Architecture and Analysis of Accelerative Pre-Allocation Protocol for WDM Star-Coupled Networks

Abstract

In this paper, a new media access control (MAC) protocol, the AP-WDMA (accelerative pre-allocation), is proposed for the WDMA. Through examples and evaluations, the AP-WDMA is demonstrated to be able to reduce the delay through the accelerative mechanism. The degree of delay reduction depends on the traffic load. Higher degree of locality will have higher delay reduction. The AP-WDMA relieves the technology constraints by reducing the tenability to only one end and the table size to only n+2 units of memory space, where n is the number of stations. In addition, it is suitable for wavelength-limited networks. Therefore, the proposed AP-WDMA is indeed a better WDMA protocol.
