Information-Centric Multilayer Networking: Improving Performance Through an ICN/WDM Architecture

Abstract

Information-centric networking (ICN) facilitates content identification in networks and offers parametric representation of content semantics. This paper proposes an ICN/WDM network architecture that uses these features to offer superior network utilization, in terms of performance and power consumption. The architecture introduces an ICN publish/subscribe communication approach to the wavelength layer, whereby content is aggregated according to its popularity rank into wavelength-size groups that can be published and subscribed to by multiple nodes. Consequently, routing and wavelength assignment (RWA) algorithms benefit from anycast to identify multiple sources of aggregate content and allow optimization of the source selection of light paths. A power-aware algorithm, maximum degree of connectivity, has been developed with the objective of exploiting this flexibility to address the tradeoff between power consumption and network performance. The algorithm is also applicable to IP architectures, albeit with less flexibility. Evaluation results indicate the superiority of the proposed ICN architecture, even when utilizing conventional routing methods, compared with its IP counterpart. The results further highlight the performance improvement achieved by the proposed algorithm, compared with the conventional RWA methods, such as shortest-path first fit.Index Terms-Information-centric networking, traffic engineering, multilayer network architecture, routing and wavelength assignment.

Service-based, Multi-Provider, Fog Ecosystem with Joint Optimization of Request Mapping and Response Routing

“…Furthermore, although strands of the work above are at the granularity of services, they do not utilize service popularity metrics to estimate the demand per service and utilize it in planning resource allocations. However, existing work in DC networks such as [23] show that considering service popularity for demand prioritization offers significant gains.…”
