This document discusses network orchestration and Astara, an open source project for provisioning network functions in virtual environments. It provides background on software defined networking (SDN) and network function virtualization (NFV). It then describes Astara, including its architecture and goal of tying together OpenStack neutron. It follows the "FOUR O" principles of being open source, community, development and design.

- 10. SDN vs NFV Category SDN NFV Need ● Separation of Control and Data Planes ● Programmability of network Relocation of Network functions from dedicated appliances to generic servers Target Location ● Campus ● DC/Cloud Service provider network Target Devices Commodity servers and switches Commodity servers and switches Initial Applications Cloud orchestration and networking Routers, firewalls, gateways, CDN, WAN accelerators, SLAs Protocols OpenFlow None yet Formalization Open Networking Forum (ONF) ETSI NFV Working Group

- 13. Astara A network resource in software for provisioning the required network functions in virtual environments Thats what happens in an OpenStack deployment. It simplifies the daily operations of OpenStack operators by providing a Lifecycle management and Orchestration platform. Configures and Manages network services including routing, firewall, VPN and Load Balancing in multi-tenant OpenStack environments.
- 14. Astara ● A sanskrit word meaning carpet. ● Project started as Akanda and then renamed to Astara. ● Original name is "The RUG" A repeated line in the film "The Big Lebowski" That rug really tied the room together, did it not? ● "The Rug" is trying to tie OpenStack neutron in a single block.

- 19. Follows the FOUR O ● Open Source: – Uses Apache v2.0 license. – No library dependencies on how the projects are distributed or deployed. ● Open Community: – Leadership is chosen based on the contributions to the project. – Regular IRC meetings and everything is logged ● Open Development: – All code reviews are through the OpenStack infra CI – Liaison for cross-project teams in getting Astara collaborations. – Contributes to oslo as the opportunity arises. ● Open Design: – First design meeting at the Kilo summit and will be continued. – IRC and openstack-dev mailing list will be discussing the design.
