Abstract: A marker spacing between two consecutive alignment marker (AM) blocks is defined for virtual lanes in a multi-virtual-lane networking protocol. A system using the networking protocol includes circuitry configured to identify virtual and physical lane groupings and numbers based on the AM blocks. The system may use error coding groups to allow for distribution of the AM blocks to the physical lanes in integer numbers of error correction blocks. The identification scheme may be based on sequences derived from a known bit pattern and the bit inverse of the bit pattern. The system may include matching units identify instances of the bit pattern and its bit inverse.
