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...
This paper discusses a novel data center architecture based on load-balanced forwarding with in-packet Bloom filters enabled by two support services that distribute the directory and topology state of OpenFlow controller applications. By deploying an army of Rack Managers acting as OpenFlow controllers, the proposed architecture promises scalability, performance and fault-tolerance. We conjecture...
Many software vendors are providing mechanisms for parallel content retrieval using multiple connections, e.g., parallel HTTP channels, to increase the availability and reliability of the download procedure. At the same time, there is no native verification mechanism to support simultaneous content verification from multiple sources. While it is possible to set-up multiple TLS tunnels with different...
The increasing volume of semantic content available in the Web, generally classified by concept hierarchies or simple ontologies, turns the searching and reasoning upon these data a great challenge. Generally, a search in Semantic Web may not be addressed to a specific document, but to a group of data classified in the same concept. Several structures used to distribute data, e.g. P2P networks, use...
Current security protocols such as IPSec and TLS/SSL provide security mechanisms to authenticate and protect the communication between end-hosts over the Internet. Nonetheless, new communication scenarios like mobility and heterogeneous networks have exposed some technical limitations of these protocols. Both protocols employ the IP address as end-host identifier to establish security associations...
We introduce the Deletable Bloom filter (DlBF) as a new spin on the popular data structure based on compactly encoding the information of where collisions happen when inserting elements. The DlBF design enables false-negative-free deletions at a fraction of the cost in memory consumption, which turns to be appealing for certain probabilistic filter applications.
