ALCATEL-LUCENT “END-TO-END” SDN ARCHITETCURE

PROGRAMMABILITY

Policy-based network abstraction and open APIs

• Simplified representation of network to applications by service-layer abstraction of network constructs to hide underlying complexity

WEB VELOCITY & SCALE

Demand-driven service activation and provisioning

• Customer trigger (packet, flow, VM creation) initiates dynamic network provisioning and service activation as directed by pre-defined policies

NETWORK RESOURCE EFFICIENCY

Dynamic resource control with global network view

• Extend cloud efficiency model to WAN • Leverage network statistics, multi-layer topology, dynamic virtual

network state + control (slicing) to optimize end-to-end service delivery

Value Proposition• Reduces up to 40% of datacenter traffic

• Increases server utilization by 30%

• Plug and play Networking with full network abstraction

• Seamless connectivity to enterprise VPNs, across datacenters

• Federation of Cloud Orchestration (Openstack, Cloudstack, Vcloud, etc)

• Hypervisor independence

• Scales by leveraging 10y field proven control-plane function in SROS
