Passive Optical Network (PON) system with characters of low-cost and high-efficiency has become a promising solution for access network in relieving the bandwidth bottleneck problem. PON system can provide high-speed optical subscriber networks with broad bandwidth and long distance transmission. In current telecommunication carriers' PON system, different service has its given priority which is configured by carriers based on common requirements. However, different users have their own requirement and inflexibility of the given default service priority causes users' inconvenience and frustration. In this paper, we propose a novel method of user controlled Port-IDentifier (Port-ID) assignment in a Gigabit-capable PON (GPON) system. This method provides users a more individualized priority determination mechanism for end users through assigning a multi-level Port-ID to different service. Then users can manage their own bandwidth based on their requirements for different service and carriers can provide a flexible service management mechanism.
Passive optical networks (PON) is being considered as a promising solution for next generation broadband access
network due to the convergence of broad bandwidth and low-cost fiber infrastructure along with its ability to
successfully support IP-based multimedia applications. PON system has its individual bandwidth allocation mechanism
compared with core network allocating bandwidth based on service priority level. However, no uniform bandwidth
allocation mechanism from access network to care network. In this paper we propose a novel method of extended
bandwidth allocation mechanism among multi-PON systems; then extended dynamic bandwidth allocation (DBA)
algorithm in a Gigabit-capable PON (GPON) system for core network is presented. The bandwidth management
mechanism among multi-optical line terminals (OLTs) can provide an end-to-end bandwidth guarantee for data
transmission. We conduct detailed simulation experiments to study the performance and validate the effectiveness of the
proposed method.
Ethernet Passive Optical Network (EPON) is an emerging access network technology that provides high bandwidth and cost-effective access lines between a carrier's central office (CO) and a customer site. But limited bandwidth is still a problem in EPON system. In this paper, we propose a new architecture for EPON system with storage function. Storage is embedded in optical network unit (ONU) to store data especially video data by checking the Logical Link Identifier (LLID). Subscribers can retrieve the data directly from the storage by sending requests to ONUs.
