A fitting for connecting a pipe which includes a hollow body made in one piece, which extends in a pipe insertion direction about a longitudinal axis. Such problems include, but are not limited to, elevated temperatures and scattering from particles residing within dirty fluid samples. If the position of the packet corresponds to a source packet position, a contribution of the packet to the wildcard packets of the share is computed, and the packet is transmitted as a source packet. A look-ahead feature prevents low-priority wafer transfers from occurring if such transfers would occur just prior to the scheduling of a high-priority wafer transfer.
