digital unit (DU), RF unit (RU) and core network components all use dedicated devices provided by equipment vendors. For example: To achieve Network slicing, Network Function Virtualization (NFV) is a prerequisite. In essence, the so-called NFV is the hardware and software functions of dedicated equipment in the network (such as MME, S/P-GW and PCRF in the core network, the digital unit DU in the wireless access network, etc) transfer to a Virtual machine (VMs. These virtual hosts are commerci

I declare that this article does not involve any specific APIs or specific vendors, but it is worth noting that, the successes and failures of some acceleration board manufacturers are precisely due to their versatility. In this era where people are still dependent on professional boards, boards are still regarded as specialized problems, vendors that represent these boards and claim that they can solve common problems should be cautious! Although I am very optimistic about generic boards, I am

entrepreneur, you have the following advantages: Energy (stamina), poverty, rootlessness, and colleagues ), and the Ignorance (ignorance ). There is no doubt about the importance of being energetic. If you have heard of a startup company, you will have heard of timeout. This is a general rule. I can't imagine which successful startup company is working nine to five. For young entrepreneurs, timeout is even more necessary, because they may not be very efficient. Your second advantage is nothing.

that startups do not have customers at first, and they need to think carefully about all problems related to customers and their business models. Unless the company's founder is really an expert in a certain area and has many years of experience in the industry, the chance is very small. Entrepreneurs must admit that the so-called "clear customer needs" in the early stages of entrepreneurship are based on self-confidence guesses. To succeed, entrepre

Between 2004 and 2000, 75% of the startups that received VC investment finally failed. However, please do not leave the above data to encourage you to fail. There must be a reason. It may be because the developed products are not as good as you think, or the team wants to solve too many problems at the same time. The divergent result is to create a product that cannot solve anything, after all, focusing on development is very important. How can we avo

It reduces capital expenditure (90% in some cases) and operating costs, it also increases the capability of resource allocation and mobilizes services. It provides all the network services required by virtualized applications and places them on another virtual machine on the same server; applications do not need to leave the server, which reduces traffic and costs in the South and N

One article compares the methods mentioned in the existing research, and here records the types of methods and their shortcomings.

In my ip_conntrack version, it can cache routing and filter rules, and can also smoothly implement the nat with the latest configuration. It is more and more like a real SDN version, the only thing that needs to be improved is to evolve the tuple of the 5 tuples into the tuple of the N tuples, and the rest of the updates and corrections are quantitative changes that will not lead to qualitative changes. Now, what else can ip_conntrack cache? Of course

NFV needs to be commercially available on several fronts When talking about networks, there are two words that cannot be bypassed at all, namely SDN and NFV. SDN emphasizes the separation of forwarding and control. By introducing a new control plane, it shields details of forwarding plane from different manufacturers and realizes intelligent and centralized network control functions; NFV emphasizes the dec

Explanation of X.509 Certificate DN December 4 th, 2008 BySoloman || 823 views X.509 uses the DN (distinct name) to uniquely identify an object. Its function is similar to the ID we usually use. However, the difference is that the DN is no longer a digital identifier similar to 123456, multiple fields are used to identify an object, such as "cn =, c = cn". The advantage of this is that it is convenient to match to directory services such as LDAP. Can the DN field be added at will? For example,

Startups are usually dynamic, looking for scalable, reusable business models. On the way forward, startups need more reliable partners and stronger investors, enough to take ideas and ideas to the roots and thrive. And now, with the help of the Internet, such enterprises are more and more, involved in the field and industry are also different. Some of these startups
