Augmented and virtual reality (AR and VR) are entering the consumer market, and attracting substantial at- tention from content creators. However, delivering AR and VR experiences using existing IP networks presents significant challenges that tend to force creators into “stovepipe” solutions, in contrast with the openness of the early World Wide Web, which led to its widespread content revolution. Taking advan- tage of multiple network interfaces and providing resilience to intermittent connectivity in mobile scenarios are difficult, as is handling trust for experiences built up from the content of heterogeneous providers. Additionally, streaming AR and VR content, including video components, must be user-navigable across multiple dimensions. This paper explores opportunities for an augmented reality web using Named Data Networking (NDN), a proposed future Internet architecture in which the network forwards intrinsically secure data packets directly based on application-defined names. By providing web semantics at packet granularity, NDN enables the success of the web to be pursued for low-latency, high-granularity, and context-dependent media in AR. The paper outlines emerging media types that could be part of a new AR browsing experience, briefly introduces NDN, describes benefits the architecture should provide via an example browser design, and enumerates related open research challenges.
