Gigabit networking research at Bellcore

Abstract

The AURORA gigabit network is a cooperative testbed connecting Philadelphia, Morristown, Yorktown Heights, and Cambridge. m m m m m m m m m m m

Compact grid layouts of multi-level networks

“…Thus, the layout area of the network is determined by the layout area of the permutations that are routed in Steps (2) and (4). Since these unshut& and shuffle permutations can be implemented in N/2+0(N) columns, we get the following result if we use AKS in Steps (I), (3), and (5).…”

“…Many ATM switches use the butterfly network and its related networks and sorters in order to route connections; see [30] for an overview, and [6] for generic ATM switch systems with such networks. Such ATM switches have been designed OI developed at Bellcore (named Sunshine [4]), AT&T Bell Labs (named Starlite [13]), Lucent Technologies [16], Telecorn Australia Research Labs [23], and elsewhere (for example, Starburst [31]). For high speed and performance, these ATM switches are fabricated as VLSI chips, with layouts based on Batcher's sorters, Benes networks, or banyan networks.…”

The transport layer

“…It is intended for a heterogeneous internetwork with a large bandwidth-delay product [Biersack et al 1992;Feldmeier 1993b]. It uses backpressure for flow and congestion control, and is designed to carry three major application classes: constrained latency service, transactions, and bulk data transfer.…”

Kommunikation

“…SNR unterstützt Implementierungen auf parallelen Architekturen durch die Aufteilung des Protokolls in endliche Automaten mit unterschiedlichen Aufgaben. TP++ ist ein universelles Transportprotokoll, das sich derzeit bei Bellcore(Bell Communications Research) in Morristown in Entwicklung befindet[BCFA92]. Das Protokoll soll für die Unterstützung von Multimedia-Anwendungen in leistungsfähigen Arbeitsplatzrechnern und für den Einsatz in heterogenen Gigabit-Netzen mit hoher Pfadkapazität geeignet sein.…”
