Introduction to docker openvswitch Network What isOpenvswich Openvswich network:BelongThird-party network project,It can be understood as a standard switch protocol. Openvswich: openvswitch is a multi-layer software switch based on the Open Source apache2.0 license. It manages multi-Tenancy cloud computing network environments and supports KVM, xen, and other Virtualization Technologies. The following functions are supported: 1.Supports the trunk and access port modes of t

public cloud services. Since the opening of public cloud services, the main work of the United States cloud is to enhance the stability of the cloud host, improve the cloud host template, backup, monitoring, security and other work. It is expected that in September 2014, the United States cloud will release its third version of the update, continue to burnish its product details. Technical framework The United States cloud initial selection of the time to OpenStack, cloudstack, Eucalyptus hav

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

With the emergence of network virtualization solutions, many companies are developing SDN policies to make the network more flexible and better managed, so as to apply to infrastructure as a service mode and virtual resource configuration. With SDN, engin

Sub-mode can be combined with some network routing tools to complete a small-scale cluster network pod interconnection. We mainly talk about the extension of the MLM. Kubernetes supports the MLM specification with the use of the MLM plug-in, and invokes various network plugins developed by other vendors and individuals to comply with the specifications of the company, such as Calico Flannel .

Bengocloud blog Http://bengo.blog.51cto.com/4504843/795619 This article is very cutting-edge. After reading this, I think Cisco technology is much more convenient. The VM solution is a little complicated. Reply from the blogger: 16:46:16 However, this is also the helplessness of software vendors. After all, there are tens of thousands of lines of code in physical box. First, it is difficult for outsiders to change the code, and second, hardware vendors do not give a chance to c

Author: Fan Jun Frank Fan) Sina Weibo: @ frankfan7 Network virtualization will be the last mile in the journey to realize the vision of a software-defined data center. IDC estimates that the network virtualization market will grow from 2013 million dollars in 360 to 2016 billion in 3.7. Many giants have made great strides, and many new startups have targeted this direction. Let's talk about what this means from the following aspects. IGame between giants As cloud computing gradually enters the m

The class dpif_class abstracts the communication interfaces between the ovs switch user space and the core layer datapath (via Netlink). The layer is based on performance and production efficiency. The interface dpif_class, user-layer ovs-vswitchd sends various ports, stream tables, queries, and other actions to the kernel layer for actual execution. For example, we add a port to ovs, then, the dpif_linux_vport request for adding the port is constructed from the user space to the datapath layer.

these projects may become part of docker in the future. Next let's take a look at these five projects. WeaveDeveloped by Zett. Io, it can create a virtual network to connect docker containers deployed on multiple hosts. All the containers via weave are like being connected to the same network switch. The applications using the network do not need to configure port ing and links. External devices can access the services provided by application containers on the weave network, and existing inter

C + + memory overflow is an obstacle to large-scale network emulation!Solution: It is not scary to encounter this problem, first look at the current simulation of the number of packets is not huge, is to find each packet in which module stay, change the corresponding code. If this is not the problem, then construct a simple network, Replace the module you wrote with the module in inet to find the problem module and change it.About the story:Today, we find that the switch has created a match stru

Google shares the specifications and standards of optical fiber networks A few days ago, Google is introducing some specification standards for fiber optic networks to help promote the adoption of Software Defined Network Technology (SDN.

White Box switch: three methods for network programmability (1) Even the most demanding IT professional, one word will attract his attention: cost saving. When there is a white box switch in the market-that is, a kind of consumer switch hardware that is pre-installed with a third-party network operating system, network engineers generally hear or understand that this new method may save costs. However, as the concept of network programmability becomes more and more important, cost saving is not

to the distributed vswitch of another server and transparently connect to its vswitch network. Figure 3. Distributed vswitch One of the most important projects in this period is Open vSwitch, which will be discussed in this article.One problem with isolating local traffic on the server is that the traffic is not externally visible (for example, for network analysts ). The implementation solves this problem through various plans, such as OpenFlow
