摘要： A solution for allowing conditional access to IP-based broadcast services in a passive optical network is disclosed. When a subscriber requests broadcast services by selecting a broadcast channel, an IP set-top converts the request into an IGMP join message and forwards the message to an ONU/ONT, a unit on the subscriber's side. The ONU/ONT delivers the message to an OLT interworking with a router while storing mapping information of the port that received the message and a MAC address of the selected channel. Thereafter, the OLT extracts information on MAC address of the IP set-top box and the requested broadcast data. The OLT compares the extracted information to the subscriber's subscription information and determines whether to provide the requested broadcast services. If the broadcast services may be provided, the broadcast data provided from the broadcast server is transmitted to the IP set-top box via ONU/ONT based on the stored mapping information.

摘要： Disclosed is a method and apparatus for controlling downstream traffic in an EPON (Ethernet Passive Optical Network). Individual tokens respectively for ONUs (Optical Network Units) are generated and stored, and a common token based on a total transfer rate of the EPON is generated and stored. In order to transmit downstream data, it is determined whether the downstream data is transmittable first by the corresponding individual token, and then second by the common token if the first determination is negative. In the case where traffic is concentrated on an ONU at a time, even if downstream data cannot be transmitted by an individual token for the corresponding ONU, the common token not used by other ONUs can be used to transmit the downstream data. It is thus possible to guarantee minimum/maximum transfer rates to all ONUs and ensure QoS against burst traffic in the EPON.

摘要： In a gigabit-capable passive optical network (GPON) and a method for bandwidth allocation in the GPON system, when an optical network unit (ONU) requests a bandwidth less than its preset minimum bandwidth, the requested bandwidth is allocated to the ONU. When there are traffic-container (T-CONT) classes of ONUs not allocated bandwidth after the requested bandwidth allocation, a spare bandwidth after the requested bandwidth allocation is dynamically allocated to the T-CONT class of each ONU according to a weight of each T-CONT class and a percentage of each T-CONT buffer queue. Thus, in the short term, upstream channel transmission according to T-CONT priority in a congested state can be ensured, and, in the long run, network traffic congestion can be prevented.

摘要： In a gigabit-capable passive optical network (GPON) system and in a method for bandwidth allocation in a passive optical network (PON) system, a minimum bandwidth is allocated to optical network units (ONUs) for minimal transmission assurance dependent on a traffic characteristic of each ONU, and when there is a traffic-container (T-CONT) class of an ONU not allocated bandwidth after minimum bandwidth allocation to all ONUs, an extra bandwidth remaining after minimum bandwidth allocation is dynamically allocated to each T-CONT class according to a weight of the T-CONT class. Thus, efficient bandwidth allocation, considering fairness between ONUs and priority of each T-CONT, is realized.

摘要： A method for upstream traffic control in an Ethernet-based passive optical network, adapted for preventing a penalty phenomenon occurring in making upstream data transfer on basis of High Priority First Allocation (HPFA) algorithm. The method includes the steps of determining whether are any data frames to transfer in the first buffer; if it is determined that there are any data frames to transfer in the first buffer, determining whether the data frame does not exceed a low water mark indicative of a reference value set up to ensure the minimum transfer traffic; if it is determined that the data frame in the first buffer does not exceed the low water mark, then transferring the data frame stored in the first buffer and determining whether the data frame in a second buffer does not exceed the low water mark; if it is determined that the data frame in the second buffer does not exceed the low water mark, then determining whether the data frame to transfer in a third buffer does not exceed the low water mark; if it is determined that the data frame to transfer in the third buffer does not exceed the low water mark, then transferring the respective data frame stored in the second and third buffers.
