Single-lane, twenty-five gigabit ethernet

A method for high-speed data transmission, the method comprising:

• receiving, by a network port logic, first serial binary data via a first communication lane at a first line transmission speed and second serial binary data via a second communication lane at a second line transmission speed, wherein the second transmission line speed is less than the first line transmission speed;
• converting, by a first physical medium dependent sublayer/physical medium attachment sublayer (PMD/PMA) logic of the network port logic, the first serial binary data to first parallel data and, by a second PMD/PMA logic of the network port logic, the second serial binary data to second parallel data;
• decoding, by a physical coding sublayer (PCS) logic of the network port logic and when the network port logic is not in a multi-lane mode, the first parallel data to first decoded parallel data using a first line code also used by a second PCS logic to decode the second serial binary data to second decoded parallel data when the network port logic is not in the multi-lane mode
• converting, by a multi-lane PCS logic coupled to the first PMD/PMA logic and the second PMD/PMA logic and when the network port logic is in the multi-lane mode, a parallel data comprising the first parallel data and the second parallel data to a decoded parallel data using a second line code different than the first line code;
• converting, by a first media access control (MAC) logic of the network port logic coupled to the first PCS logic and when the network port logic is in not in the multi-lane mode, the first decoded parallel data to first Ethernet frame data at a first data rate determined by the first line transmission speed and, by a second MAC logic of the network port logic coupled to the second PCS logic, the second decoded parallel data to second Ethernet frame data at a second data rate determined by the second line transmission speed;
• and
• converting, by a multi-lane MAC logic coupled to the multi-lane PCS logic and when the network port logic is in the multi-lane mode, the decoded parallel data to Ethernet frame data at a data rate comprising a sum of the first and second line transmission speeds.

One or more non-transitory computer-readable storage media comprising a plurality of instructions that in response to being executed cause a network port logic to:

• receive first serial binary data via a first communication lane at a first line transmission speed and second serial binary data via a second communication lane at a second line transmission speed, wherein the second transmission line speed is less than the first line transmission speed;
• convert, by a first physical medium dependent sublayer/physical medium attachment sublayer (PMD/PMA) logic of the network port logic, the first serial binary data to first parallel data and, by a second PMD/PMA logic of the network port logic, the second serial binary data to second parallel data;
• decode, by a physical coding sublayer (PCS) logic of the network port logic and when the network port logic is not in a multi-lane mode, the first parallel data to first decoded parallel data using a first line code also used by a second PCS logic to decode the second serial binary data to second decoded parallel data when the network port logic is not in the multi-lane mode;
• convert, by a multi-lane PCS logic coupled to the first PMD/PMA logic and the second PMD/PMA logic and when the network port logic is in the multi-lane mode, a parallel data comprising the first parallel data and the second parallel data to a decoded parallel data using a second line code different than the first line code;
• convert, by a first media access control (MAC) logic of the network port logic coupled to the first PCS logic and when the network port logic is in not in the multi-lane mode, the first decoded parallel data to first Ethernet frame data at a first data rate determined by the first line transmission speed and, by a second MAC logic of the network port logic coupled to the second PCS logic, the second decoded parallel data to second Ethernet frame data at a second data rate determined by the second line transmission speed;
• and
• convert, by a multi-lane MAC logic coupled to the multi-lane PCS logic and when the network port logic is in the multi-lane mode, the decoded parallel data to Ethernet frame data at a data rate comprising a sum of the first and second line transmission speeds.
