Openstack meetup: NFV and Openstack
The document outlines the concept of Network Function Virtualization (NFV) and its relationship with OpenStack, detailing its architecture, benefits, and use cases in telecommunications. It highlights the role of ETSI in defining NFV standards, the management and orchestration framework, and the integration of various virtualized network functions. Additionally, it discusses challenges related to security and the collaborative efforts within the industry to advance NFV implementation.

- 20. NFV & OpenStack?? Ex Security Security-specific? Over 1.7M lines of code ~ 6 meters or 20 ~ 6 meters feet ? How can I ensure there is no security breach in 1.7M lines ? ? How does Openstack prevent back doors ? ? How does Openstack support secure boot, certified VM? ? How can I define security rules for an SDN application to change a flow table on an SDN switch that is provided by a IaaS Provider that may change along the life of the service ? ? How can I ensure that the memory I am sharing will not be accessed by somebody else ? ? Can I present the system admin to access my personal data etc © Copyright 2012 Hewlett-Packard Development Company, L.P. The information contained herein is subject to change 20 without notice. Many blocks interact with Keystone Keystone is not the only entity that deals with security Keystone deals with security & policies, but NFV will need end to end security & policies across end to end network, at ?NFVO level : how to synchronize? etc
