Information-centric networking (ICN) and software defined networking (SDN) are two novel network paradigms that the networking community is actively investigating. Because of their salient features, there are increasing attempts to integrate ICN and SDN. In this paper, we show how a recently proposed future Internet architecture (called CoLoR) makes it efficient to integrate SDN and ICN. In particular, we show how CoLoR reduces the flow setup delay, the number of flow setup requests, and the number of flow entries.
In this paper, we analyze the security threats of a newly proposed future Internet architecture called CoLoR. In particular, we describe how CoLoR defends against the most prevalent attacks existing in both the current Internet and some recently proposed information-centric networks such as named data networking (NDN). We also present attacks that are specific to CoLoR and discuss how to deal with them. Through our analysis, we find that CoLoR is more secure than both the current Internet and NDN.
Network operators desire to obtain accurate evaluations of the traffic matrices of their networks because they are critical inputs to many network functions such as traffic engineering, capacity provisioning and anomaly detection. Under the current Internet architecture, however, it is extremely challenging to precisely measure the traffic between an ingress and egress node pair. In this paper, we argue that a future Internet should make it easy for network operators to be aware of the accurate traffic matrices of their networks in an efficient and timely manner. In particular, we present the requirements for TM estimation and the corresponding implications on the future Internet architecture. Based on these implications, we then present a future Internet architecture that makes it easy to accurately, efficiently, and timely estimate traffic matrices. We also present numerical results to demonstrate the performance of the architecture in estimating traffic matrices.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
