Named Data Networking (NDN) uses the content name to enable content sharing in a network using Interest and Data messages. In essence, NDN supports communication through multiple interfaces, therefore, it is imperative to think of the interface that better meets the communication requirements of the application. The current interface ranking is based on single static metric such as minimum number of hops, maximum satisfaction rate, or minimum network delay. However, this ranking may adversely affect the network performance. To fill the gap, in this paper, we propose a new multi-metric robust interface ranking scheme that combines multiple metrics with different objective functions. Furthermore, we also introduce different forwarding modes to handle the forwarding decision according to the available ranked interfaces. Extensive simulation experiments demonstrate that the proposed scheme selects the best and suitable forwarding interface to deliver content.

Today's mobile app economy has greatly expanded the types of "things" people can share –- spanning from new types of digital content like physiological data (e.g., workouts) to physical things like apartments and work tools ("sharing economy"). To understand whether mobile platforms provide adequate support for such novel sharing services, we surveyed 200 participants about their experiences with six types of emergent sharing services. For each domain we elicited device usage practices and identified corresponding device selection criteria. Our analysis suggests that, despite contemporary mobile first design efforts, desktop interfaces of emergent content sharing services are often considered more efficient and easier to use –- both for sharing and access control tasks (i.e., privacy). Based on our findings, we outline device-related design and research opportunities in this space.
