Dynamic Bandwidth Allocation for Ethernet Passive Optical Networks
With the explosive growth of the Internet and ever-increasing users’ demand for various broadband applications, such as Internet telephony, high-definition television (HDTV), interactive games, and video on demand, subscriber access networks, which cover the “last mile” area, and serve numerous residential and small business users, have become a bandwidth bottleneck in providing broadband servi...
متن کاملEnhanced Dynamic Bandwidth Allocation Algorithm in Ethernet Passive Optical Networks
Byungjoo Park et al. 301 As broadband access is evolving from digital subscriber lines to optical access networks, Ethernet passive optical networks (EPONs) are considered a promising solution for next generation broadband access. The point-tomultipoint topology of EPONs requires a time-division multiple access MAC protocol for upstream transmission. In this paper, we propose a new enhanced dyn...
متن کاملAdaptive dynamic bandwidth allocation algorithm with sorting report messages for ethernet passive optical network
Broadband access networks using passive optical network (PON) technology can extend the transmission distance and increase the transmission capacity of carrier networks. One PON solution, the Ethernet passive optical network (EPON), can provide huge bandwidth capacity, low cost, simple architecture and easy maintenance. Therefore EPON becomes a promising candidate for future last-mile solutions...
متن کاملRecent Dynamic Bandwidth Allocation Algorithm Methods in Ethernet Passive Optical Network
The “last mile” bandwidth bottleneck problem can be best solved by using Ethernet Passive Optical Network (EPON). EPON is a promising technology to implement the Fiber To The Home solution. Dynamic bandwidth allocation (DBA) is one of the critical issues in the design of the EPON system that has been studied by many researches. This paper introduces the fundamental concepts on EPONs, its protoc...
متن کاملRequest-based Dynamic Bandwidth Allocation of Gigabit Passive Optical Network
We propose request-based dynamic bandwidth allocation (DBA) of gigabit passive optical network (GPON). The optical line terminal (OLT) in GPON grants bandwidth to optical network units (ONUs). ONUs report request bandwidth which depends on queue lengths of traffic containers (TCONTs) to the OLT. In the OLT, DBA of GPON supports a request-based polling order to allocate bandwidth. Our request-ba...
