Abstract

Frequency-Division Multiplexing offers the potential to support many concurrent transmissions on a single optical fiber. However, for multiuser packet communications with unpredictable user demands (e.g., in a local or metropolitan area network), the coordination and control of access to the FDM channels is difficult. One of the authors recently proposed using a simple Protection- Against-Collision (PAG) circuit to solve this media access problem and achieve full optical connectivity. The PAC system has the potential to interconnect a thousand ports transmitting at one gigabit per second. In this paper, we discuss performance aspects of the PAC Optical Packet Network. We analyze the delay-throughput performance of this network for uniform traffic patterns. Our results show that in geographically-distributed applications the maximum achievable throughput (normalized to the transmission rate) is typically between 0.4 and 0.5 per channel. For example, the maximum achievable throughput is between 400 and 500 Gbps for a 1000-channel system with a 1-Gbps transmission rate. In a centralized switch, the (normalized) maximum achievable throughput can approach 0.8 per channel. These values are higher than previously- published optical systems.
