Abstract: An authentication method for link protection between an OLT and an ONU newly connected thereto in an EPON, which is implemented in a data link layer to which cryptography is applied. First, an authentication key is distributed to both the OLT and an ONU. The OLT (or ONU) generates first and second random values, generates an authentication request frame containing the random values, and transmits it to the ONU (or OLT). The ONU generates a first hash value according to a hash function using the random values contained in the request frame, and transmits an authentication response frame containing the first hash value to the OLT. The OLT compares the first hash value with a second hash value calculated by it according to the has function using the two random values and an authentication key distributed to it, and transmits an authentication result frame to the ONU.

Abstract: Disclosed herein is an optical transmitter having an analog/digital mixed-mode temperature compensation function. The optical transmitter, when detecting the optical output power of a laser diode, which outputs logic levels “1” and “0” as optical signals, through a monitoring photodiode, and controlling the bias current of a laser drive circuit to maintain the logic levels “1” and “0” at constant values, includes programs for controlling the bias current and modulation current of the laser drive circuit based on an variation in temperature, and is configured such that a temperature compensation circuit includes a digital control unit for controlling the bias current and modulation current of the laser drive circuit using the programs, so that temperature compensation operation can be adjusted only by the modification of the programs of the distal control unit.

Abstract: A system and method for risk analysis of a portfolio of derivative products is disclosed which is conducted based on a set of flexible rules. The system and method allow creating predefined sets of products for the purpose of future risk offsets. If a futures trade as a subset of that set of products that met a threshold level, then the subset is assigned the offset value (or a pro rata or other portion of the offset value) of the predefined set. For example, assume that the predefined set consists of one S&P 500 futures, one NASDAQ futures, one S&P Midcap 400 futures and one Russell 1000 futures and the threshold is three. If the futures trader holds any three of those four futures, the three futures can be grouped, assigned an offset value, and this group can be used as one asset for purpose of further risk offsets.

Abstract: 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.

Abstract: A graphic user interface is disclosed that combines a traditional trading, bookkeeping system or clearing system window with a detailed margin and/or collateral asset calculation analysis window on a single screen. The disclosed GUI provides the flexibility to analyze any combination of products or instrument classes such as single stock futures, futures (of all types), options (of all types), forward contracts, security options, securities and cash-based assets. Conventional systems merely block entry of orders beyond a predetermined credit limit or display clearing/bookkeeping information on all types of portfolio or accounts.

Abstract: A system and method for using asymmetrical offsets for products in a risk management analysis system are disclosed. Conventional systems assign symmetrical offsets for products, that is, if two products have an 80% correlation they each would be assigned an offset of 80% with respect to each other. However, it is desirable to allow for asymmetrical offsets. In the disclosed system and method, when two products have a correlation of 80%, one may be assigned an offset of 75% and the other may be assigned an offset of 80%. There are many reasons to vary the offset between the products. The varying offset may reflect an asymmetry in the risk in one of the products, such as being traded in an illiquid market or in a less desirable venue. The varying offset may correct for an imbalance in spread credits due to special charges from intra spreading.

Abstract: A risk management system and method is disclosed which utilizes a flexible and configurable set of spreading techniques which may be incorporated into existing risk management software to enhance functionality, flexibility and accuracy. In the disclosed embodiments, multiple different types of spreading are combined to allow for a more accurate assessment of risk. In one exemplary embodiment, a subset of the derivative products held by a futures trader are first analyzed by the scanning based spreading methodology. Typically, futures products in the same class of products (e.g. equity futures or agricultural futures) would be analyzed together by the scanning based spreading methodology. Then an average delta would be calculated for that subset. Using that delta, that subset would then be analyzed in relation to the remaining derivative products(not in the subset) using a delta based spreading methodology.

Abstract: A system and method for analyzing correlation between the assets given by the trader for collateral and that trader's open positions is disclosed. Thus, if the collateral is correlated to the trader's open positions, then some offset can be given. If there is no correlation than the collateral is valued in the conventional way. For example, if a trader provides t-bills as collateral for an account that has open positions (e.g. short futures) in T-bills, than that trader's account can be credited with some offset since the value of T-bills and T-bill futures are highly correlated.

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.

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.
