SDN's no-layer network and TCP/IP layered network are now being swallowed up. What I'm talking about is whale swallow, rather than eating away! TCP/IP is still safe today, but external threats are approaching, and the interior is also collapsing! During the call to the Republic of siserro, Gaius. caesar has passed through the lubikong River with a clear vision. At the moment of the defeat of Brutus Phillips, the siserro faction was actually unable to return to heaven. these seem to be the strugg

Industry trends,snd is the future. P4 is the future. SDN is inevitably, and P4 is inevitably.P4 = Programming Protocol-independent Packet ProcessorsOfficial website (org):Http://www.p4.org/index.htmlP4 paper:Http://arxiv.org/pdf/1312.1719.pdfAbstract (abstract)P4 is a high-level language for programming protocol-independent packet processors.P4 is a high-level language used for protocol-independent network packet processor programming.P4 works in conj

As we move firmly towards the Sdn world, it becomes increasingly obvious that in the SDN world, engineers need to learn more skills, including the SDN programming language. Of course, it's great to be able to master every programming language, but in fact most people may not have that much time and interest to learn each language. Then there are three major

The previous article focused on the SDN Controller Test topic four : Floodlight test Report for South-to-North interface ( bottom ) , the function test results of the controller are given. This article will test the floodlight controller According to the determined performance test item, and give the test result. 1 Purpose of testingVerify The following performance scenarios for the Floodlight v1.0 controller:Verify the maximum size of the controlle

Developing solutions that implement software-defined networking (SDN) and network function virtualization (NFV) remain a major challenge for enterprise and Communications Service providers (CSPs). The rapid evolution of standards and open source software for network nodes, network control, and network orchestration poses a burden for organizations that are evaluating how to implement a new generation of networks.Intel? is a leading founder and contrib

Note: The basic idea of this paper comes from the thesis, introduces a kind of method similar to Sdn OpenFlow, and applies it to the FCoE network. This method of control flow can coexist with the SDN flow control method OpenFlow protocol, but it is not exactly the same as the data plane and control plane extending the OpenFlow protocol:)Problemintegration of storage networks into virtual networksBecause dat

How does android combine SDN numbers in the phone book with other common numbers?The original default design will separate SDN with the title "SDN ",The following modifications can be used to arrange the SDN and general numbers in the same order and in the first order.In configureSelection () method of DefaultContactLi

Platform Environment Description:Cpu:Intel Core 2 Duo T6570Mem:4.00GBOs :Ubuntu 14.041.FloodlightFloodlight is a relatively mature SDN controller implementation, in which the opendaylight Project also uses many of its implementation methods, the official website: http://www.projectfloodlight.org/floodlight/. in this paper, we use it as a controller, using virtual machine with mininet as network topology, which combines analog display network. Floodlig

Recently has been learning Ryu controller, in the process of use, found the following aspects of the advantages: Ryu controller is written in Python language, in the understanding and speed is very fast; The Ryu controller's overall architecture is clear, In the future, I will organize an architectural article about the Ryu controller for your reference; The Ryu controller itself is a powerful network experimental platform that is very well compatible with OpenStack and is not very familiar to O

Does Facebook switch and sdn OS change the network? On July 6, June this year, Facebook announced that it was preparing to open source its SDN switch operating system FBOOS forward proxy and its hardware receiver switch Wedge. Most people know that very large-scale operators have quietly deployed bare metal switch hardware and will install SDN operating systems

How DCN and SDN meet new requirements New Technology of ip ran Network The traditional 3G/B3G network needs the basic bearer network to provide the Layer 2 capability to meet the needs of the Upper-layer network mobile service return. However, due to the introduction of S1-Flex and X2 interface, the basic bearer network must have three-layer switching capabilities. Based on the dynamic IP/MPLS protocol and key technologies, the ip ran is a solution t

SDN (Software Defined Networking) SDN is not equal to OpenFlow, its relationship is similar to the Internet is not equal to IP protocol, PSTN is not equal to 7th signaling, IMS does not equal to the sip,web system is not equal to the HTTP protocol. OpenFlow is only the SDN controller control forwarding Surface Equipment protocol, the controller's own architecture

What binds SDN/NFV applications ?, Binding sdnnfv applications According to a report, network virtualization efforts led by Software Defined Network (SDN) and network function Virtualization (NFV) are due to skills shortage and organization/Operation Problems, the technical advantages of multi-vendor integration have not been maximized. This is some of the main findings from Cartesian's report "The Future

In recent years, Linux-led open source projects in the IT industry, the emergence of a lot of good open source projects. Now everyone is talking about open source, after just understand the software open source, and heard the hardware open source, as if now do not say open source is not enough bigge. So, why open source? There is also an open-source boom in the field of networking, and today we're going to go around Sdn, NFV, and what we've done with

Zookeeper Container cloud is coming! The network scale of container cloud will be 10-times larger than that of Virtual Machine cloud. The interconnection requirements between container cloud and Virtual Machine cloud will also increase the complexity of cloud network management and control several times. The SDN industry is facing unprecedented challenges! This report shares the SDN Technology of Alibaba C

SDN can take you to a place where the existing network is not there, but you may want to reconsider forwarding the post. SDN is considered as the main way for enterprises to realize full virtualization network, and even the main way to realize full virtual data center. One of the main benefits of all of these virtualization is scale. Without hardware limitations, the
