Introduction to TCP/IP network protocols
Some time ago I made a development, involving network programming, and the development process was quite smooth, but I always felt a bit confused after the task was completed. The main reason is that you are not familiar with network protoc
wireless network channels, which is a bit the same as normal mailing. If we do not encrypt the data files, we can directly transfer them in the wireless network, the wireless workstation around the local wireless network may intercept data files that do not adopt encryption protection measures, and the data files sent locally will leak the privacy information; i

Some time ago I made a development, involving network programming, and the development process was quite smooth, but I always felt a bit confused after the task was completed. The main reason is that you are not familiar with network protocols and are not clear about some concepts. Later, I spent some time learning about these
Network protocols are the foundation of the Internet. Therefore, we need to understand network protocols in many ways and from multiple perspectives. Because of the large number of network protocols, each protocol has its own func
Q: What are the NetBEUI and IPX/SPX TCP/IP protocols ?? In particular, the first two are sometimes installed, and sometimes they are not installed. Why ?? What are their differences and uniqueness? When must I install it?
A: A lot of netizens asked this question. I have consulted and integrated the relevant information here to give you a detailed explanation.
The network Protocol is a special software and t
The OSI seven-layer model is a standard system and framework for interconnection between different computers or communication systems, including a range of standards and protocols in OSI, such as TCP/IP, UDP, HTTP, and so on, which provide implementation and support for these protocols in Node.js, such as: NET modules provide TCP, Socket encapsulation and support, the Dgram module provides a package and sup
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
The common understanding of TCP/IP network protocols was developed some time ago. network programming was involved and the development process was smooth. However, after the task was completed, I always felt a bit confused. The main reason is that you are not familiar with network
Through understanding the computer network, its layer-7 structure has different protocols to regulate. Based on the network type, we can divide these protocols into LAN protocols and generalized network
Multicast routing is a good technology. It broadcasts data over the Internet. Unlike broadcast, due to broadcast storms, the router prohibits cross-route transmission of broadcast data. Multicast solves this problem. Currently, m$ software such as NetMeeting and WMS are widely used in multicast. Here we will discuss how to build your Linux into a multicast router.(Generally, gateways and routers do not support multicast data packets ).

Network Protocol in SQL Server
To connect to the SQL Server database engine, you must enable the network protocol. Microsoft SQL Server can process requests through multiple protocols at the same time. The client connects to SQL Server using a single protocol. If the clientProgramIf you do not know which Protocol SQL Server is listening for, you can configure t
The network routing protocol is essential in the network. As a protocol for address management and allocation, there are many types of protocols. Next we will summarize several important routing protocols for you to explain. Generally, there are two typical routing Methods: Static Routing and dynamic routing 。
Static R
backbone network, people connected to it through the IPIP (IP Encapsulation IP) tunnel. The Unix program mrouted can understand the DVMRP and IGMP protocols, but the Internet Router cannot. Many customers who want to adopt Multicast technology are still asking their ISP why some protocols do not work.
DVMRP refers to the distance vector multicast routing protoco
Switching Mode for resources, and the peer-to-peer bidirectional 64 kbit/s fixed bandwidth channel provided for both parties of the communication is not suitable for data services with large burst data volumes and large differences in upstream and downstream data traffic 。
The wide area network (WAN) protocol can be divided into DDN, X.25, frame relay, and IP network, because the IP
infrastructure or central device. In this system, all nodes can be moved randomly, and can maintain contact with other nodes, that is, each mobile node acts as both a router and a terminal at the same time. When two user terminals cannot communicate directly, communication is usually achieved by means of the routing function of other nodes 。
The routing protocol is the basis for communication between mobile nodes in the Ad-hoc network. It also direct
Network Layer 2 (IPv4 and IPv6 addresses and related protocols) IP (internet protocol) protocol is the core protocol of the TCP/IP protocol family and the network layer of the internet. The current version number is 4, also known as IPv4. The next generation IP protocol version number is 6, that is, IPv6. As described in the
package and send them back to the sender.
The system extracts data or commands and sends them back to the SCSI subsystem.
Security description:
The iSCSI protocol provides QoS and security features.
You can restrict the initiator to send a login request only to the target in the target list, and then confirm the request by the target and return the response.
Communication is allowed;
Encrypted data packets are transmitted through IPSec, including dat

2. Switch application processing to Open Systems (Windows and Unix)
3. IP addresses are widely used as interconnection protocols
None of these trends is surprising. Using the IP protocol, Intel-compatible open-system servers have dominated modern data centers. Given this dominant processing architecture, Ethernet Interconnection is a logical choice, and no other network
For various reasons, many networks adopt multi-route protocols. This phenomenon is usually caused by merger and acquisition activities, or temporary occurrence during the migration.
Many vro hardware manufacturers may use a variety of proprietary protocols to connect with standard protocols. Some routers will run more than one protocol and inevitably receive the
