Tutorial 1, Symposium Space, Raiosha
- Scaling Dense-Traffic Cellular Networks Through Software Defined Networking
- The exponential growth of cellular network traffic and flattening spectral efficiency are two of the biggest challenges facing 4G and future 5G wireless cellular networks. On the demand side, network traffic is exponentially growing and becoming much more diverse, while on the supply side the available spectrum and spectral efficiency are flattening out. The common approach to overcome the problem of increasing per-user capacity and spectral efficiency is to make cells smaller and bring base stations closer to mobile hosts, resulting in extremely dense network deployments. The current architectures are however unable to support such extremely dense cellular deployments. Adopting fundamentals of software defined networking (SDN) in designing layers of system and abstractions can simplify the deployment and management of extremely dense wireless cellular networks. SDN can programmatically decouple network architectures from infrastructure, thus making it easier for deploying new applications and services, as well as for tuning network policy and performance. SDN enables distribution of data-plane rules over multiple, low-cost network switches, hence reducing the scalability of the packet gateway and enabling flexible handling of data traffic over the cellular network. This tutorial provides a comprehensive review of current and future SDN-based approach to solve these problems.

Tutorial 2, Symposium Space, Raiosha
- Advances in Reducing Web Response Time
- In recent years, web surfing is one of the most common and popular service provided on the Internet. The ratio of dynamic objects generated when executing programs, e.g., JSP and Ajax has increased, and the servers providing each object have been diversified, e.g., objects of advertisements are obtained from dedicated servers. Therefore, the objects that construct one website have been diversified, and the complexity of communication pattern generated at web browsing has continued to increase. As a result, the web response time, i.e., the waiting time until webpages are displaied at browser, has been increased. For example, when browsing about 1,000 most popular webpages from Tokyo, the response time of 50% webpages was more than 4 seconds. This tutorial gives an overview of various advanced techniques accelerating web response time. First, I abstruct the recent web technologies including the fundamental bodies, e.g., HTML and HTTP, and the recent techniques generating dynamic objects, e.g., Ajax, Servlet, and JSP. Next, I give an overview of some recent works investigating what happens in web browsing service, e.g., analyzing the deployment pattern of web objects. Finally, I explain some popular techniques reducing the web response time including CDN and SPDY, and Inlining, as well as the recent ideas reducing the web response time, e.g., Inlining, edge/fog computing, and prefetching.

Tutorial 3, Symposium Space, Raiosha
- New Challenges in Network Optimization
- The recent evolution of communication networks has induced new challenges in mixed-integer network optimization ranging from problem formulation to computational methods. This tutorial covers in detail five of these problems i) the progressive unification of communication networks with information systems (involving storage and processing) leads to combined routing design - capacitated facility/hub location models where digital objects replace physical goods, introduction of delay-awareness and other temporal constraints (waiting time, replenishment time, etc.), ii) in the same context, the design of resilient network infrastructure can't be designed anymore independently of end-point (content servers, caches) properties and information spatio-temporal distribution properties leading to re-consider classical network resource optimization problems, iii) the expansion of communication networks to heterogeneous environments and running conditions requires incorporating uncertainty in demands and topology parameters in order to formulate robust counterpart of combined network and routing design problems, iv) virtual data centers enable flexible allocation of capacity to serve customer demands by aggregating physical resources taken out of distributed resource pools accessible by customers via dedicated gateways, the corresponding optimization problem can be modeled by combining the three-level capacitated facility location with a flow routing problem, and v) finally, and for more challenging, as optics added a spectral dimension to spatial routing, information adds a semantic dimension to spatial routing (both dimensions having large impact on scale), leading in turn to introduce categorical constraints. In the second part of this tutorial we detail their implications in terms of computational methods and techniques when solving large-scale problems.

- 1-1 Real Haptics-Blossom Technology in 21st Century
- Out of our five senses, auditory sense and visual sense could be artificially transmitted, and reproduced at a remote place. Telephones enable us to communicate with friends at a remote place, and a television broadcasts live-music at foreign countries. However, the sense of touch obtained by pushing, grasping or rubbing objects, has not become transmittable up until quite recently. Keio University Haptics Research Center has succeeded in transmitting the sense of touch to a remote place for the first time in the world. This novel technology is considered to be applied for tactile communication or tactile broadcasting. In addition, its technology is thought to revolutionize the industrial field or medical welfare field. Keio University Haptics Research Center is conducting research and development in order to make it immensely user-friendly.

- Koike Laboratory has proposed and secured basic patents for a variety of innovations: world-leading graded index plastic optical fiber (GI-POF), highly scattered optical-transmission (HSOT) polymers, zero-birefringence polymers, and super-birefringent films. Utilizing these core technologies that are based on the essential principles of light, the Keio Photonics Research Institute (KPRI) is exploring possible applications of polymers in the field of photonics by elucidating their fundamental mechanisms, in an attempt to discover new functions. For example, to optimize the characteristics of ultra high-speed GI-POF (highly flexible, difficult to break, and easy to handle), we are engaged in a series of development processes, ranging from materials design to manufacturing techniques. The Koike Laboratory is not just improving the performance of different kinds of polymer components; it is also working on a "total design" for new and innovative, ultra high-definition (HD) liquid-crystal displays (LCDs).

Keynote speeches
- Talk by presider
- How Optical Technologies Can Compensate the Imminent Demise of Moore's Law?
- The recent advent of hyper-giant content providers and envisaged SDN services are promoting a network paradigm shift. The traffic characteristics of individual users are becoming more diversified. A super-high definition quality ultra-large bandwidth video broadcast experiment is expected in 2016 in Japan. To create nationwide video delivery networks, new transport modes such as optical circuit switching or optical flow switching can be applied in the future. The demand for agility in optical layers will also be needed.
Given that traffic increase is over-running the advances in Silicon technology, optical technologies appear to play more and more critical roles. Most optical switching schemes are transparent to the bitrates of the optical signals, which is completely different from electrical switching systems. In addition, the power consumption of optical switching, W/bit, is much smaller than that of electrical systems and hence large bandwidth and low power consumption switching systems will be possible. To develop next generation networks, extension of node throughput is critical, which can be achieved by exploiting optical technologies. The presentation discusses technologies that are expected to play an important role soon, which includes recent advances in the development of ultra large scale optical switches for intra datacenter application and cost-effective large-scale optical transport nodes. - Towards 5G: On Network Softwarisation
- The telecom industry keeps reinventing itself. Soon, the world will be experiencing the 5th generation mobile networks (5G), also referred to as beyond 2020 mobile communication systems. Major obstacles to overcome in 5G systems are principally the highly centralized architecture of mobile networks along with the static provisioning and configuration of network nodes built on dedicated hardware components. This has resulted in lack of elasticity and flexibility in deployment of mobile networks; rendering their run-time management costly, cumbersome and time-consuming. Software Defined Networking, Network Function Virtualization, and Cloud Computing, along with the principles of the latter in terms of service elasticity, on-demand features, and pay-per-use, could be important enablers for various mobile network enhancements, to specifically virtualize and decentralize mobile networks using general-purpose COTS (commercial of the shelf) hardware. For this purpose, different requirements have to be met and numerous associated challenges have to be subsequently tackled. This talk will touch upon the recent trends the mobile telecommunications market is experiencing and discuss the challenges these trends are representing to mobile network operators. To cope with these trends, the talk will then showcase the feasibility of on-demand creation of cloud-based elastic mobile networks, along with their lifecycle management. The talk will introduce a set of technologies and key architectural elements to realize such vision, turning end-to-end mobile networking into software engineering.

Invited speech, Symposium Space, Raiosha:
- Building efficient network dataplanes in software
- In this talk we give a survey of solutions -- and especially, discuss the underlying design principles -- that we developed in recent years to achieve extremely high packet processing rates in commodity operating systems, for both bare metal and virtual machines.
By using simple abstractions, and resisting the temptation to design systems around performant but constraining assumptions, we have been able to build a very flexible framework that addresses the speed and latency communication requirements of both bare metal and virtual machines up to the 100 Gbit/s range. Our goal is not to provide the fastest framework in the universe, but one that is easy to use and rich of features (and still, amazingly fast), thus taking away concerns on the dataplane's speed from (reasonable) network applications.
Our NETMAP framework, opensource and BSD licensed, runs on 3 OSes (FreeBSD, Linux, Windows); provides access to NICs, host stack, virtual switches and point-to-point channels (netmap pipes), running between 20 and over 100Mpps on software ports, and saturating NICs with just a single core (reported up to 45 Mpps on recent 40G nics); achieves bare-metal speed on VMs thanks to a virtual passthrough mode (available for Qemu and bhyve); and can be used with no modifications by libpcap clients.

Invited speech, Symposium Space, Raiosha
- Towards Information-driven Networks: Research Challenges and Perspectives
- The functionality of the Internet has been since more than 30 years mainly confined to destination-based packet routing (reachability function) along logical communication channels identified by their (destination) address / network locator (connectivity function). However, this shared infrastructure is mainly used nowadays for information exchanges (distribution function) whilst data access remains invariably coupled to the communication channel, in particular, its location and identification. To better accommodate the distribution/exchange of information while accounting for its inherent dynamic and uncertainty, the overlay, the peer-to-peer and the named-data routing model have been/are under investigation.
In this talk, we identify their potentials and limits but also the lessons learned from past experience in designing such models. Taking a complex systems perspective, this talk proposes then new routing paradigms and schemes that account for the distributional properties of information/data objects, and the evaluation of their performance. Knowing that the user utility would be mainly driven by information-related criteria and metrics, the main challenge becomes whether one can combine the maximization of its utility function with the minimization of the network-related cost? The problem space does not limit however to the optimization of resource consumption/costs or user utility function. It involves a functional transformation that was not technologically possible at the first stage of the Internet development when the TCP/IP communication stack had been elaborated. From this perspective, information-driven networking questions more the design of the Transmission Control Protocol (TCP) and its association to the logical communication channels it emulates rather than the (application-level) data segmentation it provides. Many challenges remain thus to be addressed along this evolution, in particular, concerning the forwarding plane and its scaling properties. In this respect, information-driven networking opens a fundamental question: beyond circuit- and packet- switching, which forwarding paradigm fits best information exchanges?
