What does SSR protocol mean?
SSR was the short form of Shadowsocks R, which was an improved network protocol based on Shadowsocks. It was an upgraded version of Shadowsocks. It mainly added some new algorithms based on the original protocol to achieve higher speed and better encryption performance. The protocol is used to encrypted and protect network communication. It has powerful encryption capabilities and uses a variety of encryption algorithms to effectively protect the security of communication content. It provides high-speed and stable agent services. It implements fast and stable network agents based on the SOCKS5 agent. It supports multiple platforms, such as Windows, macs, linuxs, iOS, and Android. It is also an open source free project.

GGN and SSR
GGN (N-frame backward protocol) and PR (selective replay protocol) were two types of sliding window protocol. In the GGN protocol, the sender maintained a set of sending windows and could send multiple data frames at a time. The receiver used the cumulative acknowledgment method. After receiving the acknowledgment, the sender moved the sending window forward and retransmitted it by retreating N frames. The transmission window is a set of serial numbers of frames that are continuously allowed to be transmitted maintained by the sender. The frames within the window can be transmitted to improve the channel utilization. The receiver did not confirm each frame individually, but confirmed the last frame of a group of frames that arrived in order, indicating that the frame before the frame had been received. If a re-transmission is required, the sender must re-transmit all the sent frames after the acknowledgment frame. Furthermore, the receiver could only receive frames one by one in sequence, and the frames that were not in sequence were directly discarded. The larger the transmission window, the higher the channel utilization rate, but it could not be infinite. There was a maximum limit. When using n bit numbering, the transmission window could be as large as 2n - 1. The stop-and-wait protocol can be seen as the GGN protocol with a transmission window of 1. In the GGN protocol, the receiver could only receive in order, and the out-of-order frame could only be discarded, which would waste network resources. The SP protocol had a receiving window, and the receiver could buffer out-of-order frames to prevent them from being discarded, allowing it to receive more data at the same time. Since the received frames might be out of order, the cumulative confirmation method could not be used. Each received frame must be confirmed. After all the frames in the receiving window were received, it would be handed over to the upper layer, and the receiving window would be moved forward. The maximum value of the transmit window of the SSR protocol was 2n - 1, and the receive window was the same size as the transmit window. If the receive window was too small, the frame sent by the sender would be discarded because it could not be received and waste resources. If the receive window was too large, it would be meaningless for a fixed transmit window. "Choose" was equally exciting. Everyone was welcome to read it!
Continuous arq protocol and sliding window protocol
In the continuous ARQ protocol, the sender maintained a sending window of a certain size, and the packets within the window could be sent continuously without waiting for the other party's acknowledgment. The sender would slide the sending window forward by one packet every time it received an acknowledgment. The receiver usually uses the method of accumulating acknowledgement, that is, after receiving several packets, it sends an acknowledgement to the last packet that arrives in order, indicating that all the packets up to this packet have been received correctly. However, this method has shortcomings. For example, when the middle packet is lost, the sender cannot know the situation of the subsequent packets, and may need to re-transmit more packets. The sliding window protocol involves a sending window and a receiving window. The transmit window is the range of sequence numbers of the frames that have been sent but have not been acknowledged, and the receive window is the range of sequence numbers of the frames that are expected to be received. When the default window size is 1, you can operate according to the specific sending process. The sliding window protocol could improve the channel utilization and was a reliable transmission mechanism for data communication. The continuous ARQ protocol can be seen as a specific application form of the sliding window protocol under certain conditions (such as the cumulative acknowledgment method). They are all protocol mechanisms that exist to achieve effective and reliable data transmission in the network. "Choose" was equally exciting. Everyone was welcome to read it!

Mysterious Summoning SSR
In Onmyoji, there was a mysterious summoning array used to summon SSR shikigami. Every month, a new mysterious pattern would be refreshed. After triggering the mysterious pattern, one could receive a generous reward. For example, the mysterious pattern of October 2024 could be triggered by drawing a straight diagonal line from the bottom left corner of the pen to the third incantation from the bottom of the charm on the left and the fourth incantation from the top of the charm on the right. It could also be drawn from the top right corner to the bottom left corner. The mysterious pattern in July 2024 was not difficult to trigger. If there were two red cloths hanging down on the summoning interface, just draw a straight line along the left and right edges of the red cloth. If there were no red cloths, draw it outside the summoning circle (note that the horizontal line below must be drawn inside the summoning circle). Triggered by the mysterious summoning circle, the mysterious pattern might help summon the SSR shikigami.
ARP protocol
The Address Resolution Protocol was a network layer protocol. It was between the data link layer and the network layer. It played a vital role in network communication, just like the address translator in the network. Its main function was to convert the IP address of the network layer to the data link layer's IP address. This was because in network communication, although the IP address was used to identify the host at the network layer, it was forwarded through the IP address at the data link layer (such as the ether network). The host or the layer 3 network device would maintain an ARP-table to store the IP address and the MAC-address map. The ARP-table entries included dynamic and static ARP-table entries. The working process was as follows: When host A needed to communicate with host B, it first determined the forwarded IP address according to the route table, and then checked the local ARP-buffer. If there was no matching address, it would broadcast an ARP-request frame in the network. All hosts in the same broadcast domain will receive this request. For example, after receiving the request, host C will find that the destination address is not its own, and then it will buffer the address of host A into its own ARP-table, and then discard the packet. After receiving the request, host B will find that the destination address is its own, and then it will buffer the address of host A and give a response. Then it will package its own address in the response ARP-packet and send it to host A. After receiving the response, host A will update its own ARP-buffer. There were two ways to obtain the ARPs: static and dynamic. The static acquisition was equivalent to manually configuration of the address map in the ARP-table. If the physical address changed, it would need to be manually changed, which was more troublesome. The dynamic acquisition was to obtain and update the address map by the host through the protocol, which was relatively convenient. In addition, there was also a free ARP-type message that was used to detect whether there was an IP address conflict. It would send a broadcast message with the same source and destination IP. Under normal circumstances, it was not expected to receive a response. If a response was received, it meant that there was an address conflict. In the Windows system, there were related ARP-commands. For example, ARP-a could check the ARP-buffer table, and ARP-d could delete the ARP-buffer table. However, due to network communication requirements, the buffer table might be regenerated immediately. In November 1982, the Internet Engineering Task Force (IetF) published the Internet Packet Packet Interface Problem (ARPG) 826. It was an indispensable protocol for the Internet Packet Interface Version 4, which was the most widely used version of the Internet protocol.(The Internet Packet Interface Version 6 was still in the early stages of deployment.) The role of the ARP-protocol in the car's ether network was the same as that of the traditional ether network. "Choose" was equally exciting. Everyone was welcome to read it!
protocol translation
The price quoted for contractual translation was usually affected by many factors: 1. ** Language pair **: Common ones such as Chinese-English translation may cost 200 - 400 yuan per 1,000 words; translation between minor languages and Chinese may cost 300 - 500 yuan per 1,000 words. 2. ** The complexity of the agreement **: For general agreements, the terms are relatively common and simple, and the fee is relatively low, about 200 - 300 yuan/1,000 words; for agreements involving complicated legal terms, professional terms, and strict format requirements, the fee may be 350 - 500 yuan/1,000 words. 3. ** Delivery Time **: During the normal delivery period, the above standard charges will be applied. If the customer requests urgent delivery, an additional fee may be added. 4. ** Translator's Quality Requirement **: Standard quality, able to accurately convey the content of the agreement, moderate fee; High quality, accurate language, compliance with legal documents, high fee. In general, the price of the contract translation was about 200 - 500 yuan per thousand words. The specific price still needed to be confirmed in detail. In addition, the word "protocol" has different meanings in different scenarios. In the Internet industry, it has the meaning of "protocol"(for example, the full name of the IP address is Internet Protocol Address). In the political context, it is inclined to reach a political consensus, rule, or speech technique (such as political protocol). In the diplomatic context, it means a set of rules or etiquette (such as diplomatic protocol). When translating the protocol, you need to accurately understand the meaning of these words in different context. "Choose" was equally exciting. Everyone was welcome to read it!
Backward n frame protocol and selective repeat protocol
Go-back- N (GGN): - In the stop-and-wait protocol, the sender can only send one frame at a time, and the channel utilization rate is low. However, the backward N-frame protocol uses a sliding window method, and the sender maintains a set of sending windows, and can send multiple data frames at a time. The receiver uses the method of cumulative confirmation, and the sender moves the sending window forward after receiving the confirmation. When there was a problem (such as frame loss or long delay), the sender used the method of retreating N frames to re-transmit. The timer here was used to recover data frames or confirm the loss of frames, similar to the timer in the pause protocol. Choosing the Repeat protocol: - Different from the N-frame backward protocol, when the receiver receives an out-of-order frame, it will not discard all subsequent frames like the N-frame backward protocol. Instead, it will buffer the correctly received out-of-order frame. When the sender found that a frame was lost, it only retransmitted the lost frame, instead of retransmitting the subsequent N frames from the lost frame like the backward N frames protocol. This could avoid unnecessary data retransmissions and improve transmission efficiency, especially in a poor network environment with a high packet loss rate. Both of these two types of protocol were designed to deal with the loss of frames and the disorder of order during data transmission to improve the reliability and efficiency of data transmission. However, the specific ways in which they dealt with the problem were different. "Choose" was equally exciting. Everyone was welcome to read it!
