LISP Optimisation of Mobile Data Streaming in Connected Societies

Abstract

Mobility mechanisms are key elements of “always connected” smart environments. Since the first mobile IPv4 protocols, the IP mobility solutions have evolved from host mobility to network mobility and migration to IPv6, but there are still use-cases to be covered, especially for redundant multihomed scenarios. Also mobility does not refer only to hosts or individuals, but also to code/applications and to virtual machines. LISP (Locator/Identifier Separation Protocol) can contribute to new solutions for both host mobility and virtual machine mobility (e.g., inside enterprise data centers) by the separation of the identifier and location of a network endpoint. The aim of this paper is to propose a LISP based multihome and load-balanced network architecture for urban environments. Validation is done in an emulated environment for the case of an enterprise with distributed locations, but, furthermore, we extrapolate to other mobile urban scenarios, like the case of providing reliable load-balanced and secured Internet in Public Transportation Systems, with a proposal for an open-source implementation.

Comparative Study Regarding the Surface Roughness of Highly Viscous Flowable Composites After Immersion in Acidic Drinks

“…Our results are in agreement with other studies which showed that the exposure to acidic drinks and food intake induces the chemical dissolution of restorative materials, thus increasing the roughness of the superficial layer. Some studies have shown that a residual surface roughness may induce bacterial plaque retention [19][20][21]. pH of Coca-Cola is very low.…”

Programmable Overlays via OpenOverlayRouter

“…The control module is configured using a static configuration file which is read during boot-up. At run-time, it is possible to modify parts of this configuration remotely thanks to the NETCONF (RFC 6241) module that OOR implements with the libnetconf library 11 . Other major auxiliary modules are described in this section.…”

“…Currently, there are other academic initiatives (e.g., [11]) that are making use of the project for their own research. Furthermore, OOR has helped to discover new research challenges that need to be addressed.…”

“…Among the different options to instantiate overlays, the Locator/ID Separation Protocol (LISP) [7] has gained significant traction among industry and academia [5], [6], [8], [9], [10], [11], [14], [15]. Interestingly, LISP offers a standard, inter-domain, and dynamic overlay that enables low-CAPEX innovation at the network layer [8].…”

Multihoming for Mobile Internet of Multimedia Things

“…As part of our previous work we have implemented a simulated demonstrator based on Cisco devices supporting LISP [47] in order to demonstrate the benefits of LISP compared to other routing protocols but also to validate security and load-balancing solutions. The demonstrator, part of our previous work, was illustrative for the LISP configuration and functionality and can be applied for several scenarios, from distributed enterprise offices to the mobility use-cases, ensuring encrypted communications, failover mechanisms, and load-balancing in an emulated enterprise environment.…”
