Summary NDN forwarding strategies are mainly developed receiver‐driven, where Interest forwarding and Data (content) delivery are controlled from the consumers' viewpoint. The receiver‐driven strategies are greedy by nature and emphasize optimizing the Interest forwarding, which is far from the performance bottleneck as an Interest is of tiny size in compared with a content's size. Thus, optimizing the content delivery can improve the forwarding performance. Moreover, source‐driven optimization of content delivery can alleviate the greedy nature of its counterpart. In this work, a source‐driven forwarding strategy is proposed where the content sources respond to Interest requests in a distributed manner. The content requests hit all the sources, but the sources respond probabilistically such that the content retrieval overhead and latency are minimized. The strategy consents the nearer sources to set a high probability of reacting with the matching content. On the contrary, the distant sources answer with an Offer to save transmission overhead. Besides, a caching strategy is proposed, an integral part of the source‐driven scheme, that caches diverse contents considering the gap between successive copies and content availability while admitting new contents. Next, we extend the source‐driven probabilistic forwarding strategy to operate in SDN‐based NDN architecture. The SDN‐based solution controls the content delivery phase using the global knowledge of NDN cache states. Simulation study conducted using ndnSIM reveals that the proposed forwarding and caching strategy improves user satisfaction and network performance in terms of different performance metrics such as transmission overhead, latency, and cache hit.

“… The extensive simulation of CCJRF-ICN is carried out inside ndnSIM-2.0, a simulator specifically designed for NDN research [8]. The performance of the protocol is compared against state-of-the-art protocols including LCD [9], LCE [10], CL4M [11], ProbCache [12], hash routing [13], CTR [14], co-operative forwarding [15] and multipath forwarding [16]. The protocol shows a significant performance improvement in the range of 5-35% in the context of content retrieval latency, network load, network overhead, CS hit ratio, and mean hop distance compare to state-of-the-art approaches for realistic internet topologies like GEANT, US-26, Euro-28.…”

CCJRF-ICN: A Novel Mechanism for Coadjuvant Caching Joint Request Forwarding in Information Centric Networks

Information centric networking (ICN) shifts the focus of existing internet architecture from host-oriented to content-oriented model by enabling in-network caching and content-based forwarding. These ICN features help to increase network performance by decreasing content discovery delay, content server load, and network congestion. To route a content interest inside network such that content can be fetched with minimal time is a challenging task in ICN. The performance of the ICN routing protocol can be significantly improved if the decisions related to content chunk placement and request forwarding are taken in a cooperative fashion. This paper describes a novel strategy for co-operative caching joint request forwarding in ICN, focusing on decreasing content retrieval latency. To do so, the caching strategy leverages the concept of connected dominating set (CDS) for creating a virtual backbone network to eliminate caching redundancy and reduce content discovery delay. It considers content chunk placement and request forwarding tasks as strongly co-related procedures. It exploits the caching information so that the request is forwarded to a content router (CR) with the maximum likelihood of carrying needed data using the betweenness centrality (BC) of CR. The proposed approach also uses the Markov chain-based model to estimate CS hit likelihood and use it as decisional parameter while forwarding the interest packet. This mechanism helps to fetch the content within the shortest possible time duration. The CCJRF-ICN adopts the Dijkstra's shortest path routing and works in collaboration with the CDS-driven caching joint forwarding mechanism. The simulation study of CCJRF-ICN is done inside ns-3 based ndnSIM-2.0 simulator with performance measures like content store (CS) hit ratio, content discovery delay, mean hop distance, network load, and network overhead. The simulation outcomes demonstrate that CCJRF-ICN outperforms the state-of-the-art strategies for realistic topologies (GEANT, US-26, Euro-28) and shows improvement up to 5-35% against stated performance measures.

Due to the popularity of network applications, such as multimedia, online shopping, Internet of Things (IoT), and 5G, the contents cached in the routers are frequently replaced in Content-Centric Networking (CCN). Generally, cache miss causes numerous propagated packets to get the required content that deteriorates network congestion and delay the response time of consumers. Many caching strategies and routing policies were proposed to solve the problem. This paper presents an alternative solution by designing a query-based routing table update mechanism to increase the accuracy of routing tables. By adding an additional query content in interest packets, our approach real-time explores the cached content in routers and updated the routing table accordingly. This paper uses a general network simulator, ndnSIM, to compare basic CCN and our approach. The results show that our approach improves the response time of consumers and network congestion and is compatible with general forwarding strategies.
