An algorithm for scheduling hybrid slot-size to increase traffic density in EPONs

Abstract

The current basically Ethernet passive optical network (EPON) efficiently supports different service classes, i.e., Giant Prime concern (GP) traffic and Efficiently-best (EE) traffic, in future-generation networks. The difficult task is finding the efficient Dynamic Bandwidth Allocation (DBA) procedure task which suggests service classes of bandwidth simultaneously. This paper suggests improved version to DBA algorithm, Remodeled version-Hybrid division-size/Rate (HDSR) scheme. The modified control message scheduling algorithm is also discussed along with Remodeled-HDSR Algorithm which fits to the proposed scheme. In the modified Remodeled-HSSR scheme, time cycle length is identical classified accordingly with two subparts. In algorithm as explained in order to increase traffic density, the subdivision part of the planned cycle, the traffic conditions are dynamically suggested an improved version for Best effort traffic of multiple ONUs. In the First subdivision part of the span time analysis time will not be compressed, particularly at less buffer status conditions plan buffer status of the HP traffic. The Remodeled control message algorithm which predefined status and is scheduled particularly which controls connecting the sub-parts of the planned cycles of the sequence time and in-turn increases synchronization between two Gate messages to particular ONUs.
