Abstract: Techniques for transmitting data according to at least one quality of service requirement. A message path is calculated specifying a sequence of broker computers selected from a network of interconnected broker computers. The message path is statistically estimated to fulfill the at least one quality of service requirement. Quality of service metrics are received about the network of interconnected broker computers. If the message path is determined not to fulfill the quality of service requirement, a new message path is calculated specifying a new sequence of broker computers selected from the network of interconnected broker computers. The new message path is statistically estimated to fulfill the at least one quality of service requirement.

Abstract: The present invention discloses a method and system for detecting the frame boundary of a data stream received in Forward Error Correction layer in the Ethernet. The method comprises: intercepting data with the length of a frame from the data stream; validating FEC check for the data with the length of a frame from the start position of the data with the length of a frame; if the FEC check for the data with the length of a frame is not correct, then from the next bit of the ending position of the data with the length of a frame, assuming the data stream position jumping sbn bits as the start position of next frame of data to be intercepted, wherein sbn is an integer that is larger than the pipeline delay of the hardware circuit in FEC layer in the Ethernet and is prime with the length of the frame; returning to the intercepting step; if the FEC check for the data with the length of a frame is correct, the start position of the data with the length of a frame is determined to be the frame boundary position of the data stream. The present invention can increase the speed of frame boundary detection and the speed of frame synchronization without adding any overheads of hardware.
