Abstract
An Ethernet mapping enables high speed Ethernet data streams having a data rate of 10 Gb/s to be transported across a synchronous packet switched network fabric having a standard SONET OC-192 line rate of 9.953280 Gbaud. The 10 Gb/s Ethernet data stream is compressed by removing interframe gaps between successive MAC frames to produce a compressed data stream, which is then mapped to a synchronous container. The synchronous container is then launched across the synchronous packet switched network fabric at a standard SONET OC-192 line rate of 9.953280 Gbaud. The synchronous container is preferably provided as a stripped STS-192c frame having only A1 and A2 octets of the Transport Overhead (TOH). The compressed data stream is mapped directly to the synchronous container, starting at the first octet following the A1 and A2 octets, without first being inserted into a conventional STS-192c SPE, so that most of the space normally used for TOH and Path overhead (POH) within a conventional STS-192c frame is freed-up for carrying the compressed data stream. At a receiving interface, the compressed data stream is extracted from received synchronous containers and decompressed, by insertion of interframe gaps between successive MAC frames, to generate a recovered 10 Gb/s Ethernet data stream. The starting bit of each successive MAC frame can be identified by examination of the length field of the immediately previous MAC frame.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
