摘要:
A block CRC based fast data hash provides efficient data integrity verification functions. A hash word is generated from block CRCs that are stored along with data blocks in a hard drive for each data and/or parity track of a storage system, such as a RAID array. Each storage system member writes the hash word into a global memory. Thereafter, a director verifies data integrity using all member's hash words with one or more XOR operations. Use of the hash words for data integrity verification saves system bandwidth and CPU processing resources.

A system, method and computer program product are provided for performing a contingent claim valuation of a combination option including one or more multi-stage contingent claims, and an early-launch contingent claim. The method may include determining a first value representing payoffs attributable to exercise of the early-launch contingent claim at a selected decision point; and a second value representing payoffs the attributable to exercise of the multi-stage contingent claim(s) at respective decision point(s), and a contingent claim at an expiration exercise point. The first and/or second values may be determined based upon a respective present value distribution of contingent future value and a respective present value of an exercise price, the present values including a respective distribution and exercise price discounted according to first and second discount rates, respectively. A value of the contingent claim may then be determined based upon the first value and/or the second value.

Embodiments of the present disclosure disclose a data transmission method which includes: sending, by an REC, a first part of downlink data of a downlink period to an RE before the downlink period arrives; sending, by the REC, a second part of the downlink data of the downlink period to the RE in the downlink period, where the second part and the first part constitute all downlink data of the downlink period; receiving, by the RE, the first part and the second part of the downlink data of the downlink period; and sending, by the RE, the first part and the second part as the downlink data through an air interface in the downlink period. Accordingly, the embodiments of the present disclosure also disclose a base station which can effectively improve utilization of transmission bandwidth of a CPRI interface and utilization of spectrum resources of the air interface.
