MPS: a multipath publish/subscribe model in information-centric network

Abstract

Information-Centric Network ICN provides a brand new architecture of future networks. It can make content retrieval easier and more flexible. Publish/subscribe pub/sub system has gained more and more popularity because of its convenience for users without regard to the source of information or its current position. Currently, many studies focus on pub/sub system in ICN architecture instead of traditional IP-based structure. However, these researches are mainly based on a single-publisher and hierarchical-structure environment which is very different from the reality. In this paper, we propose a multipath pub/sub model named MPS in ICN in order to enhance the performance of data transmission, especially for stream media content. Unlike original ICN forwarding mechanism, we design the Multipath Transmission Protocol with a new component named connection manager to control every multipath connection between subscribers and publishers. Our proposal optimises the system performance in an environment of multi-publisher and general graph. The results of simulation show that our solution improves over 63% in the reliability of information delivery and reduces over 47% in the time of content transmission.
