In the OpenStack grizzly version, the quantum component introduces a new network service: LoadBalancer (Lbaas), and the architecture of the service complies with the Services insertion framework. LoadBalancer provides the tenant with a load balancing of traffic to a set of virtual machines, the basic implementation of which is to generate Haproxy configuration files in Neutron-lbaas-agent and then start Hap

The Load Balance as a service (LBaaS) is an advanced network service provided by Neutron.LBaaS allows tenants to create and manage load balancer on their own networks.Load balancer can be said to be a relatively basic component in a distributed system.It receives the request from the front end and then forwards the request to a processing unit in the backend resource pool by a balanced policy to complete processing.The load balancer allows for high-av

In the previous section, we have configured and tested LBaaS, and today we focus on how Neutron uses Haproxy to achieve a balanced balance.Running IP netns on the control node, we found that Neutron created a new namespace qlbaas-xxx.The namespace corresponds to the pool "Web servers" we created. Its naming format is qlbaas-You can view its settings through IP a.The VIP 172.16.100.11 is already configured on the namespace interface. The corresponding

Neutron core plug-in is a core component of the development of the entire Neutron project, which is like an adhesive layer (glue) between the logical API layer and the actual implementation layer. As the neutron project evolves, the more loving plugins are introduced, they come from various open source projects and communities (such as Open VSwitch and Opendaylight), and the vast majority of vendors (vendor, such as Cisco, Nuage, Midokura And so on). At the beginning of the Kilo development cyc

Kubernetes network corresponds to the following table: POD----> virtual machines Service-------> LoadBalancer Endpoints-------> Pool Service back-end pod----> member However, because Kubernetes supports setting up multiple service ports on the same service, each load balancer for neutron supports only one external port.

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

From the network function and the implementation of the corresponding underlying network device, the Port corresponds to the VNIC's corresponding TAP/TUN device mounted by the VM, And the Subnet is only a data set of IP address pools, the Network must correspond to the assigned Network type and the corresponding isolation domain ID.

Currently, Neutron has implemented the L2 layer plug-in as shown in Figure 6. linuxbridge implements the Linux bridge, the openvswitch plug-in implements the openvswitch bridge, and the bigswitch plug-in implements an SDN controller, ml2 is a general plug-in. These L2 plug-ins are mainly divided into the plugin part of the database and the agent part running on the computing node. The fields written by plugin to the database are different but not many,
