Benefits & Challenges: End Users

Benefit: Open Source – Freedom of choice with no vendor lock-in

Ability to build your own services and extensions Power to influence direction Typically less buggy and more secure (no backdoors!)

Benefit: Community-backed Project – Large vendor community – enough said

Large user base – fluid experience sharing Large developer base – easier to find skills

Build your own : Free (?) Commercial: Powered by ODP

Gateways Security & LB Appliances Overlay Control Servers Connec&vity ¡Service ¡Chaining ¡& ¡UX ¡

  • 1. IBM SDN-VE Platform: Unified SDN controller

based on OpenDaylight

  • 2. Connectivity Service Chaining & UX: A service

chaining framework that eases deployment of application patterns over the networking tier in data centers.

  • 3. Network Services: Routing, OpenFlow, Security

and LB services running on the controller

  • 4. Network Drivers: Plug-ins or drivers specific to

network technologies

  • 5. Virtual Appliances: Virtual-Physical Gateways;

Overlay control servers for end-point mgmt; Security & LB Virtual Appliances that are distributed for scalability.

  • 6. Data Plane: Virtual switches for data forwarding/

routing, as well as agents for HW elements to enable forwarding control via the SDN controller.

Network Virtualization with Open DOVE

  • DMC: The DOVE Management Console enable

configuration and management of tenants and logical networks and is service running on the controller.

  • DCS: The DOVE Connectivity Server is a scale out

cluster of virtual appliances that provide address dissemination and management of tunnel end points

  • DOVE Gateways: Gateways are either physical HW

switches or virtual appliances that enable physical networks/end points to participate in logical networks,

  • r allow for access to the internet.

There is ecosystem support for 3rd party security and LB virtual or physical appliances.

  • Virtual Switches: These are the data plane

forwarding elements that create and terminate tunnel end points and provide the overlay data functionality. They are implemented as part of a hypervisor vSwitch.

DOVE (Distributed Overlay Virtual Ethernet) is an overlay based network virtualization service that uses VXLAN for the data plane, and OVSDB for interfaces to the physical

Suite of OpenFlow Services

  • Flow Rep. | Span and Tap: To efficiently tap and mirror

traffic from points within the network for debugging and troubleshooting large scale networks.

  • SPARTA: A scalable per destination multi path service for

deployment in L2 Clos topologies that doesn't require new tunnel support in HW.

  • Load Balancer: A datacenter wide layer 4 stateless load

balancer which works at line rate along with traffic steering capabilities for scaling software appliances such as security, compliance etc. [not in product yet, contributed to ODP]

  • Logical Networks: Visually define and deploy multi-tenant

virtual networks on an OpenFlow fabric

  • Static Flow Pusher: Programming APIs for deploying user-

defined OpenFlow rules

  • Policy Manager: unified policy framework for managing

security rules, ACL, QoS, and service chain policies

  • OpenStack Neutron: Plug-in for integration with

OpenStack Networking using standard Neutron APIs including extensions for L3 and security groups.

  • Service Chaining: basic service chaining to support

application patterns on OpenFlow networks

Benefits & Challenges: Vendor

Challenge: Productization – User Experience (UX): Deployment | Usage | Verticals

Test: Interoperability, Scale, Availability Sync: synchronization issues with upstream code

Benefit: Community-backed Project –

Large user base – fluid experience sharing Large developer base – easier to find skills, solutions

Benefit: Raises the bar – Large vendor community – competitiveness

Agile developer community – internal process agility Pushes innovation via community Improves organizational culture

Benefit: Better Focus – Focus on customer-driven value

Flexible architecture retains corporate value
