Anchor-less producer mobility in ICN

Mobility has become a basic premise of almost any network communication, thereby requiring a native integration into next generation 5G networks. Despite the numerous efforts to propose and to standardize effective mobility management models for IP, the result is a very complex, poorly flexible set of mechanisms not suitable for the design of a radio-agnostic 5G mobile core. The natural support for mobility, security and storage offered by ICN (Information-Centric Networking) architecture, makes it a good candidate to define a radically new solution relieving limitations of traditional approaches. If consumer mobility is supported in ICN by design in virtue of its connectionless pull-based communication model, producer mobility still appears to be an open challenge. In this work we describe an initial proposal for an anchorless approach to manage producer mobility via Interest Updates/Notifications in the data plane, even in presence of latency-sensitive applications. We detail the different operations triggered by producer movements and position our contribution in the context of existing alternatives, by discussing either user performance and network metrics.
