Title: Software Defined RAN (SDRAN) Evolution: Challenges and Opportunities
Speaker: Alex Jinsung Choi – CTO & EVP, SKT, Korea
Mobile Traffic has been increased rapidly and the amount of traffic varies according to time, place, and big event. It is difficult for operators to cope with the change of traffic using legacy RAN, because it has the H/W centric structure. This stiff structure leads to high cost when the operators try to reallocate radio resources dynamically. To increase radio resource utilization and reduce TCO, Rearchitecture of RAN(referred to SDRAN) is required. This new architecture is characterized by open H/W, open S/W, user plane-control plane separation, L1 split and business enabling platform(MEC: Mobile Edge Cloud).
SDRAN will have challenges such as mission critical requirement, real time processing, and capacity issues. To exceed those challenges, SK Telecom is trying to develop SDRAN trial system and leading the global ecosystem: OCP, TIP, and ON.Lab

Keynote #3-1 (Thursday, June 9, 2016)
Title: Network Function Virtualization and Flexible Service Chaining in Multi-Domain/Provider Environments: Recent Developments
Speaker: Robert Szabo – Ericsson, Hungary
Cloud networks provide various services on top of virtualized compute and storage resources. The ﬂexible operation and optimal usage of the underlying infrastructure are realized by resource orchestration methods and virtualization techniques developed during the recent years. In contrast, service deployment and service provisioning in carrier networks have several limitations in terms of ﬂexibility, scalability or optimal resource usage as the built-in mechanisms are strongly coupled to the physical topology and special purpose hardware elements. Network Functions Virtualization (NFV) opens the door between cloud and carrier networks by providing software-based telecommunication services which can run in virtualized environment on general purpose hardware. Our goals are to unify software (NFV) and network (service chaining) resource management into a common framework that could be used for end-to-end service creation.
In the framework of the EU-FP7 UNIFY project we created novel architecture supporting automated, dynamic service creation based on a ﬁne-granular service chaining model, SDN and cloud virtualization techniques. As a sequel, in the scope of the EU H2020 5G Private Public Partnership program’s 5G Exchange project, we work on multi-provider extensions to enable dynamic NFV and SFC services across multiple provider domains.
The talk will summarize recent developments and some learning based on corresponding proof of concept prototype implementations.

Title: NetroSphere and NetworkAnalytics – Innovation of network architecture and operation beyond SDN/NFV evolution
Speaker: Kohei Shiomoto – NTT Labs, Chair of IRTF NFV RG, Japan
As a number of diversified network equipments are deployed in the carrier networks, we need to overcome the limit of development, technology, and operation by transforming from vertically-integrated silo-style development to horizontal collaborative open innovation. Software-Defined Networking (SDN) and Network Function Virtualization (NFV) is expected to create horizontal collaborative open innovation by enabling softwarized functions running over commodity server and switch-router hardware. We are pursuing component-level disaggregation beyond SDN/NFV to create healthy sustainable ecosystem where new players can join without any barriers. NetroSphere is a paradigm where we deepen disaggregation into component-level and assemble components to provide agile and adaptive services to service provider and to reduce cost by commoditization. In order to reduce cost, support service creation, and improve resiliency and agility, NetroSphere introduces (1) Separation between optics and electronics, (2) Separation of functions from equipment, and (3) Separation of resources from equipment.
NetworkAnalytics is a key enabler of NetsroSphere concept, where we understand what’s going on network by analyzing diversified kinds of data (traffic measurement, QoE, configuration, error, SNS, etc.) collected from inside and outside of networks and to provide value to two-sided: end-users and service providers after we extract intelligence from analyzed data. However, today’s circumstances surrounding telecom carriers is getting complicated. Telecom carriers face two-sided situation where they have to provide value to both end-users and service providers. Service providers generate traffic source and have strong influence traffic demand matrix while end users enjoy fixed-mobile diversified services (web browsing, video streaming, etc.) making traffic prediction hard. Carrier network is growing and getting complicated with a number of diversified network equipments provided by multi-vendors. To cope with the complicated situation, we are pursuing inter-disciplinary research framework by combining research fields such as machine learning theory, control-theory, information theory in addition to optimization theory, graph theory, statistical analysis, queuing theory, etc. Traffic data, syslog data, and Twitter data is analyzed for various network operations: traffic-engineering, trouble-shooting, QoE-sentiment analysis. We call this inter-disciplinary as “NetworkScience”. where different field of technologies are employed in addition to existing network technologies. Machine-learning, information theory, control theory, etc. are introduced.
This keynote provided an overview of R&D activities on NetroSphere and NetworkAnalytics conducted in NTT R&D labs.
