OF-config is an openflow protocol released by ONF and a southbound interface protocol for connecting network devices. It provides open interfaces for remote management OF openflow switches, you can use the OF-config protocol to configure and adjust the openflow switch attributes in the network, including configuring the connection parameters between the switch and the Controller, configuring the

Network virtualization is now a hot topic, and major manufacturers are scrambling to grab this cake. Technologies involved include virtual Emulation for NICs, I/O pass-through, SR-IOV), virtual access technology for networks VN-Tag/VEPA), covering network switching VXLAN/NVGRE ), and Software Defined network SDN/OpenFlow. For details, refer to the blog "Network virtualization-ongoing network revolution" published by EMC China Research Institute, which

Take control of your hybrid workloads, including running them in containers, and move them across servers, racks, and Clou DS utilizing the power of VXLAN and NVGRE based virtual networking and multitenanted hybrid gateways. Optimize your cost/performance when you converge Remote Direct Memory Access (RDMA) and tenant traffic on the same teamed Network Interface Cards (NICs), thereby

Floating IP allows the extranet to directly access the instance in the tenant network. This is achieved by applying the iptalbes NAT rule on the router.2. Floating IP is configured on the router extranet interface rather than instance, which requires special attention.At

. Network virtualization is a solution, and software-defined networks are only one of the many implementation methods of this solution. After extracting some network information and functions, we always have a way to store the information and keep abreast of their status. At this time, the software-defined network will be useful. There is usually a module that can be centrally controlled to implement these functions. Please pay attention to the following: implementation of graphic network Virt

communication and workload flow between multiple clouds are maintained, is extremely important. Only in this way can disaster recovery and high availability be ensured. If you want to create a hybrid cloud environment to deploy your workloads and transfer the workload securely between public and private clouds, you need to learn from Google, A way to convert virtual identifiers within a single data center is designed. There are many such examples. For example, because VPN (Virtual Private Netwo
