A novel overlay architecture for Information Centric Networking

Abstract

Information Centric Networks (ICN) has emerged as a new Internet paradigm where the users are being provided seamless access to contents rather than the host as in classical approach. For ICN realization, the current Internet requires architectural changes. These changes must be incorporated such that existing applications continue running without any difficul ties. In this paper, we introduce a novel ICN architecture, called Overlay Information Centric Networks (O-ICN), which separates the data plane from the control plane activities of the network. Unlike the usual ICN architectures, in our approach naming and routing (control plane) functionalities have been segregated from the caching (data plane) functionality at each ICN router. We introduce a new module called an ICN Manager which is an extended version of Domain Name System (DNS) server and per forms name resolution along with routing functionalities for ICN type of requests as well as the normal DNS resolution for non ICN type of requests. The O-ICN architecture can be deployed incrementally over the current Internet and can operate both as ICN and non-ICNllegacy network simultaneously. This can also be implemented both in Software Defined Networks (SDN) as well as non-SDN networks without much modifications. The proposed architecture provides benefits in terms of simplification of network management, vendor independent solution, better use of network resources in terms of bandwidth and delay, and reduction of deployment/operational cost of the network.

Path Segmentation-Based Hybrid Caching in Information-Centric Networks

“…The existing Internet architecture is entrenched and challenged to change radically, and so the new architecture should be deployed as an overlay network to accommodate existing IP networks [20]. In this paper, we consider an IP-compatible ICN network architecture shown in Figure 1.…”

Routing algorithm design of satellite network architecture based on SDN and ICN

“…The main methods of ICN message recognition can be divided into two categories: one method is to identify ICN messages by existing protocol‐specific identifiers (such as port number, MAC address, IP reservation, etc.). For example, in Shailendra et al, the authors identified the ICN request by using a reserved bit of the TCP header and added an ICN sublayer to carry the data of the ICN message at the head of the application layer packet. In Vahlenkamp et al, the authors use a specific IP address to identify an ICN‐based AS domain.…”

Coexistence of ICN and IP Networks: An NFV as a Service Approach

“…For instance, Shailendra et al [17] design an Overlay Information Centric Networks architecture that separates the data plane from the control plane. The control plane contains both naming and routing, while the data plane contains innetwork caching.…”
