“…Using measured ranging information, the central scheduler uses another dedicated control channel to inform network nodes of when and on which wavelength channels to transmit/receive their packets. The network node can remain asynchronous, avoiding expensive synchronization circuits [10].…”

In this article, we propose three multicast scheduling mechanisms, lookback queue access, lookback ratio access, and double check head access, for the employment in the single-star Wavelength Division Multiplexing optical network. Each of the proposed scheduling schemes consists of two phases and is executed in real time. In general, the first phase is to search for a candidate multicast packet that can be sent, without partition, to all of its intended recipients. If phase 1 fails, the second phase is then activated to partition a multicast packet into multiple transmissions in accordance with specific criteria of each individual mechanism. These algorithms are designed to mitigate the head-of-line blocking effect, while at the same time achieving excellent network throughput levels and delay performance via the partitioning procedure. Performance results reveal the distinct features of each mechanism under various scenarios. For a wider range of networking environments, we further propose an interconnected dual-star structure and enhanced multicast scheduling algorithms. These enhanced schemes aim to exploit the inter-data channels efficiently and utilize the wavelength reuse property of the intra-data channels properly. Performance results have demonstrated the merits of deploying the proposed multicast algorithms in such a dual-star structure.

“…Another protocol aspect that we do not consider in this paper is the specific structure of the signaling for a control channel. Several methods and their performance, in particular in terms of scalability with the number of nodes and of delay, have been presented in [SG00,CZA93,KFG92,BM95,DG99].…”

We describe an architecture for optical local area network (LAN) or metropolitan area network (MAN) access. The architecture allows for bandwidth sharing within a wavelength and is robust to both link and node failures. The architecture can be utilized with an arbitrary, link-redundant mesh network (node-redundancy is necessary only to handle all node failures), and assumes neither the use of a star topology nor the ability to embed such a topology within the physical mesh. Reservation of bandwidth is performed in a centralized fashion at a (replicated) head end node, simplifying the implementation of complex sharing policies relative to implementation on a distributed set of routers. Unlike a router, however, the head end does not take any action on individual packets and, in particular, does not buffer packets. The architecture thus avoids the difficulties of processing packets in the optical domain while allowing for packetized shared access of wavelengths. In this paper, we describe the route construction scheme and prove its ability to recover from single link and single node failures, outline a flexible medium access protocol and discuss the implications for implementing specific policies, and propose a simple implementation of the recovery protocol in terms of state machines for per-link devices.

Abstract-In this work scaling of an optical broadcastand-select network based on a passive star coupler is explored for avionics applications. Each client in the network is equipped with a transmitter unit and a multichannel receiver capable of receiving signals from all other clients connected to the star coupler. We propose a connecting node concept to scale the number of clients supported by the architecture. These connecting nodes act as bridges between star couplers, enabling the organization of several star couplers into a topology with additional clients. This design is modeled in the PhoenixSim simulation environment, and system-level simulation results are reported. We then propose the ring topology and dimension-N topology to interconnect and scale star couplers. Finally we compare the ring and dimension-N topologies in terms of scalability limit at different crossing traffic loads, revealing the trade-offs between latency, system complexity, and scalability. Our study shows that a robust, lowlatency network of up to hundreds of clients, sufficient for current and next-generation avionics applications, can be built using off-the-shelf and near-term commercial technology.
