What exactly is SDN? Although the concept has been fired for many years, no one has yet given a clear idea of it. On the internet also emerged a lot of excellent articles on SDN thinking, adhering to the "do high-quality content porter" idea,Sdnlab June collected some of the following articles to share with you.

SDN changes the router technology development path, and sdn changes the router path Over the past 30 years, IP networks centered on routers and switches have always followed Moore's Law to build a modern information civilization with other IT devices. As the core device at the WAN and LAN egress, routers have always played a key role and have undergone continuous development and numerous upgrades. Today, t

, but you need to design, install, run, manage, maintain, serve and support this infrastructure on your own. Unless you choose to purchase from a vendor such as Dell and Cumulus. 8) Check out the start-up products: Cumulus is a startup company that advocates open-source and white-label products, including Linux operating systems dedicated to networks that can run on bare metal switches. This is expected to significantly reduce the cost of the data center network, and through the Dell partnership

in the SDN architecture. The network operating system and upper-layer applications constitute a control layer. The data forwarding and control layers are decoupled using a standardized interaction protocol, which is currently OpenFlow. This decoupling architecture indicates that network operating systems and network applications (such as routing control protocols) do not have to run on physical devices, bu

Relationship between SDN and intention-Based Network (IBN), and sdn intention Network (ibn) Compared with SDN, the intention-Based Network (IBN) is somewhat immature. Although it is also a technology that changes the network industry, what is the relationship between the two? SDN and intention-based networks are simil

Real-Time Route Selection and computing, operators need to be able to provide real-time full-network views and deploy and transmit resources as needed, however, these multi-layer full-network views and control capabilities cannot be implemented for various reasons today. Transmission Networks optimized for cloud services To carry cloud services, carriers need a multi-layer SDN architecture to divide the network into two main components: the network v

all, the former collection access network used the same tdm/msap technology. System vendors develop a set of TDM products can be sold to all operators. However, the new group-based set of guest access networks will vary by operator. Different carriers use different packet switching techniques, such as PTN Span style= "font-family:arial" >ipran , carrier-grade Ethernet, etc. System vendors will not be able to afford to develop different access devices for different operators. Second,

power and capacity to a level that exceeds any senior administrator. It also controls the status of network logs. However, the problem is not so bad, but enterprises need to consider the impact of SDN security belt, or worse, the zero-day vulnerability exploitation. One of the reasons why Stuxnet is so hard to create is the various challenges it needs to overcome. It needs to respond to multiple versions of proprietary industrial controllers and use

marathon, and subsequent academic papers and white papers. SDN is an important pillar of the Network architecture. The same is true for Network Function Virtualization (NFV. As more open and interoperable infrastructure and solutions are quickly adopted, we will also see the emergence of multiple platforms and communities based on these architectures. In this transformation of the Internet, SDN is obviousl

The control layer is the SDN brain. It is responsible for centralized and unified control of underlying forwarding devices and provides interfaces for calling network capabilities for upstream services. It plays an important role in the SDN architecture, SDN controller is also the focus of SDN. In terms of technical im

API that sends streaming data to the switch, and netconf is the network Settings API.) ) SDN: Basic Architecture In the current SDN approach, the vendor provides applications and a single controller in one product. For example, Nicira/vmware encapsulates its applications and controllers in a single proprietary application stack. Cisco will embed the controller in the iOS software on the device, thereby e

that NFV and SDN will be used to support different RAN and different business types running on these RAN. In addition, the commercial introduction of SDN and NFV is expected to grow significantly over the next few years, so that network Slicing can provide flexible network installation to meet the needs of various applications and services. In addition, SDN can

specific mode and set the threshold value of data packet capacity from one or more sources within a specific period of time. These switches can then discard the data packet or redirect it to another destination using other technologies and protocols. Most routers and other network platforms do not have such a detailed control mechanism. 2. Attacks against specific applications and services: these attacks only target Web services with very special HTT

For example, nicira/vmware encapsulates its applications and controllers in a single proprietary application stack. Cisco will embed the controller into the IOS software on the device to encapsulate its controller into the onepk product. Big Switch Networks recently released a commercial version of SDN controller, whic

SDN is the most popular technology concept nowadays. As the core component of the future network architecture, SDN controller is still evolving in the future. For enterprises, what functions and attributes do SDN controllers need to know in advance? The following are 10 functional standards that enterprises need to consider when selecting an

SDN promotes vro Technology Revolution Over the past 30 years, IP networks centered on routers and switches have always followed Moore's Law to build a modern information civilization with other IT devices. As the core device at the WAN and LAN egress, routers have always played a key role and have undergone continuous development and numerous upgrades. Today, the router interfaces have changed from a wide variety of narrow-band interfaces, such as X

Editor's note: Sdn-ip is an application on Onos that allows software-defined networks to connect to external networks using standard Border Gateway Protocol (BGP). From a BGP perspective, the SDN network behaves as a single autonomous system (as), with the same behavior as any traditional as. The SDN-IP application based on as provides an integrated integration m

Tame your WAN: Apply SDN to the WAN and wansdn The network should have responded to the needs of users and applications. However, for a long time, the network does not meet our needs well, and the network forces users and applications to adapt to network restrictions. In enterprises, the IT department has been striving to ensure that the network security capability is consistent with the development of devices and applications. In the WAN, bandwidth

As a new network architecture, SDN has become a hot topic in the industry. The open network it advocates represents a change in the concept of network construction from adapting network capabilities to actively adapting network capabilities to the needs of network applications. Separation of forwarding and control, centralized control, and open network programming interfaces are the main features of SDN net
