It is the individuals who invest the time and careful focus that is required to bridge both communities who will make this effort successful.” “Sometimes a standards effort will also create a reference implementation or snippets of code demonstrating an implementation. ….the standards licensing model might be incompatible with inclusion in an open source project” Ways of Working for Collaboration • Harmonization will benefit both ONAP and SDOs, but main objective to look for ONAP benefits • Use ideas from SDOs. • Be standards-compliant • Influence standards.

    ONAP VoLTE Blueprint Overview ONAP Voice over LTE Improves Agility and Slashes Costs for Communication Service Providers ONAP VoLTE Use Case Solution Brief 1 “By using ONAP to support the VoLTE Blueprint, we expect core network services to be delivered in a more agile fashion, as VNFs can be onboarded on demand and combined in distinct ways to create customized services for users in different verticals.” –China Mobile OVERVIEW: CURRENT CHALLENGES: SOLUTION: • VoLTE is being adopted by operators • Lack of agility • ONAP along with in order to improve voice quality and • High capital expenditures • Commercial vEPC, vIMS VNFs network efficiency • High operating expenditures • Commercial SDN controllers • Traditionally uses physical appliances • Reduced infrastructure utilization • Commercial cloud software • Current operations and management use manual processes Overview As Communication Service Providers (CSPs) move to data-only networks with LTE and 5G, a mobile core network technology called VoLTE allows voice to be unified onto IP networks. For a consumer, VoLTE provides better voice quality and faster call setup. For example, going from a traditional 8 kbps codec to a 13 kbps codec with improved compression can result in a high-definition sound experience with higher clarity. VoLTE can also be twice as fast as voice technologies in terms of initial call setup. VoLTE enables a CSP to offer value-added services such as video chat associated with the same phone number. The CSP can cut cost by unifying all services onto IP and increasing the efficiency of the network. VoLTE also promises additional benefits such as lower power consumption as compared to over-the-top VoIP applications, seamless handoff between VoLTE and voice-over-WiFi and improved device interoperability across networks.

  • Orchestration White Paper
    ORCHESTRATION WHITE PAPER Lumina Networks, Inc. + 1 (669) 231-3838 [email protected] 2077 Gateway Place, Suite# 500 + 1 (800) 930-5144 www.luminanetworks.com San Jose CA 95110 Orchestration White Paper The Open Network Automation Platform - How Lumina Networks’ SDN Controller Helps Deliver Network Intent The Linux Foundation’s Open Network Automation Platform (ONAP) is the networking industry’s most broadly supported service orchestration initiative. With deep expertise in OpenDaylight, upon which ONAP is being built, Lumina Networks is ideally suited to provide an open source network control tool- set in a way that supports the capabilities and flexibility that service providers want and need. Introduction The trend in carrier-grade networking is toward virtualization and software-defined networking (SDN). Every service provider (SP) is moving to separate the software layer of networking from the underlying hardware to reduce their de- pendence on expensive, purpose-built equipment and to gain agility in their operations. This abstraction process allows them to move their now-virtualized networking software to general purpose compute platforms—the same kinds of inexpensive white box hardware and bare metal platforms that applications and other services run on today. When the network itself is virtualized, it runs in software as if it is just another application. This creates a challenge in that the operation of the network must be coordinated closely with the operation of the applications and services that -nor mally run on the network, as well as with the underlying infrastructure. “Orchestration” is the industry term for the co- ordinated management of all the network and compute elements needed to deliver a virtualized network service.
