Information Elements for device location in IPFIX
IETF Internet-DraftInternational audienceThis document defines a set of Information Elements for IP Flow Information Export (IPFIX) protocol to represent location information of any device (mobile or not) acting as an IPFIX flow exporter. The specified Information Elements support geodetic and civic location data
Extending IP Flow-Based Network Monitoring with Location Information
Internet Draft - IETFIP Flow-based monitoring lacks a mechanism to associate measured IP Flow information with the geographic location of the device where theIP Flows have been observed. This document defines a set of guidelines and best practices to extend IP Flow monitoring protocols with location information of the device (both fixed and mobile) that acts as an IP Flow metering process

Integration of unidirectional technologies into wireless back-haul architecture
This thesis was submitted for the degree of Docter of Philosophy and awarded by Brunel University.Back-haul infrastructures of today's wireless operators must support the triple-play services demanded by the market or regulatory bodies. To cope with increasing capacity demand, the EU FP7 project CARMEN has developed a cost-effective heterogeneous
multi-radio wireless back-haul architecture, which may also leverage the native multicast
capabilities of broadcast technologies such as DVB-T to off-load high-bandwidth broadcast
content delivery. However, the integration of such unidirectional technologies into a packet-switched architecture requires careful considerations. The contribution of this thesis is the investigation, design and evaluation of protocols and mechanisms facilitating the integration of such unidirectional technologies into the wireless
back-haul architecture so that they can be configured and utilized by the spectrum and
capacity optimization modules. This integration mainly concerns the control plane and, in particular, the aspects related to resource and capability descriptions, neighborhood, link and Multi Protocol Label Switching (MPLS) Label-Switched Path (LSP) monitoring, unicast and multicast LSP signalling as well as topology forming and maintenance. During the course of this study we have analyzed the problem space, proposed solutions to the resulting research questions and evaluated our approach. Our results show that the now Unidirectional Technology (UDT)-aware architecture can readily consider
Unidirectional Technologies (UDTs) to distribute, for example, broadcast content
