This dissertation presents several content-oriented approaches for efficient data transmission in the future Internet.These approaches leverage known properties of contents in various aspects to facilitate content delivery.Our proposed approaches are grounded in two main techniques: 1) Content-Centric Networking (CCN) architecture and 2) QoS-aware routing with network coding.They are used to address problems in particular parts of the Internet, which can be categorized by location into a core area and an edge area.An increasing amount of content retrieval traffic raises concern about network congestion in the core area of the modern Internet.An effective solution to network congestion is network caching, whose basic principle is to store some contents in the storage close to content requesters so that some requests can be solved locally.Available implementation of network caching is often unnecessarily complicated.It requires complex middleware for content-to-location translation since contents are not natively identifiable to the data plane of routers.Content-Centric Networking (CCN), which is also called Named Data Networking (NDN), is a new architecture for the future Internet that solves this issue by substituting host addresses in packets with content names and using caches of routers as in-network caches.One of major challenges in CCN is how to efficiently utilize the in-network caches which have limited storage.We address this challenge with two
