A Hybrid Approach for Name Resolution and Producer Selection in Information Centric Network
Lijun Dong, Guoqiang Wang · 2018 International Conference on Computing, Networking and Communications (ICNC) · 2018
The Information Centric Networking is centered around the content name resolution, content request forwarding and content delivery. With the emerging IoT applications, in which a content data may have multiple producers, the content name resolution needs to incorporate the producer selection based on the user's criteria or proactively into the system. The currently existing name resolution approaches in ICN have two major categories: the name based routing approach that combines the name resolution and routing of content request as one process and the standalone approach that separates from the routing of the content request. Both categories of approaches do not work well for the new producer selection feature. The paper proposes a hybrid name resolution approach, in which each content has a Home Node located in ICN routers. The Home Node maintains all the necessary information for producer selection while acts as the virtual content producer to the rest of the network. A classification model is introduced to determine how a Home Node is specified for a newly published content. The paper compares the new approach with the existing ones in the performances of control message overhead and latency. The proposed approach outperforms in different settings of simulations.
