In this work we investigate Named Data Networking's (NDN's) architectural properties and features, such as content caching and intelligent packet forwarding, in the context of Content Delivery Network (CDN) workflows. More specifically, we evaluate NDN's properties for PoP (Point of Presence) to PoP and PoP to device connectivity. We use the Apache Traffic Server (ATS) platform to create a CDN-like caching hierarchy in order to compare NDN with HTTPbased content delivery. Overall, our work demonstrates that several properties inherent to NDN can benefit content providers and users alike through in-network caching of content, fast retransmission, and stateful hop-by-hop packet forwarding. Our experimental results demonstrate that HTTP delivers content faster under stable conditions due to a mature software stack. However, NDN performs better in the presence of packet loss, even for a loss rate as low as 0.1%, due to packet-level caching in the network and fast retransmissions from close upstreams. We further show that the Time To First Byte (TTFB) in NDN is consistently lower than HTTP (~ 100ms in HTTP vs. ~ 50ms in NDN), a vital requirement for CDNs. Unlike HTTP, NDN also supports transparent failover to another upstream when a failure occurs in the network. Finally, we present implementation-agnostic (implementation choices can be Software Defined Networking, Information Centric Networking, or something else) network properties that can benefit CDN workflows.Named Data Networking (NDN) [1] is a future Internet architecture that focuses on content distribution and utilizes content names for most in-network operations such as packet forwarding and content caching. The synergy between CDNs and the NDN architecture is that both aim to optimize content delivery. Further, CDNs and NDN both utilize similar

Abstract-ln this paper, portable clouds are devised after observing similarities between providing the Internet access to users onboard vehicles and to users in remote resources-constrained communities. ln both cases, a gateway connection to the core network is bandwidth limited and unreliable. Portable clouds are intended to provide applications and services in scenarios even when the gateway link is not available at all for extended periods of time. Portable clouds exploit cache to store contents and provide computing resources locally while the applications are modified to facilitate acceptable QoE. The cache is updated infrequently and only when a fast connection becomes available, or when the contents are physically delivered to the cache using a memory medium.

“…In [7], authors have performed an evaluation of Named-Data Networking and Content Distribution Networks (CDNs) in a rural community wireless mesh network (CWMN). Their results show that the CDN approach achieves better performance in terms of content delivery time; however, due to the in-network caching, NDN generated less cache misses, leading to a lower bandwidth usage.…”

The emerging paradigm of Information-Centric Networking is an exciting field of research, opening opportunities in many areas, such as forwarding strategies, caching placement policies, applications (e.g. video streaming and instant messaging), to name a few. In this paper, we address the mobility aspect of ICN, as well as how it performs in tactical wireless ad hoc environments. In this paper, we present results from a simulation study that investigates the performance of Named Data Networking, an instantiation of ICN, in such environments. We perform a series of simulations based on ndnSIM studying different mobility scenarios. Our simulations show that even in the short-term absence of the producer, consumers can still achieve better file retrieval when caches are used. As an effort to increase the cache diversity and have a better utilization of the Content Store we study probabilistic LRU. Furthermore, we compare the performance of our NDN network with a TCP based approach, using OLSR routing protocol, discussing advantages and disadvantages of each approach.
