RedHat: RHSA-2021-3488:01 Important: Red Hat OpenStack Platform 16.2
Summary
Neutron is a virtual network service for OpenStack. Just like OpenStack
Nova provides an API to dynamically request and configure virtual
servers, Neutron provides an API to dynamically request and configure
virtual networks. These networks connect "interfaces" from other
OpenStack services (e.g., virtual NICs from Nova VMs). The Neutron
API supports extensions to provide advanced network capabilities
(e.g., QoS, ACLs, network, monitoring, etc.).
