This provides a space for a large number of startups or open source organizations, who have developed a wide variety of network implementations and have not seen a single big state, but have a lot of complex solutions that customers can't pick.Some customers feel that SDN is good, the introduction of SDN concept into the container domain, the result of a more complex problem

This is not, we ushered in a choice question, that is in SDN/NFV of open-source controller level, the telecommunications industry will choose? is to choose it/the Internet world has been

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

HP and F5 are working together to implement an automated application distribution solution that supports Layer 2 to Layer 7 networks. So far, the cooperation results have been confirmed to support Microsoft Exchange, server virtualization and disaster recovery. This technology can help network engineering abandon the CLI), allow them to use

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

In fact, the project presented by the Huawei Israel technical team is still a subject of great interest to developers in the Internet sector. The Dragonflow project was submitted in 2014 and 2015, and has now be

Preface This period of time has been studying how to improve the utilization of flow tablespace. I have never been able to think of good idea. One article compares the methods mentioned in the existing research, and here records the types of methods and their shortcomings. These methods are not limitedHow to improve the utilization of flow tablespaceTo extend the scopeHow to improve the matching success rate of the vswitch flow table.Background Software Defined Network (

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,

I learned the ECC Elliptic curve algorithm and know what is called Double certificate authentication, but I think the most important thing for me is that I changed the logic of Linux Bridge in 2013, making it conform to the idea of SDN!What

Server virtualization is becoming more and more common, and many companies are trying to run their existing business in a virtualized way--virtual multiple instances on a physical server, each isolated from each other as if they were using a real host, and so is network virtualization. Several network environments are virtualized on the same physical link and isolated from each other; Network virtualization also breaks down traditional VLANs and IP address assignment, and using network virtualiz

On Monday, a small startup named contrail systems ended its secret investment phase and was formally established on Tuesday. Today, just two days after the company was formally established, the company was acquired by Juniper Networks for $0.176 billion. Contrail's founders, employees, and investors earned $57.5 million in cash, plus 6 million shares of Juniper Networks. For a company founded just two days ago, this price is already very good. Juniper has been eyeing contrail for a whil
