摘要： An apparatus for transmitting a FEC frame is provided. The apparatus includes: a selector determining whether to perform FEC encoding on data to be transmitted; a Reed-Solomon encoding assembler receiving the data on which FEC encoding is to be performed as determined by the selector, and dividing the data into k-byte message blocks (k is a positive integer) for output; a Reed-Solomon encoder receiving the message blocks and performing Reed-Solomon encoding on the message blocks; and an output controller receiving an input parity generated by the Reed-Solomon encoding, and outputting the message block and the parity sequentially or outputting the data on which FEC encoding is not to be performed as determined by the selector. In order to correct an error caused by a transmission medium using FEC in a Reed-Solomon code type, FEC encoding/decoding of a frame is performed. A total transmission delay time is not influenced when FEC is bypassed, a delay caused by a shortened codeword is minimized, and a FEC encoding/decoding delays for frames having different lengths are equalized.

摘要： A method of controlling a Forward Error Correction (FEC) operation including: configuring a FEC frame to be transmitted between an OLT and an ONU comprising a FEC frame identifier indicating whether FEC should be performed, data, a first flag indicating that FEC should be performed, and a second flag indicating that the FEC frame is to be FEC encoded; initializing the OLT by disabling a FEC function; determining whether the ONU requires FEC to be performed based on a FEC frame identifier received from the ONU; IPG stretching the FEC frame when the ONU requires to FEC to be performed; and transmitting the FEC frame to the ONU after FEC encoding based on the second flag of an input frame to a PCS sublayer from an upper layer. The method controls an effective operation of a FEC of an ONU and an OLT without changing a Round Trip Time (RTT) according to optical link quality in an EPON. Accordingly, FEC is used only if necessary, thereby simplifying the managing of a link, and preventing an excessive 35% reduction of throughput caused by use of unnecessary FEC.
摘要翻译：一种控制前向纠错（FEC）操作的方法，包括：配置要在OLT和ONU之间传输的FEC帧，包括指示是否应执行FEC的FEC帧标识符，数据，指示应执行FEC的第一标志以及指示FEC帧要被FEC编码的第二标志; 通过禁用FEC功能来初始化OLT; 基于从ONU接收到的FEC帧标识来确定ONU是否需要执行FEC; 当ONU需要执行FEC时，IPG扩展FEC帧; 并且基于来自上层的PCS子层的基于输入帧的第二标志的FEC编码之后将FEC帧发送到ONU。该方法根据EPON中的光链路质量来控制ONU和OLT的FEC的有效操作，而不改变往返时间（RTT）。因此，仅在必要时使用FEC，从而简化链路的管理，并且防止由于使用不必要的FEC导致的吞吐量的过度的35％的降低。

摘要： A system and method is disclosed for determining performance bonds related to fixed payoff products, i.e. contracts which payoff a fixed amount based on the outcome of an underlying event regardless of the particular value of the underlying event. The worst outcome of the overall portfolio, which may contain more than one instrument, is calculated. This permits the portfolio to have both long and short positions on the same underlying event and offsets, e.g. long (bought but not closed out) and short (sold but not closed out) positions, among instruments in the portfolio are factored in. A universe of outcomes is constructed including single events with single outcomes, and the probability thereof, an single events with multiple outcomes, each with a probability thereof. This universe is implemented in a matrix probabilities on different outcomes, also referred to as “strikes.” Each strike/outcome then has an associated price and probability, typically factored together as single value reflective of both. Events with low probability will have low values, resulting in a lower margin requirement, as will be explained below. The margin requirement/performance bond is then set equal to the amount of the maximum loss that the portfolio can sustain for any possible outcome of the underlying event, adjusted for the probability of the outcome.

摘要： The invention provides a method and apparatus for allocating a dynamic band width of an EPON and an EPON master apparatus using the same. The bandwidth allocation is cycle based where every predetermined cycle, static gates are generated for all ONUs and dynamic gates are generated according to the reports using the remaining grant resource. The method for allocating an upstream bandwidth to transmit data from the ONUs to an OLT is as follows. A total allocatable grant length is calculated for the given cycle. A requested amount of grant length needed to transmit upstream data in each ONU is set based on report values collected from the report frames from all ONUs in the EPON. Then, distribution is made sequentially and repeatedly in a cycle by taking a basic unit from the total grant length and adding it to the grant length of the ONUs until the total allocatable grant length becomes 0 or the grant length allocated to all ONUs satisfy the requested amount of the grant length set in all ONUs.
