Versatile Routing and Self-Certifying Features Support for Secure Mobility in eXpressive Internet Architecture

Integrating mobility and security in the network layer has become a key factor for Future Internet Architecture(FIA). This paper proposes a secure mobility support mechanism in e Xpressive Internet Architecture(XIA),a new FIA currently under development as part of the US National Science Foundation's(NSF) program. Utilizing the natural features of ID/locator decoupling and versatile routing in XIA, a general mechanism to support host mobility is proposed. Exploiting the self-certifying identifier, a secure binding update protocol to overcome the potential threats introduced by the proposed mobility support mechanism is also given. We demonstrate that our design in XIA outperforms IP based solutions in terms of efficiency and flexibility. We also outline our initial design to illustrate one derivative benefit of an evolvable architecture:mobility support customizability with no sacrifice of architectural generality.

Mapping prediction with recurrent neural networks for future LISP enabled networks

Locator/identifier separation paradigm(LISP)is an emerging Internet architecture evolution trend that decouples the identifier and location of an entity attached to the Internet.Due to its flexibility,LISP has seen its application in various fields such as mobile edge computing,and V2X networks.However,LISP relies on a DNS-like mapping system to associate identifiers and locations before connection establishment.Such a procedure incurs an extra latency overhead and thus hinders the adoption of LISP in delay-sensitive use cases.In this paper,we propose a novel RNN-based mapping prediction scheme to boost the performance of the LISP mapping resolution,by modeling the mapping procedure as a time series prediction problem.The key idea is to predict the mapping data regarding services to be utilized by users in edge networks administered by xTRs and proactively cache the mapping information within xTRs in advance.We compare our approach with several baseline methods,and the experiment results show a 30.02%performance gain in LISP cache hit ratio and 55.6%delay reduction compared with the case without mapping prediction scheme.This work preliminarily proves the potential of the approach in promoting lowlatency LISP-based use cases.

The road towards future Internet

Given the emerging problems of today’s Internet,many new Internet architectures have been proposed by the net-working community.In general,the new approaches can be categorized into two types:evolutionary approaches and clean-slate approaches.The representative evolutionary solution is IPv6,while representative clean-slate approaches are NDN(Named Data Networking),MobilityFirst,NEBULA,XIA(Expressive Internet Architecture),and SDN(Software-Defined Networking).A comprehensive survey of these approaches are presented.Additionally,a novel network architecture that we recently proposed:ADN(Address-Driven Networking)is described,which intends to address the challenges faced by today’s Internet via the flexible and innovative utilization of IP addresses.
