First, introduce what is ALSA;Advanced Linux Sound architecture abbreviation for ALSA, translated into Chinese means the Advanced Linux sound architecture (this is Google translation); when it comes to architecture, it's a bit too much, so ALSA not only includes support and drive for sound cards;ALSA has the following characteristics:1, the efficient support of all audio interfaces, from ordinary users of the sound card to the Professional level multi-channel audio equipment;2, sound card driver

, the fewer bugs, the more powerful--which is already the consensus of all users, after a 18-version evolution, 7 years of temper, the OpenStack R version has a more mature framework, more stable functionality.The R version, compared to the Q version, focuses on enhancing the core compute (NOVA), Storage (Cinder), and dispatch container modules (Zun), and fixes some flaws in compute (NOVA), Storage (Cinder), and Network (Neutron). In general, the R version has a more stable core function than th

If you miss mirantis's webcast (early morning), you can only mine your own information. The following are only personal translations and understandings, and the correctness is not guaranteed. Correct the error. NOVA: Added support for NFV. This is very important to the open NFV project, opnfv.org. NUMA seems to be a key optimization object. High-end servers, such as Xeon QPI, are all NUMA architect

of data center resource utilization. For mobile, equipment usage is also relatively high when there are many data centers. Therefore, traditional data centers may be transformed during edge data center research, it is more out of consideration for future business development. China Unicom Currently, China Unicom released the "China Unicom Edge-Cloud Platform Architecture and Industrial Ecosystem White Paper" in February 27 this year. it announced the official launch of Edge-Cloud scale pilots a

exist, and network devices are simply connected to each other to form a tree-like network structure. The configuration of network devices is simplified and unified, and the keyboard experts who operate on network devices at high speed are no longer needed. There is no need for complex connections between network devices. Everything is done by the various configurations issued by the Controller. In this case, the network relies on SDN and NFV. SDN is

5G network slicing advantages and challenges The fifth generation of mobile communication systems, referred to as 5 GB, refers to the fifth generation of mobile communication technology, which is also an extension after 4G. As of November 2017, 3GPP released the first 5g empty port (NR) standard. 5g pre-commercialization is expected in 2018 and 5g pre-commercialization in 2019. The International Telecommunication Union (ITU) will become the standard organization for the final release of standar

ViewSDNthere might be a clearer way of thinking,don ' t wait, worth reading. 7. SDN and NFV? author @ kkblue , with " for the human secluded couplets, the language is not surprising death endlessly " This sentence to describe kkblue God's style of personal feeling is more appropriate, perhaps the master is so, can be esoteric technical problems with such humorous words expressed, perhaps as Kk said , " tangled in the concept, Just the primary stage

internal cloud environment, public cloud, or private cloud environment. There are various network devices on the market, from Server Load balancer and application delivery controllers to application acceleration, encryption, or cloud bridge devices. The migration from virtual network functions to Virtual Devices indicates that we will move more to network function Virtualization (NFV). NFV advocates that a

Center, for example, unified scheduling across the world, enable network functions to run in the most urgent places to ensure performance, or to run in the most cost-effective place. With such features and ideas, cloud computing is no longer a "Never quenching thirst" for telecom networks, but a "first month of near-water buildings ". Let's take a closer look at the mysteries of Wind River Open Virtualization alization Profile. Open Virtualization Profile is designed to minimize latency and pro

the scheduler becomes a performance bottleneck; Ha is known as a highly available cluster, where MTBF (mean time to failure) and MTTR (mean time to repair) and availability=mtbf/(MTBF+MTTR) are the concept, and once we tend to make MTTR time 0, Cluster high availability will be good, for different business, the availability requirements are different, generally reduce mttr to improve availability; HP is called a high-performance cluster, centralizing the computing power of multiple servers to c

root, running/usr/sbin/sndconfig; 2 from the sound card selection list to choose the right sound card, the general sound card can use SoundBlaster; 3 after the election, Sndconfig need you to set up your sound card IO address and IRQ interrupt number, according to your actual choice; 4 The setting is done by pressing the OK button, if you hear the sound of Linus speaking. 39.

module (either a single file or a file module in a package) or as a method name for an as rename import.Package Benefits: Whether through the import or from module (method) is the search path in the Sys.path to find, or the program runs the current directory. This search is linear, so if you have two module names, you cannot import both of the methods in the same name module.Learned about the difference between package and module and import and from use. It is very helpful for us to see the sou

In the previous blog, a Linux server cluster with LVS-DR mode was deployed, and the use of it was described in this blog post, and the experiment was done by deploying WordPress in the cluster.First, the deployment of experimental environmentFirst deploy the cluster, you can refer to the previous blog post deployment Lvs-dr method Deployment LVS-DR cluster: http://11142243.blog.51cto.com/11132243/1974868Then, because WordPress uses the database, and here we need to ensure that regardless of whic
