Node-oriented Internet Protocol: A novel concept for enhancement of mobility and multi-homing in Future Internet

摘要

Mobility and multi-homing are closely related and mainly issues of the used IP addressing scheme. Novel addressing schemes that separate node identification and location are promising concepts to tackle the named issues. However, current approaches that make use of the address separation concept offer, among others, insufficient capabilities to select one or multiple network interfaces for a certain communication process, e.g. to enable load balancing. Therefore, we propose a novel approach called Node-oriented Internet Protocol (NIP). NIP adapts the address separation concept, introduces a novel three-tuple addressing scheme that adds an interface ID and enables network nodes to select sets of network interfaces to be used for communication sessions. Our work includes basic concepts for mapping system, schemes for packet forwarding, mechanisms for mobility and multi-homing support and strategies to ensure backwards compatibility. Building on that, the NIP concept enhances multi-homing and mobility capabilites with new functionalities in comparison to known approaches, especially referred to interface selection and bandwidth aggregation.
