A Dynamic Bandwidth Allocation Algorithm in Epon Networks
With the rapid development of Internet technology, there have been many new services which require high bandwidth. EPON (Ethernet Passive Optical Network) has become one of the best technologies in the next generation broadband access network because of their high-bandwidth and low-cost. Dynamic bandwidth allocation (DBA) is one of the most critical issues in EPON network. In this paper, a new ...
متن کاملEfficient Dynamic Bandwidth Allocation for Epon
Ethernet Passive Optical Network (EPON) has emerged as the solution of choice for the access network. In EPON, the data transfer channel is shared among users in the upstream direction. Therefore, it requires an arbitration method to allow ONUs to share the upstream bandwidth. There are many research papers on bandwidth arbitration schemes. Most of the Dynamic Bandwidth Allocation (DBA) schemes...
متن کاملDynamic bandwidth allocation algorithms in EPON: a simulation study
In this paper we present a dynamic bandwidth allocation algorithm for EPON, which makes use of the Multipoint Control Protocol (MPCP) with threshold reporting and with interand intra-ONU priority scheduling. Three varieties of this algorithm are compared, by means of a detailed simulation program, regarding average packet delay for several priorities, delay variation for constant bit rate (CBR)...
متن کاملExtra Window Scheme for Dynamic Bandwidth Allocation in EPON
To ensure efficient data transmission for multimedia services in Ethernet passive optical networks (EPON) which are considered as a promising solution to the last-mile problem in the broadband access network, they employ the media access control (MAC) mechanism by sharing efficiently the bandwidth of all optical network units (ONUs) and by avoiding data collisions in the upstream channel. The r...
متن کاملQoS ASSURED DYNAMIC BANDWIDTH ALLOCATION IN EPON-LTE NETWORKS
Ensuring stringent Quality of Service (QoS) requirements is a critical issue in determining the performance of the network. Added to that, when the network happen to be converged Ethernet Passive Optical Network (EPON) and Long Term Evolution (LTE) which is essential for today’s bandwidth-intensive customer needs, it is still more critical. Hence, allocation of resources to the end-points is th...
