#openstack neutron deep dive | openstack wallby, openstack tutorial What is Openstack Neutron? Neutron is an OpenStack project to provide "networking as a service" between interface devices (e.g., vNICs) managed by other Openstack services (e.g., nova). Starting in the Folsom release, Neutron is a core and supported part of the OpenStack platform (for Essex, we were an "incubated" project, which means use is suggested only for those who really know what they're doing with Neutron). If you're a networking geek and like to hack on OpenStack, pl join www.theskillpedia.com Why Neutron? Give cloud tenants an API to build rich networking topologies, and configure advanced network policies in the cloud. Example: create multi-tier web application topology Enable innovation plugins (open and closed source) that introduce advanced network capabilities Example: use L2-in-L3 tunneling to avoid VLAN limits, provide end-to-end QoS guarantees, use monitoring protocols like NetFlow. Let anyone build advanced network services (open and closed source) that plug into Openstack tenant networks. Examples: LB-aaS, VPN-aaS, firewall-aaS, IDS-aaS (not implemented), data-center-interconnect-aaS. Horizon GUI support for: Neutron L2 and L3 network and subnet creation/deletion Booting VMs on specific Neutron networks. API Extensibility Framework, including extensions for: "provider network", which maps Neutron L2 networks to a specific VLAN in the physical data center Using Neutron Forget documentation, I just want to get the code!: Neutron Downloads Detailed information for programming against v2.0 of the Neutron web services API is available in the Neutron API Guide If you are looking for information on using Neutron with devstack, please see: NeutronDevstack . Neutron lets you use a set of different backends called "plugins" that work with a growing variety of networking technologies. These plugins may be distributed as part of the main Neutron release, or separately.
