openstack neutron architecture

We discussed the basic concepts of Neutron, and today we begin to analyze the architecture of Neutron.Neutron ArchitectureLike other OpenStack services, Neutron also employs a distributed architecture that provides network services from multiple components (sub-services).The

the above rules is allowed-A nova-filter-top-j nova-compute-local2. FWaas2.1 ConceptStarting with the Havana version, Neutron provides a network four-layer firewall virtualization reference implementation Firewall-as-a-service, referred to as FWaas, based on the Neutron L3 Agent. The analysis in this paper is based on the OpenStack Juno version. In the Juno vers

The OpenStack Kilo version, the 11th version of OpenStack, an open source project, was officially released in April 2015. Now is the time to look at what has changed in this version of neutron and what new key features have been introduced.1. Expand the Neutron development community (scaling the

From the name of the folder also basically can draw the role of the directory code, a few important folders are as follows:Agent: mainly L3 agent and L3 agent ha related code;Common: It is mainly the interaction layer between the bottom drive and the Linux system command;DB: is neutron each function and the database interaction data code;Extensions: mainly includes some extended functions, including DVR code, etc.;Plugins: is the core plugin code, inc

The first two posts examine the network architecture of the compute node and the neutron node respectively. This paper analyzes the process of specific network process through some typical process cases.0. EnvironmentWith learning OpenStack (7): Neutron in-depth learning OVS + the environment used in the

Disclaimer: The recent installation of the kilo version of OpenStack found that there were very few existing web tutorials and that most of the tutorials did not install successfully, So write this tutorial. The installation of OpenStack is complex, and this tutorial does not guarantee that it will be installed successfully in different environments. Personal installation tutorials are also prone to erro

I. Overview of neutronAs we all know, the entire open stack network is implemented through the neutron component, it has become the most complex part of the entire open stack, this article focuses on neutron implementation model and application scenario, gossip less, into the topic.1.
