Docker cluster network planning and VM network configuration
"Summary" using either k8s (kubernetes) or Docker swarm requires a cluster of PCs or VMS, and network planning is the first step to starting a job. The goal of this article is to use VirtualBox on a stand-alone computer to create a CentOS 7 server cluster, especially the basics of
in Linux, the network is divided into two tiers, namely the Network Stack protocol support layer, and the device driver layer that receives and sends the network protocol. Network stack is a separate part of hardware, mainly used to support TCP/IP and other protocols, the network
Today more and more products to join wireless this huge family, notebooks, mobile phones, cameras, projectors and other equipment become a daily essential office and communication equipment, but also by virtue of the characteristics of strong mobility, so that many people more dependent on wireless internet. Now the use of wireless network is not limited to one floor, many office buildings, luxury hotels, large shopping malls and individual villas are
leverages its industry-leading GPON technology to push fiber-optic access networks to the most economical and efficient areas and fully tap into the value of existing networks, multiply the competitiveness of new networks to meet the needs of operators' FTTx application scenarios and help them achieve the most economical improvement of optical fibers, alcatel-Lucent's 7342ISAMFTTU can integrate voice, video, and data services into a single optical fiber and support a downlink rate of 2.5 Gbit/s
This series of articles summarizes Linux network stacks, including:(1) Linux Network protocol Stack Summary(2) Network multipart offload technology Gso/tso/ufo/lro/gro in non-virtualized Linux environment(3) QEMU/KVM Network multipart offload technology in virtualized Linux environment Gso/tso/ufo/lro/gro1.

As a large game, it is unavoidable to use complex interfaces, network message processing, data caching and other slightly complex things. In fact, we all know that for a hand tour, the huge system engineering below, is actually a lot of basic technology stack. Therefore, in the game development, the emergence of various types of bugs is not because of technical implementation problems, but from the framework, code management of the design errors appea

This paper introduces the deep convolution neural network based on residual network, residual Networks (resnets).Theoretically, the more neural network layers, the more complex model functions can be represented. CNN can extract the features of low/mid/high-level, the more layers of the network, the riche
First, prefaceAfter a period of accumulation, for the neural network, has basically mastered the Perceptron, BP algorithm and its improvement, Adaline and so on the most simple and basic knowledge of feedforward neural network, the following is based on the feedback neural network hopfiled neural network. Feedforward n
1. From level two IP address to level three IP address:* * Level Two IP address design unreasonable:The utilization of ①IP address space is sometimes very low;② assigns a network number to each physical network, which causes the routing table to become too large and thus causes the network performance to become worse;③ level Two IP address is not flexible;2. subn
Many win7 system users create LANs to share resources. When we visit, generally through the sharing of the way to the local area network computer access, operation, storage. If we use the "Map Network Drive", we can access it easily. "Map Network Drive" is actually the local area network of the pastoral directory map o
The biggest problem with full-attached neural networks (Fully connected neural network) is that there are too many parameters for the full-connection layer. In addition to slowing down the calculation, it is easy to cause overfitting problems. Therefore, a more reasonable neural network structure is needed to effectively reduce the number of parameters in the neural net
In the rapid development of the Internet today, the network has become an indispensable part of our daily life. When you are surfing the Internet at the same time, your computer will inevitably have such a network failure, on the network, how to find these network failures? It's really a difficult problem for beginners
Linux mainly uses three types of network management commands: 1.ifconfig, route and Netstat belong to the traditional function of single-class network command; 2.ip and SS belong to the Integrated class Network command; The 3.NMCLI is suitable for comprehensive network commands in RHEL7, and can also be configured with
China's wireless access network is still widely used, and it is also very important to optimize the network. So I studied the GSM network optimization problem of the Wireless Access Network, I would like to share it with you here and hope it will be useful to you. With the development of the mobile communication indust
Testing tools are the means to achieve automated testing. The rational use of testing tools can not only improve the network diagnostic capability, but also facilitate network management. Generally, broadly speaking, network testing tools can be divided into physical cable tester, network operation simulation tool, pro
Enterprises are becoming more and more demanding on the network, in order to ensure the high availability of the network, sometimes want to provide equipment, modules and link redundancy in the network.
However, in the two-tier network, redundant links may lead to switching loops, allowing broadcast packets to cycle e
Today's two network structures are the latest in the industry for image processing problems proposed by the latest structure, the main solution is the Super deep network in training optimization problems encountered. To tell the truth, both models are not mathematically complex in themselves, but it does have a very good effect in combat (the deep residual network
Network faults are so strange. How can we effectively solve network faults and give a correct conclusion to the "healthy" Situation of the network? This article describes the network test based on the network hierarchy and network
