Realizing IoT & 5G Innovation and Services with SDN/NFV
Jason Yi-Bing Lin

Innovative IoT services such as Tactile Internet, Autonomous Driving and Massive M2M are considered major service offers in the future. These IoT services are characterized by very diverse QoS, security, latency and mobility requirements. Consequently, a more flexible, adaptable network than the existing 4G is required to accommodate and inspire IoT service innovation. For each service innovation, a specific network with the designated QoS, security, latency and mobility features must be provided. Network slicing envisaged by 5G networks will be the answer. SDN/NFV are the key technologies to realize network slicing in 5G. This talk will elaborates on how to devlop SDN/NFV for 5G IoT network slicing.

Sampling Large Networks: Algorithms and Applications

Often times, large networks can be represented as graphs. For example, the Internet topology can be represented as an undirected graph while large logical networks (e.g., Facebook, Twitter,..etc) can be represented as either directed or undirected graphs. For these graphs, characterizing node pair relationships is important for applications such as friend recommendation and interest targeting in online social networks (OSNs). Due to the large scale nature of such networks, it is infeasible to enumerate all user pairs and so sampling is used. In this talk, we show that it is a great challenge even for OSN service providers to characterize user pair relationships when they possess the complete graph topology. The reason is that when sampling techniques (i.e., uniform vertex sampling and random walk) are naively applied, they can introduce large biases, in particular, for estimating similarity distribution of user pairs with constraints such as existence of mutual neighbors. Estimating statistics of user pairs is even more challenging in the absence of the complete topology information, since an unbiased sampling technique such as uniform vertex sampling is usually not allowed, and exploring the OSN graph topology is expensive. To address these challenges, we present asymptotically unbiased sampling methods to characterize user pair properties. We also show potential applications and discuss future research work.

Efficient Information and Influence Diffusion in Communications and Social Networks
Institute of Communications Engineering
Department of Electrical Engineering

For information dissemination, multicast is an efficient technique for point-to-multipoint (P2M) and multipoint-to-multipoint (M2M) communications. Current multicast standard on Internet, i.e., PIM-SM, employs a shortest-path tree to connect the clients in a multicast group. With the emergence of Software-Defined Networks (SDN), flexible routing for traffic engineering now becomes promising, but at the same time, the scalability problem appears to be the major stumbling block during the deployment, especially for multi-tree SDN multicast. In this talk, we will first focus on multicast traffic engineering with reliability for SDN. New optimization problems with approximation algorithms, together with implementation in real SDN for Youtube traffic will be presented.
For influence diffusion, a study in Nature demonstrated that people decisions are indeed affected by social influence passing through Facebook. Nevertheless, the above study does not control the diffusion of social influence. In the second part of this talk, therefore, we will introduce the optimization for diffusion of social influence in online social networks. We will first introduce the diffusion models of social influence and the corresponding hardness results. We will then present the hardness results and approximation algorithms to solve target-oriented influence maximization with frequent patterns. Several innovative social applications based on social influence and their implementation on Facebook will be presented finally.
