the network, prompting the router to recalculate and change the route table accordingly. Dynamic Routing Algorithms can be supplemented by Static Routing where appropriate. For example, the last available route router of last resort) is used as the path for all non-route groups, ensuring that all data can be processed in at least one way.

I. Overview 1.1 Five-layer model The realization of the Internet, divided into several layers. Each layer has its own function, like a building, each layer is supported by the next layer. What the user touches is just the top layer, and there is no sense of the layer below. To understand the Internet, you must start from the bottom and understand the function of each layer. There are different models for layering, and some models are divided into seven layers and some four layers. I think it

scalability. In wireless 3G applications, BICC is in the Nc Interface of the 3GPPR4 circuit domain core network, and supports call connection between (G) mscservers. In a fixed network Softswitch application, BICC is in the call control layer of the layered architecture, providing support for call connection between different SoftSwitch. When the BICC architecture is adopted, all current functions can be kept unchanged, such as number and route analysis. The

the impact of BGP restart may be very far-reaching, BGP is an important object for High Availability improvement. BGP can carry a large number of routes. Therefore, the time for network convergence after a BGP software failure is usually longer than other routing protocols that support fewer routes. In addition, Because BGP is an Inter-Domain Routing Protocol, a

-direct connection network (for example, the next hop address of RouterB to the CIDR Block 172.16.1.0/24 is the s0/0 interface of router1. ). Note: ODR is not a routing protocol. The information exchanged by ODR is limited to IP prefix and default route. ODR does not report metric values. The default metric value for all routes reported by ODR is 1 hop. The route table of each branch router only contains its direct connection route entry and the ODR s

Among our commonly used devices, one is a router and the other is a switch. These two types of devices are all important for network management. So today we will give a brief introduction to the relevant content of the IP switch. These include GSMP and IFMP. To master the GSMP and IFMP protocols, we need to understand the concept of IP exchange. Next, let's take a look at the basic concepts of IP exchange. Basic concepts of IP address exchange IP exch

We use the Internet every day. Have you ever wondered how it is implemented? Billions of computers around the world are connected together and communicate with each other. One Network Card in Shanghai sends a signal, and the other network card in Los Angeles actually receives the signal. The two actually do not know the physical location of the other. Do you think this is amazing? The core of the Internet is a series of protocols, called Internet Prot

Currently, there are many kinds of router protocols. Today, I will explain the RIP, HELLO, and EGP technologies in the vro protocol. I will share them with you here, hoping they will be useful to you. Technically, the IGP Router Protocol is similar to RIP and HELLO. The router uses this vro protocol to obtain information about other vrouters in the autonomous system to update its route table. Unlike the internal Router Protocol, EGP also performs othe

narrowband voice services, supplementary services and data services. However, the BICC Softswitch protocol is complex, poor scalability. In wireless 3G applications, the BICC Softswitch protocol is in the Nc Interface of the core network of the 3GPPR4 circuit domain, and supports call connection between (G) mscservers. In a fixed network Softswitch application, BICC is in the call control layer of the layered architecture, providing support for call connection between different SoftSwitch. When

We know the excellent performance of IPV6 network protocol, and the most widely known is that it solves the problem of address resource depletion. However, it has other advantages in many ways. The following describes the security of IPV6 network protocols. I believe this is also a matter of concern to everyone. With the development of China's routing industry, the router technology is constantly updated an

XMPP and xmpp protocolsXMPP-instant messaging technology Overview (IM -- Instant Messaging) supports real-time online conversations. If you want to send a message, you need to open a small window so that users and their friends can enter the information and both parties can see that there are many IM systems in the conversation content, for example, AOL, Yahoo IM, MSN, and QQ, the biggest difference lies in the implementation of their respective communication

About I2C and SPI bus protocols Iicvs SPI Currently, in the low-end digital communication application field, we can see IIC (Inter-Integrated Circuit) and SPI (serial peripheral interface) everywhere. The reason is that these two communication protocols are very suitable for close-range and low-speed chip communication. Philips (for IIC) and Motorola (for Spi) have developed these two standard communication

Description of some network protocols DICT: a dictionary server protocol. Dict servers and clients use TCP port 2628 FILE: Mainly used to access files on local computers, just like opening a file in Windows Explorer. FTP: (File Transfer Protocol, FTP) is the Protocol for transferring files from two computers on the TCP/IP network. FTP is one of the earliest protocols used on the TCP/IP network and the INTER

IICVsSPIToday, in low-end digital communications applications, we are seen in IIC (inter-integrated circuit) and SPI (Serial peripheral Interface). The reason is that these two communication protocols are ideal for near- low-speed inter-chip communication. Philips (for IIC) and Motorola (for SPI) have developed both standard communication protocols for different backgrounds and market requirements.IIC was d

Introduction to TCP/IP and other network protocols 1. TCP/IP is a communication protocol for the Internet. Computer Communication Protocols are descriptions of the rules that computers must comply with in order to communicate with each other. TCP/IP refers to the Transmission Control Protocol/Internet Protocol (Transmission Control Protocol/Internet Protocol ). TCP/IP defines how electronic devices (such as

FCoE vs iSCSI After discussing the fusion mode, we can finally talk about whether to choose iSCSI or FCoE. The following are four main considerations: 1. Data center strategy, 2. Performance Requirements, 3. Compatibility goals, 4. Cost issues. In any situation, these four factors are very important for selecting FCoE or iSCSI, and the final decision can be made without any factors. In some cases, FCoE may be cheaper than iSCSI, and vice versa. Figure 6 multi-faceted SCSI No matter which protoc

The use of SAN multi-protocol is based on fiber channel. So what should I pay attention to when using some routes and switches for such optical fiber transmission? Next we will elaborate on this part. This great career of Kumar Malavalli originated from his comparison and Investigation of the world's popular network technologies represented by Ethernet and the channel technologies represented by SCSI ｡ He attempted to create an advanced network architecture based on the advantages of the network

Before the client computer connects to the database engine, the server must listen on the enabled network library and require the server network protocol to be enabled. The following settings can be made using SQL Server Configuration Manager. Enable the server protocol on which the SQL Server instance listens. Disables server protocols that are no longer needed. Specify or change each database engine, the IP address that will listen, TCP/IP ports,

the message as a response, as shown in the following figure. Each network application has its own application-layer protocol, which defines the format and sequence of messages exchanged between processes, as well as actions taken when sending or receiving messages. 　　Figure 1: Communication with each other should be with The application layer is a good place for us to start studying the agreement. We are already familiar with many applications that rely on
