  1. Neutron What’s new in Havana? ArvindSomya 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. What is Ml2? • 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 “Drivers” • 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. ML2 TypeDrivers • Maintain type-specific state • Provide tenant network allocation • Validate provider networks • Current TypeDrivers: • local, flat, VLAN, GRE, and VXLAN

  6. 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 • 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 (NiciraService Plugin) Agent based solution Horizon Integrated

  9. Lbaas Simple Workflow Create a Pool of VIP’s from a Neutron Subnet Add VIP to the Pool (One per pool) • Can load balance using: • Round Robin • Least Connections • Source IP Optionally associate monitors with Pools Add Member instances to the Pool Specify a weight for added members and a port number. 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

  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 a VPN Service • Tenant • Subnet • Router • Authalgorithm: 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) • Create IKE Policy • Tenant • Name Create IPSec Policy Tenant Name • Create IPSec site connection • Tenant • Peer Id • Peer CIDR(s) • Peer Address • Psk • IKE Policy • IPSec Policy • VPN Service Id • Transform protocol: ESP (AH, AH-ESP) • Encapsulation mode: tunnel (transport) • Authalgorithm: sha1 • Encryption Algorithm: aes-128 (aes 3des, aes-256, aes-192) • PFS: Group5 (group2, group5, or group14)

  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 Can specify Audited attribute Create a Firewall Policy Add Firewall Rules 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
