New DNS64 performance measurement tool

DNS64 and NAT64 are IPv6 transition technologies enabling IPv6 only clients to communicate with IPv4 only servers. Our performance measurement tool, dns64perf++, is the word’s first standard DNS64 benchmarking tool that complies with the relevant Internet Draft. Its design and implementation is documented in our new position paper: G. Lencse, D. Bakai, “Design and implementation of a test program for benchmarking DNS64 servers”, IEICE Transactions on Communications, vol. E100-B, no. 6. pp. 948-954, Jun. 2017. DOI: 10.1587/transcom.2016EBN0007

Poster demonstration at “COST Intelligent Transport Systems: a Tool or a Toy?” Conference

Efficient traffic control and management is a fundamental and urgent challenge in our ever-growing cities. Evolving traffic light controller systems are playing an important role in these architectures by adaptively and dynamically coordinating individual traffic lights to achieve city-wide objectives of traffic operations. The integration of such systems with vehicle-to-anything (V2X) communication techniques could easily be the next step of this evolution. In this poster proposal a proof-of-concept implementation of V2X-integrated traffic light controller systems is presented.

New journal paper published about the MPT network layer multipath library in Computer Communications (Elsevier)

Multipath communication is aimed to utilize the multiple network interfaces of our contemporary IT devices for throughput aggregation and/or resilient communication. Unlike the more well-known MPTCP, the MPT multipath communication library operates at network level and builds on GRE in UDP encapsulation. For more information, please see our paper: B. Almási, G. Lencse, Sz. Szilágyi, “Investigating the Multipath Extension of the GRE in UDP Technology”, Computer Communications (Elsevier), vol. 103, no. 1, pp. 29-38, May 1, 2017, DOI: 10.1016/j.comcom.2017.02.002

New journal paper about the performance estimation of the mtd64-ng DNS64 implementation

DNS64 and NAT64 are IPv6 transition technologies enabling IPv6 only clients to communicate with IPv4 only servers. Mtd64-ng is a novel DNS64 implementation, being a successor of MTD64. In this paper, the performance of mtd64-ng is compared with that of MTD64 and BIND. It is found that under heavy load conditions mtd64-ng can answer six times as many “AAAA” record requests per second than BIND. Mtd64-ng fixed two issues of MTD64 and also outperformed its predecessor by answering 46% more “AAAA” record requests per second under heavy load conditions. For further details, please refer to our paper: Gábor Lencse, “Performance Estimation of the Mtd64-ng DNS64 Implementation”, International Journal of Advances in Telecommunications, Electrotechnics, Signals and Systems, vol. 5, no 3, pp. 160-165, DOI: 10.11601/ijates.v5i3.176

AppLink Mobility Opportunity Budapest Conference and Startup Competition

MEDIANETS Lab was the co-organizer of the AppLink Mobility Opportunity Budapest Conference and Startup Competition, which hosted Scott Lyons (Head of Business & Partner Development, Connected Services, Ford) and Andreas Brockers (Smart Mobility team) together with other experts of the industry, international investors and business developers. We also had case studies from AdasWorks, Commsignia, and RECAR, roundtable discussion of experts about the future of mobility (dr. Vilmos Simon, the head of our lab participating in one of the roundtables), pre-arranged B2B meetings with investors and business developers.
