Multicriteria Breadcrumbs Scoping: Multiple Constraint-Based Distribution Methods of In-Network Guidance Information in Content-Oriented Network

Lately, network usage has been dominated by content distribution, and hence, content oriented network (CON) has attracted much attention. In CON, however, we encounter a scalability problem regarding content acquisition, particularly in large-scale networks composed of multiple domains, because the total amount of content is much larger than the number of network nodes. CON requires a more scalable routing scheme than the traditional IP routing. We have proposed a breadcrumbs-based architecture to establish highly scalable content routing for the content-oriented paradigm. In this paper, we consider another novel approach for controlling guidance (routing) information. We propose a breadcrumbs-scoping (BC-scoping) framework that manages the distribution scope of guidance information according to some criteria. First, we propose BC-scoping on domain, which limits the distribution scope of guidance information within domains according to a hierarchical network structure. It promotes intradomain content acquisition and prevents the occurrence of cross-domain BC trails, because intradomain content acquisition is preferred, both technically and economically. Second, we consider the use of multiple criteria simultaneously with this framework when the criteria are independent of each other. Specifically, we propose BC-scoping on domain and popularity as a practical example of BC-scoping on multiple-criteria. For both of the proposed methods, we show the effectiveness through extensive computer simulation.
