A large fraction of today's Internet applications are internally publish/subscribe in nature; the current architecture makes it cumbersome and inept to support them. In essence, supporting efficient publish/subscribe requires data-oriented naming, efficient multicast, and in-network caching. Deployment of native IP-based multicast has failed, and(More)
Many network solutions and overlay networks utilize probabilistic techniques to reduce information processing and networking costs. This survey article presents a number of frequently used and useful probabilistic techniques. Bloom filters and their variants are of prime importance, and they are heavily used in various distributed systems. This has been(More)
Prior work on centralized Routing Control Platform (RCP) has shown many benefits in flexible routing, enhanced security, and ISP connectivity management tasks. In this paper, we discuss RCPs in the context of OpenFlow/SDN, describing potential use cases and identifying deployment challenges and advantages. We propose a controller-centric hybrid networking(More)
Several recently proposed multicast protocols use inpacket Bloom filters to encode multicast trees. These mechanisms are in principle highly scalable because no per-flow state is required in the routers and because routing decisions can be made efficiently by simply checking for the presence of outbound links in the filter. Yet, the viability of previous(More)
In this paper, we propose and analyze an in-packet Bloom-filter-based source-routing architecture resistant to Distributed Denial-of-Service attacks. The approach is based on forwarding identifiers that act simultaneously as path designators, i.e. define which path the packet should take, and as capabilities, i.e. effectively allowing the forwarding nodes(More)
The networking equipment market is being transformed by the need for greater openness and flexibility, not only for research purposes but also for in-house innovation by the equipment owners. In contrast to networking gear following the model of computer mainframes, where closed software runs on proprietary hardware, the software-defined networking approach(More)
The Internet has led to the creation of a digital society, where (almost) everything is connected and is accessible from anywhere. However, despite their widespread adoption, traditional IP networks are complex and very hard to manage. It is both difficult to configure the network according to predefined policies, and to reconfigure it to respond to faults,(More)
As the density of wireless networks continues to grow with more clients, more base stations, and more traffic, designing cost-effective wireless solutions with efficient resource usage and ease to manage is an increasing challenging task due to the overall system complexity. A number of vendors offer scalable and high-performance wireless networks but at a(More)
In response to the limitations of the Internet architecture when used for applications for which it was not originally designed, a series of <i>clean slate</i> efforts have emerged to shape the so-called <i>future Internet</i>. Recently, visionary voices have advised a shift in the networking problem under research, moving from seamless host-reachability to(More)
Recent proposals on Data Center Networks (DCN) are based on centralized control and a logical network fabric following a well-controlled baseline topology. The architectural split of control and data planes and the new control plane abstractions have been touted as Software-Defined Networking (SDN), where the OpenFlow protocol is one common choice for the(More)
