As we move away from legacy models for providing network services, namely dedicated physical appliances, to virtualized network functions servicing single or multiple data centers, the industry is experiencing the heavy lifting of bringing up new technologies for orchestration, SDN, and integrating the dynamic NFV model with the OSS/BSS Telco providers are using to control their ever-growing networks.
The community of vendors, enterprises, and service providers is using Open Source to share and expedite this technology shift with a focus on quickly modernizing the infrastructure.
The lower three layers of the stack enjoy broad community support as the Reference Architecture for NFV and SDN:
•OpenStack – Used to orchestrate the infrastructure
•OpenDaylight (ODL) – The SDN controller, enabling feature-rich, scalable solutions for network virtualization, service chaining, and other functions
•Open vSwitch (OVS) – An entity controlled remotely by the SDN controller, providing inter-VM connectivity and emerging SLA, QoS, and security functionality at customizable granularity down to per-flow levels
In this webcast, ConteXtream and Intel will describe the roles of each layer and the status of the basic functionality available today. A special focus will be given to ODL’s scalability and functionality challenges and solutions for intra- and inter-data-center networks (e.g. Telco networks). We will further discuss how overlay network standards are used to achieve these goals and how ODL federation is performed along IETF-RFC lines to achieve robust fan-out of control capacity. We will also demonstrate new capabilities and levels of flexibility powered by a combination of inter-data-center ODL, service chaining, and NFV technologies.
