OrchestraBon Brings It All Together

•  Cloud – flexibility and scale –  Infrastructure and compute for applica>ons and VNFs

•  SDN – end-‐to-‐end network control –  Automa>on and streamlined opera>ons

•  NFV – network funcBonality –  Cost-‐effec>ve, flexible network func>onality

•  Carrier Ethernet – connecBvity –  Connec>vity between end-‐points across a WAN and chaining

between VNFs to form a service

Where is LSO going?

If you are invesBng in LSO, what best describes your goals for this investment?

Other (please list) 10.9%

To build a new open, standards-‐based LSO system (replace exis>ng systems) 32.7%

To improve on/supplement the exis>ng set of opera>onal

support system tools(evolve away from current OSS when

possible) 56.4%

LSO Enriches Legacy OSS/BSS

•  Allowing service agility and facilitaBng automaBon

•  Streamlining operaBons

•  Enabling end-‐to-‐end mulB-‐domain control

•  Providing an open environment for service orchestraBon

MEF LSO Management

•  The MEF LSO Vision: Assured, Agile connec>vity services and business opera>ons, Orchestrated over mul>ple internal/external operator networks

•  Assure E2E service performance, SLA and security •  Orchestrate among all the service providers supplying components of the E2E service –  Leverages standardized service orchestra>on APIs

•  Business, network and service Agility all contribute to Service Providers’ opera>ons moderniza>on –  Enabler to Cloud IT-‐like customer experience

– Managed connec>ons as well as managed interfaces may be turned on and off.

– Throile up or back the bandwidth – Add or remove endpoints – Discovery of service capabili>es – Migra>on of services to different resources

Summary •  The MEF’s LSO Vision is for each func>on of the service lifecycle to

be automated. •  This is required to achieve agile, assured, and orchestrated

connec>vity services delivered by the Third Network. •  LSO orchestrates connec>vity services in the Third Network across

all internal and external network domains from one or more network operators.

•  LSO capabili>es will allow the Third Network not only to drama>cally decrease the >me to establish and modify the characteris>cs of connec>vity CE 2.0 services, but will also assure the overall service quality and security guarantees for these services.
