Abstract: Various embodiments for regulating link speed for performance enhancement and port diagnosis are provided. In response to identifying an amount of errors in a communications link above a predetermined threshold, an applicable transmission speed is selectively reduced. The selective reduction occurs upon one of a temporary, permanent, and user-defined basis, and the selective reduction is performed using one of a manual setting adjustment and speed negotiation logic applied to the communications link. If errors identified at the reduced transmission speed are found to decrease, a communications port incorporating the communications link is flagged as potentially dirty, and if the errors identified at the reduced transmission speed are found to remain constant, the communications port is flagged as potentially bad.

Abstract: A method, system, and computer program product for performing robust, parallel data transfer by a processor device. Data is segmented into k-bit segments, where k?1. The k-bit segments are convolution encoded, using m?1 stages of delay. The n output streams are transmitted in parallel for increased effective data rate, where n>k. The n output streams are received. The n output streams are exclusive-or'ed with pathing allowed by the convolution encoding, in a trellis-decoding diagram. Error-corrected data is identified as an overall path in the trellis-decoding diagram with zero Hamming radius.

Abstract: An approach for managing a data package is provided. Network throughput is determined to exceed a threshold. A sender computer determines a hash digest of the data package by using a hash function selected based on central processing unit utilization. If the hash digest is in a sender hash table, then without sending the data package, the sender computer sends the hash digest and an index referring to the hash digest so that a recipient computer can use the index to locate a matching hash digest and the data package in a recipient hash table. If the hash digest is not in the sender hash table, then the sender computer adds the data package and the hash digest to the sender hash table and sends the data package and the hash digest to the second computer to check the integrity of the data package based on the hash digest.
