“…Hossen et al [6,7] have proposed a new DBA algorithm for the multi-OLT PON-based hybrid networks. However, those papers have considered a network structure where a single uplink wavelength is used and every ONU is connected to a single service provider.…”

“…As all the OLTs use same polling table for RTT information, in the proposed scheme, it is called shared polling table. The shared polling table is also used to provide synchronization among the multiple OLTs [6]. The proposed MM-OAN architecture is considered to be deployed in the city area, i.e.…”

“…In the figure, for simplicity, only two service providers connected to every ONU, two OLTs, and a shared polling table are considered. The scheduling of the control messages follows the modified interleaved polling algorithm for the multi-OLT PON [6]. Here, both the OLTs are acknowledged about the RTT of each ONU from the shared polling table.…”

“…In the multi-OLT PON-based hybrid networks, proposed by Hossen et al [6,7], each ONU connects to the users of a single service provider that means no need to share a single ONU by the multiple service providers. However, in the PON-based OAN each ONU should be shared by all the service providers.…”

“…In the recent years, the optical access networks dominate the backbone access network space. A passive optical network (PON) uses point-to-multipoint (P2MP) fiber to the premises technology in which a passive optical splitter is used to enable a single optical fiber to serve multiple subscribers premises [1][2]. The PON effectively reduces the requirement of fiber deployment and transceivers at the optical line terminal (OLT) compared to the point-to-point (P2P) optical network architectures.…”

Modified Early DBA Algorithm for Reducing Packet Delay and Waiting Time of Unstable ONUs in PON

Passive optical network (PON) is a highly dynamic access network that effectively converge several service providers. In a time cycle, some optical network units (ONUs) of PON may miss the usual polling instant called unstable ONUs. According to the existing early dynamic bandwidth allocation (E-DBA) algorithm, once an ONU miss the usual polling instant it needs to be waited until the end of transmissions from the entire stable ONUs. So the unstable ONUs suffers from more waiting time than the stable ONUs. This paper proposes a new DBA algorithm called modified E-DBA (ME-DBA) algorithm, for reduction of waiting times of the unstable ONUs. In the proposed algorithm, total ONUs are divided into several small groups. The data packets from all the stable ONUs of a group are transmitted 1 st and then the data packets from the unstable ONUs of that group are transmitted. We have analyzed and compared the performance of the proposed ME-DBA algorithm with the existing E-DBA algorithm in terms of the delay and waiting time of the unstable ONUs by simulations. The simulation results show that the proposed algorithm provides lower packet delay and waiting time for the unstable ONUs than that of the existing E-DBA algorithm.
