Computer network gbt protocol
The GGN (Go-Back- N) protocol was also known as the N-step back-off protocol or the sliding-window protocol. It was a method of flow control. In the GGN protocol, the sender is allowed to send multiple packets without waiting for acknowledgment, but the number of unacknowledged packets in the pipeline cannot exceed a certain maximum number N. The sender must respond to three types of events: 1. When the upper layer calls rdt_send(), the sender first checks whether the sending window is full (i.e., whether there are N sent but unacknowledged packets). If the window is not full, a packet is generated and sent, and the corresponding variables are updated at the same time; if the window is full, the sender will return the data to the upper layer (in actual implementation, the data may be stored in a buffer or a synchronization mechanism is used. The upper layer can only call rdt_send() when the window is full). 2. Receiving an acknowledgment: The GGN protocol uses a cumulative acknowledgment for the acknowledgment of the packet with sequence number n, which indicates that the receiver has correctly received all the packets before and including sequence number n. 3. Time-out event: The name of the protocol,"N steps back", comes from the behavior of the sender when there is a packet loss or a long delay. Like the stop-and-wait protocol, timers are used to recover data or to confirm the loss of packets. If there is a time out, the sender will resend all the packets that have been sent but not acknowledged. The GGN protocol was an error recovery method that used the pipeline technology to solve the problem of the low utilization rate of the traditional MDT protocol. It was different from the selective repeat protocol. "Choose" was equally exciting. Everyone was welcome to read it!
Computer network sl protocol
The Spectral Repeat protocol was a reliable data transmission protocol in the computer network transmission layer. It was a pipeline mechanism and sliding window protocol. In the SP protocol, the sender and receiver had their own windows. Different from the GGN protocol (Go-Back- N protocol), the GGN protocol had a cumulative acknowledgment. Once an error occurred, all the frames after the error frame would be retransmitted. However, the SSR protocol returned to a single acknowledgment (one by one), and at the same time, it increased the receiving window (temporarily storing the frames after the error frame). It could receive the frames that arrived out of order and only resend the error frame. However, there were also some difficulties with the SSR protocol. For example, when the sender and receiver did not know the location of the other party's window (the window was not synchronized), there might be problems. For example, when the size of the sequence number space is 4 and the window size is 6 (2 to the power of k is (01), which is a K), it is possible that when the first packet is retransmitted and the fifth packet is sent, the receiver cannot distinguish between these two situations and will make an error. For the retransmission of the first packet, the receiver may mistakenly think that the fourth packet is saved instead of resending an ACK0. "Choose" was equally exciting.

The computer is unable to access the Phoenix Network
If there is a situation where the computer cannot access the Phoenix Network, it may be due to one of the following reasons: 1. The server of Phoenix Network is under maintenance or update, resulting in an access failure. 2. There was a problem with the domain name resolution of the Phoenix website, resulting in a failed access. 3.Phoenix Network's network security policy has been updated, resulting in access failure. 4. There was a problem with the computer network connection, causing the access to fail. If you can't access the Phoenix Network, you can try the following methods: 1 Wait for the server maintenance or update to complete before attempting to access. 2. Check the resolution of the domain name to ensure that it is correct. 3 Check the network connection status to ensure that the network connection is normal. 4. Contact Phoenix Customer Service for help in solving the problem. I hope the above answers will be helpful.

Qidian Chinese Network Computer Version
The Qidian Chinese website was a platform for reading many types of novels, such as fantasy, martial arts, original, online games, urban, romance, history, military, science fiction, horror, officialdom, transmigration, rebirth, and other novels. It had made many important contributions in the development of online literature, such as the first VIP fee system for online literature, the establishment of electronic publishing payment and content management systems, the introduction of the author welfare system, the establishment of the "Platinum Author" and "Great God Author" system, etc. These measures laid the foundation for the commerce of online literature, the professionalism of writers, and the branding operation. In terms of product form, it used the " library " model to replace the BBS-based model, bringing great convenience to authors and readers.

Four Development Paths of Computer Network
The evolution of computer networks could be summarized into the following four stages: 1. The embryonic stage of the network: From the mid-1950s, a remote online system centered on a single computer formed a terminal-oriented computer network. This was the first generation of computer networks. 2. The primary stage of the network: From the mid-1960s, the mainframe was interconnected. Multiple independent main computers were interconnected through wires to form a computer network, but there was no network operating system, just a communication network. In the late 1960s, the ARPan net appeared, which was the second generation computer network. 3. Generation stage of the ether network: From the 1970s to the mid-1980s, the ether network was produced. The network interconnected standard, the OSI, was established by the international standards organization. The world had a unified network architecture. The computer network that followed the international standardized protocol developed rapidly. The computer network at this stage was called the third generation computer network. 4. " The stage of the intelligent multi-media network: Since the mid-1990s, computer networks have been developing at a high speed. At the same time, the intelligent multi-media network has appeared. Now, it is the fourth generation of computer networks. It is a multi-media intelligent network with a transmission rate of one kilometer."
