time driven priority Router Implementation analysis and experiments
IEEE Transactions on Computers, 2013Co-Authors: Mario Baldi, Guido MarchettoAbstract:Low complexity solutions to provide deterministic quality over packet switched networks while achieving high resource utilization have been an open research issue for many years. Service differentiation combined with resource overprovisioning has been considered an acceptable compromise and widely deployed given that the amount of traffic requiring quality guarantees has been limited. This approach is not viable, though, as new bandwidth hungry applications, such as video on demand, telepresence, and virtual reality, populate networks invalidating the rationale that made it acceptable so far. Time-driven priority represents a potentially interesting solution. However, the fact that the network operation is based on a time reference shared by all nodes raises concerns on the complexity of the nodes, from the point of view of both their hardware and software architecture. This work analyzes the implications that the timing requirements of time-driven priority have on network nodes and shows how proper operation can be ensured even when system components introduce timing uncertainties. Experimental results on a time-driven priority Router Implementation based on a personal computer both validate the analysis and demonstrate the feasibility of the technology even on an architecture that is not designed for operating under timing constraints.

time driven priority Router Implementation and first experiments
International Conference on Communications, 2006Co-Authors: Mario Baldi, Guido Marchetto, Fulvio Risso, G Galante, Riccardo Scopigno, Federico StiranoAbstract:This paper reports on the Implementation of Time-Driven Priority (TDP) scheduling on a FreeBSD platform. This work is part of a TDP prototyping and demonstration project aimed at showing the implications of TDP deployment in packet-switched networks, especially benefits for real-time applications. This paper focuses on practical aspects related to the Implementation of the technology on a Personal Computer (PC)-based Router and presents the experimental results obtained on a testbed network. The basic building blocks of a TDP Router are described and Implementation choices are discussed. The relevant results achieved and here presented can be categorized into two types: qualitative results, including the successful integration of all needed blocks and the insight obtained on the complexity related to the Implementation of a TDP Router, and quantitative ones, including measures of achievable network utilization and of jitter experienced on a fully-loaded TDP network. The outcome demonstrates the effectiveness of the presented Implementation while confirming TDP points of strength.

ocnoc efficient one cycle Router Implementation for 3d mesh network on chip
International Journal of Research, 2015Co-Authors: Pravallika L Kammila, Dukkipati Venkanna BabuAbstract:Multiprocessor system on chip which is a most developed architecture with different features. One of the most important is networking. Networking which required high speed for the traffic permutation in which each input sends traffic to each output by using pipelined circuit switching network which is better compared with other on-chip network. The pipelined circuit switching offers guarantee of permuted data with dynamic path setup scheme for selecting arbitrary schemes. Another most important aspect is Low Power Analysis which mainly reduced the leakage and optimists the dynamic power. key words - Pipelined circuit switching; traffic permutation; dynamic path setup scheme; arbitrary scheme; dynamic power consumption

the cross protect Router Implementation tests and opportunities
IEEE Communications Magazine, 2014Co-Authors: Jerzy Domzal, Jakub Dudek, Piotr Jurkiewicz, Lukasz Romanski, Robert WojcikAbstract:The concept of flow-aware networking (FAN) has been introduced, discussed, and analyzed only with the use of mathematical models or computer simulations. This article presents the results of FAN's first practical Implementation. For the environment, the Click Modular Router was chosen. In the article, vital Implementation-related issues are shown and analyzed. The results of post-Implementation tests are also presented. They confirm the advantages of the XP Router over the IP Router. We prove that traffic in FAN is served fairly, and the packets of streaming flows are transmitted with high priority. Moreover, the test results confirm that streaming flows are served with acceptable quality even in highly loaded links, which is not observed in the classic IP network. The tests also show several problems not caught by the simulative studies available in the literature. First of all, to increase efficiency, a flow list had to be implemented in a different way than originally proposed. Also, a queuing algorithm had to be altered to eliminate too frequent changes of flow states, which resulted in a lack of stability. The presented tests ultimately prove that FAN works as a concept and that, by reaching maturity, it is ready for largescale deployment.

resource public key infrastructure rpki Router Implementation report
RFC, 2014Co-Authors: Matthias Waehlisch, Randy Bush, Keyur Patel, Hannes Gredler, Rob AusteinAbstract:This document is an Implementation report for the Resource Public Key Infrastructure (RPKI) Router protocol as defined in RFC 6810. The authors did not verify the accuracy of the information provided by respondents. The respondents are experts with the Implementations they reported on, and their responses are considered authoritative for the Implementations for which their responses represent. The respondents were asked to only use the "YES" answer if the feature had at least been tested in the lab.
