nicira

This month, Nicira Networks suddenly released a new network virtualization architecture and software, announcing the success of copying VMware in the server field. The company has been carefully planning its own development. After four years of operation, it not only released a network virtualization platform, but also published the names of several mainstream companies that have deployed their network virtualization architecture in the production env

an OpenStack environment. In the mainstream virtualization platform, only Microsoft Hyper-V currently does not support NSX.NSX Network Virtualization sub-vsphare environments NSX (NSX-V) and NSX (NSX-MH) in a multi-virtualized environment are different software, the latest versions are 6.2.0 and 4.2.4, which need to be understood before deployment. Among them, NSX-MH is more like the original Nicira NVP platform, mainly on the KVM and Xen, based on t

, need to be virtualized. However, once these components are virtualized, engineers need to be able to programmatically control the configuration of these resources. To achieve this goal, you must eliminate physical network limitations such as VLAN scalability, MAC scalability, virtual machine mobility, and IP address conflict ). In addition, the network administrator needs the same virtual network visibility and functions as the physical network. Some server hypervisor can enable VMware to have

(ONF. Traditional network providers have to keep pace with the times, or they may be bypassed by major customers for independent development. Nicira, A emerging network virtualization company, has seized the opportunity of the times and integrated it with Openstack to provide solutions for many giants including eBay. VMware, which is already in the leading position in the server virtualization market, has also made frequent attacks. In June 2012,

also have to keep up with the times, otherwise it is likely to be the big customers around the development of their own. Nicira, a new network of virtualization start-ups, has taken advantage of the times and OpenStack deep integration to provide solutions for many giants, including ebay. VMware, already a leader in the server virtualization market, has also been hit by the punches. In June 2012, VMware12.6 billion dollars in mergers and acquisition

software sector, Software Defined Network (SDN) program code is also being developed. New startups include Big Switch Networks and Nicira, which have been acquired by VMWare, they already have their OpenFlow controller software. Earlier this month, 18 large communication equipment vendors and software vendors announced cooperation to promote an Open Daylight program designed to provide SDN controllers and related application interfaces (APIS).

In the opinion of Microsoft, the major support vendor, some network performance problems can be solved through the intelligent network card, that is, the NVGRE endpoint processing on the Smart Nic to uninstall the hypervisor vSwitch. The smart NIC also has APIs integrated with the overwrite controller and hypervisor management system. There is a controller

network technology. Previously, openstack has provided support for open vswitch, Cisco UCS/nexus, Linux bridge, nicira, Ryu openflow, NEC openflow, and other technologies. By cross-server allocation of L3/L4 and Dynamic Host Configuration Protocol (DHCP) services, the openstack network achieves larger scale and higher availability. In addition, the new version provides a new load balancing as a service (lbaas) framework and API to facilitate the inte

cheaper hardware products. This will make the network more flexible and cost-effective. In July this year, VMWare acquired nicira, a leading enterprise in SDN, at a price of 1.26 billion. Since then, enterprises developing SDN products have become the darling of the technology world. In October this year, micira's biggest competitor, big switch, received $25 million in funding, and hosla also participated in the investment. Five days ago, plexx

The rise of SDN Traditional network management mode is slow, often through the command line interface, manual configuration, high operating costs, network upgrade time is long, lack of flexibility, response to demand changes slow, and prone to errors. In July 2012, SDN represented the maker Nicira was acquired by VMware for $1.26 billion, and Google announced its success in deploying SDN in its global network of 10 IDC networks, prompting SDN to attr

The document specifically mentions Nicira, which is because its flagship product contains some of the Open software, which in turn leads to long-term discussions about the risks involved.The document describes the relationship between VMware and EMC in a wo

If the external disk array supports virtual Volumes, it can also be driven by VMware SPBM, while the cloud Object storage can be seen as VMware's ambition in the future, perhaps, In the future, VMware will even incorporate object storage from the cloud platform into the SPBM landscape. In fact, the development of Vsan has been at

Networking Vendors Cisco and Arista is actively promoting VXLAN and has collaborated with VMware to develop and test the Technology on their products. Cisco highlighted VXLAN at their Cisco Live User conference again in June and Arista are demoing it at VMWorld, Howeve R with the

degree of integration between the controller and the network device. In a OpenFlow environment, the controller uses the OpenFlow protocol and the NETCONF protocol to talk to the switch. (OpenFlow is the API that sends streaming data to the switch, and netconf is the network Settings API.) ) SDN: Basic Architecture In the current SDN approach, the vendor provides applications and a single controller in one product. For example, Nicira/vmware encapsu

OpenvSwitch enables interconnection between Docker containers and hosts 1. Introduction to OpenvSwitch Open vSwitch (OVS) is a virtual switch dominated by Nicira Networks that runs on a virtualization platform (such as KVM and Xen. On the virtualization platform, OVS can provide a layer-2 switching function for dynamically changing endpoints to control access policies, network isolation, and traffic monitoring in virtual networks.
