The invention relates to a method for detecting a check-back signal in a transmission system for optical signals.

US07920565B2 Method for updating a data record and device for carrying out the method
When updating a data record identified by a version number, the problem exists that a simple not equal to comparison or greater than comparison is often insufficient for ascertaining the up-to-date nature of the newly received data record, particularly if the data record is transmitted to a receiving station via an unsecured data link and the version number originates from a limited range which is repeatedly run through periodically.The invention solves the problem by virtue of the fact that it divides the range of values of the version number into the ranges “old” and “new”, on the basis of the current value of a version number. The periodicity with which the range of values is run through is taken into account in this case, however. That is to say that the range “old” or the range “new” may perfectly well include the jump from the highest value in the range of values to the lowest value in the range of values. If the version number of the newly received data record lies in the range “new”, the new data record is accepted as a current data record, and if not it is correspondingly rejected.

US07920470B2 Network adapter with TCP support
A network adapter and corresponding method for its use are disclosed. The network adapter has an operational mode that allows a host CPU to offload transmission of a block of data to the adapter. The adapter segments the block into fragments, and builds a data packet for each fragment. The adapter transmits these packets with an adapter-implemented flow control. This flow control uses: a context engine that tracks flow control variables for a “context” established for the block; a context memory for storing the variables; and a receive filter that updates flow control information for the block based on ACK packets received from the remote endpoint receiving the data packets. Because the network adapter implements flow control for data blocks that the network adapter segments, intermediate ACK packets corresponding to that block can be intercepted by the adapter, before they pass to the host, conserving host resources. An added advantage is that the host CPU can offload data blocks larger than the remote endpoint's receive window size, since the adapter can follow the transmit window and transmit packets at appropriate intervals. This further decreases load on the host CPU, decreases latency, and improves bandwidth utilization.
