Time-out event **: Each frame has its own timer. After a time-out event occurs, only one frame will be retransmitted. There were also three things that needed to be done to the receiver: 1. The PR receiver will acknowledge a correctly received frame regardless of whether it is in order or not. The out-of-order frames would be stored in the buffer and sent back to the sender with a confirmation frame (whoever received it will confirm it). Until all the frames (i.e., the frames with lower serial numbers) were received, a batch of frames could be delivered to the upper network layer in order, and then the sliding window could be moved forward. 2. If a frame outside the window number and smaller than the lower bound of the window is received, an acknowledgment will be returned. Otherwise, the frame will be ignored. The SSR protocol was different from the protocol that accumulated acknowledgement to cause mass retransmissions (such as GGN). It set up a single acknowledgement, increased the receiving window, and designed the receiving buffer to buffer the frames that arrived out of order, so that only the wrong frames could be retransmitted and unnecessary mass retransmissions could be avoided. "Choose" was equally exciting. Everyone was welcome to read it!

For the players in World Mobile Games who wanted to spend money on the game, they could consider the following professions: 1. [Wildfire profession: Its main skill, Wound, is a sword-type martial arts skill. Its attack power increases according to the player's maximum health points. It does not consume skill points but consumes a certain percentage of health points.] After using it, the target will be inflicted with the negative status of "injured tendons and broken meridians", reducing the healing effect of the target's skills by 50% for a period of time. This status cannot be removed and has a great advantage. 2. [Tianji Profession: Main skill "Martial Arts" is a top-tier sword skill. It can only be used when HP is below 50%.] After being released, it will quickly rush towards the enemy, and its attack power will increase sharply. At the same time, it will reduce the enemy's HP by 10%(no more than 3083) and stun them for 2 seconds, making up for the lack of Tianji's melee outburst. 3. [Feather Profession: The main skill, Night Wolf, is a top-notch archery skill.] When used, it will condense essence, qi, and fire an arrow, greatly increasing attack and accuracy and ignoring the target's defense. If it hits the target, there is a chance to reduce the target's defense. It is good at long-range damage. Each of these classes had their own characteristics. Players could choose based on their own preferences and game style. The original novel of the TV series "The Unique Empress of Generals" was called "The Rebirth of the Poisonous Empress of Generals."
