1. Neutron What’s new in Havana? Arvind Somya Software Engineer Cisco Systems Inc.

2. Modular Layer 2 (ML2) Driver Based Combines OVS and Linuxbridge VXLAN Support L3 Separation L2 Population Vendor Drivers Available

3. Original Goal: The Modular Layer 2 (ML2) Plugin is a framework allowing OpenStack Networking to simultaneously utilize the variety of layer 2 networking technologies found in complex real-world datacenters. ML2 was designed to ease the burden of adding new L2 networking technologies into OpenStack Networking. ML2 will deprecate the Open vSwitch, LinuxBridge, and Hyper-V monolithic Neutron Plugins It works with each of their existing L2 agents simultaneously

4. ML2 exposes two different types of drivers: “Type” and “Mechanism” ML2 TypeDrivers: Maintain type-specific state Provide tenant network allocation Validate provider networks Current TypeDrivers: local, flat, VLAN, GRE, and VXLAN ML2 MechanismDrivers: Responsible for taking information supplied by TypeDrivers and ensuring it is properly applied given the specific networking mechanisms which have been enabled Current MechanismDrivers: Arista, Cisco Nexus, Hyper-V, L2 Population, LinuxBridge, Open vSwitch, Tail-F NCS

5. Maintain type-specific state Provide tenant network allocation Validate provider networks Current TypeDrivers: local, flat, VLAN, GRE, and VXLAN

6. Responsible for taking information supplied by TypeDrivers and ensuring it is properly applied given the specific networking mechanisms which have been enabled Current MechanismDrivers: Arista, Cisco Nexus, Hyper-V, L2 Population, LinuxBridge, Open vSwitch, Tail-F NCS MechanismDrivers can work with many different technologies: Agent based MechanismDrivers (Hyper-V, LinuxBridge, and OVS) Controller based MechanismDrivers (Tail-F NCS and OpenDaylight) ToR switch MechanismDrivers (Arista and Cisco Nexus)

8. Load Balancing as a Service Multiple Network Node Driver Based OpenSource - HAProxy Vendor Drivers Available (Nicira Service Plugin) Agent based solution Horizon Integrated

9. Lbaas Simple Workflow Create a Pool of VIP’s from a Neutron Subnet Add Member instances to the Pool Optionally associate monitors with Pools Monitors check the backend members of a VIP Can use Ping, TCP, HTTP, HTTPS for health checks Can specify the delay, timeout, retries, url and expected codesfor each monitor Specify a weight for added members and a port number. Can load balance using: Round Robin Least Connections Source IP Add VIP to the Pool (One per pool)

10. VPN as a Service Site-to-Site IPSec Pre-Shared Key Multiple Node Support OpenSource based on OpenSwan Under development: MPLS VPN, BGP MPLS VPN Horizon Integrated

11. VPN as a Service Simple Workflow Create IKE Policy Tenant Name Create IPSec Policy Tenant Name Create a VPN Service Tenant Subnet Router Auth algorithm: Sha1 Encryption Algorithm: aes-128 (aes 3des, aes- 256, aes-192) Phase 1 negotiation mode: Main Mode (Aggressive mode) PFS: Group5 (group2, group5, or group14) IKE Version: v1 (v2 ) Transform protocol: ESP (AH, AH-ESP) Encapsulation mode: tunnel (transport) Auth algorithm: sha1 Encryption Algorithm: aes-128 (aes 3des, aes-256, aes-192) PFS: Group5 (group2, group5, or group14) Create IPSec site connection Tenant Peer Id Peer CIDR(s) Peer Address Psk IKE Policy IPSec Policy VPN Service Id

12. Firewall as a Service Stateless Filtering at the Edge Vendor Drivers Preview Available in Havana Agent Based Horizon Integrated

13. Firewall as a Service Simple Workflow Create a Firewall Policy Add Firewall Rules Can specify Audited attribute Source, dest IP, port etc. Strict Ordering Create a Tenant Firewall

14. Additional New Features Improved Horizon Integration Panels for Load Balancer, Firewall and VPN as a service. DHCP Per Port Options Plugin Improvements

15. Looking ahead to Icehouse... Parity with nova-network Improved IPv6 Support L3 High Availability Plugins and Drivers External Testing New Plugins and Drivers

16. Icehouse Advanced Services Load Balancing as a Service Multiple pools per VIP VPN as a Service SSL VPN API Firewall as a Service Revised API
