Research on prediction weighted interpolated polling dynamic bandwidth allocation for optical fiber bus based on gigabit passive optical network

Abstract

. Optical fiber bus technology is an important research direction in communication systems of electronic devices in special vehicle platforms. According to the requirements for communication quality between devices in special vehicle platforms, an optical fiber bus based on gigabit passive optical network topology is proposed. A data cache-based predictive weighted interpolated polling dynamic bandwidth allocation method is presented and investigated for the optical fiber bus’s upstream bandwidth allocation. The network controller establishes a weighted buffer area for the communication requirements in the polling period according to the type and data volume of the network terminal (NT) data stream and dynamically allocates the bandwidth of each optical NT to better meet the communication requirements for different data within the special device platform. Verification is done by means of OPNET software simulation and the establishment of a NT simulation test system in the laboratory. This proves that the proposed dynamic bandwidth allocation algorithm can reduce the end-to-end delay of RS422 port data by more than 50% and meet the Ethernet and controller area network port data delay requirements.

The MAC aware routing algorithm in elastic optical networks

“…In addition, the traditional optical network design and configure is in a static way. However, in next generation optical network, the burst of data traffic is dynamic and is easy to cause local link congestion which puts forward new requirements for dynamic adjustment of routing [1][2][3][4][5] . Therefore, this paper designs the medium access control (MAC) layer aware routing scheme in the network layer of node.…”

Optical Wireless Fronthaul-Enhanced High-Throughput FC-AE-1553 Space Networks

“…Another study [7] introduced a passive optical network FC-AE-1553 architecture and compared it with star topology and ring topology, revealing lower latency in PON FC-AE-1553. In addition to optimizing the FC-AE-1553 network architecture, several studies [8][9][10][11][12][13] have researched dynamic bandwidth allocation strategies based on factors such as traffic type, credit, or quality of service (QoS). While these studies have contributed to improving network bandwidth and enhancing the quality of service to some extent, they have been constrained by the theoretical upper limit of the Fiber Channel network due to the limited physical channels available.…”

“…This research subsequently fostered the development of a range of products based on FC-AE-1553, including FC-AE-1553 chips [40][41][42], as well as software [19] and hardware [43,44] products, for embedded and desktop applications. FC-AE-1553 network scheduling technology is also one of the main research directions of FC-AE-1553, encompassing dynamic bandwidth allocation [9,10,13], credit mechanisms [11], task scheduling [12], and quality of service (QoS) [8] considerations.…”
