Abstract
Disclosed are various embodiments for in-band management of Ethernet links utilizing a bit-interleaved parity (BIP) block in a transmission frame. According to various embodiments, a bit-interleaved parity error code may be generated for a monitored portion of network data for transmission in a first bit-interleaved parity block. Subsequently, network management data may be encoded in a plurality of bits for transmission in a second bit-interleaved parity block according to a predefined block code, wherein the predefined block code generates the plurality of bits to maintain a DC balance between the bit-interleaved parity error code and the plurality of bits.
Claims20
A system for in-band network management, comprising:
- a first communication device in data communication with a second communication device, wherein the first communication device is operable to:
- encode a bit-interleaved parity error code for a monitored portion of network data;
- encode network management data in a plurality of bits according to a predefined block code;
- generate a transmission frame comprising a first bit-interleaved parity block including the encoded bit-interleaved parity error code and a second bit-interleaved parity block including at least the encoded network management data;
- and
- transmit the transmission frame from the first communication device to the second communication device.
A method for in-band network management, comprising:
- encoding, by a first communication device, a bit-interleaved parity error code for a monitored portion of network data;
- encoding, by the first communication device, network management information in a plurality of bits according to a predefined block code, wherein the predefined block code generates the plurality of bits to maintain a DC balance between the encoded bit-interleaved parity error code and the plurality of bits;
- generating, by the first communication device, a transmission frame comprising a first bit-interleaved parity block including the encoded bit-interleaved parity error code and a second bit-interleaved parity block including the encoded network management information;
- and
- transmitting the transmission frame from the first communication device to a second communication device.
A non-transitory computer-readable medium embodying a program executable in a processor in data communication with a first communication device, the program comprising code that:
- encodes a bit-interleaved parity error code for a monitored portion of network data in a first bit-interleaved parity block;
- encodes network management data in a plurality of bits for transmission in a second bit-interleaved parity block according to a predefined block code, wherein the predefined block code generates the plurality of bits to maintain a DC balance between the bit-interleaved parity error code and the plurality of bits;
- generates a transmission frame comprising at least the first bit-interleaved parity block and the second bit-interleaved parity block;
- and
- transmits the transmission frame from the first communication device to a second communication device.
