A named data networking flexible framework for management communications

The ongoing changes in the way we use the Internet are motivating the definition of new information-distributing designs for an interworking layer. Recently, information-centric networking (ICN) concepts have defined mechanisms focusing on which information to get rather than where it is located. However, the still unfledged architectures instantiating such concepts have disregarded vital operations, such as management aspects aiming to optimize content retrieval by the User Equipment (UE). In this article, a flexible management framework is proposed, which enhances existing Named Data Networking (NDN) architectures in allowing both the network and the UE to employ management mechanisms over the NDN fabric. We illustrate our management framework with an implementation over an open-source NDN software, considering the specific case study of interface management. We quantitatively access the performance gains achieved through the usage of this framework in such scenarios, when compared to un-managed NDN mechanisms.This article has been partially supported by the Portuguese Foundation for Science and Technology (FCT) grant agreement SFRH / BD / 61629 / 2009, and by the Madrid Community through the MEDIANET project (S-2009/TIC- 1468).Publicad

Internames: a name-to-name principle for the future Internet

We propose Internames, an architectural framework in which names are used to identify all entities involved in communication: contents, users, devices, logical as well as physical points involved in the communication, and services. By not having a static binding between the name of a communication entity and its current location, we allow entities to be mobile, enable them to be reached by any of a number of basic communication primitives, enable communication to span networks with different technologies and allow for disconnected operation. Furthermore, with the ability to communicate between names, the communication path can be dynamically bound to any of a number of end-points, and the end-points themselves could change as needed. A key benefit of our architecture is its ability to accommodate gradual migration from the current IP infrastructure to a future that may be a ubiquitous Information Centric Network. Basic building blocks of Internames are: i) a name-based Application Programming Interface; ii) a separation of identifiers (names) and locators; iii) a powerful Name Resolution Service (NRS) that dynamically maps names to locators, as a function of time/location/context/service; iv) a built-in capacity of evolution, allowing a transparent migration from current networks and the ability to include as particular cases current specific architectures. To achieve this vision, shared by many other researchers, we exploit and expand on Information Centric Networking principles, extending ICN functionality beyond content retrieval, easing send-to-name and push services, and allowing to use names also to route data in the return path. A key role in this architecture is played by the NRS, which allows for the co-existence of multiple network "realms", including current IP and non-IP networks, glued together by a name-to-name overarching communication primitive.Comment: 6 page

iTETRIS Platform Architecture for the Integration of Cooperative Traffic and Wireless Simulations

The use of cooperative wireless communications can support driving through dynamic exchange of Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) messages. Traffic applications based on such systems will be able to generate a safer, faster, cheaper and cleaner way for people and goods to move. In this context, the iTERIS project aims at providing the framework to combine traffic mobility and wireless communication simulations for large scale testing of traffic management solutions based on cooperative systems. This paper addresses the description and explanation of the implementation choices taken to build a modular and interoperable architecture integrating heterogeneous traffic and wireless simulators, and application algorithms supporting traffic management strategies. The functions of an “in-between” control system for managing correct simulation executions over the platform are presented. The inter-block interaction procedures identified to ensure optimum data transfer for simulation efficiency are also introduced
