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

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
This tutorial is based on the Ubuntu12.04 edition, and it will help readers build a openstack minimized installation. I am the top of the Wuyue, translation more use of transliteration method, so the individual words and the original discrepancy, please understand. I am not a major in English, I think the most important thing is to understand the technology, and not the four level and grind in the boring English-Chinese translation, so my goal is loya

In fact, the project presented by the Huawei Israel technical team is still
In the SDN standard system developed by ONF, in addition to OpenFlow switch specification pairs, there is also a Protocol named OpenFlow Configuration and Management Protocol (OF-CONFIG) also needs to be concerned. As mentioned above, OpenFlow defines a kind of southbound interface in SDN network architecture, and proposes a method for the Controller to send a flow table to the OpenFlow switch to control th
The construction of SDN competition environment and the realization of the first major problemDue to the lack of physical equipment, the virtual machine to implement the Floodlight controller, Openvswitch (hereinafter referred to as: OVS) and mininet all kinds of SDN environment to be used to build. The following will give their construction steps and then use Mininet simulation to give the challenge of the

The majority of attacks are blocked by the access control system established for a particular network segment and service before reaching the target of the attack. Second, Experiment

UOS public cloud has these advantages mainly because it has an efficient underlying technology platform. For example, UOS uses SDN technology to build a virtual data center (VDC). You can quickly obtain the resources required by the data center within one minute through APIS or the console. For another example, unitedstack developed the UOS block storage service using distributed storage technology to pro

Ryu Topology Discovery principleOpenFlow's official does not prescribe a standard topology discovery method, now OFDP (OpenFlow Discovery Protocol) is still using the Link Discovery Protocol LLDP in the traditional network, and then introduces Ryu how to use LLDP to discover the topology, Suppose there are now two OpenFlow switches connected to the
first, the basic knowledge of OpenStackOpenStack is a free software and open source project that was developed and initiated by NASA and Rackspace to Apache2.0 licenses (compatible with GPLv3 and DFSG).OpenStack is an open source cloud computing management Platform project, composed of several major components to accomplish specific tasks. OpenStack supports almost all types of cloud environments, and the p
As a core tutorial for OpenStack, we have come to the final summary.
OpenStack currently has dozens of modules, this tutorial discusses the most important core modules: Keystone,nova,glance,cinder and neutron. Please look at the following figure:

From the above process can be seen, the network function from the Folsom version began to introduce, experienced the Folsom, Grizzly, Havana, Icehouse Four versions to form a more stable centralized network model. The distributed routing mode
It may be useful to use ABAP to schedule jobs in other systems asynchronously. The principle is similar to scheduling event on R3 on BW side,
The event returns a successful or failed status to the BW process chain.
The detailed process in the following section is derived from Sdn.
You can create a job in R/3 to be triggered "after event". Then in your process chain, you create an ABAP process:
Call mode: asynchronous
