Concurrent Communication Among Multi-Transceiver Stations over Shared Media
Abstract
To increase a network's throughput beyond a single bus's data rate without using dedicated switching nodes, multiple buses and multi-transceiver stations are required. The design space of single-hop interconnections are explored among such stations; i.e., interconnections that provide a passive transmission path between any two stations. For example, interconnections whose throughput can grow quadratically with the number of transmitters and receivers per station. They consist of a collection of buses, each of which interconnects only a proper subset of the stations using one of their transceivers. Yet, for any two stations, there is at least one bus to which they are both connected. We refer to these as selected-broadcast interconnections, or SBI's. The use of unidirectional media significantly enriches the design space of SBI's since, unlike with bidirectional media, the sets of receivers that hear two transmissions need not be identical or disjoint. Implementation-related issues, such as power budget in fiber optic implementations, are discussed in the context of local-area networks. Lastly, the concept of SBI's is shown to also apply to memory-processor interconnection, as well as to additional domains. A spread-spectrum channel can accommodate several concurrent successful transmissions, and a single-transceiver node can thus utilize only a small fraction of the channel's capacity. To allocate the appropriate fraction of capacity to a busy node, equip it with several transmitters and receivers, thereby turning it into a super-node.
