An efficient mechanism for establishing IP connectivity in next‐generation networks

The changes in the communication paradigm envisioned for next‐generation networks (NGNs), with peer‐to‐peer/symmetric attachments gaining momentum and two Internet Protocol (IP) versions coexisting, will pose new challenges to mobile communication networks. Traditional IP auto‐configuration mechanisms will not work properly, since they were designed mostly having in mind a client–server/asymmetric attachment model, they assume a single IP version paradigm, and they target the auto‐configuration of devices only. The IST Ambient Networks (ANs) project has introduced a new concept—the AN—that enables handling every communication entity, either a single device or an entire network, as an AN. This paper describes a new efficient mechanism, named Basic Connectivity (BC) mechanism, for auto‐configuring IP connectivity between attaching ANs. A proof‐of‐concept prototype, experimental results, and theoretical analysis show that BC suites the future networking paradigm and represents a solution more efficient than the current trial‐and‐error mechanism for auto‐configuring IP connectivity.
