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!
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!
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!
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!
An architecture that was designed to provide security services in a hybrid application of both the IPv4 and IPv6 networks. It provides confidentiality and integrity by encryption of the data to be protected and placing the encrypted data in its data portion. It uses a symmetrical key encryption algorithm to provide data integrity verification, data source verification, and anti-replay attack services. Depending on the user's security requirements, it can be used to encrypted the transmission layer (such as IP, IP, IGMP), or it can be used to encrypted the entire IP packet. Encapsulated protected data was necessary to provide confidentiality for the entire raw data report. The EP header can be placed after the IP header, before the upper layer protocol header (in the transport layer mode), or before the encapsulated IP header (in the tunnel mode). The protocol value assigned by Ivana to the EP header is 50. The protocol header before the EP header will contain the value 50 in the "next head" field of the IP version 6 or the "protocol" field of the IP version 4. The ESP contains a non-encrypted protocol header followed by encrypted data. The encrypted data covers the protected ESP header field and protected user data. The user data can be the entire IP datagrams or the upper layer protocol frame of the IP (for example, the protocol of a protocol such as a protocol or a protocol such as a protocol. In addition, the set of services provided by the EP is determined by the options selected and the arrangement of the implementation when the secure connection (Sa) is established. The confidentiality option is independent of other services, but using the confidentiality service without the integrity/authentication service (in the EP or in AH alone) may cause the transmission to be subject to some form of attack and destroy the confidentiality service. Data source verification and integrity of the non-connection are related services, provided to the user in combination with confidentiality (option). The anti-replay service can only be selected when the data source verification is selected, and the receiver can decide the choice of the anti-replay service alone.

Transcendence Logic was a type of circuit logic that was mainly used to control the input and output signals of computer circuits. When the circuit input receives a high-level signal, the TTL will send a low-level signal to the circuit output. It can be used to implement a variety of circuit controls, such as gate circuits, shift register, counters, and clock circuits. The standard of the TTL level was that +5V was equivalent to a logic " 1 ", and 0V was equivalent to a logic " 0 ". This method of data communication and level regulation was called the TTL signal system. Ordinary electronic devices used TTL, but some communication methods such as RS232, RS485, USB, etc. used differential signals on the transmission line. The TTL protocol is suitable for digital circuits and microchip systems, while the RS232 protocol is commonly used for computer serial communication and industrial automatic control systems. The input of a TTL circuit is usually in a high state when it is not connected because they usually have an internal pull up resistance. " Choose " was equally exciting.

I think 'novel protocol' could refer to a new or unique set of rules or procedures, especially in a specific context like science or technology.
I don't know the specific significance without more details. It could be significant within the context of the group or system that uses it. Maybe it represents a major breakthrough or a big change in the way things are done if it's related to a project or research.
The protocol that Novell developed for Netware is IPX/SPX. It played a crucial role in enabling reliable and fast data exchange within Netware-based networks. It had features tailored to the unique characteristics of Netware's architecture and functionality.
The Montreal Protocol is indeed a remarkable success story. It started as a response to the growing threat of ozone layer depletion. Scientists discovered that substances such as CFCs were causing a hole in the ozone layer. The Protocol then came into play. It required countries to take action to reduce the production and consumption of these harmful substances. Over time, strict regulations were implemented and monitored. As a result, the levels of ozone - depleting substances in the atmosphere have decreased. The ozone layer has started to show signs of recovery. This is a huge victory for environmental protection. It also serves as an example for future international environmental agreements, showing that with determination and cooperation, we can reverse the damage caused by human activities to the planet's vital systems.
