The current Big Data scenario is mainly characterized by the huge amount of data available on the Internet. Some deployed mechanisms for handling such raw data rely on Data Centres (DCs) based on massive storage, memory and processing capacity, in which solutions like BigTable, MapReduce and Dynamo process information in order to provide its retrieval. The HCube presents a DC alternative for data...
The information society is facing a sharp increase in the amount of information driven by the plethora of new applications that sprouts all the time. The amount of data now circulating on the Internet is over zettabytes (ZB), resulting in a scenario defined in the literature as Big Data. In order to handle such challenging scenario, the deployed solutions rely not only on massive storage, memory and...
In this paper we present a performance analysis of XOR-based flat routing protocols in high mobility conditions, considering a vehicular ad hoc network (VANET) formed in a highway scenario. First, we describe an XOR-based protocol that incorporates several adaptations of the existing XOR-based routing algorithms for wired networks, in order to cope with the network mobility. Then we propose an improved...
A frequent subject in forums, academia and industry is the evolution of the Internet in terms of routing. Basically, the scalability in the Default Free Zone related to (1) the growing rate of the routing tables and (2) the convergence of the routing system, are pointed by routing experts as the main concerns of the current mechanism. Several approaches have emerged, but they normally require a mapping...
Flat routing is subject of many proposals found in the literature. One challenging task in this scenario is the flat identity space management since aggregation is not possible. The Landmark-based Flat Routing (LFR) proposal is an alternative to address the routing tables' growth in a scenario which (1) organizes the network in regions represented by landmarks and (2) adopts an XOR-based routing mechanism...
In this paper we make the domain entity a first class citizen. The concept of Domain Identifiers (DIDs) is introduced to effectively bring the domains to the next generation Internet scenario. The paper presents an architecture to address challenging next generation Internet requirements such as node and domain mobility, multi-homing, security, network composition and inter-domain routing. Although...
The current internetworking architecture presents some limitations to naturally support mobility, security and multi- homing. Among the limitations, the IP semantic overload seems to be a primary issue to be considered. In this paper we present a next generation internetworking architecture to overcome the IP semantic overload by introducing an identity layer located between the network and transport...
