A method of preparing data for transmission. The method includes providing a block of data, generating a plurality of first dimension code words including first dimension forward error correction FEC elements, the elements of each code word may be used interchangeably to reconstruct a data portion of the block corresponding to the code word, defining a plurality of second dimension source words formed of the generated elements and generating for at least two of the defined second dimension source words, different numbers of parity elements.

A method of forwarding data transmissions from a first network to a third network via a second network comprises receiving packets of a first type from the first network, segmenting each packet into packets of a second type that are transmitted to the second network, and producing and transmitting at least one encoded duplicate of each of the packets of a second type to the second network to allow a packet of the first type to be recreated in the event that not all the packets of the second type are received. In the event that a sufficient number of the packets of a second type and the encoded duplicate packets are not received to recreate the packet of a first type, the method determines a loss ratio that represents the number of packets not recreated relative to the number of packets transmitted during a selected time interval.

A method of forwarding data transmissions from a first network to a third network via a second network comprises receiving packets of a first type from the first network, segmenting each packet of a first type into packets of a second type, transmitting the packets of a second type to the second network, and producing and transmitting at least one encoded duplicate of each of the packets of a second type to the second network. The encoded duplicate packet allows a packet of the first type to be recreated in the event that not all the packets of the second type are received at the second network. In the event that a sufficient number of the packets of a second type and the encoded duplicate packets are not received to recreate the packet of a first type, the method determines a loss ratio that represents the number of packets not recreated relative to the number of packets transmitted during a selected time interval, dynamically adjusts the overhead required to produce the encoded duplicate packets to attempt to minimize the loss ratio, detects a significant increase in the determined loss ratio over a plurality of the time intervals, successively reduces the overhead required to produce the encoded duplicate packets in response to the detection of a significant increase in the determined loss ratio, and determines whether the reduced overhead requirement stabilizes the determined loss ratio and, if the answer is affirmative, terminates the successive reduction of the overhead requirement.

The invention relates to a method for hydrogen removal of CO mixed gas by selective oxidation. The invention mainly solves the technical problems of low hydrogen removal rate and high CO loss rate in the prior art. The invention adopts hydrogen-containing CO mixed gas as a raw material, allows the raw material to contact a catalyst in a compound bed reactor where inert fillers and the catalyst with platinum-group metals as active components are loaded under a condition with a molar ratio of oxygen and the hydrogen in the raw material of 0.5-5:1, a reaction temperature of 100-300 DEG C, a volume space velocity of 100-10000 h-1, and a reaction pressure of -0.08-5.0 MPa so as to allow the hydrogen in the reaction effluent to be oxidated into water; wherein, on a carrier weight basis, the content of the active component of platinum-group metals is 0.05-1.5%, and the mixing ratio of the inert fillers and the catalyst is 0.1-5:1. The above technical scheme solves the problems well, and the method is applicable to the industrial production of hydrogen removal of CO mixed gas by oxidation.
