Intro to OpenStack Astara (Spring '16)
- 2. NEUTRON IN 2 MINUTES
- 3. OSI Model Physical Layer Data Link Layer Network Layer Transport Layer Session Layer Presentation Layer Application Layer 1 2 3 4 5 6 7 TCP, UDP IPv4,IPv6, ICMP HTTP, DNS, etc ARP, Ethernet, VLAN
- 4. OpenStack
- 5. What does the user see? Compute API Network API Storage APIGUI, CLI, API Libs KVM ML2 Plugin Ceph
- 6. Abstractions Net1 10.0.0.0/24 Nova Neutron L2 virtual network virtual port virtual server virtual interface (VIF) virtual subnet VM1 10.0.0.2 VM2 10.0.0.2
- 7. Using the API… VM1 10.0.0.2 VM2 10.0.0.2/172.16. VM3 172.16.77.1 Tenant A Net1 192.168.0.0/24 Tenant A Net2 172.16.77.0/24 Public Net 10.0.0.0/8 VM1 10.0.0.2 VM2 10.0.0.2/172.16. VM3 172.16.77.1 Tenant B Net1 192.168.0.0/24 Tenant B Net2 172.16.77.0/24 Router Router
- 9. Building Networks… L2 vs L3 Tenant Isolation GRE/VXLAN/GENEVE VLAN © Malcolm Leman | Dreamstime.com
- 10. Traditional L2 802.1Q Aggregation tier must be HA MLAG is vendor proprietary Aggregate/Core Scalability limited number available MAC/ARP table limits East/West Bottleneck
- 12. Isolation via VXLAN VXLAN L2 encapsulated L3 IP Fabrics Scale Reduces L2 size ECMP (Equal Cost Multi-Path) Each link active Predictable latency Better failure handling
- 13. What is BUM Traffic? BROADCAST UNKNOWN UNICAST MULTICAST
- 15. Tunneling BUM with L2 Population A D CB
- 16. Neutron Operational Challenges Managing multiple services is challenging Each SDN/L2 backend is different Difficult to change Multi vendor deployments can be difficult Day Two Operations
- 19. ASTARA UNDER THE HOOD
- 20. “THE RUG” — ASTARA ORCHESTRATOR “REALLY TIED THE ROOM TOGETHER”
- 21. The Rug Control Plane Orchestration Logically Centralized Pluggable Drivers Multi-Process/Multi-Threaded Utilizes standard APIs/interfaces for Neutron, Nova, Glance and Ceilometer
- 22. The Rug Apache v2 Developed for OpenStack Production deployment since 2013
- 23. Reference Neutron neutron-server L2 AgentL2 AgentL2 AgentL2 AgentL2 AgentL2 Agent L3 AgentL3 Agent L3 AgentL3 Agent Database L3 Agent DHCP Agent L2 Agent Message Queue Adv Services neutron-server

- 27. Astara Benefits Dynamic Routing OSPF BGP Designed for IPv6 L2 Agnostic OVS, LinuxBridge or other solution
- 28. Astara Architecture Astara Management/ Orchestration Physical Network (L2) Nova Neutron Open:OVS/LinuxBridge Proprietary Astara OTT Support (L2 Agnostic) Astara Adv Services: Routing/LB/FW OpenStack APIs
- 29. Pluggable OTT Architecture Add new services easily Can enabled for tenants upload images Driver Based LBaaS (HAProxy, nginx) VPNaaS Routing (Linux, BSD, Cisco CSR). Support Services without OpenStack APIs Utilizes standard APIs/interfaces for Neutron, Nova, Glance and Ceilometer
