“…In this paper, we consider MobilityFirst [3], [7], a mobility-centric architecture that supports large-scale, efficient and robust network services with mobility as the norm. In MobilityFirst, we associate every endpoint with a global unique identifier (GUID), which is decoupled from its network address or location, and rely on a dynamic global name resolution service (GNRS), such as those in [8], [9], [10], [11], to track and resolve the mapping between GUID and its network address(es). MobilityFirst aims to support smooth mobile content delivery exploiting real-time GNRS updates and queries.…”

The prevalence of mobile devices especially smartphones has attracted research on mobile content delivery techniques. In this paper, we propose to take advantage of the storage available at wireless access points to bring content closer to mobile devices, hence improving the downloading performance. Specifically, we propose to have a separate popularity based cache and a prefetch buffer at the network edge to capture both longterm and short-term content access patterns. Further, we point out that it is insufficient to rely on a device's past history to predict when and where to prefetch, especially in urban settings; instead, we propose to derive a prediction model based on the aggregated network-level statistics.We discuss the proposed mobile content caching/prefetching method in the context of the MobilityFirst future Internet architecture. In MobilityFirst, when mobile clients move between network attachment points (e.g., Wi-Fi access points), their network association records are logged by the network, which then naturally facilitates the network-level mobility prediction. Through detailed simulations with real taxi mobility traces, we show that such a strategy is more effective than earlier schemes in satisfying content requests at the edge (higher cache hit ratios), leading to shorter content download latencies. Specifically, the fraction of requests satisfied at the edge increases by a factor of 2.9 compared to a caching only approach, and by 45% compared to individual user-based prediction and prefetching.

“…A key implication of our findings is that name-based routing approaches in their puristic form may be better suited for content alone, but need to be augmented with addressingassisted approaches such as DNS, Mobile IP, or a nextgeneration name resolution service [49] in order to serve as a general-purpose replacement for the TCP/IP Internet. Our findings also show the important differences between device and content mobility, as well as the emerging importance of the strategy layer [28,55] in content-oriented architectures.…”

This paper presents a quantitative methodology and results comparing different approaches for location-independent communication. Our approach is empirical and is based on real Internet topologies, routing tables from real routers, and a measured workload of the mobility of devices and content across network addresses today. We measure the extent of network mobility exhibited by mobile devices with a homebrewed Android app deployed on hundreds of smartphones, and measure the network mobility of Internet content from distributed vantage points. We combine this measured data with our quantitative methodology to analyze the different cost-benefit tradeoffs struck by location-independent network architectures with respect to routing update cost, path stretch, and forwarding table size. We find that more than 20% of users change over 10 IP addresses a day, suggesting that mobility is the norm rather than the exception, so intrinsic and efficient network support for mobility is critical. We also find that with purely name-based routing approaches, each event involving the mobility of a device or popular content may result in an update at up to 14% of Internet routers; but, the fraction of impacted routers is much smaller for the long tail of unpopular content. These results suggest that recent proposals for pure name-based networking may be suitable for highly aggregateable content that moves infrequently but may need to be augmented with addressing-assisted approaches to handle device mobility.

“…Several publications [10,11,12,13,14,15] discuss deploying DNS over an overlay network that uses a distributed hash table (DHT) to reduce the load on individual servers and thus provide higher scalability and better fault tolerance. These papers target the traditional DNS system in the Internet, and thus focus on planet-level scalability.…”

A key problem in all name resolution protocols today is that no one protocol performs well across all network architectures. In addition, DNS, the most widespread solution today, depends on a static and connected network layer and faces significant challenges in dynamic wireless networks. We introduce FERN (Federated Extensible Resolution of Names), the first framework designed to enable efficient name resolution across heterogeneous systems operating in dynamic or static networks. FERN organizes nodes into name resolution groups and allows each group to perform name resolution independently and in a manner best suited for that group. FERN arranges these name resolution groups into a hierarchy and allows these groups to communicate efficiently, discover each other's presence, and resolve each other's names. We demonstrate the flexibility and interoperability of FERN by deploying and evaluating it across heterogeneous environments, including a MANET, an infrastructure-based wireless network, and the Internet. We show that FERN performs at least as well as DNS, and yet extends name resolution to networks in which DNS is inadequate.
