Offering SDN services with Evolved IP/MPLS Network (slides)

Mr. Lim Wong
(Cisco Systems, Inc. Hong Kong)

SDN introduces a shift in how networks are designed, operationalized and monetized, and will make them far more agile and responsive to service requirements.  NFV services provide the real-time network resource management needed to support on-demand services. With SDN and NFV working in concert, revenue generating services can be placed anywhere within the network, and invoked as needed according the needs of specific applications. This represents a clear opportunity for service providers to better monetize their networks, as service providers can exploit their abilities to guarantee SLAs for premium services, and continue providing volume-based services as well. This session will present the fundamental building blocks of SDN/NFV that one should consider for the implementations. We will explore how some of these concepts can be applied to traditional IP/MPLS network for revenue generating services.

Proactive Network Operation through Network Data Analytics

Dr. Keisuke Ishibashi
(NTT Network Technology Laboratories, Japan)

Recently, network anomalies such as cyber-attacks, network failures, and traffic spikes have become common occurrences and have impacted service performance. To minimize such impact, proactive approach in network operation is required. In this regard, bigdata generated from networks, such as syslog, access log, traffic data, performance metrics are expected to be sources of intelligence to enable the proactive network operations. In this talk, we show some use case of network data analysis for proactive network operations.

Software Defined Networking:
Why, When, Where, and How

Dr. Rung-Hung Gau,
(National Chiao Tung University, Taiwan)

The first wave of cloud computing was to centralize and virtualize servers into the clouds, with a phenomenal result. The emerging second wave, named Software Defined Networking (SDN), is to centralize and virtualize networking, especially its control, into the clouds. SDN deployment started from data centers and now expands to the model of “networking as a service” (NaaS) offered by the operators to enterprise and residential subscribers. By centralizing the control-plane software of routers and switches to the controller, and its applications, and controlling the data-plane of these devices remotely, SDN reduces the capital expenditure (CAPEX) and operational expenditure (OPEX) because the devices become simpler and hence cheaper and number of administrators could be reduced. SDN also enables fast service orchestration because the data plane is highly programmable from the remote control plane at controllers and applications. However, as we detach control plane from where data plane resides, new protocols shall be introduced between control plane and data plane, as the southbound API between controllers and devices and the northbound API between controllers and applications. As we further extend the control plane from controllers to applications such as Service Chaining (SC) and data plane from devices to Network Function Virtualization (NFV), newer mechanisms and APIs need to be added to these APIs. We argue why, when, and where SDN would prevail, and then illustrate how to make it happen. We shall introduce the key technology components, including OpenFlow, SC, NFV, and Network Service Header (NSH) and then review the issues on standardization, development, deployment, and research.

Software-Defined Networking from Concept to Reality

Dr. Eun Kyoung PAIK
(KT, Korea)

Emerging Internet applications and services demand for dynamic networking environment. Software-Defined Networking (SDN) provides flexible and agile networking infrastructure to meet those novel requirements. This talk illustrates the concept and realization of SDN from the perspective of open networking/software/ hardware. Firstly, this talk introduces the motivation, basic concept, and core technologies of SDN. Secondly, it addresses the latest state of standardization with commercialization issues. Finally, it illustrates use cases over classified fields, then concludes with the vision of SDN.
