ABSTRACT
Video streaming is one of the key factors in the increased consumption of bandwidth on the Internet. Content delivery networks are being deployed as a solution to avoid scalability problems but they are excessively complex in part because of the underlying network architecture. The Future Internet (FI) proposals are centered on providing an evolutive or disruptive path to evolve the underlying network architecture. Among these proposals, the Software-Defined Networking (SDN) initiative is a distinctive approach to introduce new mechanisms to current networks. In parallel, the Internet of Things (IoT) faces the heterogeneity present in today’s mobile and sensorized world while trying to minimize power consumption. Some of these FI architectures have focused on separating identifiers from locators. At the same time, the Information-Centric Networking (ICN) paradigm employs intermediate network elements for content distribution while also separating identifiers from locators. Thanks to SDN, the endpoints of content delivery can remain unchanged while adopting initiatives such as ICN to efficiently and effectively address content delivery in current networks. While SDN and IoT are already envisioned as coming in the near future, ICN is the key to combine them. This last fact is increasingly true for video streaming over the IoT.
