Before network device registration and NIC initialization are available, the associated net_device data structure must be initialized and added to the kernel Network Device database,Configure and enable. It is important not to confuse

There are many ways to build high network availability, such:1. server clusters include LB: Server Load balancer cluster HA: high availability cluster 2. router device HSRP: hot backup routing protocol VRRP: vro redundancy protocol 3. linux Network

1. The protocol name corresponds to the device data packet name. The application layer http ftp transport layer TCP/UDP segment network layer IP router data packet datasyncTransmission reliability is not guaranteed. The upper layer protocol provides

Objective: To understand the experiment environment for running the OSPF protocol on a Cisco Route: the two routers are used to simulate the two LAN networks 192.168.1.0 and 192.168.3.0. the topology of the two LAN networks that can communicate with

OSPF is a link State Routing Protocol Based on SPF algorithms.Under www.2cto.com, Ma summarized the detailed work process of this agreement and hoped to help you ......When a new router is added to an OSPF area, the OSPF protocol is working. If you

The OSPF on the broadcast Multi-Channel Access link starts the OSPF process on each device on the broadcast Multi-Channel Access link according to the parameters in. Here, I only use R1 as an example to describe how to enable the OSPF process:

TCP is a connection-oriented protocol. Before sending data to the other party, a connection must be established between the two parties. This section describes in detail how a TCP connection is established and how it is terminated after the

The three-way handshake mechanism of TCP connection TCP is connection-oriented. The so-called connection-oriented mechanism means that a connection must be established before data transmission when both parties communicate with each other, finally,

The 64-bit pre-sync code (reamble) and start frame delimiter (start frame delimiter) at the beginning of the structure of an ip address ). The pre-sync code is used to ensure that the data exchange between the sender and the receiver is the same as

The visual understanding of the STP protocol is still the same. When learning a protocol, we should first find out what the problem is, that is, the Protocol is designed to solve what problems meet what needs, then try to implement it in your mind.

IPv6 learning notes IPv6 changes are reflected in the following five important aspects: 1. Extended address. 2. simplified the Header Format. 3. Enhanced support for wide expansion and options. 4. Stream tag. 5. authentication and confidentiality.

If you understand the ACL, you cannot solve the problem of wildcard mask and wildcard mask. To put it simply, the wildcard mask means that 0 is an absolute match and must be strictly matched, while 1 is an arbitrary one. In a sense, if an 8-bit has

Using the ping command to detect the network layer protocol and hardware ping command is a basic network test command, which supports echo protocol, echo protocol checks network connectivity by testing packets forwarded by routers. During the test

This section describes link layer.In the TCP/IP protocol family, the link layer has three main objectives: (1) sending and receiving IP datagram for the IP module;(2) send ARP requests to the ARP module and receive ARP responses; (3) Send RARP

In a storage system, to increase the throughput of backend devices, the multi-nic binding technology is often required. For example, the backend storage can provide a maximum throughput of 300 MB/S. Therefore, you need to use 3 1 GPS NICs for

Understanding of the IP packet header validation field the IP packet format and the first field:Www.2cto.comThe data items in the table above are not explained in detail. Here we focus on the following data items:1. 4-bit Header Length: The length

Spanning Tree [02] detailed explanation of RSTP principles and configuration instancesWhy do we need to use RSTP and RSTP? in the previous article, we learned the operation principle of STP. When the topology in the STP network changes, the switch

Analysis of TCP three-way handshake processTCP (Transmission Control Protocol) Transmission Control ProtocolTCP is the transmission control protocol used by the host to control the host layer. It provides reliable connection services and uses three

TCP/IP explanation: the IP protocol ARP protocol and RARP protocol put the three Protocols together for learning because the three protocols are on the same layer. ARP is used to find the Mac address of the Ethernet NIC of the target host, the IP

Briefly describe the layer-4 architecture of TCP/IP and the role of each layer. data Link Layer 2. network Layer 3. transport Layer 4. the application layer, where IP is in the Layer 2 network layer, TCP is in the layer 3rd transport layer, the most
