multicast capacity of packet switched ring wdm networks
IEEE Transactions on Information Theory, 2008Co-Authors: Michael Scheutzow, Martin Reisslein, Martin Maier, Patrick SeelingAbstract:Packet-switched unidirectional and bidirectional ring wavelength division multiplexing (WDM) networks with destination stripping provide an increased capacity due to spatial wavelength reuse. Besides unicast Traffic, future destination stripping ring WDM networks also need to support multicast Traffic efficiently. This article examines the largest achievable transmitter throughput, receiver throughput, and multicast throughput of both unidirectional and bidirectional ring WDM networks with destination stripping. A probabilistic analysis evaluates both the nominal capacity, which is based on the mean hop distances traveled by the multicast packet copies, and the effective capacity, which is based on the ring segment with the highest utilization probability, for each of the three throughput metrics. The developed analytical methodology accommodates not only multicast Traffic with arbitrary multicast fanout but also unicast and Broadcast Traffic. Numerical investigations compare the nominal transmission, receiver, and multicast capacities with the effective transmission, receiver, and multicast capacities and examine the impact of number of ring nodes and multicast fanout on the effective transmission, reception, and multicast capacity of both types of ring networks for different unicast, multicast, and Broadcast Traffic scenarios and different mixes of unicast and multicast Traffic. The presented analytical methodology enables the evaluation and comparison of future multicast-capable medium access control (MAC) protocols for unidirectional and bidirectional ring WDM networks in terms of transmitter, receiver, and multicast throughput efficiency.

medium access control in wireless network on chip a context analysis
arXiv: Distributed Parallel and Cluster Computing, 2018Co-Authors: Sergi Abadal, Albert Mestres, Eduard Alarcon, Josep Torrellas, Albert CabellosaparicioAbstract:Wireless on-chip communication is a promising candidate to address the performance and efficiency issues that arise when scaling current Network-on-Chip (NoC) techniques to manycore processors. A Wireless Network-on-Chip (WNoC) can serve global and Broadcast Traffic with ultra-low latency even in thousand-core chips, thus acting as a natural complement of conventional and throughput-oriented wireline NoCs. However, the development of Medium Access Control (MAC) strategies needed to efficiently share the wireless medium among the increasing number of cores remains as a considerable challenge given the singularities of the environment and the novelty of the research area. In this position paper, we present a context analysis describing the physical constraints, performance objectives, and Traffic characteristics of the on-chip communication paradigm. We summarize the main differences with respect to traditional wireless scenarios, to then discuss their implications on the design of MAC protocols for manycore WNoCs, with the ultimate goal of kickstarting this arguably unexplored research area.

scalability of Broadcast performance in wireless network on chip
IEEE Transactions on Parallel and Distributed Systems, 2016Co-Authors: Sergi Abadal, Albert Mestres, Mario Nemirovsky, Heekwan Lee, Antonio Gonzalez, Eduard Alarcon, Albert CabellosaparicioAbstract:Networks-on-Chip (NoCs) are currently the paradigm of choice to interconnect the cores of a chip multiprocessor. However, conventional NoCs may not suffice to fulfill the on-chip communication requirements of processors with hundreds or thousands of cores. The main reason is that the performance of such networks drops as the number of cores grows, especially in the presence of multicast and Broadcast Traffic. This not only limits the scalability of current multiprocessor architectures, but also sets a performance wall that prevents the development of architectures that generate moderate-to-high levels of multicast. In this paper, a Wireless Network-on-Chip (WNoC) where all cores share a single broadband channel is presented. Such design is conceived to provide low latency and ordered delivery for multicast/Broadcast Traffic, in an attempt to complement a wireline NoC that will transport the rest of communication flows. To assess the feasibility of this approach, the network performance of WNoC is analyzed as a function of the system size and the channel capacity, and then compared to that of wireline NoCs with embedded multicast support. Based on this evaluation, preliminary results on the potential performance of the proposed hybrid scheme are provided, together with guidelines for the design of MAC protocols for WNoC.

a mac protocol for reliable Broadcast communications in wireless network on chip
Network on Chip Architectures, 2016Co-Authors: Albert Mestres, Sergi Abadal, Eduard Alarcon, Josep Torrellas, Albert CabellosaparicioAbstract:The Wireless Network-on-Chip (WNoC) paradigm holds considerable promise for the implementation of fast and efficient on-chip networks in manycore chips. Among other advantages, wireless communications provide natural Broadcast support, a highly desirable feature in manycore architectures yet difficult to achieve with current interconnects. As technology advancements allow the integration of more wireless interfaces within the same chip, a critical aspect is how to efficiently share the wireless medium while reliably carrying Broadcast Traffic. This paper introduces the {Broadcast, Reliability, Sensing} protocol (BRS-MAC), which exploits the particularities of the WNoC context to meet its stringent requirements. BRS-MAC is flexible and employs a collision detection and notification scheme that scales with the number of receivers, making it compatible with Broadcast communications. The proposed protocol is modeled and evaluated, showing a clear latency advantage with respect to wired on-chip networks and WNoCs with token passing.
