to a neutron security group.Ingress is responsible for the external provision of services, through Nginx to provide a separate interface to achieve the external provision of all services in the cluster, thereby replacing the existing implementation of exposing each service with Nodeport. At present, Kubernetes's Ingress provides nginx and GCE two kinds of implementations, interested students can directly refer to the official documents, Https://github.com/kubernetes/ingress/tree/master/controll

visibility into networked storage, including Ethernet SAN technologies (e.g. FCoE or AoE), that Typica Lly dominates bandwidth usage in the data center. Looking forward, there is a number of tunneling protocols being developed to connect virtual switches, Including:gre, MP LS, VPLS, VXLAN and NVGRE. As new protocols is deployed on the network they is easily monitored without any change to exiting SFlow agents ensuring End-to-end visibility across the

Netperf can test TCP network performance, UDP network performance, and can simulate client/server long connection or short connection scene, so it can be more close to the actual network environment for testing and evaluation.

applications Access databases, API interface calls, and so on, so the network must be interoperable and multi-tenant isolated, with the current Docker network having two major camps, CNM, and MLM. Which Calico can be considered both camps, it can be integrated with the kubernetes, compared to the overlay network in the network transmission process still has a clear advantage, as shown, reduced packet encapsulation improves network transmission and packet processing efficiency.

tools: SDN and NFV. SDN is an innovation oriented towards network architecture, and NFV is an innovation oriented towards device architecture, using these two tools makes it extremely simple to configure and deploy network devices, or directly distribute the forwarding table through the Controller, or directly issue the VXLAN configuration through the controller without manual intervention. People only need to click on the Controller to complete busi

The IP wrapper protocols used by each virtualization platform are different, such as: Virtual extensible Local Area Network (VXLAN), stateless Transport tunneling Protocol for Network Virtualization (STT) and generic Routing encapsulation (GRE).

course, the choice of specific options depends on the respective company's own infrastructure and design objectives.

Welcome PR Ah, at present we have serious shortage of groups, no energy to do too much, only in their own scope of work, by the way the code open source.

the cloud platform (for example, code logic directly implemented in OpenStack Neutron Server ). Controllers in this scenario cannot be used as general SDN controllers. On the contrary, General SDN controllers cannot be directly used in cloud computing network scenarios. As for the second question, it is easy to understand why it is a misunderstanding. Even controllers must be customized for cloud computing scenarios, not to mention SDN switches. Therefore, instead of using an SDN switch to supp
