Survey on Caching Approaches in Information Centric Networking

Journal of Network and Computer Applications, 2015

Information Centric Network (ICN) is increasingly becoming the alternative paradigm to the traditional Internet through improving information (content) dissemination on the Internet with names. The need to reduce redundancy and frequent access to a host (provider of information) has raised an alternative of a man-in-middle concept of ICN. This has necessitated the introduction of some ICN popular architectures (such as Named Data Network (NDN), Content Centric Network (CCN), to name a few) to manage the salient advantages incorporated in ICN. Despite all efforts and issues in naming, security, routing and mobility, power consumption; caching has become the leading variable to fully actualize the future Internet dream by carefully solving the problems in frequency and recency (in objects). Determining what part of the content is to be cached? When is the most appropriate time for caching? How would the object be cached (placed and replaced) and also what path would the object be cached? Thus, this paper span through some selected ICN architectures and projects to investigate and suggest forms of caching in minimizing the total bandwidth consumption, enhanced Delivery of Service (DoS), reduced upwards and downward streaming. In conclusion, pointing out some of the future probable ways to improve caching in ICN. This survey also highlighted the top sensitive issues that influence the active deployment of caches in ICN through recency, frequency, content size, cost of retrieval and coordination, update in caches and replacements. Several cache characteristics were further presented in ways that would improve cache techniques, deployments as research suggestions for content placement, replacement and quick scan on nodes on and off-path of the network.

Cache-skip approach for information-centric network

2016

Several ICN cache deployment and management techniques have since been using the Web management techniques to manage information sharing and better cache-hit ratio.Leave Copy Down, Leave Copy Everywhere and Probabilistic cache managements have gained more attention. However, with Leave Copy Everywhere being the initial design specification in ICN proposal, several research issues of content manageability have posed a threat of particularly content and path redundancy.This paper presents an extensive simulation analysis of the popular cache management techniques by subjecting the concepts into different network topologies to investigate the prospect of extending and proposing a new form of cache management in ICN known as Cache-skip. Cache-skip use the consciousness of time of request, network size and Time Since Birth (TSB) and Time Since Inception (TSI) to carefully dedicate the positions of caching to benefits hit rates and less network stress as a form to efficiently utilize the ...

Caching and Data Routing In Information Centric Networking (ICN): The Future Internet Perspective

Information Centric Networking (ICN) is becoming an important direction of the future internet architecture research. Different ICN architectures like PSIRP, NetInf, PURSUIT, CCN, DONA, and NDN have been proposed with the aim of moving from the current host-to-host communication model to a content-centric communication model. Caching and data routing are among the most significant properties of ICN features which improves network efficiency and content distribution performance by satisfying user requests with cached content. New characteristics of ICN caching include the Internet to be transparent to applications, ubiquitous in-network caching (caching contents in routers in a granularity based-level different from the current Internet architecture which cache contents in file-level. This paper describes in-depth, the concepts of caching and data routing in ICN by providing a comprehensive survey of a number of cache decision and data routing policies in ICN. The paper provides also the caching and data routing mechanisms in the Named Data Networking (NDN) which is the promising ICN design for the future Internet architecture. In general, by modelling the in-network caching and data routing which will be based on more efficient cache decision and routing schemes, it will have more practical significance in ICN designs for the future Internet architecture.

NECS-based Cache Management in the Information Centric Networking

International Journal of Interactive Mobile Technologies (iJIM)

The Information Centric Networking ICN architectures are proposed to overcome the problems of the actual internet architecture. One of the main straight points of the ICN architectures is the in-network caching. The ICN performance is influenced by efficiency of the adopted caching strategy which manages the contents in the network and decides where caching them. However, the major issue which faces the caching strategies in the ICN architectures is the strategic election of the cache routers to store the data through its delivery path. This will reduce congestion, optimize the distance between the consumers and the required data furthermore improve latency and alleviate the viral load on the servers. In this paper, we propose a new efficient caching strategy for the Named Data Networking architecture NDN named NECS which is the most promising architecture between all the ICN architectures. The proposed strategy reduces the traffic redundancy, eliminates the useless replication of ...

PopCache: Cache More or Less Based on Content Popularity for Information-Centric Networking

Due to a mismatch between downloading and caching content, the network may not gain significant benefit from the sophisticated in-network caching of information-centric networking (ICN) architectures by using a basic caching mechanism. This paper aims to seek an effective caching decision policy to improve the content dissemination in ICN. We propose PopCache-a caching decision policy with respect to the content popularity-that allows an individual ICN router to cache content more or less in accordance with the popularity characteristic of the content. We propose an analytical model to evaluate the performance of different caching decision policies in terms of the server-hit rate and expected round-trip time. The analysis confirmed by simulation results shows that PopCache yields the lowest expected round-trip time compared with three benchmark caching decision policies, i.e., the always, fixed probability and path-capacity-based probability, and PopCache provides the server-hit rate comparable to the lowest ones.

Performance evaluation of caching policies in NDN - an ICN architecture

2016 IEEE Region 10 Conference (TENCON), 2016

Information Centric Networking (ICN) advocates the philosophy of accessing the content independent of its location. Owing to this location independence in ICN, the routers en-route can be enabled to cache the content to serve the future requests for the same content locally. Several ICN architectures have been proposed in the literature along with various caching algorithms for caching and cache replacement at the routers en-route. The aim of this paper is to critically evaluate various caching policies using Named Data Networking (NDN), an ICN architecture proposed in literature. We have presented the performance comparison of different caching policies naming First In First Out (FIFO), Least Recently Used (LRU), and Universal Caching (UC) in two network models; Watts-Strogatz (WS) model (suitable for dense short link networks such as sensor networks) and Sprint topology (better suited for large Internet Service Provider (ISP) networks) using ndnSIM, an ns3 based discrete event simulator for NDN architecture. Our results indicate that UC outperforms other caching policies such as LRU and FIFO and makes UC a better alternative for both sensor networks and ISP networks.

Exploring Off-Path Caching with Edge Caching in Information Centric Networking

In the last couple of years, Information Centric Networking (ICN) has gained momentum as increasing number of patches for various issues (like mobility, security, availability etc.) have transformed TCP/IP into a complex and delicate network architecture. Among many core functionalities of ICN, pervasive in-network caching has potential to play an indispensable role in ameliorating the overall network performance. The paper thus aims to empirically evaluate the performance of some of the existing in-network caching techniques and also proposes a new caching technique. More specifically, in the first part of the paper, it is empirically proven that off-path caching performs the best, as compared to on-path and edge caching in terms of hit rate, average retrieval delay, cache diversity and external traffic over expensive links. In second part of the paper, EDOP caching has been proposed as hybrid caching strategy that couples effectively off-path caching with edge caching. The results exhibit that EDOP caching effects significant improvement in average retrieval delay for the top most popular contents while inducing marginal trade-off in other relevant performance metrics.

A Comparative Survey On Different Caching Mechanisms In Named Data Networking (NDN) Architecture

Journal of Emerging Technologies and Innovative Research, 2019

The Named Data Networking (NDN) is the forthcoming internet architecture which is developed and tested as an alternative to the standard IP architecture. It is acquired from Information Centric Networking (ICN). The data accessing depends on the name of the data content so that it is not depended on any particular server or location. Each router in the network stores particular data as cache based on different policies like Least Frequently Used (LFU), Universal Caching (UC), First in First out (FIFO), Least Recently Used (LRU), and etc., Caching process in NDN is the main function, where the availability of data to the user is based on getting and storing the appropriate required data in the storage area. So that it must be available whenever the user request for it. Due to this function, it is the major area to be concerned and researched in the NDN architecture. This survey is done on several caching strategies, their algorithm, caching types, their advantages and issues. Based on the survey work, various cache methods are compared based on different criteria. Different challenges in their works are analyzed, and a proposal based on these works is given at the end of this paper.

On the cache performance of the information centric network

2013 INTERNATIONAL CONFERENCE ON COMPUTING, ELECTRICAL AND ELECTRONIC ENGINEERING (ICCEEE), 2013

The current Internet model has proved more sustainable then the provisioned capacity at the time when the architecture was designed. The voluminous growth of traffic over the Internet has brought challenges for the exiting networking architecture. The information centric paradigm appears to offer efficient solution towards content dissemination model. It is a content-focused networking paradigm rather than host-to-host communication. Caching is one of the major components of information centric networks. This paper is intended to explore the impact of cache on critical attributes of networks. We have made a comparative analysis of in-network and edge network caching mechanism using network simulation. The results proved that in-network caching mechanism is far better than network edge caching with improved throughout, increase link capacity to avoid congestion.

A Constructive Review of In-Network Caching: A Core Functionality of ICN

Over the years, caching has been leveraged (and established) as an add-on functionality to enhance network performance. However, Information Centric Networking (ICN) conceives caching at network layer (i.e. beyond the premise of end-to-end principle) thereby making it one of the core functionalities. Further, ICN advocates named-content (another core functionality) that allows content-consciousness within networks. Together the two functionalities result in content-aware ubiquitous in-network caching that has received significant attention of researcher all-around. The aim of this paper is to probe in depth and review some of the work done pertaining to in-network caching in ICN, in order to understand their aims, assumptions, approaches, simulation setups used, network topologies exploited, traffic pattern fed-in, performance metrics used, parameter(s) tuned-in to optimize the performance and the significance of the results obtained by the researchers. The paper also lists out advantages of in-network caching, related issues, factors that affect in-network caching and relevant performance metrics. The paper intends to assist researchers who are searching ways to put-forward (an acceptable) proof of their ideas.
