ip internet protocol

I believe you have some knowledge about this aspect through some column-based TCP IP protocol learning. In our computer, there are also operations related to this Protocol. Now let's introduce how to reset the tcp ip protocol. This operation is risky, so you must consider it

the packet, and if it is set, the destination IP address of the test datagram is the same as the native IP address, and if not, an ICMP error message is sent. Sends an ICMP Redirect message (next article share) to the source side. Subtract the TTL value by 1 Handling IP Header Options Perform an IP sha

network, network interconnection devices are often located in the next three layers, hardware and software to achieve the way. The fifth to seventh layers of the OSI reference model are called high-level (upper layer) and several layers (host layer), which are used to ensure the correct transmission of data and are implemented in software mode.OSI Layer Seven features:TCP/IP protocol stackBecause the OSI m

Assuming the username is admin, password 123456, the configuration process is as follows:This case is XX Telecom ADSL PPPoE access, need to use a common ADSL modem and a Cisco 2600 router (dual Ethernet port), IOS 12.2 (), can realize LAN sharing Internet.　　This case configuration is divided i

TCP IP tieringThe TCP IP protocol is divided into four tiers and each layer is responsible for different communication functions.Data Link layer: Refers to the network interface and driveNetwork layer: Information in the network transmission, the pro

When it comes to networks, its development significance is actually very simple. A single link for multiple local networks, that is, isolated island communications. Gradually expands to form the Internet we are currently using. It is also an idea of information sharing. Now let's talk about the relevant content of the tcp ip protocol component. Suppose we have tw

(2) The disadvantages of the seven layer protocol included in the OSI: ① is more complex to implement, according to the seven-tier development of the actual network structure, the operating efficiency is relatively low; ② Seven layer protocol is not strictly divided, there are some functions in the layer between the duplication phenomenon. (ii) TCP/

For the Internet, various protocols are used to regulate its usage, so that this large and complex network can work in an orderly manner. In this protocol structure, the tcp ip protocol family is the foundation. What protocols are included in this structure? In order to allow readers to fully understand some basic netw

Chapter 11. about layering: TCP/IP protocol is divided into four layers: link layer, network layer, transport layer, and application layer; the layer-2 switches, layer-3 switches, and layer-2 networks we usually call follow the OSI (Open System Interconnection) layer-7 network model. In TCP/IP protocol, an application

The protocol addressing mechanism mentioned above is simple, the transmission speed is slow, it is not suitable for the data transmission of large range and large flow, therefore, it is applied to the interior of the equipment (such as IC, between circuit board and Circuit board). The TCP/IP protocol stack physical layer uses the fiber/coaxial cable for the trans

If your computer IP address is the same as the IP address of the other computer in the local area network, a conflict will occur. Today deep XP system download station and you talk about IP issues, and how to set the Windows7 IPV6 protocol. Does every computer need to have IP
